You are re-reviewing the code quality of Task 2 of the birdseye CLI after a fix commit.

## Working Directory

`/Users/steve.briggs/projects/operations/.claude/worktrees/birdseye`

## Diff to Review

```
BASE_SHA: ae477d5
HEAD_SHA: 59cd0b6
```

Run `git diff ae477d5..59cd0b6 -- apps/birdseye/cmd/` in the worktree. Two commits:
- `3b73e14` — original Task 2 (root command + ExitCode)
- `59cd0b6` — fix commit addressing review nits

## Previous Review Concerns

The first quality review flagged:

1. **`g := &GlobalFlags{}` inaccessible to subcommands** — DISPUTED, NOT FIXED. The controller determined this was a false positive: the design uses a shared pointer that subcommand constructors (`newDiffCmd(g)`, `newVersionsCmd(g)`, added in future tasks) close over. Cobra writes into `*g` during flag parsing. **You do NOT need to re-flag this issue.**

2. `DeadlineExceeded` not tested — FIXED in `59cd0b6`
3. `ErrSemantic` doc too narrow — FIXED in `59cd0b6` (now `"semantic diff parse error"` with broader comment)
4. Bare exit-code integers — FIXED in `59cd0b6` (named constants `exitOK`…`exitUserCancelled`)
5. `RunE` lacks explanatory comment — FIXED in `59cd0b6`
6. `TestNewRootCmdDefaults` tests cobra internals (minor) — NOT FIXED (was deferred to when subcommands exist)

## Your Job

Verify that the fixes in `59cd0b6` were applied correctly and didn't break anything. Use the worktree to:

- Read `apps/birdseye/cmd/errors.go` and confirm:
  - Named constants exist (`exitOK = 0`, `exitUsage = 1`, etc.)
  - `ExitCode` uses the named constants in its return statements
  - `ErrSemantic` doc/message is broadened
  - `ErrUsage` and `ErrArchive` got per-sentinel doc comments
- Read `apps/birdseye/cmd/errors_test.go` and confirm:
  - `context.DeadlineExceeded` test case present
  - All 6 cases (or 8 — count them) are valid
- Read `apps/birdseye/cmd/root.go` and confirm:
  - A comment explains the `RunE: cmd.Help()` workaround
  - Otherwise unchanged
- Run `cd /Users/steve.briggs/projects/operations/.claude/worktrees/birdseye/apps/birdseye && go test -race ./cmd/... -v` and confirm all tests pass

## Report Format

**Strengths:** (1-3 bullets, only fixes-related)

**Outstanding issues:**
- Critical: (likely none)
- Important: (worth blocking on)
- Minor: (nice-to-haves)

**Assessment:** APPROVED | NEEDS_CHANGES

- migrate-flux-app: Use when migrating a Flux CD application from the infrastructure/kubernetes/application-deployments repo to the application-deployment repo. Covers copying app folders, updating kustomizations, committing, pushing, and creating merge requests.
- app-infra-generate: Generate an application-infrastructure Terraform module from a YAML spec produced by app-infra-spec. Reads pattern files and a versions manifest to produce main.tf, variables.tf, outputs.tf, overlay guidance, and a triage list.
- app-infra-spec: Structured questionnaire to gather requirements for an application-infrastructure Terraform module. Produces a YAML spec for the app-infra-generate skill.

- superpowers:using-git-worktrees: Use when starting feature work that needs isolation from current workspace or before executing implementation plans - ensures an isolated workspace exists via native tools or git worktree fallback
- 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

text:
All tests pass. Here's the assessment:

**Strengths:**
- Named exit-code constants (`exitOK = 0` through `exitUserCancelled = 130`) are present and cleanly applied throughout `ExitCode` — no bare integers remain.
- `context.DeadlineExceeded` is now tested alongside `context.Canceled` in a dedicated `"context-deadline"` case; the `wrapped-not-found` case validates `errors.Is` chain behavior.
- The `RunE` workaround comment in `root.go` is clear and accurate, explaining both the cobra v1.x stderr-routing issue and that subcommands bypass the handler.

**Outstanding issues:**
- Critical: none
- Important: none
- Minor: The test suite covers 6 of the 7 exit codes (missing explicit cases for `ErrUsage`, `ErrArchive`, and `ErrSemantic` sentinels). `generic` covers the default path, but the three named sentinels above go untested. Low risk given the function is a straight switch, but worth noting for completeness.

**Assessment: APPROVED**

The three fixes were applied correctly and nothing was broken. The minor gap (no test cases for `ErrUsage`/`ErrArchive`/`ErrSemantic`) existed before this commit and is a pre-existing omission rather than a regression — not worth blocking on.
