adopt

adopt is a skill for Claude Code, Codex from ApurvBazari/claude-plugins. It costs 65 tokens per session (3,604 once invoked), scanned A, original, MIT.

A setup tool for bringing existing, manually created Claude tools in a code repository under onboard management. It records their current state without changing those files.

In plain words
What is it for?
Use it to catalog existing Claude tooling and prepare it for management by onboard update commands. It is intended for explicit adoption or for starting an update when management metadata is missing.
Why use it?
It creates the baseline needed for later onboard updates while preserving the tooling you already wrote.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

adopt 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 3d 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.

The opening of the file, as written. The whole thing — 142 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Adopt Skill — Retrofit Foreign Claude Tooling

You are running the onboard adopt skill. It brings a project's pre-existing, hand-crafted Claude tooling under onboard management by synthesizing a baseline — onboard-meta.json (mode:"retrofit") plus snapshots — so /onboard:update can manage it. Adopt never modifies a hand-crafted file. It writes only the baseline; all modernization is deferred to /onboard:update, per-item approved.

This skill may be entered three ways: directly (/onboard:adopt), from /onboard:start's existing-config branch (the Adopt option), or from /onboard:update's missing-meta guard (offer adopt → continue into drift detection). When entered from update, after A6 hand back control to update's drift detection.

Overview

Tell the developer:

Adopting your existing Claude tooling — I'll catalog what you already have, research your codebase to ground the baseline, confirm a few preferences, then show you a full preview before writing anything. I won't touch your hand-crafted files — I only record a baseline so /onboard:update can manage them going forward.

Step 0: Initialize Phase Tracking

Runs first, before Step A1. This wires the durable phase-task list that the rest of the flow transitions for in-session visibility.

First, read the contract: ../start/references/phase-tracking.md (the cross-skill source of truth — start is its worked example). It defines the task subjects, the pending → in_progress → completed (plus deleted) state machine, and the HARD GATE mapping. Follow it verbatim — do not re-derive its rules here. adopt operates on a project that already has hand-crafted tooling and writes its own onboard-meta.json only at the end (Step A6), so the task list here is in-session progress visibility; the durable record lives in the on-disk artifacts the contract describes (the baseline meta + snapshots written at A6).

Create the 6 adopt phase tasks via TaskCreate, all status: "pending", one per ladder phase, using the adopt: subject prefix from the contract's § Other entry points table:

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
