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.

SkillSpector: 1 finding, up to medium
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 →
- medium Data Exfiltration · line 39 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00047 | $0.00876 |
| Opus 5.5 | $0.00019 | $0.00350 |
| Sonnet 5.5 | $0.00009 | $0.00175 |
| Haiku 4.5 | $0.00005 | $0.00088 |
Grade A, and why
github-openapi-skill 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 2mo 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 — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GitHub REST API Skill
Use this skill to run GitHub REST API operations through uxc + OpenAPI.
Reuse the uxc skill for shared execution, auth, and error-handling guidance.
Prerequisites
uxcis installed and available inPATH.ghis installed and already authenticated withgh auth login.- Network access to
https://api.github.com. - Access to the official GitHub REST OpenAPI schema URL:
https://raw.githubusercontent.com/github/rest-api-description/main/descriptions/api.github.com/api.github.com.json
Authentication
Preferred Path: Import local gh auth into uxc
Import the current GitHub CLI token into a local uxc bearer credential and create a standard GitHub API binding:
uxc auth credential import github --from gh
This creates:
- credential:
github - binding:
github-api - bound host:
https://api.github.com
Verify the binding:
uxc auth binding match https://api.github.com/repos/holon-run/uxc
Optional Path: Manual bearer token
If gh is unavailable, configure a PAT manually:
uxc auth credential set github \
--auth-type bearer \
--secret-env GITHUB_TOKEN
uxc auth binding add \
--id github-api \
--host api.github.com \
--path-prefix / \
--scheme https \
--credential github \
--priority 100
Do not commit GitHub tokens or hardcode them in this skill or repository.
Core Workflow
-
Use fixed link command by default:
command -v github-openapi-cli- If missing, create it:
uxc link github-openapi-cli https://api.github.com --schema-url https://raw.githubusercontent.com/github/rest-api-description/main/descriptions/api.github.com/api.github.com.json github-openapi-cli -h
-
Inspect operation schema first:
github-openapi-cli get:/user -hgithub-openapi-cli get:/repos/{owner}/{repo} -hgithub-openapi-cli get:/repos/{owner}/{repo}/issues -h
-
Execute reads before writes:
github-openapi-cli get:/usergithub-openapi-cli get:/repos/{owner}/{repo} owner=holon-run repo=uxcgithub-openapi-cli get:/repos/{owner}/{repo}/issues owner=holon-run repo=uxc state=open per_page=10github-openapi-cli get:/repos/{owner}/{repo}/pulls owner=holon-run repo=uxc state=open per_page=10
What ships with it
3 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-openapi-skill is a skill published in the GitHub repository holon-run/uxc (119 stars, last pushed 1mo ago), licensed MIT. It adds 47 tokens to every session and 876 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
