Address three findings from the final whole-branch code review of birdseye in worktree `/Users/steve.briggs/projects/operations/.claude/worktrees/birdseye`.

## Fix 1: Wire up `CROW_URL` env var

The flag `--crow-url` advertises `(env CROW_URL)` in its help text and the README documents the env var, but nothing reads it. The sibling app `apps/crowctl` already uses `cli.EnvVars("CROW_URL")` so this is the established convention.

In `apps/birdseye/cmd/root.go`, modify `NewRootCmd` so the default value of `--crow-url` honors `os.Getenv("CROW_URL")` first, then falls back to `defaultCrowURL`. Concretely:

Add `"os"` to imports if absent. Change the `defaultCrowURL` registration:

Before:
```go
root.PersistentFlags().StringVar(&g.CrowURL, "crow-url", defaultCrowURL, "Crow base URL (env CROW_URL)")
```

After:
```go
crowURL := defaultCrowURL
if v := os.Getenv("CROW_URL"); v != "" {
    crowURL = v
}
root.PersistentFlags().StringVar(&g.CrowURL, "crow-url", crowURL, "Crow base URL (env CROW_URL)")
```

Add a test in `apps/birdseye/cmd/root_test.go`:

```go
func TestNewRootCmdRespectsCrowURLEnv(t *testing.T) {
	t.Setenv("CROW_URL", "https://override.example/crow")
	root := NewRootCmd()
	if got, _ := root.PersistentFlags().GetString("crow-url"); got != "https://override.example/crow" {
		t.Errorf("crow-url default = %q, want override from env", got)
	}
}
```

## Fix 2: Delete dead code in Picker

In `apps/birdseye/internal/tui/picker.go`:

a) Delete `func (p *Picker) SetBrowser(b *Browser)` entirely. Two-stage handoff is done via `Bytes()` + a separate `tui.RunBrowser` call from cmd; SetBrowser is never invoked in production.

b) Remove `browser *Browser` field from the `Picker` struct.

c) Remove the `WindowSizeMsg` resize-forwarding to `p.browser` (the block that says `if p.browser != nil { p.browser.SetSize(...) }`). Just keep the width/height storage.

d) Remove the `case StateBrowser:` branch in `Picker.Update` and `Picker.View` — that state is never reachable.

e) `StateBrowser` is still referenced as an enum value (it's in the const block) — KEEP the enum value for clarity. Only delete the dead handling code in Update/View.

After these changes, `Picker` no longer has a `browser` field. The state machine is: AskModule → Loading → AskVersionA → AskVersionB → Loading → (Quit) on pairLoadedMsg.

Verify all picker tests still pass.

## Fix 3: Thread cobra root context into Picker

The picker's `loadVersionsCmd` and `loadPairCmd` both use `context.Background()` instead of the cobra root context, breaking `--timeout` and SIGTERM cancellation.

Changes:

a) Add a `ctx context.Context` field to the `Picker` struct.

b) Change `NewPicker(deps *Deps) *Picker` to `NewPicker(ctx context.Context, deps *Deps) *Picker`. Store the context on the struct.

c) In `loadVersionsCmd`, replace `context.Background()` with `p.ctx`. Same for `loadPairCmd`.

d) In `apps/birdseye/cmd/diff.go` `runInteractive`, change `tui.NewPicker(&tui.Deps{...})` to `tui.NewPicker(ctx, &tui.Deps{...})`.

e) Update the picker tests in `apps/birdseye/internal/tui/picker_test.go` — replace `NewPicker(nil)` with `NewPicker(context.Background(), nil)`. Add `"context"` to imports.

## Verify

After ALL three fixes:

```bash
cd /Users/steve.briggs/projects/operations/.claude/worktrees/birdseye/apps/birdseye && go test -race ./... -v && go vet ./... && go build ./...
```

All tests must pass. `go vet` clean. Build succeeds.

Then smoke-test the binary still launches:

```bash
cd /Users/steve.briggs/projects/operations/.claude/worktrees/birdseye/apps/birdseye && ./bin/birdseye --help 2>&1 | head -30
```

Output should mention `--crow-url` and `(env CROW_URL)`.

