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

github-repo-scout 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 12d 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.

What it actually says

GitHub Repo Scout

When to Use

  • User says github.com or task matches this capability
  • User says check this repo or task matches this capability
  • User says scout repo or task matches this capability
  • User says what is this project or task matches this capability

Workflow

  1. Parse owner/repo from URL; reject non-GitHub hosts unless user confirms.
  2. Fetch README and top-level tree via public API or git clone (read-only).
  3. Compare README claims vs actual committed files (note drift).
  4. Check if repo exists locally in workspace or common clone paths.
  5. Summarize: purpose, install steps, risks, suggested actions (clone, audit, review).
  6. Do not access private repos without authenticated user context.

Integrations

  • oss-repo-maintainer
  • defensive-mcp-audit
  • skill-rubric-reviewer

Error Handling

Failure Response
404/private repo State access limitation; ask user to clone locally.
Rate limited Backoff; use local clone if available.

Gotchas

  • Public repos only unless user has authenticated MCP/GitHub access.

Safety & Ethics (Publication-Ready)

This skill is designed for public distribution. Constraints:

  • Read-only repository inspection.
  • No harvesting of tokens, secrets, or private issue content.
  • Do not auto-clone into system directories without user approval.

Prohibited actions

  • No unauthorized access, malware, or harmful automation
  • No silent exfiltration of data, credentials, or telemetry
  • No destructive system changes without hitl-approver
  • No publication of user PII or environment secrets in outputs

Example

Input: User request matching triggers above. Output: Structured result per workflow; local artifacts only unless user opts in.

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.
