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 | $0.00000 | $0.00267 |
| Opus 5 | $0.00000 | $0.00133 |
| Sonnet 5 | $0.00000 | $0.00053 |
| Haiku 4.5 | $0.00000 | $0.00027 |
Grade A, and why
github_write 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 yesterday.
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 Write
Create, modify resources in GitHub. Use github_api.
Canonical tool: github_api
Write actions
create_issue— open issue (args: repo, title, body, labels, assignees)comment_issue— post comment (args: repo, issue_number, body)create_pr— open PR (args: repo, head, base, title, body, draft)commit_file— create/update single file (args: repo, path, branch, content, message)trigger_workflow— manual dispatch (args: repo, workflow_id, ref, inputs)
Legacy tools
github_create_issue, github_create_pr, github_commit_file — back-compat only. Prefer github_api.
Guidelines
- Confirm before creating public issues/PRs.
- Descriptive titles, context in body.
commit_file: backend auto-resolves existingsha— no need to fetch it.
Example
[{"name": "github_api", "args": {"action": "create_issue", "repo": "myorg/myapp", "title": "feat: user export", "body": "Users want CSV export…"}}]
What ships with it
1 file 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_write is a skill published in the GitHub repository ParendumOU/Nexora (19 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 267 tokens. 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.
