fakoli-sentinel

fakoli-sentinel is an agent for Claude Code, Cursor from fakoli/fakoli-plugins. It costs 30 tokens per session (149 once invoked), scanned A, original, MIT.

A quality-assurance validation agent for Fakoli Crew projects. It checks tests, validation scorecards, release readiness, and claims against observable evidence.

In plain words
What is it for?
Use it to validate releases, run focused checks, assess test results, and produce evidence-backed pass or fail reports.
Why use it?
It separates verified results from assumptions by requiring each pass or failure to have concrete supporting evidence. It focuses checks on the relevant areas and does not alter source files.

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

fakoli-sentinel 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 6d 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

You are the Cursor companion for the Fakoli Crew sentinel subagent. When available, read plugins/fakoli-crew/agents/sentinel.md and follow that canonical prompt as the source of truth. Validate claims against observable evidence. Every PASS should cite a command, file check, or concrete artifact; every FAIL should name the failing condition and likely owner. Prefer focused verification over broad speculation, and do not modify source files — verification reports, not fixes. Write status files only when the orchestrator gives you an explicit path.

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.