Run with env override:

```bash
cd /Users/steve.briggs/projects/operations/.claude/worktrees/birdseye/apps/birdseye && CROW_URL=https://test.example ./bin/birdseye diff foo/bar/aws 1.0.0 2.0.0 --plain 2>&1 | head -5
```

Should mention `https://test.example` in error output (since we can't reach it), confirming the env was honored.

## Commit

Single commit covering all three fixes:

```bash
cd /Users/steve.briggs/projects/operations/.claude/worktrees/birdseye && git add apps/birdseye/cmd/root.go apps/birdseye/cmd/root_test.go apps/birdseye/cmd/diff.go apps/birdseye/internal/tui/picker.go apps/birdseye/internal/tui/picker_test.go && git commit -m "fix(birdseye): wire CROW_URL env, drop dead picker handoff, thread ctx through TUI"
```

- 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:writing-plans: Use when you have a spec or requirements for a multi-step task, before touching code

- 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

Good. I have all the context I need. Now let me apply the three fixes.

**Fix 1: Wire up `CROW_URL` env var in root.go**


Edit

import (
	"time"

	"github.com/spf13/cobra"
)

import (
	"os"
	"time"

	"github.com/spf13/cobra"
)


The file /Users/steve.briggs/projects/operations/.claude/worktrees/birdseye/apps/birdseye/cmd/root.go has been updated successfully. (file state is current in your context — no need to Read it back)


root.PersistentFlags().StringVar(&g.CrowURL, "crow-url", defaultCrowURL, "Crow base URL (env CROW_URL)")

	crowURL := defaultCrowURL
	if v := os.Getenv("CROW_URL"); v != "" {
		crowURL = v
	}
	root.PersistentFlags().StringVar(&g.CrowURL, "crow-url", crowURL, "Crow base URL (env CROW_URL)")


Now add the test for `CROW_URL` env var. Note: the existing `TestNewRootCmdDefaults` assumes no env var is set, which is fine since `t.Setenv` restores the env after the test.


func TestNewRootCmdDefaults(t *testing.T) {
	root := NewRootCmd()
	if got, _ := root.PersistentFlags().GetString("crow-url"); got != "https://crow.infrastructure.immuta.io" {
		t.Errorf("crow-url default = %q", got)
	}
}

func TestNewRootCmdDefaults(t *testing.T) {
	root := NewRootCmd()
	if got, _ := root.PersistentFlags().GetString("crow-url"); got != "https://crow.infrastructure.immuta.io" {
		t.Errorf("crow-url default = %q", got)
	}
}

func TestNewRootCmdRespectsCrowURLEnv(t *testing.T) {
	t.Setenv("CROW_URL", "https://override.example/crow")
	root := NewRootCmd()
	if got, _ := root.PersistentFlags().GetString("crow-url"); got != "https://override.example/crow" {
		t.Errorf("crow-url default = %q, want override from env", got)
	}
}


The file /Users/steve.briggs/projects/operations/.claude/worktrees/birdseye/apps/birdseye/cmd/root_test.go has been updated successfully. (file state is current in your context — no need to Read it back)


**Fix 2: Delete dead code in Picker**

Now I'll remove the dead code from picker.go: `SetBrowser`, `browser` field, browser-forwarding in `WindowSizeMsg`, `StateBrowser` branch in `Update` and `View`.


// Picker is a single bubbletea Model whose internal state enum drives
// which sub-widget is rendered.
type Picker struct {
	deps       *Deps
	state      PickerState
	input      textinput.Model
	moduleID   api.ModuleIdentifier
	versionsA  list.Model
	versionsB  list.Model
	chosenA    string
	chosenB    string
	spinner    spinner.Model
	browser    *Browser
	width      int
	height     int
	errMessage string
	pairA      []byte
	pairB      []byte
}

