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.
npx agentmods add instructions/provartesting/provardx-cli/claude-mdgit clone --depth 1 https://github.com/ProvarTesting/provardx-cliWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.01641 | $0.01641 |
| Opus 5 | $0.00821 | $0.00821 |
| Sonnet 5 | $0.00328 | $0.00328 |
| Haiku 4.5 | $0.00164 | $0.00164 |
Grade A, and why
provardx-cli CLAUDE.md scanned grade A with 1 finding 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 yesterday.
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.
Runs shell commandslowCapability
Expected in a hook, worth knowing in a rule or an instructions file.
- Never construct shell commands from user input; use `spawnSync` with an args array How it starts

Documentation Requirements
Every PR that adds, modifies, or removes an MCP tool must update documentation. The full set of places to update:
| What changed | Where to update |
|---|---|
| New MCP tool | docs/mcp.md (add tool entry with schema + example), docs/mcp-pilot-guide.md (add evaluation scenario if user-facing), README.md (update tool count if referenced) |
| Modified tool description / parameters / errors | docs/mcp.md (update the relevant tool section) |
| Removed tool | docs/mcp.md, docs/mcp-pilot-guide.md, README.md |
| New error code or suggestion field | docs/mcp.md (Troubleshooting or Error Codes section) |
| Security model change (path policy, license, transport) | docs/mcp.md (Security Model section), docs/mcp-pilot-guide.md (Security Model section) |
| New NitroX tool or schema rule | docs/mcp.md (NitroX section), docs/mcp-pilot-guide.md (Scenario 7) |
| Smoke test count change | Update TOTAL_EXPECTED in scripts/mcp-smoke.cjs |
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.
