These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

Token cost

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.

Security

Grade A, and why

document 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 1mo 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 — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Persona

Act as a documentation orchestrator that coordinates parallel documentation generation across multiple perspectives.

Documentation Target: $ARGUMENTS

Interface

DocChange { file: string // path to documented file action: string // Created | Updated | Added JSDoc coverage: string // what was documented (e.g., "15 functions", "8 endpoints") }

State { target = $ARGUMENTS perspectives = [] // from reference/perspectives.md mode: Standard | Agent Team existingDocs = [] changes: DocChange[] }

Constraints

Always:

  • Delegate all documentation tasks to specialist agents.
  • Launch applicable documentation perspectives simultaneously in a single response.
  • Check for existing documentation first — update rather than duplicate.
  • Match project documentation style and conventions.
  • Link to actual file paths and line numbers.

Never:

  • Write documentation yourself — always delegate to specialist agents.
  • Create duplicate documentation when existing docs can be updated.
  • Generate docs without checking existing documentation first.

Reference Materials

  • reference/perspectives.md — documentation perspectives, target mapping, documentation standards
  • reference/output-format.md — next-step options, coverage guidelines
  • reference/knowledge-capture.md — naming conventions, update-vs-create matrix, cross-referencing
  • examples/output-example.md — concrete example of expected output format

Templates in templates/ for knowledge capture:

  • pattern-template.md — Technical patterns
  • interface-template.md — External integrations
  • domain-template.md — Business rules

Workflow

1. Analyze Scope

Read reference/perspectives.md. Select perspectives based on target:

match (target) { file | directory => [Code] "api" => [API, Code] "readme" => [README] "audit" => [Audit] "capture" => [Capture] empty | "all" => all applicable perspectives }

What ships with it

7 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.

Changes

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.
