Init

Init is a skill for Claude Code from rsts-dev/claude-buddy-marketplace. It costs 103 tokens per session (746 once invoked), scanned A, original, MIT.

A setup tool for adding a checked-in AI layer to an existing code repository. It creates project rules, on-demand context notes, and a starter configuration for Jira, Confluence, and GitHub.

In plain words
What is it for?
Use it to prepare an existing repository for AI-assisted development and to create shared agent rules and tool configuration.
Why use it?
It gives coding agents documented, code-backed guidance about an unfamiliar project without requiring you to write all the instructions yourself.

    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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 8d 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 — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Init

Turn an existing (brownfield) repository into an AI-native one by checking the AI layer into source control: rules (CLAUDE.md), on-demand context modules (.claude/context/), and tool configuration (.mcp.json). Init does not reinvent codebase analysis — it delegates the foundation to buddy and layers the AI-native artifacts on top.

Customization

Before executing, check ~/.claude/LIFEOS/USER/CUSTOMIZATIONS/SKILLS/Init/PREFERENCES.md. If present, load and apply it; otherwise use defaults.

Prerequisites

  1. buddy plugin installed (buddy requires LifeOS). LifeOS marker: test -f ~/.claude/LIFEOS/VERSION. If missing: "LifeOS is required. Run /setup:lifeos, then install the buddy plugin (/plugin install buddy@claude-buddy-marketplace)."
  2. Run inside a git repository with real code (brownfield). For an empty repo, Init falls back to structured questions.
  3. MCP (recommended): Atlassian (Jira/Confluence) + GitHub servers. Optional at init time; .mcp.json is scaffolded for later.

Workflow Routing

Workflow Trigger File
RunInit Any /sdlc:init invocation Workflows/RunInit.md

What it produces

Artifact Path Owner
Project foundation /directive/foundation.md buddy Foundation (delegated)
Global rules CLAUDE.md (repo root, < 300 lines) Init
Context modules .claude/context/*.md Init
MCP config scaffold .mcp.json Init (if absent)

Core principle

Every rule in CLAUDE.md must trace to something real in the codebase — cite it (file:line). Do not invent aspirational rules the code does not follow. Global rules are only for what applies to basically every task; anything task-specific belongs in a .claude/context/ module, not the global file (context rot is real — keep CLAUDE.md lean).

Examples

Example 1: fresh brownfield init

User: "/sdlc:init"
→ Confirms buddy + LifeOS present
→ Runs /buddy:foundation (detects domain, writes /directive/foundation.md)
→ Analyzes the code, derives a lean CLAUDE.md (< 300 lines, rules cited to file:line)
→ Writes .claude/context/{architecture,testing,...}.md for task-specific detail
→ Scaffolds .mcp.json (Atlassian + GitHub) if not present
→ Presents everything for human review before committing

What ships with it

3 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.

Init is a skill published in the GitHub repository rsts-dev/claude-buddy-marketplace (17 stars, last pushed 17d ago), licensed MIT. It adds 103 tokens to every session and 746 once invoked, about $0.0005 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.
