cc — cc-settings management

Three-mode skill: sync keeps the repo current with the Claude Code and Codex CLI upstreams (maintainer task); update refreshes the active Claude Code, Codex, or combined local install (everyone); migrate moves a project's CLAUDE.md into AGENTS.md so every coding agent reads one file.

Mode: sync

Audit cc-settings against the Claude Code changelog and the Codex release notes; identify features to adopt and duplication to remove; stops for approval.

Track both upstreams and keep cc-settings (schemas, config, hooks, agents, docs, the Codex installer surfaces) in sync with new features. Removes anything that duplicates native functionality.

This is run on a weekly cadence. The mechanical parts are scripted; the judgment calls (which features to adopt, what counts as duplication) require human review at the gate.

Before you start

Always run from the cc-settings repo root. If you're not there, ask the user where it is — don't guess.

pwd  # should end in /cc-settings
git status  # tree must be clean before starting

If the tree is dirty, ask the user to commit or stash first. Sync work needs a clean baseline so the diff is reviewable.

Phase 1 — Detect drift

bun run upstream:scan

This compares upstream/claude-code-manifest.json against the live @anthropic-ai/claude-code npm version and upstream/codex-manifest.json against the live @openai/codex npm version. Each upstream has two outcomes:

No drift — manifest matches live. Nothing to sync for that upstream.
Drift detected — capture both versions. Format: manifest=A → live=B.

If neither drifts, tell the user "already in sync at Claude Code v, Codex v" and end. If only one drifts, run the remaining phases for that upstream alone and say so in the plan.

Phase 2 — Fetch the upstream changelog

Fetch the official changelog and extract entries between the manifest version (exclusive) and the live version (inclusive):

WebFetch url: https://raw.githubusercontent.com/anthropics/claude-code/main/CHANGELOG.md
prompt: Extract entries for versions <A+1> through <B> verbatim. List each
        version's bullet points exactly as written.

Do not paraphrase. Quote the upstream bullets verbatim — the user needs to see exactly what was said upstream to validate your categorization.

Codex

Codex publishes release notes per GitHub release, not a changelog file. Stable releases are tagged rust-v<X>; alpha tags and Python SDK tags are not tracked. List the stable versions after the manifest version, then read each release body verbatim:

gh release list -R openai/codex --exclude-pre-releases --limit 20 \
  | grep -E '^[0-9]+\.[0-9]+\.[0-9]+\s' | awk '{print $1}'
gh release view rust-v<X> -R openai/codex --json body --jq '.body'

Phase 3 — Cross-reference cc-settings

For each upstream change, decide which bucket it falls into. Read these files to inform the decision (use parallel tool calls):

Bucket	What to check
Settings keys	`src/schemas/settings.ts` (zod schema, strict — drift fails parse)
Hook events / types	`src/schemas/hooks.ts` (5-arm discriminated union as of v10.3.0)
MCP fields	`src/schemas/mcp.ts` (shared `mcpCommon` for cross-transport fields)
Env vars	`upstream/claude-code-manifest.json` `knownEnvVars`, `docs/settings-reference.md` env table, `config/10-core.json` `env` block
Hook wiring	`config/40-hooks.json`, `src/hooks/`, `src/scripts/`
Statusline	`src/hooks/statusline.ts` (Payload type)
Agent frontmatter	`agents/*.md` (currently uses `tools`, `disallowedTools`, `maxTurns`, `permissionMode`, `effort`, `isolation`, `hooks`, `mcpServers`, `initialPrompt`)
Slash commands	`MANUAL.md` "All Skills" table, `skills/*/SKILL.md` triggers
User-facing docs	`MANUAL.md`, `CLAUDE-FULL.md`, `docs/settings-reference.md`, `docs/hooks-reference.md`

For Codex changes, cross-reference these surfaces instead. There is no zod schema for any of them; upstream/codex-manifest.json knownConfigSurfaces lists what the installer writes or reads so a release note that names one is easy to spot.

Bucket	What to check
Native agents (`agents/*.toml` fields)	`src/lib/codex-native-agents.ts`, `codex/agents/`
Command policy (`rules/*.rules`)	`codex/rules/darkroom.rules`
Plugin manifest and hooks	`plugin.json`, `mcp.json`, `hooks/hooks.json` (installed as `$CODEX_HOME/hooks.json`), `src/lib/codex-runtime-manifests.ts`
`config.toml` keys the installer reads	`src/lib/codex-install-state.ts`, `src/lib/codex-skill-budget.ts`
Skill loading and budgets	`src/lib/lint-skills.ts`, `docs/codex.md` "skill descriptions were shortened"
Bridge (`codex exec`, `codex review`, model pins)	`src/lib/claude-bridge.ts`, `codex-run.ts`, `docs/codex-bridge.md`
User-facing docs	`docs/codex.md`, `codex/AGENTS.append.md`

Bucket each change as one of:

ADOPT — new upstream feature worth taking. List the exact files to edit.
DEDUPE — native feature that now overlaps with cc-settings code. List the files/lines to delete. Look hardest for these — they're the cleanup wins.
DOCS-ONLY — purely a documentation update (e.g. slash command renamed, table needs refresh).
SKIP — not relevant (Windows-only, enterprise-only, fixes a bug we didn't have, etc.). Briefly say why.

