init

init is a skill for Claude Code from Abilityai/abilities. It costs 35 tokens per session (1,745 once invoked), scanned A, original, MIT.

A one-time setup tool for adding a documentation-driven development structure to a project. It creates project guidance, memory files, workflow documents, and testing templates after checking whether the setup already exists.

In plain words
What is it for?
Use it when starting the methodology in a project to create its folders and templates and collect basic project information.
Why use it?
It gives a project a consistent place for requirements, architecture notes, feature flows, and testing guidance. The initial checks help avoid overwriting an existing setup without confirmation.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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 1mo 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 — 184 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Initialize Dev Methodology

ℹ️ First, set expectations: before anything else, print one short line with this skill's version and its most recent change — the top entry of metadata.changelog above — e.g. init vX.Y — recent: <summary>. Then proceed.

Scaffold the documentation-driven development methodology into the current project.

Process

Step 1: Check Existing Setup

Check if the methodology is already initialized:

ls docs/memory/requirements.md 2>/dev/null && echo "EXISTS" || echo "NOT_FOUND"
ls CLAUDE.md 2>/dev/null && echo "EXISTS" || echo "NOT_FOUND"

If files already exist, ask the user if they want to overwrite or skip existing files.

Step 2: Gather Project Information

If $ARGUMENTS is provided, use it as the project name.

Otherwise, ask the user for:

  • Project name (e.g., "My App")
  • Project description (one-line)
  • Repository URL (e.g., https://github.com/org/repo)
  • Backend URL (default: http://localhost:8000)
  • Frontend URL (default: http://localhost:3000)

Step 3: Create Directory Structure

mkdir -p docs/memory/feature-flows
mkdir -p docs/reports
mkdir -p docs/security-reports
mkdir -p testing/phases

Step 4: Scaffold CLAUDE.md

Read the CLAUDE.md template from the plugin:

${CLAUDE_PLUGIN_ROOT}/reference/templates/CLAUDE.md.template

Replace all placeholders with the user's values:

  • {{PROJECT_NAME}} -> project name
  • {{PROJECT_DESCRIPTION}} -> description
  • {{REPO_URL}} -> repository URL
  • {{BACKEND_URL}} -> backend URL
  • {{FRONTEND_URL}} -> frontend URL

Write to CLAUDE.md in the project root.

Step 5: Scaffold Memory Files

Copy each template from the plugin, removing the .template extension:

Source (in plugin) Destination
reference/templates/requirements.md.template docs/memory/requirements.md
reference/templates/architecture.md.template docs/memory/architecture.md
reference/templates/roadmap.md.template docs/memory/roadmap.md
reference/templates/changelog.md.template docs/memory/changelog.md
reference/templates/feature-flows.md.template docs/memory/feature-flows.md
reference/templates/feature-flows/_example-feature.md docs/memory/feature-flows/_example-feature.md

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.
