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 | $0.00038 | $0.01120 |
| Opus 5 | $0.00019 | $0.00560 |
| Sonnet 5 | $0.00008 | $0.00224 |
| Haiku 4.5 | $0.00004 | $0.00112 |
Grade B, and why
agent-skills scanned grade B with 1 finding 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 today.
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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
- **Antigravity paths**: `~/.gemini/config/skills` is the shared global path; the CLI-only `~/.gemini/antigravity-cli/skills` creates stale copies, so keep one. How it starts
The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Skills
Author, validate, publish, and install Agent Skill packages for Antigravity, Claude Code, Codex, Copilot, Grok, and OpenCode. skillify owns extracting a skill from a session; skill-security-review owns the trust review of third-party packages.
Author
- Scaffold:
skills init <name>; the directory name and the lowercase hyphenated frontmatternamestay identical, and the description is one sentence stating capability then trigger, never a workflow summary. - Package: keep
SKILL.mdfocused; scripts, references, and templates live one level deep and are linked directly fromSKILL.mdper the package rules. - Fit the catalog: read neighbors with overlapping descriptions and link them instead of copying; a first-party skill also declares its CLI names in
skills/contracts.json.
Validate
- Isolate the candidate: copy only the skill to
<candidate-root>/<slug>/SKILL.mdwith its linked resources; the publisher takes the parent root, and catalog-relative sibling links do not survive a standalone install. - Dry run (proves Agent Skills compatibility, not safety):
gh skill publish --dry-run <candidate-root> - Catalog gate: a first-party skill also passes
mise run check:skillsandmise run test(contracts, links, routing probes). - Host discovery: inspect whether the skill name and full description survive each host's metadata budget with the read-only listing commands in host discovery; front-load routing cues and record any truncation, because a listed skill is not proof it is followed.
Publish
- Authority:
gh skill publishadds a topic, a tag, and a GitHub release, so obtain explicit publication authorization for the exact repository, candidate root, and version, then confirm the intended commit and rerun the dry run. - Publish once, stopping on any partial failure instead of retrying with another tag:
gh skill publish <candidate-root> --tag <vX.Y.Z> - Receipt: record repository, commit, tag, and release URL; without the remote receipt the package is validated, not published.
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.

agent-skills is a skill published in the GitHub repository fmind/dot (4 stars, last pushed today), licensed MIT. It adds 38 tokens to every session and 1,120 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
