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 | $0.00063 | $0.00704 |
| Opus 5 | $0.00032 | $0.00352 |
| Sonnet 5 | $0.00013 | $0.00141 |
| Haiku 4.5 | $0.00006 | $0.00070 |
Grade A, and why
skill-management 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 8d 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.

Workflow Creation
Create a workflow when a job needs multiple skills in a repeatable order.
Each workflow should include:
- Goal
- When to use
- Skills
- Steps
- Verification
- Output
Also add or update the matching entry in data/workflows.json with:
idtitledescriptionpathrecommendedSkillssteps
Skill Creation Workflow
-
Define the job
- What task does this skill make repeatable?
- What trigger should load it?
- What should the agent do differently after loading it?
-
Write metadata
namemust be lowercase and hyphenated.descriptionmust include task, trigger, and use cases.
-
Write the body
- Keep it procedural.
- Prefer workflow steps and rules.
- Add output format only when consistency matters.
-
Add references only when needed
- Put long syntax tables, examples, or domain docs in
references/. - Keep references one level deep from
SKILL.md.
- Put long syntax tables, examples, or domain docs in
-
Classify status
- Shippable skills go into a domain bucket.
- Drafts go into
in-progress/. - Old skills go into
deprecated/with a short reason in the file.
Bucket Status Skills
The status buckets also contain their own operating skills:
in-progress- prototype and promote draft skills.personal- keep user-specific instructions private and scoped.deprecated- retire stale skills with replacement guidance.
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.

skill-management is a skill published in the GitHub repository ntaffzii/Skill-Agents (4 stars, last pushed 6d ago), licensed MIT.
