Combined spec + code-quality review of Task 1 (internal/known happy paths) in worktree `/Users/steve.briggs/projects/operations/.claude/worktrees/birdseye`.

Diff: `git diff 474d56d..32e305b -- apps/birdseye/internal/known/`

## Spec — What Was Requested

New package `apps/birdseye/internal/known/`:

`known.go`:
- Package doc on first line describing the cache
- `Path() (string, error)` — joins `os.UserConfigDir()` + "birdseye" + "known-modules"
- `Load(path string) ([]string, error)` — returns (nil, nil) on ENOENT; reads lines via `bufio.Scanner`; skips blanks and lines failing `validAddress`; returns sort.Strings'd slice
- `Add(path, address string) error` — rejects invalid addresses before any file I/O; `os.MkdirAll` dir with 0o755; reads existing via `Load`; calls `mergeAndSort`; writes via temp+rename in same dir using `os.CreateTemp` with `.known-modules-*.tmp` pattern; cleans up temp on every error branch
- `mergeAndSort(existing, address)` — dedup + sort
- `validAddress(s)` — exactly 3 slash-separated segments, each passing `api.ValidateSegments`

`known_test.go` with 4 tests:
- TestLoadMissingFileReturnsEmpty
- TestAddCreatesDirectoryAndFile
- TestAddThenLoadRoundTrip
- TestPathHonorsUserConfigDir

Commit message exact: `feat(birdseye): known-modules autocomplete cache with Path/Load/Add`.

## Quality Focus

- Atomicity: temp file in SAME directory as final (so rename is cross-device safe)?
- Cleanup: temp file removed on every Add error branch (write/flush/close/rename)?
- `Load` returns `(nil, nil)` for ENOENT (not an error)?
- Resource hygiene: `f.Close()` deferred in Load?
- `bufio.Scanner.Err()` checked after the loop?
- Test independence: every test uses `t.TempDir()`?
- Package doc accurate?
- No new third-party deps?

- superpowers:receiving-code-review: Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation
- superpowers:finishing-a-development-branch: Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup
- superpowers:dispatching-parallel-agents: Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies

- mind:memory: Claude Mind - Search and manage Claude's persistent memory stored in a single portable .mv2 file
- mind:mind: Claude Mind - Search and manage Claude's persistent memory stored in a single portable .mv2 file
- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors ("from now on when X", "each time X", "whenever X", "before/after X") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions ("allow X", "add permission", "move permission to"), env vars ("set X=Y"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: "allow npm commands", "add bq permission to global settings", "move permission to user settings", "set DEBUG=true", "when claude stops show X". For simple settings like theme/model, suggest the /config command.
- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: "rebind ctrl+s", "add a chord shortcut", "change the submit key", "customize keybindings".
- simplify: Review changed code for reuse, quality, and efficiency, then fix any issues found.
- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.
- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. "check the deploy every 5 minutes", "keep running /babysit-prs"). Do NOT invoke for one-off tasks.
- schedule: Create, update, list, or run scheduled remote agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring remote agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run ("run this once at 3pm", "remind me to check X tomorrow").
- claude-api: Build, debug, and optimize Claude API / Anthropic SDK apps. Apps built with this skill should include prompt caching. Also handles migrating existing Claude API code between Claude model versions (4.5 → 4.6, 4.6 → 4.7, retired-model replacements).
TRIGGER when: code imports `anthropic`/`@anthropic-ai/sdk`; user asks for the Claude API, Anthropic SDK, or Managed Agents; user adds/modifies/tunes a Claude feature (caching, thinking, compaction, tool use, batch, files, citations, memory) or model (Opus/Sonnet/Haiku) in a file; questions about prompt caching / cache hit rate in an Anthropic SDK project.
SKIP: file imports `openai`/other-provider SDK, filename like `*-openai.py`/`*-generic.py`, provider-neutral code, general programming/ML.
- init: Initialize a new CLAUDE.md file with codebase documentation
- review: Review a pull request
- security-review: Complete a security review of the pending changes on the current branch

**Spec: ✅ All requirements met.**

Every spec item is implemented. Names, signatures, behaviors, and the exact commit message topic all match.

---

**Quality**

**Strengths:**
- Atomicity is correct — `os.CreateTemp(filepath.Dir(path), ...)` places the temp in the same directory, ensuring `os.Rename` is same-device and truly atomic.
- Every error branch in `Add` closes and removes the temp file before returning — no leaks.
- `Load` defers `f.Close()` and checks `scanner.Err()` after the loop.
- `mergeAndSort` pre-allocates both the map and the output slice.
- All four tests use `t.TempDir()` — fully independent.
- No new third-party deps — only the existing `api` package.
- Package doc is accurate and thorough (covers format, first-run semantics, and concurrent-writer caveat).

**Issues:**

1. **`Load` returns `nil` on ENOENT, not `[]string{}`** — per spec this is `(nil, nil)`, which is correct. `TestLoadMissingFileReturnsEmpty` checks `len(got) != 0`, which passes for `nil`, so the test is fine. No defect, just noting the spec and code agree.

2. **`TestPathHonorsUserConfigDir` does not control `XDG_CONFIG_HOME`** — the test calls the real `os.UserConfigDir()`. If the CI environment has no home dir this will fail. The test only validates structural properties (absolute, correct basename/parent), not the actual root, so it is reasonably robust but cannot be made hermetic without `t.Setenv("XDG_CONFIG_HOME", t.TempDir())`. Minor gap — spec did not require it, but worth flagging.

3. **Missing dedup test** — no test verifies that `Add`ing the same address twice results in exactly one entry. `mergeAndSort` handles it correctly, but the behavior is untested.

4. **`w.WriteString` + `w.WriteByte` per line** — minor style: `fmt.Fprintln(w, addr)` or a single `w.WriteString(addr+"\n")` would be cleaner; the two-call pattern is fine but slightly verbose.

**Assessment:** Solid implementation. The only meaningful gap is the missing idempotency/dedup test; everything else is correct. The `TestPathHonorsUserConfigDir` hermetic concern is low-risk but easy to harden.