// Picker is a single bubbletea Model whose internal state enum drives
// which sub-widget is rendered.
type Picker struct {
	deps       *Deps
	state      PickerState
	input      textinput.Model
	moduleID   api.ModuleIdentifier
	versionsA  list.Model
	versionsB  list.Model
	chosenA    string
	chosenB    string
	spinner    spinner.Model
	width      int
	height     int
	errMessage string
	pairA      []byte
	pairB      []byte
}


The file /Users/steve.briggs/projects/operations/.claude/worktrees/birdseye/apps/birdseye/internal/tui/picker.go has been updated successfully. (file state is current in your context — no need to Read it back)


// SetBrowser hands a pre-built Browser to the picker. Used by the cmd
// integration after FetchPair completes (the cmd does the extract+diff
// step and supplies the resulting browser here).
func (p *Picker) SetBrowser(b *Browser) {
	p.browser = b
	if p.width > 0 {
		b.SetSize(p.width, p.height)
	}
	p.state = StateBrowser
}

func (p *Picker) Init() tea.Cmd { return textinput.Blink }

func (p *Picker) Init() tea.Cmd { return textinput.Blink }


Now remove the `WindowSizeMsg` browser-forwarding block and the `StateBrowser` case in `Update`:


	switch msg := msg.(type) {
	case tea.WindowSizeMsg:
		p.width, p.height = msg.Width, msg.Height
		if p.browser != nil {
			p.browser.SetSize(msg.Width, msg.Height)
		}
		return p, nil
	case tea.KeyMsg:

	switch msg := msg.(type) {
	case tea.WindowSizeMsg:
		p.width, p.height = msg.Width, msg.Height
		return p, nil
	case tea.KeyMsg:


Now remove the `StateBrowser` case in `Update`:


	case StateLoading:
		return p.updateLoading(msg)
	case StateBrowser:
		if p.browser == nil {
			return p, tea.Quit
		}
		m, cmd := p.browser.Update(msg)
		p.browser = m.(*Browser)
		return p, cmd
	}
	return p, nil
}

	case StateLoading:
		return p.updateLoading(msg)
	}
	return p, nil
}


Now remove the `StateBrowser` case in `View`:


	case StateAskVersionB:
		return p.versionsB.View()
	case StateBrowser:
		if p.browser != nil {
			return p.browser.View()
		}
	case StateError:

	case StateAskVersionB:
		return p.versionsB.View()
	case StateError:


**Fix 3: Thread cobra root context into Picker**

Now add `ctx` field to `Picker`, update `NewPicker` signature, replace `context.Background()` calls:


// Picker is a single bubbletea Model whose internal state enum drives
// which sub-widget is rendered.
type Picker struct {
	deps       *Deps
	state      PickerState
	input      textinput.Model
	moduleID   api.ModuleIdentifier
	versionsA  list.Model
	versionsB  list.Model
	chosenA    string
	chosenB    string
	spinner    spinner.Model
	width      int
	height     int
	errMessage string
	pairA      []byte
	pairB      []byte
}

// Picker is a single bubbletea Model whose internal state enum drives
// which sub-widget is rendered.
type Picker struct {
	ctx        context.Context
	deps       *Deps
	state      PickerState
	input      textinput.Model
	moduleID   api.ModuleIdentifier
	versionsA  list.Model
	versionsB  list.Model
	chosenA    string
	chosenB    string
	spinner    spinner.Model
	width      int
	height     int
	errMessage string
	pairA      []byte
	pairB      []byte
}


// NewPicker constructs a picker. deps may be nil for input-only tests
// (no network dispatch occurs in that case).
func NewPicker(deps *Deps) *Picker {
	ti := textinput.New()
	ti.Placeholder = "namespace/name/provider"
	ti.Focus()
	sp := spinner.New()
	sp.Spinner = spinner.Dot
	return &Picker{
		deps:    deps,
		state:   StateAskModule,
		input:   ti,
		spinner: sp,
	}
}

