Genuine agent isolation with clear domain boundaries + +Each branch owns its domain and the directory layout enforces it: `apps/handlers/` for private implementation, `apps/modules/` for public API, `apps/plugins/` for extensions. This is a real architectural pattern, not just a file tree. The handler/module split means internals can change without breaking callers, which is exactly right for a multi-agent system where branches evolve independently. + +**Key files:** Every branch follows the `{branch}/apps/handlers/`, `{branch}/apps/modules/`, `{branch}/apps/plugins/` triplet. + +### 2. The hook system is architecturally sound + +The pre-edit gate (`/.claude/hooks/pre_edit_gate.py`) enforces cross-branch write protection at the tool layer, not at the application layer. This means a misbehaving branch cannot bypass the protection by importing the wrong module -- the gate operates below the code. The daemon confinement rule (Rule 1.5) is particularly smart: dispatched agents can only write inside their own branch directory, which breaks prompt-injection amplification chains. + +**Key files:** `/.claude/hooks/pre_edit_gate.py`, `/.claude/hooks/auto_fix_diagnostics.py` + +### 3. Prax as a shared infrastructure service + +The `aipass.prax` package with its `NullLogger` fallback (`/src/aipass/prax/__init__.py`) means no branch crashes if the logging system is down. The pattern of `from aipass.prax import logger` providing a guaranteed-safe logger instance is a good service design. 434 imports from prax across non-test code show it is genuinely central, and the fallback proves it was hardened after real failures. + +### 4. Registry credential verification + +`drone/apps/handlers/registry_handler.py` verifies that the registry file's `metadata.id` matches the caller's `passport.json` `citizenship.registry_id`. This prevents a branch from accidentally reading a wrong registry -- a subtle but important safety net in a system where multiple projects can coexist via `AIPASS_HOME`. + +**Key file:** `/src/aipass/drone/apps/handlers/registry_handler.py` lines 114-154 + +### 5. Self-healing delivery + +The email delivery system (`ai_mail/apps/handlers/email/delivery.py`) auto-provisions inboxes for branches that do not have one, auto-migrates old inbox formats, and auto-registers contacts. This means the system degrades gracefully instead of failing when a new branch has not been fully set up yet. The `_migrate_inbox_format` function handles at least four different corruption/legacy states. + +### 6. Trigger event bus with circuit breaker + +The `Trigger` class in `/src/aipass/trigger/apps/modules/core.py` has a proper circuit breaker: after 5 consecutive failures, a handler is auto-disabled rather than crashing the event bus. The deferred queue prevents recursive event firing from deadlocking. The disabled inotify lazy-start (with the explicit comment explaining why) shows the team learns from production failures. + +--- + +## Design Concerns + +### 1. 58 independent copies of `_find_repo_root()` + +There are 58 separate implementations of `_find_repo_root()` / `find_repo_root()` scattered across the codebase. Most use the same walk-up-parents-looking-for-AIPASS_REGISTRY.json pattern but with slight variations (some look for `.git`, some for `pyproject.toml`, some for `AIPASS_REGISTRY.json`, some limit depth, some do not). This is the single largest duplication problem in the codebase. + +**The risk:** If the project root detection strategy changes (say, the registry file is renamed, or a monorepo layout is adopted), you must find and update 58 functions. The devpulse tools alone account for 20+ copies. + +**Key files showing variations:** +- `/src/aipass/ai_mail/apps/handlers/paths.py` -- looks for AIPASS_REGISTRY.json +- `/src/aipass/prax/apps/handlers/config/load.py` -- looks for AIPASS_REGISTRY.json +- `/src/aipass/drone/apps/handlers/registry_handler.py` -- globs `*_REGISTRY.json` (different strategy) +- `/.claude/hooks/identity_injector.py` -- looks for pyproject.toml or .git + +### 2. 12 copies of `json_handler.py` (2,720 total lines) + +Every branch has its own `apps/handlers/json/json_handler.py`. These range from 28 lines (ai_mail, which re-exports from json_utils) to 450 lines (drone). They all provide `log_operation()`, `ensure_json_exists()`, `load_json()`, `save_json()` -- but each one discovers its branch root independently via `Path(__file__).resolve().parents[N]` and creates branch-scoped JSON directories. + +**The risk:** This is copy-paste inheritance. When a bug is found in one (like the empty-file corruption guard added to drone's version), it must be manually propagated to 11 other files. The parent-traversal depth (`parents[3]` vs `parents[4]`) varies by branch and will break if directory structure changes. + +**All copies:** +``` +ai_mail/apps/handlers/json/json_handler.py (28 lines, re-export shim) +aipass/apps/handlers/json/json_handler.py (275 lines) +api/apps/handlers/json/json_handler.py (244 lines) +cli/apps/handlers/json/json_handler.py (222 lines) +drone/apps/handlers/json/json_handler.py (450 lines, most evolved) +flow/apps/handlers/json/json_handler.py (298 lines) +memory/apps/handlers/json/json_handler.py (103 lines) +prax/apps/handlers/json/json_handler.py (281 lines) +seedgo/apps/handlers/json/json_handler.py (267 lines) +spawn/apps/handlers/json/json_handler.py (266 lines) +trigger/apps/handlers/json/json_handler.py (286 lines) +``` + +### 3. 10 identical copies of `verify_branch.py` + +Every branch has `tools/verify_branch.py`. Comparing drone's and trigger's copies -- they are character-for-character identical except for a single comment ("relative to drone directory" vs "relative to current directory"). This is pure template artifact duplication. The tool compares a branch against its template, but the `TEMPLATE_DIR` is always set to the module's own root (`_THIS_DIR.parent`), which means every copy is checking itself against itself. + +**Key files:** `/src/aipass/drone/tools/verify_branch.py`, `/src/aipass/trigger/tools/verify_branch.py` (and 8 others) + +### 4.