Common DEDUPE patterns to look for

cc-settings has historically duplicated upstream work, then deleted it once the upstream version stabilized. Watch for these patterns:

A new built-in hook event subsumes a custom hook script.
A new tool replaces a wrapper we maintain (e.g. native Skill tool replaced our skill-activation.ts in v10.1.0).
A new frontmatter field replaces a script-driven workaround.
A new env var replaces a custom env-var dance.

Phase 4 — Stop. Present the plan.

Write a markdown table to the chat:

## Claude Code v<A> → v<B>, Codex v<C> → v<D> sync plan

### Adopt
| Change | Files | Notes |
|---|---|---|
| ... | ... | ... |

### Dedupe
| Native feature | What to remove | Why redundant |
|---|---|---|

### Docs-only
| Change | File |
|---|---|

### Skip
| Change | Reason |
|---|---|

Then ask the user one question: which rows do they approve?

"Approve all" → continue with everything.
"Approve subset" → user names rows.
"Reject" → end the skill, no edits.

Do not edit before approval.

Phase 5 — Execute approved changes

For approved adoptions, edit the files directly. Schemas first (they're the contract), then config, then docs. Codex adoptions have no schema step: edit the installer surface, then docs/codex.md. For deduptions, delete the orphaned code and any tests that asserted on it.

After each schema edit, also update upstream/claude-code-manifest.json (knownSettingsKeys, knownHookTypes, knownEnvVars) — the scanner uses this as the source of truth.

Phase 6 — Manifest bump + version bump + CHANGELOG

upstream/claude-code-manifest.json
  - claudeCodeVersion: "<B>"
  - lastScan: <today ISO>
  - notes: append one entry summarizing the window (adopted, docs-only, skipped)
upstream/codex-manifest.json
  - codexVersion: "<D>"
  - lastScan: <today ISO>
  - notes: append one entry; add any new surface to knownConfigSurfaces
src/setup.ts
  - VERSION: bump (minor for new features, patch for fixes-only)
CHANGELOG.md
  - Prepend new section: "## [<new-version>] — <today YYYY-MM-DD>"

CHANGELOG entry structure (mirror prior entries — 10.1.0, 10.2.0, 10.2.1, 10.3.0 are good examples):

One-line summary.
Adopted: bullet per feature. State the upstream version, the file(s) touched, and a one-sentence "why this matters".
Deletions / Native-now-redundant: bullet per removed thing. State what replaced it and the upstream version.
Files changed: flat list, one per line.

Phase 7 — Validate

bun run typecheck
bun test
bun run upstream:scan   # should now show "no drift detected" for both upstreams
bun run compose | head  # spot-check that new fields surface in settings.json

If any fail: fix before moving on. Tests must pass.

Phase 8 — Commit + push

git add -A
git commit -m "feat(v<new-version>): sync with Claude Code v<B> and Codex v<D>

<one-paragraph summary>

Adopted:
- ...

Deletions:
- ..."
git push -u origin HEAD
gh pr create --base main --fill

Work on a branch: main rejects direct pushes and requires the org ci-gate workflow, which runs only on a PR. Merge the PR once it passes; darky/review is not required. Use conventional commit prefix feat(v<X.Y.Z>): so the version stands out in git log. Do not push if anything in Phase 7 is failing.

What this mode does NOT do

It does not edit user-installed ~/.claude/settings.json. cc-settings is the source — users get the changes by re-running setup.sh.
It does not run on a schedule. A cron could only bump the version number, never triage the changelog, so bun run upstream:scan is the manual drift detector and this skill is the only sync path.
It does not bump dependencies. That's a separate concern.

Mental model

cc-settings exists in three time zones:

Upstream — what Claude Code and Codex do today. Source: the Claude Code changelog and the Codex GitHub release notes.
Manifest — what cc-settings believes upstream does. Source: upstream/claude-code-manifest.json and upstream/codex-manifest.json.
Implementation — what cc-settings actually wires up. Source: schemas, config, hooks, agents.

Drift between (1) and (2) means the scanner is stale. Drift between (2) and (3) means our schemas accept things our installer never configures, or vice versa — usually fine, but worth flagging.

This mode aligns all three.

Mode: update

Pull the latest cc-settings into the active host. Choose the target before looking for a checkout:

An explicit request for both products selects both.
A standalone Codex session selects codex.
Otherwise select claude.

Never treat ${CODEX_HOME:-$HOME/.codex}/darkroom/source as a checkout. It is a copied, non-git runtime allowlist and must never be pulled.

Phase 1 — Locate the real working repo

Read repo_path from the selected product sentinel first. For both, try the Codex sentinel before the Claude sentinel. Then try known checkout paths. Every candidate must contain .git and have the expected origin.

