init

init is a skill for Claude Code from rvdbreemen/adr-kit. It costs 27 tokens per session (633 once invoked), scanned A, original, MIT.

A project setup workflow for ADR Kit, a system that records important architecture decisions and why they were made. It audits the workspace, proposes initial decision records, and adds a commit check.

In plain words
What is it for?
Use it to start ADR Kit in a project, review possible legacy decisions, create proposed ADRs, configure the model backend, and install the pre-commit gate.
Why use it?
It removes the need to discover old decisions, draft records, and configure the project gate by hand. It also makes the evidence and confirmation needed for each proposed decision explicit.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

init scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Initialize ADR Kit (the adopt mode of setup)

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

Invoke explicitly with $adr-kit:init when needed. Resolve <plugin-root> from this installed skill, and <python> to the first of python3, python or, on Windows, py -3 that runs Python 3.10 or newer. Use only bundled, local ADR Kit tools and follow this canonical workflow:

  1. Run the setup workflow, preview legacy ADR migration, and audit the workspace.
  2. Create selected reconstruction candidates as Proposed and present them in small batches.
  3. Use a compact confirmation grill only when the chosen decision, rationale, alternatives, and consequences have direct cited evidence; otherwise use the full grill and confirm each ADR separately.
  4. Install the ADR Kit-owned pre-commit gate, then state plainly that the declarative gate is free and always on while the LLM pass is on by default and costs one model call per llm_judge: true ADR on every commit touching its scope, linear in their number and nothing at all until an author opts one in.
  5. Record the host backend with adr-judge --set-backend host --host-client <this client's id> rather than by writing JSON (the host model is the only backend, ADR-036; operators can override per run with ADR_KIT_LLM_CMD), never prompt for or store an API key, and add docs/adr/.adr-kit.local.json to .gitignore.
  6. Ask the user about the LLM layers, one at a time, showing each layer's current value from <python> <plugin-root>/bin/adr-settings --adr-dir docs/adr: keep it on (the default and the recommendation) or turn it off for this machine. The layers are the per-commit judge pass (judge.llm_enabled; can block a commit; one model call per in-scope llm_judge: true ADR), the missing-decision nudge (suggest.enabled; never blocks) and the guardian's LLM tier (guardian.llm_enabled; asks before each run). All three run on this client's own model; no API key is involved. Apply each 'off' with <python> <plugin-root>/bin/adr-settings --adr-dir docs/adr --set <switch>=false --local, never change a value the user did not answer, and record the answer, also when everything stays on, with --set llm.confirmed=<YYYY-MM-DD> --local (ADR-049).
  7. Finish with adr-doctor --fix-index docs/adr/.

Do not contact another model or mutate user-owned instructions.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

init is a skill published in the GitHub repository rvdbreemen/adr-kit (13 stars, last pushed yesterday), licensed MIT. It adds 27 tokens to every session and 633 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