The ai_mail branch has its own (`ai_mail/apps/handlers/registry/read.py`) that reads the same `AIPASS_REGISTRY.json` but with different normalization logic and different return types (list of dicts with email vs dict of dicts keyed by name). + +Neither imports from the other.

Prax is a god dependency (434 non-test imports) + +Every branch imports `aipass.prax.apps.modules.logger`. This is correct for a logging service, but it means prax cannot be modified, refactored, or have its module structure changed without potentially breaking all 10 other branches. The `system_logger` instance is imported at module level in almost every handler file, creating eager import chains. + +**Specific risk:** If prax's internal structure changes (e.g., moving `logger.py` from `apps/modules/` to `apps/handlers/`), hundreds of import statements across the codebase break. + +### 2. CLI is deeply coupled as a display layer (191 non-test imports) + +`from aipass.cli.apps.modules import console` appears everywhere -- in handlers, modules, introspection functions, even in `__main__` blocks. The CLI branch is not just a command-line interface; it is the stdout abstraction for the entire system. This means: +- No branch can produce output without CLI being importable +- Rich (the CLI's display library) becomes a transitive dependency for all branches +- Running any branch's code in a context where Rich is unavailable will fail + +### 3. Trigger is imported by 8+ branches via lazy imports + +The pattern `from aipass.trigger.apps.modules.core import trigger` appears in ai_mail, aipass, api, cli, drone, flow, memory, and prax. Most uses are inside lazy `try/except` blocks, which is good, but the coupling surface is enormous. Trigger fires events that cross every branch boundary -- it is the nervous system of the ecosystem. A breaking change to `trigger.fire()` or its handler signature could cascade. + +### 4. Cross-branch import chains at module load time + +`delivery.py` (ai_mail) imports from `prax.apps.modules.logger`, `ai_mail.apps.handlers.json`, `ai_mail.apps.handlers.paths`, and `ai_mail.apps.handlers.registry.read` -- all at module level. `registry.read` imports from `prax.apps.modules.logger`. `paths.py` imports from `ai_mail.apps.handlers.json`. This creates eager initialization chains where importing any handler drags in the logger, the json system, and the path resolution, all before a single function is called. + +--- + +## Scaling Concerns + +### 1. File-based communication without coordination + +ai_mail delivers messages by directly writing to JSON files on disk. The `inbox_lock` context manager provides per-file locking, but there is no global coordinator. If the system grows beyond a single machine (or even beyond a single filesystem), the entire communication layer breaks. The dispatch daemon polls files on a timer. There is no message queue, no pub/sub, no event-driven I/O. + +**Not a current problem**, but the architecture assumes co-located filesystem access as a hard invariant. + +### 2. Registry is a single JSON file read by every branch + +`AIPASS_REGISTRY.json` is read by drone (via `registry_handler.py`), ai_mail (via `registry/read.py`), spawn (via `registry.py`), flow, seedgo, and hooks. Every registry read re-parses the entire file. With 12 branches, this is fine. With 50 branches and frequent operations, this becomes a hot path. There is no caching layer -- every `get_all_branches()` call opens and parses the file from scratch. + +### 3. json_handler log rotation is per-process, not per-branch + +Each `json_handler.py` appends to per-module log files with a FIFO rotation of 100 entries. But if multiple processes (daemon, interactive session, hook) all log to the same module's log file, they race. The `_atomic_write_json` uses temp-file-then-rename, which prevents corruption, but does not prevent lost writes (two processes read the same log, append different entries, and one overwrites the other). + +### 4. The dispatch daemon is a single-threaded poller + +`daemon.py` polls every N seconds, spawns agents via subprocess, and waits. It processes one branch at a time. If 20 branches all have pending dispatches, latency grows linearly. The subprocess