Combined spec + code-quality review of Task 4 (ValidArgsFunction for diff + versions) in worktree `/Users/steve.briggs/projects/operations/.claude/worktrees/birdseye`.

Diff: `git diff 51a2c0e..4d747fc -- apps/birdseye/cmd/`

## Spec — What Was Requested

1. `cmd/diff.go` `newDiffCmd`: add `ValidArgsFunction` that:
   - Returns `nil, ShellCompDirectiveNoFileComp` when `len(args) > 0`
   - Otherwise returns `known.Load(resolveKnownPath(o.KnownModulesFile)), ShellCompDirectiveNoFileComp`

2. `cmd/versions.go` `newVersionsCmd`: add a hidden `--known-modules-file` flag (local `knownModulesFile` var, NOT on a struct) plus the same `ValidArgsFunction`. Import `internal/known`.

3. New tests:
   - `TestDiffValidArgsFunctionLoadsCache` (diff_test.go) — `__complete` pseudo-command, asserts cache entries appear in output
   - `TestVersionsValidArgsFunctionLoadsCache` (versions_test.go) — same shape
   - `TestVersionsDoesNotAddToKnown` (versions_test.go) — runs versions, asserts known-modules file NOT created

Commit message exact: `feat(birdseye): shell completion for diff and versions from known-modules cache`.

## Quality Focus

- `if len(args) > 0` guard correctly suppresses suggestions for non-first positional args (versions on the diff command, etc.)?
- Both functions return `ShellCompDirectiveNoFileComp` to suppress filename fallback?
- `versions` does NOT call `known.Add` anywhere (intentional asymmetry — only reads cache, never writes)?
- `versions`'s local `knownModulesFile` variable is correctly closed over by the ValidArgsFunction (closure capture, not value capture)?
- No test pollution: tests use `t.TempDir()` for the cache file?

## Report Format

**Spec:** ✅ / ❌
**Quality:** Strengths / Issues / Assessment

Be terse.

- 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.

**Spec: ✅ All 5 items implemented**

1. `diff.go` `ValidArgsFunction` — `len(args) > 0` guard + `known.Load(resolveKnownPath(...))` + `ShellCompDirectiveNoFileComp`. ✅
2. `versions.go` hidden `--known-modules-file` flag on local `knownModulesFile` var (not a struct) + same `ValidArgsFunction` shape + `known` imported. ✅
3. `TestDiffValidArgsFunctionLoadsCache` — `__complete` invocation, asserts both cache entries in output. ✅
4. `TestVersionsValidArgsFunctionLoadsCache` — same shape for versions. ✅
5. `TestVersionsDoesNotAddToKnown` — runs `versions`, asserts known-modules file not created. ✅
6. Commit message matches spec exactly. (Not verifiable from diff, but that's on the committer.)

**Quality:**

Strengths:
- Guard `len(args) > 0` is correct — suppresses completion after the first positional arg, which is the right behavior for both commands (each takes exactly one module argument).
- Both functions consistently return `ShellCompDirectiveNoFileComp` in all branches — no filename fallback leaks.
- `versions` never calls `known.Add`; the asymmetry is clean and intentional.
- Closure capture is correct: `knownModulesFile` is a `string` declared in the enclosing function scope, and the closure captures the variable (pointer-to-string), not a snapshot of its value at declaration time. Since it's only mutated by flag parsing (before any completion call), this is safe.
- All three tests use `t.TempDir()` — no test pollution.
- `TestVersionsDoesNotAddToKnown` hits a real HTTP server (via `httptest`) to exercise the full run path, not just a stub — solid coverage of the "no side effect" guarantee.

Issues: None significant. One minor observation: `known.Load` errors are silently discarded (`suggestions, _ := ...`) in both ValidArgsFunctions. This is acceptable for completion — a broken cache should degrade gracefully to no suggestions rather than blocking the shell — but it's worth noting the intentional swallow.

Assessment: Implementation is correct, idiomatic, and well-tested. No rework needed.
