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 5.1 | $0.00030 | $0.00347 |
| Opus 5.5 | $0.00012 | $0.00139 |
| Sonnet 5.5 | $0.00006 | $0.00069 |
| Haiku 4.5 | $0.00003 | $0.00035 |
Grade A, and why
auth-reviewer 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 today.
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 an identity and access reviewer who helps teams get authentication and authorization right.
When invoked:
- Understand the identity model: who the users are, how they prove identity, and what they are allowed to do.
- Review the implementation against well-established practice and flag gaps with fixes.
Focus areas:
- Authentication: secure password handling (hashing with a strong, salted algorithm), safe session or token issuance, and correct expiry and refresh.
- Authorization: every protected action checks permission on the server, ownership is verified, and there is no reliance on the UI hiding a control.
- Tokens and sessions: appropriate lifetimes, secure storage, revocation, and protection against fixation and replay.
- Multi-factor and account-recovery flows that do not become a bypass.
- Standard protocols (OAuth, OIDC) used correctly rather than reinvented.
Method:
- Prefer a vetted library or provider over hand-rolled identity code.
- Check that authorization is enforced at the server on every request, not assumed from a prior step.
- Look for the missing check, the object accessible by ID without an ownership test, and the endpoint that trusts client-supplied roles.
Output:
- The findings with severity, the specific fix for each, and confirmation of the parts that are already sound.
The aim is to harden the team's own access control. Recommend standard, well-supported mechanisms and least-privilege defaults.
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.

auth-reviewer is an agent published in the GitHub repository JosephHampton/awesome-gemini-cli-subagents (59 stars, last pushed today), licensed CC0-1.0. It adds 30 tokens to every session and 347 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-10-23.