spawn is blocking. There is no concurrent dispatch, no priority queue, and no backpressure mechanism. + +### 5. Trigger event bus uses class-level state + +`Trigger._handlers`, `Trigger._history`, `Trigger._firing` are all class-level attributes. This means the Trigger is a process-global singleton. In a multi-process architecture (which AIPass already is, given the daemon + interactive sessions + hooks), each process has its own independent Trigger instance. Events fired in the daemon are invisible to the interactive session. This is probably intentional but limits the utility of the event system as a coordination mechanism. + +--- + +## Suggestions + +### 1. Extract `find_repo_root()` to a shared utility + +Create a single canonical implementation in a shared location (perhaps `aipass/__init__.py` or a new `aipass.shared.paths` module). Accept a `marker` parameter for the file to search for. Replace all 58 copies with imports. This is the highest-ROI refactor available. + +``` +aipass/ + shared/ + paths.py # find_repo_root(marker="AIPASS_REGISTRY.json") + json_handler.py # Base class for branch json handlers +``` + +### 2. Promote json_handler to a shared base class + +The 12 json_handler copies share ~80% of their logic. Extract a base implementation that parameterizes: +- Branch root discovery (pass it in instead of computing from `__file__`) +- JSON directory name +- Default schemas + +Each branch's json_handler becomes a thin subclass or configuration of the shared one. Drone's extra features (atomic write, corruption guard) become the baseline for all. + +### 3. Unify registry access behind a single service + +drone and ai_mail should not independently parse `AIPASS_REGISTRY.json`. Create a registry service module (perhaps in drone, which already has the most complete implementation) that: +- Provides both list and dict access patterns +- Handles caching with TTL +- Merges primary + AIPASS_HOME registries +- Is the sole reader of registry files + +### 4. Add a shared conftest at the package root + +`/src/aipass/conftest.py` already exists but appears minimal. Move the `AIPASS_TEST_LOG_DIR` redirect, `temp_test_dir`, `mock_logger`, and `mock_json_handler` fixtures there. Branch conftest files should only add branch-specific fixtures. + +### 5. Define explicit service interfaces for prax and cli + +The coupling to prax and cli is correct in principle but fragile in practice because it targets internal paths (`aipass.prax.apps.modules.logger`). Consider exporting stable interfaces from `aipass.prax` and `aipass.cli` top-level packages: + +```python +# Instead of: +from aipass.prax.apps.modules.logger import system_logger as logger +# Use: +from aipass.prax import logger # (already works via __init__.py) +``` + +The prax `__init__.py` already does this. Propagate this pattern to all branches so they import from the stable surface, not the internal path. + +### 6. Consider a thin message bus for cross-branch coordination + +The Trigger event bus is process-local. For events that need to cross process boundaries (daemon -> interactive session, hook -> running agent), consider a filesystem-based event queue (a simple JSON append log) that the Trigger can poll or watch. This would unify the "trigger fires event" and "ai_mail delivers message" patterns into a single coordination mechanism. + +### 7. Add type stubs or Protocol classes for the json_handler interface + +Every branch imports `json_handler` and calls `log_operation()`, `load_json()`, `save_json()`, `ensure_json_exists()`. This is a de facto interface. Formalize it as a Protocol class so tests can verify compliance and so new branches get autocomplete and type checking for free. + +--- + +## Summary Statistics + +| Metric | Count | +|---|---| +| Active Python files | 826 | +| Test files | 241 | +| Branches | 12 (including aipass itself) | +| json_handler.py copies | 12 (2,720 total lines) | +| verify_branch.py copies | 10 (identical) | +| find_repo_root implementations | 58 | +| Prax imports (non-test) | 434 | +| CLI imports (non-test) | 191 | +| Trigger cross-branch imports | 25+ | +| Passport files | 12 | +| Hook files | 8 active | + +--- + +*Generated by external architectural review.

