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 | $0.00016 | $0.02525 |
| Opus 5 | $0.00008 | $0.01262 |
| Sonnet 5 | $0.00003 | $0.00505 |
| Haiku 4.5 | $0.00002 | $0.00252 |
Grade C, and why
PR: Review scanned grade C 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 10d 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.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.
<!-- What partition-findings.mjs does: documentation of its behaviour, not instructions for the model to reimplement. --> The source is not reproduced here
No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
What ships with it
1 file 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.

PR: Review is a skill published in the GitHub repository JasonWarrenUK/goblin-mode (5 stars, last pushed 2d ago), with no licence file. It adds 16 tokens to every session and 2,525 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
code-review
Code review practices with technical rigor and verification gates. Use for receiving feedback, requesting code-reviewer subagent reviews, or preventing false completion claims in pull requests.
argos
A software inspection skill that checks an implementation against design documents such as API specifications, quality-assurance scenarios, flow diagrams, and other project specifications.
code-reviewer
A pull-request review policy layer that adds checks beyond ordinary bug and quality review. A pull request is a proposed code change waiting to be merged into a project.
naming-analyzer
Suggest better variable, function, and class names based on context and conventions. Use only when the user explicitly asks "what should I call this", "better name for", "rename this", "naming suggestion", or explicitly requests a naming review.
verify-implementation
A coordinator that runs every verification skill registered in a project and combines the results into one report. It also suggests how to fix issues and supports rechecking after approved changes.
antigravity
Use Google Antigravity CLI (agy) for independent code or plan review, large-context analysis, and a second-model opinion. Trigger on Antigravity CLI, agy, Google CLI review, or requests that previously used the Gemini CLI runtime.
