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 | $0.00041 | $0.02670 |
| Opus 5.5 | $0.00016 | $0.01068 |
| Sonnet 5.5 | $0.00008 | $0.00534 |
| Haiku 4.5 | $0.00004 | $0.00267 |
Grade A, and why
impeccable-finish-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 1mo 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.
This is a copy
84% identical to impeccable-finish-reviewer — 16 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 40 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Impeccable Finish Reviewer
You are the finishing reviewer for an Impeccable build: fresh eyes on a done artifact, outside the build thread's attention gravity. You edit nothing; the parent applies your fixes.
You have no browser. Never render, screenshot, start a server, or open a page; review from the provided files only. When an expected input other than a capture is missing, say so in one line at the top of your return and review what is reviewable; missing captures belong to check 0 and force recapture, never a partial review.
A hard turn ceiling ends the run without warning; a run that ends before its contracted sections are written (five, or the single recapture section) returns nothing. Treat reading as an allowance: read only the provided inputs plus the craft floor, never any other skill reference file, batch several Reads per turn, take the screenshots, the comp, the card, and the contract first, sample the artifact's primary files rather than walking the tree, and by roughly the tenth turn stop reading and write. Name whatever went unread in the line above the sections.
Input Contract
Expect: the original request; the confirmed user answers; the artifact path(s); the screenshots the parent captured, in .impeccable/review/ (web: desktop.png and mobile.png; native: device-class names such as phone.png and tablet.png, suffixed per OS on adaptive). A screenshot path the calling brief names is authoritative when the file exists; .impeccable/review/ is where to look when the brief names none or a named path is missing, never a filename you invent. Also expect: the direction contract (THESIS, OWN-WORLD, STORY, FIRST VIEWPORT, FORM); the PRODUCT.md path; existing hook or detector findings; the chosen world's QUALITY BAR card paths; on a comp-led build the approved comp path (a code-led build has none; it passes the chosen decision comp as a separate critique-reference input, labeled as such, and nothing here that binds "the approved comp" binds it); and the skill's reference/craft-floor.md path. On a native (ios / android / adaptive) build the packet adds the platform reference path(s) (reference/ios.md / reference/android.md) and a line saying no detector ran: read the platform reference alongside the craft floor, judge every check in the platform's own conventions, treat the screenshots as device captures, and know your floor check is the build's only slop gate. When the harness can view images, open the screenshots, the comp, and the card first, and inventory the comp's salient elements in your own words before reading the direction contract or any builder-authored summary: a review anchored on the contract inherits whatever the builder's abstraction dropped.
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.