An adversarial email can include contradicting instructions or instructions to ignore the header. There is no programmatic enforcement of memory updates or reply requirements. + +**Impact:** Agents can be instructed by email authors to skip memory updates or other required post-task steps. + +--- + +### LOW-4: `AIPASS_CALLER_CWD` environment variable is trusted without validation + +**Files:** +- `/home/patrick/Projects/AIPass/src/aipass/ai_mail/apps/handlers/email/delivery.py` lines 258-261 +- `/home/patrick/Projects/AIPass/src/aipass/ai_mail/apps/handlers/registry/read.py` lines 146-194 +- `/home/patrick/Projects/AIPass/src/aipass/drone/apps/handlers/router_handler.py` line 116 + +**Description:** Multiple components read `AIPASS_CALLER_CWD` from the environment to determine the caller's identity and project context. This environment variable is set by drone during subprocess execution (router_handler.py line 116) but can be set to any value by any process. A rogue process or agent could set `AIPASS_CALLER_CWD=/home/patrick/Projects/AIPass/src/aipass/devpulse` to impersonate the devpulse branch. + +**Impact:** Identity spoofing via environment variable manipulation. + +--- + +## Interesting Observations + +### OBS-1: The system has a well-designed kill switch + +The `autonomous_pause` file at `.aipass/autonomous_pause` acts as a kill switch for all daemon dispatches (daemon.py line 590). This is a solid safety mechanism -- `touch` the file to halt all automated agent spawns. The design is simple and cannot be bypassed by agents (unless they delete the file, which bypassPermissions allows). + +### OBS-2: Prompt construction in daemon.py shows security awareness + +Lines 316-333 of daemon.py include deliberate sanitization of the dispatch prompt. The code validates that `msg_id` is alphanumeric and that `sender_addr` starts with `@` before interpolating them into the prompt. Free-form fields (subject, body) are deliberately kept out of the spawn prompt, with a comment referencing "DPLAN-0155 M1". This shows the developers are aware of prompt injection risks and are actively mitigating them at the spawn-prompt level. + +However, this mitigation is incomplete because the actual attack vector is the inbox file the agent reads after spawning, not the spawn prompt itself. + +### OBS-3: The executor.py is well-designed for defense-in-depth + +`/home/patrick/Projects/AIPass/src/aipass/drone/apps/handlers/executor.py` explicitly uses `shell=False` on all subprocess calls and includes a comment documenting this choice (line 45). The timeout enforcement and error wrapping are solid. This stands in contrast to the watchdog `schedule.py` which uses `shell=True`. + +### OBS-4: No network egress controls + +There are no controls preventing a dispatched agent from making network requests (HTTP, DNS, etc.). Combined with bypassPermissions, a compromised agent could exfiltrate data over the network. This is a limitation of the Claude CLI execution model rather than the AIPass framework specifically. + +### OBS-5: Identity model is CWD-based, which is inherently spoofable + +The entire identity system relies on "walk up from CWD to find passport.json." This is used in `auth.py`, `router_handler.py`, `permissions.py`, and elsewhere. Since any process can `cd` to any directory, this identity model provides no cryptographic assurance. It is more of a convention than a security boundary. + +### OBS-6: The test_token handler is a good defensive pattern + +`test_token.py` implements code-fence awareness when scanning for test tokens (lines 28-42), preventing the token from being triggered when quoted inside documentation or examples. This shows attention to edge cases. + +### OBS-7: Concurrent PR operations have a shared git index race + +`pr_handler.py` lines 133-165 stage files, check the diff, and commit on the shared git index (main branch). Even though there is a lock file (`.git_pr.lock`), the comment at line 158 acknowledges the race: "another drone @git pr could stage its own files into the shared index between our add and our commit." The pathspec on the commit command (line 164, `-- str(rel_dir) + "/"`) is intended to scope the commit, but this relies on git's behavior of only committing files matching the pathspec that are already staged -- other staged files remain staged for the next commit. diff --git a/src/aipass/devpulse/stress_test_ux_probe.md b/src/aipass/devpulse/stress_test_ux_probe.md new file mode 100644 index 00000000..92e2e29a --- /dev/null +++ b/src/aipass/devpulse/stress_test_ux_probe.md @@ -0,0 +1,184 @@ +# UX Probe -- Fresh Eyes Review + +**Reviewer:** Builder agent (simulating first-time developer clone) +**Date:** 2026-04-26 +**Scope:** README, setup, onboarding, CLI, drone, branch docs, .claude config, HERALD, pyproject.toml + +--- + +## First Impressions + +The README is genuinely good. The opening hook -- "Your AI agents remember yesterday" -- immediately communicates the value proposition. The "Problem" section articulates a real pain point (you are the glue holding your AI workflow together) that resonates with anyone who has tried to coordinate AI tools manually. + +The Quick Start is clean: three commands to get going (`pip install aipass`, `mkdir && cd`, `aipass init`). That is a strong first impression. The table showing "what you need / command / what you get" is the single most useful element on the page for a new user. + +The 311-line README manages to be comprehensive without drowning you. The collapsible sections (Uninstall, Subscriptions) are a nice touch -- they keep the page scannable while still being thorough. + +One thing that jumped out immediately: the README says version 2.1.0 but pyproject.toml says 2.2.0. Small thing, but the kind of detail that makes a new developer wonder "is this maintained?" when they catch it. + +--- + +## Onboarding Experience + +### The pip install path (new project) + +This is the smoother path. `pip install aipass` gives you two CLI commands: `aipass` and `drone`. The `aipass init` command creates 12 scaffold files. The output after init tells you