+# T1 Notes

+- Color `gx doctor` failure lines red so blocked auto-finish rows are visible in long recursive runs.
+- Color doctor success lines green, including `No safety issues detected.` and `Repo is fully safe.`, while keeping non-TTY output unchanged.
+- Add a regression that forces ANSI output and proves doctor renders colors for both failure and success status lines.

+## Why
+
+- `gx doctor` already prints compact actionable statuses, but the success and failure lines all use the same default terminal color and are easy to miss in long recursive runs.
+- Auto-finish failures are the most actionable doctor output, yet they visually blend into the surrounding safe scan output.
+- The CLI needs a deterministic way to emit ANSI colors during automated verification so status-color regressions can be tested.
+
+## What Changes
+
+- Color human-readable `gx doctor` success lines green.
+- Color doctor failure lines red and skip/pending lines yellow.
+- Honor the standard `FORCE_COLOR` environment variable so ANSI output can be verified in tests without changing non-color output defaults.
+
+## Impact
+
+- Affects only the human-readable doctor/status CLI output when ANSI colors are enabled.
+- JSON output and non-color terminals remain unchanged.
+- Main risk: over-coloring could reduce readability, so the change stays scoped to doctor scan/final status lines and auto-finish summary/detail rows.

+## ADDED Requirements
+
+### Requirement: `gx doctor` uses semantic status colors
+When ANSI color output is enabled, the human-readable `gx doctor` workflow SHALL color success lines green, failure lines red, and skip or pending lines yellow.
+
+#### Scenario: safe doctor lines render green
+- **GIVEN** `gx doctor` runs in human-readable mode with ANSI color output enabled
+- **WHEN** the repo scan reports `No safety issues detected.` and doctor reaches `Repo is fully safe.`
+- **THEN** both success lines SHALL be emitted in green
+
+#### Scenario: doctor auto-finish failures render red
+- **GIVEN** `gx doctor` runs in human-readable mode with ANSI color output enabled
+- **AND** the auto-finish sweep reports at least one failed branch result
+- **WHEN** doctor prints the auto-finish summary and failed branch detail
+- **THEN** the failure summary line SHALL be emitted in red
+- **AND** the failed branch detail line SHALL be emitted in red
+
+#### Scenario: doctor skip or pending lines render yellow
+- **GIVEN** `gx doctor` runs in human-readable mode with ANSI color output enabled
+- **WHEN** doctor prints a skipped or pending auto-finish line
+- **THEN** that line SHALL be emitted in yellow

+## 1. Specification
+
+- [x] 1.1 Define the doctor status-color requirement for human-readable output.
+
+## 2. Implementation
+
+- [x] 2.1 Color doctor success/failure/pending lines with semantic ANSI colors when color output is enabled.
+- [x] 2.2 Add a regression that forces ANSI output and checks both red failure lines and green success lines.
+
+## 3. Verification
+
+- [x] 3.1 Run `node --check bin/multiagent-safety.js`.
+- [x] 3.2 Run `node --test --test-name-pattern "doctor" test/install.test.js`.
+- [x] 3.3 Run `openspec validate agent-codex-doctor-status-colors-2026-04-21-15-58 --type change --strict`.
+- [x] 3.4 Run `openspec validate --specs`.
+
+Verification note: `node --check bin/multiagent-safety.js` passed. `node --test --test-name-pattern "doctor" test/install.test.js` passed with 18 doctor-focused tests, including the new forced-color regression. `openspec validate agent-codex-doctor-status-colors-2026-04-21-15-58 --type change --strict` passed, and `openspec validate --specs` returned `No items found to validate.`
+
+## 4. Completion
+
+- [ ] 4.1 Finish the agent branch via PR merge + cleanup (`gx finish --via-pr --wait-for-merge --cleanup` or `bash scripts/agent-branch-finish.sh --branch <agent-branch> --base <base-branch> --via-pr --wait-for-merge --cleanup`).
+- [ ] 4.2 Record PR URL + final `MERGED` state in the completion handoff.
+- [ ] 4.3 Confirm sandbox cleanup (`git worktree list`, `git branch -a`) or capture a `BLOCKED:` handoff if merge/cleanup is pending.
