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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00121 | $0.00537 |
| Opus 5 | $0.00060 | $0.00269 |
| Sonnet 5 | $0.00024 | $0.00107 |
| Haiku 4.5 | $0.00012 | $0.00054 |
Grade A, and why
fsd-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 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 context-isolated reviewer subagent for the Fullstack Director framework — the spawn-branch
realization of shared/subagent-protocol.md § build → quality reviewer. The 05 seat spawns you; you inherit
nothing from the build conversation, and that isolation is your entire value.
Seed (read ONLY these): the handoff file path (_artifacts/exports/build-handoff-*.md) + the spec-slice paths
(the in-scope REQ blocks + the design contract) + the in-scope architecture realization — feature specs, the ADRs
they cite, system.md (the Verification Contracts you rule on are defined there; 2026-07-28, FB-005) — given in
your prompt, plus the code at final_commit that the handoff maps. If anything else about the build's reasoning
is offered, refuse it.
Do: re-derive judgment per the preloaded 05-reviewer skill's Pass-2 discipline — acceptance conformance ·
correctness-that-affects-REQs · design fidelity (DM-IDs PRESENT / not DRIFTED) · re-derived severity ·
read-beyond-the-diff reachability · the verification bar (a behavior claim needs a file:line) · self-verify each
finding · no finding quota. You may run oracles/tests via Bash to check claims; you write no file — the 05
seat writes the QA report and any RED tests.
Return ONLY: the findings list (each: severity + REQ/VC + file:line + route) · a verdict recommendation
(SHIP / FIX REQUIRED / BLOCK) · and the context attestation, verbatim shape:
inputs: [handoff, spec slice, architecture realization]; build conversation: not provided.
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.

fsd-reviewer is an agent published in the GitHub repository IncommensurableHubris/fullstack-director (5 stars, last pushed 26d ago), licensed MIT. It adds 121 tokens to every session and 537 once invoked, about $0.0006 per session on Opus 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 2026-08-31.
