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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.00290 |
| Opus 5 | $0.00000 | $0.00145 |
| Sonnet 5 | $0.00000 | $0.00058 |
| Haiku 4.5 | $0.00000 | $0.00029 |
Grade A, and why
cursor-integration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Cursor — specsmith Governance Integration
One-time setup
specsmith integrate cursor # generates .cursor/rules/governance.mdc
For MCP in Cursor (Settings → MCP or .cursor/mcp.json):
{
"specsmith-governance": {
"command": "specsmith",
"args": ["mcp", "serve", "--project-dir", "${workspaceFolder}"]
}
}
Every Cursor session — mandatory protocol
- 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 .
- Output the checkpoint block verbatim.
- Before every code change:
specsmith preflight "<intent>" --json - Every 8–10 turns:
specsmith checkpoint(output verbatim) - Session end:
specsmith save && specsmith kill-session

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.

cursor-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 290 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.