// NewPicker constructs a picker. deps may be nil for input-only tests
// (no network dispatch occurs in that case).
func NewPicker(ctx context.Context, deps *Deps) *Picker {
	ti := textinput.New()
	ti.Placeholder = "namespace/name/provider"
	ti.Focus()
	sp := spinner.New()
	sp.Spinner = spinner.Dot
	return &Picker{
		ctx:     ctx,
		deps:    deps,
		state:   StateAskModule,
		input:   ti,
		spinner: sp,
	}
}


Now replace the two `context.Background()` calls with `p.ctx`:


func (p *Picker) loadVersionsCmd(id api.ModuleIdentifier) tea.Cmd {
	return func() tea.Msg {
		versions, err := p.deps.Client.ListVersions(context.Background(), id)
		return versionsLoadedMsg{versions: versions, err: err}
	}
}

func (p *Picker) loadVersionsCmd(id api.ModuleIdentifier) tea.Cmd {
	return func() tea.Msg {
		versions, err := p.deps.Client.ListVersions(p.ctx, id)
		return versionsLoadedMsg{versions: versions, err: err}
	}
}


func (p *Picker) loadPairCmd(id api.ModuleIdentifier, va, vb string) tea.Cmd {
	return func() tea.Msg {
		a, b, err := p.deps.Reg.FetchPair(context.Background(),
			api.Module{ModuleIdentifier: id, Version: va},
			api.Module{ModuleIdentifier: id, Version: vb})
		return pairLoadedMsg{a: a, b: b, err: err}
	}
}

func (p *Picker) loadPairCmd(id api.ModuleIdentifier, va, vb string) tea.Cmd {
	return func() tea.Msg {
		a, b, err := p.deps.Reg.FetchPair(p.ctx,
			api.Module{ModuleIdentifier: id, Version: va},
			api.Module{ModuleIdentifier: id, Version: vb})
		return pairLoadedMsg{a: a, b: b, err: err}
	}
}


Since `context.Background()` is no longer called directly in picker.go, check if the `context` import is still needed (it is, since `ctx context.Context` is a parameter type):


1	package tui
2
3	import (
4		"context"
5		"fmt"
6		"strings"
7
8		"github.com/charmbracelet/bubbles/list"
9		"github.com/charmbracelet/bubbles/spinner"
10		"github.com/charmbracelet/bubbles/textinput"
11		tea "github.com/charmbracelet/bubbletea"
12
13		"github.com/immuta/operations/apps/birdseye/internal/registry"
14		"github.com/immuta/operations/services/crow/pkg/api"
15		"github.com/immuta/operations/services/crow/pkg/client"
16	)
17
18	// PickerState is the explicit state machine the picker walks.
19	type PickerState int
20


Good, `context` is still imported and used for the `ctx context.Context` parameter type. Now update `diff.go` to pass `ctx` to `NewPicker`:


	// Stage 1: picker → fetched bytes
	p := tui.NewPicker(&tui.Deps{Client: cli, Reg: reg})

	// Stage 1: picker → fetched bytes
	p := tui.NewPicker(ctx, &tui.Deps{Client: cli, Reg: reg})


The file /Users/steve.briggs/projects/operations/.claude/worktrees/birdseye/apps/birdseye/cmd/diff.go has been updated successfully. (file state is current in your context — no need to Read it back)


Now update `picker_test.go` to use `NewPicker(context.Background(), nil)`:


package tui

import (
	"testing"

	tea "github.com/charmbracelet/bubbletea"
)

package tui

import (
	"context"
	"testing"

	tea "github.com/charmbracelet/bubbletea"
)


The file /Users/steve.briggs/projects/operations/.claude/worktrees/birdseye/apps/birdseye/internal/tui/picker_test.go has been updated successfully. (file state is current in your context — no need to Read it back)


The file /Users/steve.briggs/projects/operations/.claude/worktrees/birdseye/apps/birdseye/internal/tui/picker_test.go has been updated. All occurrences were successfully replaced. (file state is current in your context — no need to Read it back)


Now run the full test suite, vet, and build:


Bash

cd /Users/steve.briggs/projects/operations/.claude/worktrees/birdseye/apps/birdseye && go test -race ./... -v 2>&1

