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 | $0.00026 | $0.00470 |
| Opus 5 | $0.00013 | $0.00235 |
| Sonnet 5 | $0.00005 | $0.00094 |
| Haiku 4.5 | $0.00003 | $0.00047 |
Grade A, and why
manage-governance 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 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.
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
Manage Governance Policies
You are managing governance policies for the Agent Skill Harbor catalog.
File
- Config:
config/governance.yaml - Zod schema:
web/src/lib/schemas/governance.ts
Schema
usagePolicySchema: 'recommended' | 'discouraged' | 'prohibited' | 'none'
governancePolicySchema: {
usage_policy: UsagePolicy
note?: string
}
governanceSchema: {
policies: Record<string, GovernancePolicySchema> // key = skill path
}
Key Format
Skill path key: github.com/{owner}/{repo}/{skill-file-path}
Examples:
github.com/example-org/code-review/.claude/skills/review/SKILL.mdgithub.com/anthropics/prompt-library/SKILL.md
Actions
Parse the user's intent and execute the appropriate action below.
Set Policy
When the user wants to set a governance policy (e.g., govern github.com/owner/repo/SKILL.md recommended "reason"):
- Read
config/governance.yaml - Find or create an entry under
policieswith the skill path key - Set
usage_policyto one of:recommended,discouraged,prohibited - Optionally set
note - Write back
config/governance.yaml
Remove Policy
When the user wants to remove a governance policy or set it to none:
- Read
config/governance.yaml - Remove the entry from
policies - Write back
config/governance.yaml
List Policies
When the user wants to list governance policies:
- Read
config/governance.yaml - Display a table with: skill path, usage_policy, note
Important Notes
- All changes are made to local files only
- Remind the user to create a PR to apply changes
- After making changes, run
pnpm run build:catalogto regenerate the catalog
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.

manage-governance is a skill published in the GitHub repository skill-mill/agent-skill-harbor (40 stars, last pushed 5mo ago), licensed MIT. It adds 26 tokens to every session and 470 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings.