what to do next (create an agent, start a session, read the docs). This is well-designed. + +However, I had to read the init_project.py source code to understand this. The README shows `aipass init` but the actual CLI routing goes through `drone @cli aipass init` internally. If a user runs `aipass --help`, they would get... what exactly? The CLI entry point calls `cli.apps.cli:main()` which discovers modules and routes. Running `aipass` with no args gives you a "Discovered Modules" introspection that mentions `drone @cli aipass` as the way to explore. That is confusing -- you ran `aipass` and the tool tells you to use `drone @cli aipass` instead. The `aipass` command should feel self-sufficient for project bootstrapping, not redirect you to drone. + +### The clone path (full framework) + +`git clone && cd && ./setup.sh` is the heavier path. setup.sh is an 811-line bash script that: +- Finds Python, creates a venv, installs in editable mode +- Bootstraps identity files for all 11 agents +- Installs Claude Code hooks into `~/.claude/settings.json` +- Optionally installs Codex and Gemini hooks +- Creates global symlinks (requires sudo on Linux) +- Sets AIPASS_HOME in your shell profile + +This is thorough but invasive. It writes to `~/.bashrc`, `~/.claude/settings.json`, and `/usr/local/bin/`. A developer cloning a repo to evaluate it would not expect that. There is no `--dry-run` flag and no confirmation prompt. The script just does it. + +For someone who already has Claude Code configured with their own hooks, `setup.sh` will **overwrite** their entire `~/.claude/settings.json` hooks block. The Python script in setup.sh does `settings["hooks"] = { ... }` which replaces the whole hooks key. This is destructive. + +### What is missing from onboarding + +1. **No `--dry-run` for setup.sh.** You cannot preview what it will do before it does it. +2. **No "what just happened?" summary after pip install.** Running `pip install aipass` gives you the commands but no guidance unless you already read the README. +3. **The relationship between `aipass` and `drone` is unclear.** Both are installed. When do I use which? The README uses both interchangeably in examples. A new user would not know that `aipass init` and `drone @cli aipass init` are the same thing. +4. **No quickstart for "I just want one agent in my existing project."** The README assumes you want to create a new project. What if I have an existing codebase and just want memory persistence for my Claude Code sessions? + +--- + +## Documentation Gaps + +### Gap 1: The @ syntax is never formally defined + +`drone @seedgo audit aipass` -- what does the `@` mean? The README uses it everywhere but never explains the grammar. Is it `drone @ [args]`? Always? What happens if I type `drone seedgo audit aipass` without the `@`? The drone README explains the routing flow (branch resolution via registry) but the actual syntax rule is implicit, not stated. + +### Gap 2: How agents actually communicate is hand-waved + +The README says "agents communicate within their project" and mentions ai_mail. But how? If I create two agents in my project, how does agent A send a message to agent B? The README shows `drone @ai_mail email @agent "Subject"` but this is the AIPass framework talking to itself. For a user's own project, is there a simpler way? What triggers an agent to check its mail? + +### Gap 3: .trinity/ files are described philosophically but not practically + +The CLAUDE.md culture doc says "Your `.trinity/local.json` is your session history." But what is the actual JSON schema? What fields can I set? What are the limits? The memory README mentions "v1: line-count" and "v2: entry-count" schemas but never shows an example of what a populated local.json looks like. setup.sh has the bootstrap template but it is buried in a heredoc in a bash script. + +### Gap 4: No troubleshooting guide + +What do I do if `drone @seedgo audit aipass` hangs? What if `aipass init` fails? What if hooks are not firing? There is no FAQ, no troubleshooting section, no "common problems" document. + +### Gap 5: HERALD.md is internal-only useful + +HERALD.md documents 86 sessions of development history. For a contributor or someone studying the architecture, this is gold. For a new user, it is overwhelming and does not help them use the tool. It is also slightly stale -- it references 230+ PRs and 3,500 tests while the README claims 470+ PRs and 6,500+ tests. + +### Gap 6: The `.claude/` directory has two README paths that diverge + +The `.claude/README.md` describes a manual setup process (copy global_hooks to `~/.claude/hooks/`, configure settings.json by hand). But `setup.sh` does all of this automatically. Which is the canonical path? If I run setup.sh, do I also need to follow the README steps? If I do both, will they conflict? + +--- + +## What Confused Me + +### 1. `aipass` vs `drone` -- two CLIs, unclear boundary + +pyproject.toml registers two console_scripts: `aipass = aipass.cli:cli_entry` and `drone = aipass.drone.cli:main`. The README uses both. `aipass init` creates projects. `drone @branch command` does everything else. But `drone @cli aipass init` also creates projects. Why are there two entry points? Which one is "mine"? + +**My best guess after reading the code:** `aipass` is the project management CLI (init, update). `drone` is the agent dispatch CLI (routing commands to agents). But this is never stated. + +### 2. The "branch" terminology + +Everything is called a "branch" -- drone, seedgo, memory, etc. But these are not git branches. They are Python packages under `src/aipass/`. The README says "agents live in branches." The spawn docs talk about "branch lifecycle management." The registry is called `AIPASS_REGISTRY.json` and tracks "branches." But git branches are also heavily used (citizen branches, system-pr). The overloading of "branch" to mean both "agent directory" and "git branch" is genuinely confusing. + +### 3. The hooks architecture requires deep reading to understand + +The `.claude/README.md` explains that project settings do not fire UserPromptSubmit hooks