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 | $0.00028 | $0.00908 |
| Opus 5 | $0.00014 | $0.00454 |
| Sonnet 5 | $0.00006 | $0.00182 |
| Haiku 4.5 | $0.00003 | $0.00091 |
Grade A, and why
my-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 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.
How it starts
The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.
These two fields are the only ones required. name must be lowercase with hyphens, max 64 characters, and match the parent directory name. description is what Claude reads at startup to decide when the skill is relevant (max 1024 characters).
Optional Frontmatter Fields
Add any of these to the --- block above to customise behaviour:
| Field | Example | Purpose |
|---|---|---|
argument-hint |
[issue-number] |
Hint shown during autocomplete to indicate expected arguments |
disable-model-invocation |
true |
Prevent Claude from auto-loading. User must type /name explicitly. Use for deploys, sends, destructive ops |
user-invocable |
false |
Hide from the / menu. Claude can still load it automatically. Use for background knowledge |
allowed-tools |
Read, Grep, Bash(npm *) |
Tools Claude can use without asking permission. Space-delimited, supports patterns |
model |
claude-sonnet-4-6 |
Override the model when this skill is active. Useful for cost control |
context |
fork |
Run in an [isolated subagent](^A separate Claude instance with its own context. The skill content becomes the subagent's system prompt). Skill content becomes the subagent's prompt |

Explore |
Which subagent runs when context: fork. Built-in: Explore, Plan, general-purpose, or custom from .claude/agents/ |

Body Content
Everything below the frontmatter is the instruction body. Claude reads this when the skill is activated. Write whatever helps Claude perform the task. There are no format restrictions.
Good body content includes:
- Step-by-step instructions for the task
- Examples of inputs and expected outputs
- Common edge cases and how to handle them
- References to supporting files in this skill folder
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

my-skill is a skill published in the GitHub repository LukeRenton/explore-claude-code (308 stars, last pushed 23d ago), licensed MIT. It adds 28 tokens to every session and 908 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.