All tests pass. Now run `go vet` and build:


cd /Users/steve.briggs/projects/operations/.claude/worktrees/birdseye/apps/birdseye && go vet ./... && go build -o bin/birdseye ./... && echo "BUILD OK"


Error: Exit code 1
go: cannot write multiple packages to non-directory bin/birdseye


cd /Users/steve.briggs/projects/operations/.claude/worktrees/birdseye/apps/birdseye && go vet ./... && go build -o bin/birdseye . && echo "BUILD OK"


BUILD OK


Now smoke-test the binary:


cd /Users/steve.briggs/projects/operations/.claude/worktrees/birdseye/apps/birdseye && ./bin/birdseye --help 2>&1 | head -30


Diff two versions of a Terraform module hosted in Crow

Usage:
  birdseye [flags]
  birdseye [command]

Available Commands:
  completion  Generate the autocompletion script for the specified shell
  diff        Diff two versions of a Crow module
  help        Help about any command
  versions    List published versions of a Crow module

Flags:
      --crow-url string    Crow base URL (env CROW_URL) (default "https://crow.infrastructure.immuta.io")
  -h, --help               help for birdseye
      --json               emit structured JSON to stdout where supported
      --timeout duration   per-operation HTTP timeout (default 30s)

Use "birdseye [command] --help" for more information about a command.


`--crow-url` shows `(env CROW_URL)`. Now the env override smoke test:


cd /Users/steve.briggs/projects/operations/.claude/worktrees/birdseye/apps/birdseye && CROW_URL=https://test.example ./bin/birdseye diff foo/bar/aws 1.0.0 2.0.0 --plain 2>&1 | head -5


birdseye: Get "https://test.example/v1/modules/foo/bar/aws/2.0.0/download": dial tcp: lookup test.example: no such host


`https://test.example` appears in the error — env override is working. Now commit:


git add apps/birdseye/cmd/root.go apps/birdseye/cmd/root_test.go apps/birdseye/cmd/diff.go apps/birdseye/internal/tui/picker.go apps/birdseye/internal/tui/picker_test.go && git commit -m "$(cat <<'EOF'

[worktree-birdseye 7605503] fix(birdseye): wire CROW_URL env, drop dead picker handoff, thread ctx through TUI
 5 files changed, 24 insertions(+), 34 deletions(-)


All three fixes applied cleanly. Here's the summary:

---

**Status: DONE**

## Fix 1: CROW_URL env var wired up
`apps/birdseye/cmd/root.go` — added `os` import, replaced the bare `defaultCrowURL` default with a two-line env-check block that prefers `CROW_URL` over the compile-time constant. Added `TestNewRootCmdRespectsCrowURLEnv` in `root_test.go` using `t.Setenv` to verify the override.

## Fix 2: Dead picker code deleted
`apps/birdseye/internal/tui/picker.go` — removed: `browser *Browser` field, `SetBrowser` method, the `if p.browser != nil { p.browser.SetSize(...) }` branch in `WindowSizeMsg` handling, and the `StateBrowser` cases in both `Update` and `View`. The `StateBrowser` enum constant itself was preserved in the `const` block. The state machine is now: AskModule → Loading → AskVersionA → AskVersionB → Loading → Quit on pairLoadedMsg.

## Fix 3: cobra context threaded into Picker
`Picker` gained a `ctx context.Context` field. `NewPicker` signature changed to `NewPicker(ctx context.Context, deps *Deps)`. Both `loadVersionsCmd` and `loadPairCmd` now use `p.ctx` instead of `context.Background()`. `diff.go` updated to pass `ctx` at the call site. `picker_test.go` updated with `context` import and `NewPicker(context.Background(), nil)` at all three call sites.

## Verification
- **Tests:** 28 pass, 0 fail, race-clean
- **go vet:** clean
- **Build:** succeeds (`go build -o bin/birdseye .`)
- **--help:** confirms `--crow-url string   Crow base URL (env CROW_URL)`
- **Env override smoke test:** `CROW_URL=https://test.example` correctly appears in the network error: `Get "https://test.example/v1/modules/..."`
- **Commit:** `7605503`
