Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

What it costs to keep this loaded
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 | $0.00035 | $0.01516 |
| Opus 5.5 | $0.00014 | $0.00606 |
| Sonnet 5.5 | $0.00007 | $0.00303 |
| Haiku 4.5 | $0.00003 | $0.00152 |
Grade A, and why
skill-check 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 — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Frontmatter Reference (official fields)
Skills support these fields. Only description is meaningfully required (a
skill with none of these still loads — name defaults to the directory name).
---
name: skill-name # Optional: defaults to directory name; lowercase, hyphenated
description: What it does # Recommended: shown in / menu and used for triggering
when_to_use: When to reach for it # Optional: appended to description for triggering
# (description + when_to_use truncated at 1,536 chars in listings)
user-invocable: true # Optional: default true; false hides from / menu (Skill tool still works)
model: sonnet # Optional: any /model value (sonnet, opus, haiku, fable, best,
# default, opusplan, sonnet[1m], opus[1m], a full model ID) or inherit
effort: medium # Optional: low, medium, high, xhigh, max
allowed-tools: # Optional: pre-approved tools. Accepts a comma-separated string
- Read # OR a YAML list — BOTH are official (list shown here as house style)
- Grep
- Glob
disallowed-tools: # Optional: explicitly blocked tools (string or YAML list)
- WebFetch
context: fork # Optional: run the skill in a subagent
agent: agent-name # Optional: subagent type when context: fork (default: general-purpose)
background: false # Optional (2.1.218+): with context: fork, false waits for the result;
# forked skills run in the background by default
argument-hint: "[issue-number]" # Optional: autocomplete hint shown after the skill name
arguments: target flags # Optional: space-separated argument NAMES for $name substitution
# (e.g. arguments "target flags" -> use $target and $flags in the body).
# NOT a structured array of name/description/required objects.
disable-model-invocation: false # Optional: bool; true also blocks scheduled-task invocation
paths: # Optional: glob patterns that limit where the skill activates
- "src/**/*.ts"
shell: bash # Optional: bash or powershell for inline !`command` blocks
hooks: # Optional: skill-scoped lifecycle hooks (same schema as settings.json)

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-check is a skill published in the GitHub repository claude-world/director-mode-lite (80 stars, last pushed 3d ago), licensed MIT. It adds 35 tokens to every session and 1,516 once invoked, about $0.0001 per session on Opus 5.5. 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.
Other skills, from other repositories
concise
Concise communication mode. Cuts 60-70% of output tokens while keeping natural, readable English. Drops filler, hedging, and pleasantries but maintains grammar and sentence flow. Elaborate on request -- ask for detail and get it, then auto-return to concise. Use when user says "concise mode", "be concise", "less…
session-recap
Document Claude Code sessions by extracting knowledge into cross-referenced documentation. Triggers on "recap the session", "summarize the work", or after significant code changes.
knowledge-bank-lookup
Delegates knowledge bank lookups to Explore subagents with reflections-first strategy that learns from past mistakes. Checks /reflections/ directory before documentation to extract documented failures to avoid and proven approaches to apply. Automatically triggers when user mentions services ([project-a], [project-b]…
kb-ingest
Ingest external sources into the knowledge bank through interactive study or quick filing. Two modes — Quick (summarize → file) and Study (theme-by-theme deep dive with online research and personal notes → multi-layer KB output → optional blog/slack synthesis). Triggers on "ingest this", "study this article", "add to…
kb-lint
Health-check the knowledge bank for orphan documents, stale content, broken WikiLinks, index drift, and missing frontmatter. Generates a severity-graded report. Use this skill whenever the user mentions lint, health check, KB maintenance, stale docs, broken links, orphan pages, missing references, knowledge bank…
session-manager
Set the current session's name, project, tags, or summary on its session note. Use when the user names, tags, or summarizes this session, sets its project, or mentions in passing what this session has been about.