CODEX_ROOT="${CODEX_HOME:-$HOME/.codex}"
TARGET="codex" # use claude or both according to the host/explicit request above
CODEX_SENTINEL="$CODEX_ROOT/.cc-settings-version"
CLAUDE_SENTINEL="$HOME/.claude/.cc-settings-version"
CODEX_RUNTIME="$CODEX_ROOT/darkroom/source"

candidate_from_sentinel() {
  jq -r '.repo_path // empty' "$1" 2>/dev/null
}

CANDIDATES=()
if [ "$TARGET" = "codex" ] || [ "$TARGET" = "both" ]; then
  CANDIDATES+=("$(candidate_from_sentinel "$CODEX_SENTINEL")")
fi
if [ "$TARGET" = "claude" ] || [ "$TARGET" = "both" ]; then
  CANDIDATES+=("$(candidate_from_sentinel "$CLAUDE_SENTINEL")")
fi
CANDIDATES+=("$CODEX_ROOT/cc-settings" "$HOME/.claude/cc-settings" "$PWD")

CC_REPO=""
for candidate in "${CANDIDATES[@]}"; do
  [ -n "$candidate" ] || continue
  [ "$candidate" != "$CODEX_RUNTIME" ] || continue
  [ -d "$candidate/.git" ] || continue
  ORIGIN=$(git -C "$candidate" remote get-url origin 2>/dev/null) || continue
  NORMALIZED_ORIGIN=$(printf '%s' "$ORIGIN" | sed -E 's/^[[:space:]]+//; s/[[:space:]]+$//; s:/+$::; s:[.]git$::')
  [ "$NORMALIZED_ORIGIN" = "https://github.com/darkroomengineering/cc-settings" ] || continue

# cc — cc-settings management

Three-mode skill: **sync** keeps the repo current with the Claude Code and
Codex CLI upstreams (maintainer task); **update** refreshes the active Claude
Code, Codex, or combined local install (everyone); **migrate** moves a
project's `CLAUDE.md` into `AGENTS.md` so every coding agent reads one file.

## Mode: sync

Audit cc-settings against the Claude Code changelog and the Codex release
notes; identify features to adopt and duplication to remove; stops for approval.

Track both upstreams and keep cc-settings (schemas, config, hooks, agents,
docs, the Codex installer surfaces) in sync with new features. Removes anything
that duplicates native functionality.

This is run on a weekly cadence. The mechanical parts are scripted; the
judgment calls (which features to adopt, what counts as duplication) require
human review at the gate.

### Before you start

Always run from the `cc-settings` repo root. If you're not there, ask the user
where it is — don't guess.

```bash
pwd  # should end in /cc-settings
git status  # tree must be clean before starting
```

If the tree is dirty, ask the user to commit or stash first. Sync work needs a
clean baseline so the diff is reviewable.

### Phase 1 — Detect drift

```bash
bun run upstream:scan
```

This compares `upstream/claude-code-manifest.json` against the live
`@anthropic-ai/claude-code` npm version and `upstream/codex-manifest.json`
against the live `@openai/codex` npm version. Each upstream has two outcomes:

- **No drift** — manifest matches live. Nothing to sync for that upstream.
- **Drift detected** — capture both versions. Format: `manifest=A → live=B`.

If neither drifts, tell the user "already in sync at Claude Code v<X>, Codex
v<Y>" and end. If only one drifts, run the remaining phases for that upstream
alone and say so in the plan.

### Phase 2 — Fetch the upstream changelog

Fetch the official changelog and extract entries between the manifest version
(exclusive) and the live version (inclusive):

```
WebFetch url: https://raw.githubusercontent.com/anthropics/claude-code/main/CHANGELOG.md
prompt: Extract entries for versions <A+1> through <B> verbatim. List each
        version's bullet points exactly as written.
```

Do not paraphrase. Quote the upstream bullets verbatim — the user needs to see
exactly what was said upstream to validate your categorization.

#### Codex

Codex publishes release notes per GitHub release, not a changelog file. Stable
releases are tagged `rust-v<X>`; alpha tags and Python SDK tags are not
tracked. List the stable versions after the manifest version, then read each
release body verbatim:

```bash
gh release list -R openai/codex --exclude-pre-releases --limit 20 \
  | grep -E '^[0-9]+\.[0-9]+\.[0-9]+\s' | awk '{print $1}'
gh release view rust-v<X> -R openai/codex --json body --jq '.body'
```

### Phase 3 — Cross-reference cc-settings

| Statusline | `src/hooks/statusline.ts` (Payload type) |
| Agent frontmatter | `agents/*.md` (currently uses `tools`, `disallowedTools`, `maxTurns`, `permissionMode`, `effort`, `isolation`, `hooks`, `mcpServers`, `initialPrompt`) |
| Slash commands | `MANUAL.md` "All Skills" table, `skills/*/SKILL.md` triggers |
| User-facing docs | `MANUAL.md`, `CLAUDE-FULL.md`, `docs/settings-reference.md`, `docs/hooks-reference.md` |

For Codex changes, cross-reference these surfaces instead. There is no zod
schema for any of them; `upstream/codex-manifest.json` `knownConfigSurfaces`
lists what the installer writes or reads so a release note that names one is
easy to spot.
