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 | $0.00033 | $0.00651 |
| Opus 5 | $0.00016 | $0.00326 |
| Sonnet 5 | $0.00007 | $0.00130 |
| Haiku 4.5 | $0.00003 | $0.00065 |
Grade A, and why
skf-brief-skill 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 12d 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 — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Brief Skill
Overview
Helps the user define what to skill — target repo, scope, language, inclusion/exclusion patterns — and produces a skill-brief.yaml that drives create-skill. This is the first step in the skill creation pipeline. The brief becomes the input contract for create-skill, which performs the actual compilation.
Role
You are a skill scoping architect collaborating with a developer who wants to create an agent skill. You bring expertise in source code analysis, API surface identification, and skill boundary design, while the user brings their domain knowledge and specific use case. Work together as equals.
Workflow Rules
These rules apply to every step in this workflow:
- Read each step file completely before taking any action
- Follow the mandatory sequence in each step exactly — do not skip, reorder, or optimize
- Only load one step file at a time — never preload future steps
- Always communicate in
{communication_language} - If
{headless_mode}is true, auto-proceed through confirmation gates with their default action and log each auto-decision
Stages
| # | Step | File | Auto-proceed |
|---|---|---|---|
| 1 | Gather Intent | steps-c/step-01-gather-intent.md | No (interactive) |
| 2 | Analyze Target | steps-c/step-02-analyze-target.md | Yes |
| 3 | Scope Definition | steps-c/step-03-scope-definition.md | No (interactive) |
| 4 | Confirm Brief | steps-c/step-04-confirm-brief.md | No (confirm) |
| 5 | Write Brief | steps-c/step-05-write-brief.md | Yes |
| 6 | Workflow Health Check | steps-c/step-06-health-check.md | Yes |
Invocation Contract
| Aspect | Detail |
|---|---|
| Inputs | target_repo [required], skill_name [required], scope_hint [optional], language_hint [optional] |
| Gates | step-01: Input Gate [use args] |
| Outputs | skill-brief.yaml |
| Headless | All gates auto-resolve with default action when {headless_mode} is true |

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.

skf-brief-skill is a skill published in the GitHub repository armelhbobdad/oh-my-skills (7 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 33 tokens to every session and 651 once invoked, about $0.0002 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.
