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 | $0.00170 | $0.03999 |
| Opus 5 | $0.00085 | $0.01999 |
| Sonnet 5 | $0.00034 | $0.00800 |
| Haiku 4.5 | $0.00017 | $0.00400 |
Grade C, and why
github-organization-governance 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 11d 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.

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

Purpose
Bring an organization's settings to a state where policy applies to every repository including the ones created tomorrow, access follows identity rather than memory, and each control produces evidence without anyone collecting it. This skill is a triage layer: it states the baseline an organization must meet, routes the change to the detail that applies, then holds the result to a bounded loop built on reading the applied state back and measuring how much of the fleet it covers.
An organization control that reaches most repositories is not a control. The repositories it misses are where the work that avoids it will happen.
When to use this
- Setting or reviewing organization or enterprise policy: member privileges, base permissions, repository creation, visibility changes, deletion, and forking.
- Requiring two-factor authentication, enforcing single sign-on, or configuring automated provisioning.
- Designing a custom property schema, or populating properties across repositories.
- Creating an organization ruleset, or rolling one out to a set of repositories.
- Reviewing team access, outside collaborators, GitHub App installations, or token policy.
- Restricting which actions repositories may call, or which repositories may use a runner group.
- Configuring audit log retention or streaming, running an access review, or assembling evidence for a compliance framework.
When NOT to use this
- Settings inside a single repository. Use
github-repository-security. - The contents of a workflow file, an
action.yml, or adependabot.yml. Usegithub-actions-security. - Identity provider configuration outside GitHub, beyond the claims GitHub consumes.
- Application code security, which the language skills cover.
What ships with it
4 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.

github-organization-governance is a skill published in the GitHub repository konstruktoid/hardened-images (90 stars, last pushed 3d ago), licensed Apache-2.0. It adds 170 tokens to every session and 3,999 once invoked, about $0.0009 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 2026-08-30.
