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 | $0.00014 | $0.00649 |
| Opus 5 | $0.00007 | $0.00324 |
| Sonnet 5 | $0.00003 | $0.00130 |
| Haiku 4.5 | $0.00001 | $0.00065 |
Grade A, and why
brief 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/brief -- Generate a decision brief
The user wants a compiled output document from the current sprint.
Arguments
$ARGUMENTS
Optional: output format (pdf, html, md). Default: html.
Instructions
-
Run
wheat_compileto ensure compilation is current and there are no blocking conflicts.- If compilation fails due to unresolved conflicts, stop and suggest
/resolve.
- If compilation fails due to unresolved conflicts, stop and suggest
-
Check sprint readiness via
wheat_status:- Minimum 5 active claims to generate a meaningful brief
- At least 2 topics covered
- Warn if all claims are the same type (type monoculture)
-
Read
compilation.json-- this is the source of truth, never read claims.json directly for output. -
Read the template at
${CLAUDE_PLUGIN_ROOT}/skills/_templates/sidebar-brief.htmlfor the canonical accessible HTML structure. All generated HTML MUST follow this template exactly. Note: the path uses${CLAUDE_PLUGIN_ROOT}because the template lives in the Grainulator plugin directory, not the user's repo. -
Generate the brief using
mill_convert:- Format: user-requested or default to HTML
- Structure: Executive summary, key findings by topic, risks and mitigations, recommendations, evidence appendix
- Include claim IDs as references throughout
-
WCAG compliance checklist -- first read and apply every item from
${CLAUDE_PLUGIN_ROOT}/skills/_templates/wcag-shared.md, then verify these brief-specific items:-
<nav aria-label="Table of contents">wrapping sidebar links -
aria-current="page"on active sidebar link (JS IntersectionObserver updates this) - Heading hierarchy:
<h1>page title,<h2>sections,<h3>subsections -- never skip levels - All
<table>elements have<caption>and<th scope="col|row"> - Mobile sidebar uses
<details><summary>disclosure, notdisplay: none - Tags include text prefix (e.g., "Tested: verified"), never color alone
-
-
Write output to
output/brief.<ext>in the sprint directory.
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.

brief is a skill published in the GitHub repository grainulation/grainulator (86 stars, last pushed 4mo ago), licensed MIT. It adds 14 tokens to every session and 649 once invoked, about $0.0001 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 2026-08-30.
