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.

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 | $0.00094 | $0.01342 |
| Opus 5 | $0.00047 | $0.00671 |
| Sonnet 5 | $0.00019 | $0.00268 |
| Haiku 4.5 | $0.00009 | $0.00134 |
Grade C, and why
rafter-skill-review scanned grade C with 2 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 yesterday.
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.

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Rafter Skill Review — Vet Before You Install
Skills are executable context. Installing one gives it Read, sometimes Bash, sometimes network — with your identity and your files. Treat installation the way you treat curl | sh: don't.
Before you copy any third-party SKILL.md, MCP manifest, Cursor rule, or agent extension into your machine, run this skill.
This skill replaces
rafter agent audit-skill(still usable but deprecated — emits a stderr warning and aliases torafter skill review).
Step 0: Always run the deterministic pass first
rafter skill review <path-or-git-url> # emits JSON to stdout
rafter skill review <path> --format text # human-readable summary
The command:
- pulls the skill (if a URL, does a shallow clone into a temp dir),
- runs
rafter secretsover the tree, - extracts URLs, high-risk shell patterns, obfuscation signals,
- reads
SKILL.mdfrontmatter (allowed-tools,version, etc.), - prints a structured JSON report — see
shared-docs/CLI_SPEC.md§rafter skill review.
Exit code 0 means the deterministic pass found nothing. That does NOT mean the skill is safe. LLM prompt injection, sneaky data practices, and authorship fraud are invisible to regex. Always follow up with the Choose-Your-Adventure branch below.
Choose Your Adventure
Pick exactly one branch. Read only that sub-doc — do not flood your context with all six.
(a) I am installing a brand-new skill
Use this when: you've never had this skill on this machine, and you want to know if it's safe to install for the first time.
Walk in order:
Read docs/authorship-provenance.md— who wrote it, how old, how signed, how widely installed. Stop early if provenance is weak.Read docs/malware-indicators.md— grep for obfuscation, binary blobs, postinstall scripts, known-bad URL patterns.Read docs/prompt-injection.md— scan prose for hidden instructions, zero-width characters, conflicting directives in long files.Read docs/data-practices.md— which files/paths does it read and write, what network calls, does it silently escalate viaallowed-tools.Read docs/telemetry.md— phone-home URLs, analytics SDKs, anonymous-but-trackable IDs.
What ships with it
6 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.

rafter-skill-review is a skill published in the GitHub repository Raftersecurity/rafter-cli (27 stars, last pushed 3d ago), licensed MIT. It adds 94 tokens to every session and 1,342 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
