adr-kit setup

Reply in the language the user writes in; default to English. Keep command output, identifiers, paths, and ADR file content unchanged.

Setting up ADR Kit is one deterministic act (spec R19) with four modes. An empty $ARGUMENTS runs the default register mode below. A mode name routes to the procedure that owns it -- follow that skill file and nothing else; each is a mode of this entry point, not a separate product:

Reject any other argument instead of guessing a mode.

You are running the one-time project setup for the adr-kit plugin (register mode). Your job is to:

1. Write the project's instruction layout with scripts/setup-project.py, which owns every file in it.
2. Leave everything outside its managed markers byte-exact.

This is the lightweight counterpart to /adr-kit:init. Use setup when the user has an existing project, already understands their architecture, and just wants the kit registered. Use init when the user wants the kit to also audit the codebase and propose ADRs.

Backwards compatibility (v0.11 footprint)

A project that ran v0.11 /adr-kit:setup has an inline ## ADR Kit Rules section in CLAUDE.md. This skill detects that footprint and leaves it untouched — telling the user to run /adr-kit:upgrade to migrate to the v0.12 marker-bracketed stub + external guide layout. Do not silently rewrite a v0.11 footprint. The upgrade skill exists for that explicit migration.

Steps

1. Resolve the plugin path.

   ADR_KIT="${ADR_KIT_ROOT:-${CLAUDE_PLUGIN_ROOT}}"
   [ -n "$ADR_KIT" ] || { echo "adr-kit: plugin root not found; set ADR_KIT_ROOT, or update or reinstall the plugin" >&2; exit 1; }

   If empty, abort: the plugin install is broken; tell the user to reinstall via /plugin install adr-kit@rvdbreemen-adr-kit.

2. Check for a v0.11 footprint first. Read CLAUDE.md if it exists. If it carries an inline ## ADR Kit Rules section, stop and tell the user: Detected v0.11 ADR Kit Rules section in CLAUDE.md at line <N>. Run /adr-kit:upgrade to migrate. /adr-kit:setup is leaving the v0.11 footprint untouched. Exit without changes. A v0.11 footprint requires an explicit migration; this command never performs one silently.

3. Run the writer. Do not hand-write the instruction block or the guide. scripts/setup-project.py owns the layout, and it is the only thing that knows all of it: CLAUDE.md, AGENTS.md, .github/copilot-instructions.md and .adr-kit/ADR-guide.md. Prose in this skill describing an older layout is how the three clients drifted apart in the first place -- Codex and Copilot delegated here while this file still wrote a guide under .claude/ and a stub block that scripts/project_setup.py classifies as legacy.

   Preview first, then apply:

   python3 "$ADR_KIT/scripts/setup-project.py" --client claude-code-cli --project-root . --dry-run
   python3 "$ADR_KIT/scripts/setup-project.py" --client claude-code-cli --project-root .

   The command is idempotent: re-running it on a current project changes nothing. It writes only inside its managed markers, so user content around them stays byte-exact, and it never touches .adr-kit/ADR-guide.local.md.

   --client also accepts codex-cli and github-copilot-cli, and --clients takes a comma-separated list when a project uses more than one.

4. Report what it did. The command prints one line per change. Relay them, and say plainly when there was nothing to do -- a no-op is the expected outcome of a second run, not a failure.

Constraints

• Two coordinated writes. v0.12 setup writes both the stub AND the guide file. Either-or is incomplete.
• Never silently migrate v0.11. A v0.11 footprint requires explicit /adr-kit:upgrade. Leave v0.11 alone here.
• Idempotent. Re-running on a v0.12 project where everything is current is a no-op.
• Read before write. Preview with --dry-run before applying; the writer reads every file it touches.
• Preserve surrounding content. Only the marker-bracketed stub and the guide file may be touched. Everything else stays byte-exact.
• No em dashes in any text the skill writes (per adr-kit style).

When the user is in the wrong directory

If pwd lacks all of CLAUDE.md, .git/, and a recognisable project manifest (package.json, pyproject.toml, Cargo.toml, platformio.ini, etc.), stop and ask: I do not see a project root here (no CLAUDE.md, no .git, no manifest). Confirm you want to set up adr-kit in <pwd>? Do not silently create files in unexpected locations.

Cross-references

• /adr-kit:setup adopt (alias /adr-kit:init) — full bootstrap including audit and hook installation.
• /adr-kit:setup upgrade (alias /adr-kit:upgrade) — migrate v0.11 → v0.12 footprint without re-auditing.
• /adr-kit:setup hooks (alias /adr-kit:install-hooks) — install the pre-commit hook independently.

Step 4c — The signer: propose, never assume

Every lifecycle command writes a Status History entry naming who decided, and it refuses to sign on the user's behalf. That refusal is right, and it should not be the user's first experience of the tool.

python3 "$ADR_KIT/bin/adr" signer --suggest --adr-dir docs/adr

Read-only: it finds candidates and writes nothing. It looks at the signed-in GitHub account (gh api user, when the CLI is available) and at git config user.name, ranks them, and shows each with its source — a proposal the user cannot trace is one they cannot judge, and this value lands in an immutable history.

• Candidates found — show them and ask which to adopt, or let the user type a different name. Then write it: python3 "$ADR_KIT/bin/adr" signer --set "User: <chosen>".
• Already configured — say so and move on. Do not overwrite it.
• Nothing found — the GitHub CLI is absent or signed out and git names nobody usable. Ask for the name outright rather than guessing.

Bot and CI identities are deliberately not offered. github-actions[bot], runner, a bare user: those are configured values that name a machine, and R8 asks for evidence of which human accepted a decision.

The value is machine-local by design (docs/adr/.adr-kit.local.json, gitignored) because writing one person's name into the tracked config would sign every teammate's acceptances. Each machine, container and CI runner needs its own.
