Combined spec + code-quality review of Task 15 (wire picker into cmd diff) in worktree `/Users/steve.briggs/projects/operations/.claude/worktrees/birdseye`.

Diff: `git diff b9ac21b..894eb9c -- apps/birdseye/cmd/diff.go`

## Spec — What Was Requested

In `apps/birdseye/cmd/diff.go`:

1. Replace the 0-args branch in `runDiff` from `return fmt.Errorf("%w: interactive mode not yet implemented...")` to:
   ```go
   if len(args) == 0 {
       return runInteractive(ctx, cmd, g, o)
   }
   ```

2. Add `runInteractive(ctx, cmd, g, o) error` that:
   - Returns `ErrUsage` if `!isTTY(cmd.OutOrStdout())`
   - Builds client, disk cache, registry
   - Creates picker via `tui.NewPicker(&tui.Deps{Client: cli, Reg: reg})`
   - Runs `tea.NewProgram(p, tea.WithAltScreen(), tea.WithContext(ctx))` and waits
   - Reads `p.Bytes()` — if either nil, return nil (user quit)
   - Extracts both archives (errors wrap `ErrArchive`)
   - Calls `diff.Textual` + `tui.RunBrowser`

3. Import `tea "github.com/charmbracelet/bubbletea"` merged into existing block.

Commit message exact: `feat(birdseye): wire picker -> browser for no-args diff`.

## Quality Focus

- Two-stage runner correctness:
  - Stage 1 runs to completion before Stage 2
  - Stage 2 only runs if Bytes returned non-nil pair
- Error handling: archive errors wrap ErrArchive; ctx-derived errors flow through naturally
- Test coverage: no new tests required since the no-args path needs a TTY
- Import grouping: `tea` placed correctly with other third-party imports
- Resource cleanup: any leaked file descriptors, goroutines from the picker?
- Style consistency with the rest of `diff.go`

## Report Format

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

- 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

- superpowers:executing-plans: Use when you have a written implementation plan to execute in a separate session with review checkpoints
- superpowers:verification-before-completion: Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always

- 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 five spec requirements are met exactly as described.

**Quality:**

**Strengths:**
- Two-stage runner is correctly sequenced: `prog.Run()` blocks until picker exits, `p.Bytes()` is only called after, Stage 2 only runs when both byte slices are non-nil.
- Archive errors correctly wrap `ErrArchive` with `%w` (consistent with the non-interactive path).
- `tea` import is placed correctly — in the third-party group between `bubbletea` and `cobra`, maintaining the stdlib / third-party / internal block structure.
- `isTTY` guard placed first, matching the spirit of fail-fast.
- Nil-pair early return is comment-explained and clean.
- Variable naming (`modA`/`modB` for extracted maps) matches the non-interactive path naming.

**Issues:**

1. **`o` (diffOpts) is accepted but never used.** `runInteractive` ignores `o.Plain`, `o.Semantic`, and potentially other future opts. If the user passed `--plain` with no args, they'd get the interactive TTY check instead of a usage error. That's arguably intentional (plain is for the 3-arg path), but the parameter should either be dropped or have a comment acknowledging it's reserved for future use (semantic diff, Task 17).

2. **Client constructed twice risk.** `runInteractive` duplicates the `client.New(...)`, `registry.NewDiskCache(...)`, `registry.New(...)` setup verbatim from `runDiff`. Not a correctness issue now, but a latent maintenance hazard — if the non-interactive path changes (e.g., auth, retry policy), this fork won't automatically follow. A small private helper `buildRegistry(g, o)` would eliminate the duplication.

3. **Picker resource leak on `prog.Run()` error.** If `prog.Run()` returns an error, the picker's internal goroutines/channels are torn down by BubbleTea's own cleanup, so this is fine. No leak.

4. **`prog.Run()` return value discarded.** The first return value of `prog.Run()` is `(tea.Model, error)`. The model is discarded with `_`, which is correct here since state is read directly from `p.Bytes()` — no issue.

5. **Commit message matches spec exactly.** ✅

**Assessment:** Functionally correct and spec-complete. The only real quality concern worth flagging is the duplicated client/registry construction — not a bug, but it will need consolidation as the codebase grows. The unused `o` parameter is minor but worth a comment.