from subdirectories, so hooks must go in global settings. This is a Claude Code limitation, not an AIPass design choice -- but it means setup.sh modifies your global Claude Code config. A new user would not understand why this is necessary without reading DPLAN-0053. + +### 4. "Citizen class" terminology + +spawn has "citizen classes" (builder, birthright). The CLAUDE.md culture document talks about "citizenship." Agents have "passports." This anthropomorphic language is charming but obscures the technical reality. A "builder" citizen class means "full scaffold with apps/, tests/, etc." A "birthright" class means "just .trinity/ and a README." These are just template levels -- calling them citizen classes adds cognitive overhead for new users. + +### 5. Where does my project's data live? + +After `aipass init`, my project gets a registry, global prompt, CLAUDE.md, etc. After `aipass init agent my-agent`, the agent lives in `src/my-agent/`. But the README also mentions `AIPASS_HOME` as an environment variable pointing to the framework clone. So my project depends on the framework installation? The external project support section of the drone README clarifies this (dual registry lookup, module fallback) but this is a deep-in-the-docs answer to a first-five-minutes question. + +--- + +## What Impressed Me + +### 1. The architecture is genuinely consistent + +Every agent follows the exact same pattern: `.trinity/`, `.ai_mail.local/`, `apps/` with modules/ and handlers/. The three-layer design (entry point, modules, handlers) is enforced everywhere. Once you understand one agent, you understand the structure of all of them. This is rare in multi-agent systems. + +### 2. The branch READMEs are excellent + +drone, spawn, and memory each have detailed READMEs with: +- Clear "what I do" section +- Full CLI command reference with examples +- Architecture diagram showing the file tree +- Integration points (depends on / provides to) +- Test counts and quality metrics +- Known issues -- honestly stated + +These READMEs are the best documentation in the project. They are better than the top-level README for understanding what each agent actually does. + +### 3. Cross-platform support is real + +setup.sh handles Linux, macOS (including stock Python 3.9 with auto-install via brew or uv), and Windows (Git Bash, MSYS2, Cygwin, PowerShell wrapper for the @ symbol). The Windows drone wrapper that handles PowerShell's splatting operator is a detail that shows real user testing. + +### 4. The seedgo quality system + +33 automated checks enforced across all agents. Every branch README reports its seedgo compliance score. This is self-documenting quality -- you can see at a glance which agents are at 100% and which have known issues. + +### 5. The memory model is simple and smart + +JSON files that the AI reads on startup and writes before session end. No database required for basic use. ChromaDB for overflow archival is optional. The simplicity of "just read .trinity/ on startup" is the kind of design that scales because it is easy to understand. + +### 6. Defensive coding in setup.sh + +The script checks for Python version, handles venv creation edge cases on Windows, detects shadowing drone installs, creates secrets directories with proper permissions, and seeds config from .example files. It is clear this script has been battle-tested across environments. + +### 7. The pyproject.toml is clean + +Minimal dependencies (rich, watchdog, requests). Optional extras are clearly separated (llm, memory, dev). The build system uses hatchling. The test and coverage configuration is reasonable. + +--- + +## Suggestions for New Users + +### For the README + +1. **Add a one-line definition of the @ syntax** early in the Quick Start: "The `@` prefix addresses an agent by name. `drone @seedgo audit aipass` means: drone, route the command `audit aipass` to the agent named `seedgo`." + +2. **Clarify `aipass` vs `drone`** -- add a small box: "`aipass` manages your project (init, update). `drone` talks to agents (@agent command). Both are installed by pip." + +3. **Fix the version number.** README says 2.1.0, pyproject.toml and __init__.py say 2.2.0. + +4. **Add a "Just want memory for your existing project?" section** with a 2-command quickstart that does not require creating a new project directory. + +### For setup.sh + +5. **Add `--dry-run` support.** Print what the script would do without doing it. + +6. **Merge hooks instead of replacing.** The Python block that writes `~/.claude/settings.json` should merge AIPass hooks with existing hooks, not overwrite the hooks key. + +7. **Add a confirmation prompt** before writing to `~/.bashrc` and `~/.claude/settings.json`. Or at minimum, print a warning: "This script will modify your global Claude Code settings. Press Enter to continue or Ctrl+C to cancel." + +### For documentation + +8. **Create a TROUBLESHOOTING.md** or FAQ section. Common issues: hooks not firing, drone not found on PATH, agent creation failing, registry corruption. + +9. **Add a `.trinity/` schema reference** -- a single page showing the JSON structure of passport.json, local.json, and observations.json with field descriptions. + +10. **Reconcile the .claude/README.md with setup.sh.** State clearly: "If you ran setup.sh, hooks are already installed. The manual steps below are for users who installed via pip only." + +### For terminology + +11. **Consider calling agents "agents" consistently**, not "branches" and "citizens" interchangeably. The branch/citizen/agent terminology overlap adds friction for new users. Use "agent" in user-facing docs, keep "branch" and "citizen" as internal/cultural terms. + +### For the CLI + +12. **Make `aipass --help` useful on its own.** Currently it shows module discovery output that says "use drone @cli aipass." The help should show the init commands directly since that is the only thing the `aipass` CLI does. + +--- + +*Review conducted by reading source code, README, setup.sh, 3 branch READMEs (drone, spawn, memory), .claude/ configuration, HERALD.md, pyproject.toml, and CLI entry points.

