init

A guided workflow for adding or updating Cladding in a project from an idea, planning document, or existing codebase. It prepares and stages the proposed changes, then waits for the user's approval before applying them.

In plain words
What is it for?
Use it when explicitly initializing, adopting, or refreshing Cladding. It can start from a project idea, a project-relative planning document, or an existing codebase.
Why use it?
It prevents an ordinary project-opening request from being treated as permission to change the project. It also shows what will change before the user confirms it.

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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 31 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Cladding init

Use this workflow only when the user explicitly asks to initialize, adopt, or refresh Cladding. Opening a repository alone is not consent to initialize it.

Required host workflow

If the current user message itself matches APPLY CLADDING XXXXXX, do not call prepare or stage again. Call clad_init once and copy the entire user message, including the APPLY CLADDING prefix, into confirmation.

  1. If a greenfield request has no project intent, ask for one short description.
  2. Call clad_prepare_init with exactly one starting mode:
    • idea with the user's description.
    • document with a project-relative planning-document path.
    • existing for an existing codebase; include an optional adoption goal.
  3. Read the returned prompt and observations. Draft the structured object required by clad_init using the current host model, then call clad_stage_init with the preparation token and that draft. Staging validates the draft and stores only ignored runtime state under .cladding/host/; it does not modify authored project files.
  4. Show plannedChanges, the staged confirmationQuestion, and its one-time approvalChallenge to the user, then stop and wait for a separate reply. The original initialization request is not confirmation.
  5. Only when the user's separate reply exactly matches approvalChallenge, call clad_init with the entire reply verbatim as confirmation—never strip the APPLY CLADDING prefix. Include the draft and token when the host retained them; process-per-turn hosts may omit both because Cladding resolves the exact staged draft from its short-lived machine-local cache. Questions, paraphrases, and generic acknowledgements are not approval.
  6. If nextQuestion is present, show it verbatim and end the assistant turn immediately. Never answer it, infer an answer, or call either clarify tool during the initialization-approval turn. Continue with the Cladding clarify workflow only after a new user message supplies the answer. If no question remains, report that onboarding is complete and that the next step is to author the first feature's spec — its acceptance criteria and the files it will cover — before writing any code; the feature cycle starts there, not with scaffolding.

What this file has done since we first saw it

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 qwerfunch/cladding (14 stars, last pushed 5d ago), licensed MIT. It adds 52 tokens to every session and 739 once invoked, about $0.0003 per session on Opus 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 2026-08-30.
