claude-code-integration

A set of instructions that connects Claude Code to Specsmith governance. Claude Code is an AI coding assistant that can edit and inspect software projects.

In plain words
What is it for?
Use it to configure Claude Code with a project instruction file or governance connection, run audits and preflight checks, and manage approved work items.
Why use it?
It gives Claude Code a required session process, including permission checks before edits, periodic checkpoints, and saving the session at the end.

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

claude-code-integration 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.

What it actually says

Claude Code — specsmith Governance Integration

One-time setup

specsmith integrate claude-code   # generates CLAUDE.md in project root

For MCP server (structured tool calls without shell roundtrips), add to .mcp.json:

{
  "mcpServers": {
    "specsmith-governance": {
      "command": "specsmith",
      "args": ["mcp", "serve", "--project-dir", "."]
    }
  }
}

Or run: specsmith mcp install-claude-code

Every Claude Code session — mandatory protocol

  1. Run at session start:
specsmith kill-session  # idempotent; safe when no processes exist
specsmith audit --project-dir .
specsmith sync  --project-dir .
specsmith checkpoint --project-dir .
  1. Output the checkpoint block verbatim before any other response.
  2. Before every code change: specsmith preflight "<intent>" --json
    • decision == "accepted" → proceed with work_item_id in scope
    • decision == "needs_clarification" → surface instruction to user first
  3. Every 8–10 turns: specsmith checkpoint (output verbatim)
  4. Session end: specsmith save && specsmith kill-session

Via MCP (preferred when configured)

Claude can call governance_preflight, governance_audit, governance_checkpoint, governance_req_list, governance_phase, and governance_trace_seal as native tools.

Key files

  • CLAUDE.md — project-level governance instructions (read by Claude automatically)
  • .mcp.json — MCP server config (project root or ~/.claude/mcp.json for global)
  • .agents/skills/ — skill files auto-discovered by Claude Code 3.x+

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.

claude-code-integration is a skill published in the GitHub repository layer1labs/specsmith (7 stars, last pushed 29d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 409 tokens. 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.