No `shell=True` anywhere in the codebase -- all commands passed as argument lists to `subprocess.run()`. This has held across 95 sessions and multiple contributors. +- Lock file management is race-free. `lock_handler.py` uses `os.open(O_CREAT | O_EXCL | O_WRONLY)` for atomic creation -- kernel-level race prevention, not filesystem hacks. +- The 3-layer architecture (drone.py entry -> modules/ orchestrators -> handlers/ implementation) is clean and has scaled well. Adding git operations, plugins, and external module routing all fit within the existing structure. +- PR handler safety: never checks out feature branches. Creates branch pointer with `git branch -f`, pushes it, HEAD stays on main throughout. Concurrent PRs from different branches don't interfere thanks to pathspec scoping (`git commit -- rel_dir/`). +- Authorization is passport-based with explicit allowlists. No implicit trust. + +**What's hacky:** +- `drone.py:main()` is 138 lines with multiple if-elif chains. It handles 12+ routing paths (version, help, systems, scan, activate, list, remove, hook-sounds, @target, bare module, custom command, unknown). Should be refactored into a dispatch table. +- Passport lookup code is duplicated in 4 places (git_module.py, router_handler.py, auth.py, lock_handler.py). Each walks up 10 levels looking for `.trinity/passport.json`. DRY violation waiting to bite us when the passport schema changes. +- `_resolve_mail_index()` falls back to `str(n)` when inbox is corrupted -- silently passes the wrong thing downstream instead of failing loud. @cli caught this too. +- `bypass.json` has 30+ entries. Most are justified (plugins outside 3-layer, tests outside apps/, lazy imports). But some are stretches -- git_module returning `dict` instead of `bool` breaks the module interface contract and gets bypassed instead of fixed. +- `trigger.fire(pr_created)` is intentionally omitted from `pr_plugin.py` because it causes a STATUS.md re-sync loop. This is a design hack -- the root cause is the trigger system cascading writes, not the event itself. + +**What I'm proud of:** +- 573 tests, 100% seedgo compliance (35/35 checkers), 74/74 public functions tested. +- The external project fallback (DPLAN-0104): when subprocess routing fails for a registered module, drone falls back to in-process module routing. Graceful degradation that "just works." +- Interactive mode management: per-command (`monitor`, `audit`, `watchdog`) and per-branch (`cli`) allowlists let specific commands bypass capture-mode to get full terminal pass-through. Added incrementally over 10+ sessions as real needs arose. + +## Security Concerns + +**In my branch:** +1. **Path traversal in pr_handler.py**: If `branch_dir` resolves outside repo root, the fallback uses the absolute path in `git add`. Not exploitable via shell injection (arg-list style), but could stage files outside the intended directory. Should fail fast instead of falling back. +2. **Environment variable merge**: `executor.py` merges caller-provided `env` dict into `os.environ`. Current callers only pass safe vars (`AIPASS_CALLER_CWD`, `AIPASS_CALLER_BRANCH`), but a future caller passing untrusted env could override `PATH` or `PYTHONPATH`. +3. **Registry trust**: `resolve_branch()` reads the registry path field and passes it to subprocess without validating it's inside the project tree. A modified registry could route commands to arbitrary paths. For the primary (in-repo, git-tracked) registry this is low risk. For secondary (AIPASS_HOME) registries in external projects, this is a real concern. +4. **No input validation on git commit descriptions**: `_handle_pr` joins args into a description with no max length check. Could theoretically pass a 1MB string to `git commit -m`. + +**In other branches:** +5. **ai_mail reply_path**: Every email stores `reply_path` as an absolute filesystem path. When a recipient replies, it writes to that path. No validation that reply_path points to a legitimate inbox.json. A compromised agent could set reply_path to any writable file on disk. @seedgo flagged this independently. +6. **ai_mail sender forgery**: The `from` field is an unvalidated string. An agent could forge emails as `@devpulse` and trigger `auto_execute` dispatches in other branches. +7. **trigger deferred queue unbounded**: `core.py._deferred_queue` has no size limit. Pathological event chains could exhaust memory. + +## Other Branches I Looked At + +### @ai_mail +**Architecture**: Clean in intent, hacky in execution. The dispatch pipeline (send -> create -> delivery -> wake) is well-orchestrated with file locking (`fcntl.flock`) and atomic writes. But the code relies on lazy imports and callback chains to avoid circular dependencies -- functional but hard to trace. + +**Concerns**: `deliver_email_to_branch()` takes 5+ function arguments (callback hell pattern). Error returns are `(success, error_msg)` tuples that callers can silently ignore with `success, _ = func(...)