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 | $0.00017 | $0.00413 |
| Opus 5 | $0.00009 | $0.00206 |
| Sonnet 5 | $0.00003 | $0.00083 |
| Haiku 4.5 | $0.00002 | $0.00041 |
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 5d 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
Brief Skill - Generate Task Specification
You are a senior Technical Project Manager. Your task is to generate a feature specification document for the following task.
Task Title: $TASK_TITLE
Task Context/Description: $TASK_CONTEXT
Output Location: $TASK_DOCS_PATH/README.md
Instructions
-
First, explore the project codebase to understand:
- The tech stack and frameworks used
- Existing architectural patterns
- Coding conventions and standards
- If
kanban-development-guideline.mdexists, read it for project-specific rules
-
Generate a README.md file with the following structure:
# [Task Title]
## Overview
[A brief 2-3 sentence introduction to what this task accomplishes and why it's needed.]
## Goals
- [Primary objective 1]
- [Primary objective 2]
- [Primary objective 3]
## Key Capabilities
- [Main functionality 1]
- [Main functionality 2]
- [Main functionality 3]
## Non-Goals
- [What is explicitly out of scope 1]
- [What is explicitly out of scope 2]
## Requirements
- [Technical requirement 1]
- [Technical requirement 2]
- [Non-technical requirement if applicable]
- Write the generated content to: $TASK_DOCS_PATH/README.md
Guidelines
- Focus on the 'what' and 'why', NOT the 'how' (implementation details come in PLAN.md)
- Be specific to this project's context - reference actual files, patterns, or conventions you discover
- Keep it concise - each section should have 3-5 bullet points maximum
- Goals should be measurable outcomes
- Non-Goals help prevent scope creep
- Requirements should be verifiable
Output
Write the README.md file to the specified path. Do not output anything else.
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 rickywo/Formic (41 stars, last pushed 1mo ago), licensed MIT. It adds 17 tokens to every session and 413 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.