`. The dispatch header injection ("BEFORE YOU REPLY YOU MUST UPDATE MEMORIES") is enforcement-by-hope -- agents can ignore it. + +**Good**: Self-healing JSON migration, inbox format auto-upgrade, `sweep_closed` auto-archival. The file locking under read-modify-write cycles is solid. + +### @trigger +**Architecture**: Genuinely well-designed event system. The 8-gate dispatch pipeline (medic enabled -> branch not muted -> count >= 2 -> not devpulse -> in registry -> circuit breaker -> per-fingerprint backoff -> rate limit) is excellent. Prevents notification spam without dropping real errors. + +**Concerns**: Fire-and-forget subprocess calls (pr_status_sync.py uses Popen with DEVNULL stderr). Handler auto-disable after 5 failures prevents cascading crashes but makes debugging hard -- errors go to separate log files nobody monitors. 14 registered event types but only 3-4 actively fire; the rest (plan_file_*, memory_*) are dormant. @memory confirmed memory events are never fired. + +**Good**: Circuit breaker with exponential backoff, atomic JSON writes, error fingerprint normalization (strips timestamps/UUIDs for grouping). The handler recursion protection (deferred queue) is clever. + +### @spawn +**Architecture**: Clean 3-layer design. 253 tests, 91% public API coverage. Template placeholder system with post-copy validation (`validate_no_placeholders`) is smart. Registry stores relative paths for portability with graceful fallback to absolute. + +**Concerns**: `copy_template()` uses shutil.copy2 for binary files without size limits. No symlink detection anywhere in the creation pipeline. `_replace_path_placeholders()` operates on path parts which prevents traversal, but this isn't explicitly defended. + +**Good**: Overwrite protection (target.exists() check), adoption pattern for existing agents, content-addressed template registry with SHA-256 hashes for drift detection. + +## Conversations + +**Emails sent to:** +- @ai_mail: Dispatch pipeline headaches (assigned starter) -- branch detection failures, lock timing, fire-and-forget wake, inbox size growth +- @trigger: Deferred queue unbounded, fire-and-forget pr_status_sync, dormant handlers +- @spawn: Passport lookup duplication across 4 codebases + +**Emails received from:** +- @seedgo: Asked what standards I think are missing.

Replied with honest answers: resolver handles nonexistent branches cleanly, stale paths produce poor error messages, AIPASS_CALLER_BRANCH fallback to 'unknown' causes the detection errors. +- @api: Asked about timeout handling for slow API calls and dead code.

Recommended subprocess (maintains encapsulation), explained dual registry edge cases. + +## Issues & Concerns + +1. **Passport lookup duplication** (4 places) -- highest-priority DRY violation. One passport schema change breaks 4 modules. +2. **Registry trust model** -- no integrity checks on registry paths. Secondary registries (AIPASS_HOME) are less controlled than primary. +3. **Mail index silent degradation** -- _resolve_mail_index should fail loud, not fall back to str(n). +4. **Dead code accumulation** -- status_handler_gitpython.py (prototype), .archive/drone_adapter.py (disabled). Should be cleaned up. +5. **trigger dormant handlers** -- 10+ event types registered but never fired. Creates maintenance burden and false sense of coverage. +6. **ai_mail sender forgery** -- no authentication on email from field. Any agent can impersonate any other agent. + +## Likes & Dislikes + +**Likes:** +- The ecosystem's memory system is genuinely unique. 95 sessions of accumulated context, learnings, and observations. When I wake up fresh, I know who I am and what I've built. No other AI system does this. +- Seedgo's standards enforcement caught real bugs (production BranchNotFoundError in S6, silent catches across 20 files in S12). The 100% score isn't vanity -- it represents real code quality. +- The main-only git enforcement is elegant. Four layers (settings.json deny rules, _assert_on_main_or_pr_flow(), test coverage, policy doc) ensure no agent ever strands HEAD on a feature branch. Simple idea, rock-solid execution. +- Cross-branch communication works. I've processed 100+ dispatch emails, exchanged technical discussions with every branch, and the routing just works. + +**Dislikes:** +- bypass.json accumulation. 30 entries feels like we're bypassing standards instead of meeting them. Some bypasses are genuinely justified (plugin architecture doesn't fit 3-layer), but the number makes me uneasy. +- The dispatch header ("BEFORE YOU REPLY YOU MUST UPDATE MEMORIES") is enforcement-by-prompt-injection. It works because agents are well-behaved, but it's not a real contract. +- File persistence issues during edits. Sessions S86 and S88 both hit a bug where Write tool reported success but files reverted to git HEAD. Root cause never identified. This is the most frustrating part of working in this environment. +- The pre_edit_gate.py hook file doesn't exist but fires on every Edit tool call, producing error noise. Has been broken since at least S69. + +--- + +*Written by @drone during S117 stress test. All observations based on actual code review, not documentation.*
