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.

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 | $0.00124 | $0.03585 |
| Opus 5.5 | $0.00050 | $0.01434 |
| Sonnet 5.5 | $0.00025 | $0.00717 |
| Haiku 4.5 | $0.00012 | $0.00359 |
Grade A, and why
ghx 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 7d 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 — 344 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ghx Skill
ghx is an extended GitHub CLI.
It talks to the GitHub GraphQL API directly to provide three kinds of capability:
- Cached browsing — fetches issues, pull requests, and their comments and caches every result locally (SQLite at
~/.cache/ghx/cache/cache.dbby default, or one JSON file per entry under~/.cache/ghx/cache/<host>/<owner>/<repo>/with--storage file) to minimise API calls. - Comment operations — inline review comments, line-range comments, thread replies, pending reviews, and a local "stash" for offline review comments, none of which the standard
ghCLI supports. - Remote execution —
ghx rpc serveexposes the same operations over JSON-RPC, and--remote <url>runs any command against that server instead of locally.
Prerequisites
Binary
Check whether the binary is on PATH; install from the latest release if not:
if ! command -v ghx &>/dev/null; then
go install github.com/tomzxcode/ghx@main
fi
Pre-built binaries are also available at https://github.com/TomzxCode/ghx/releases/tag/latest.
Authentication
ghx reads GH_TOKEN or GITHUB_TOKEN from the environment, and falls back to gh auth token (GitHub CLI).
Set the token if neither is available:
export GH_TOKEN=<token>
Target repository
All commands accept --repo [HOST/]OWNER/REPO (or -R).
When omitted, the repo is auto-detected from the origin remote of the current directory.
Confirm the target before running expensive or write operations:
git remote get-url origin
Cached browsing
Pre-populate the cache
Run cache to populate and refresh the local cache, so subsequent list/view commands are served instantly from disk:
ghx cache # delta refresh from the last cache write
ghx cache --repo owner/repo
ghx cache --if-stale # skip while the cache is newer than --cache-duration (60 min)
ghx cache --if-stale --cache-duration 120 # ... newer than 2 hours
ghx cache --since 2026-09-01 # refresh entries created/updated since a date
ghx cache --type issues # refresh only issues (or prs)
ghx cache --force # discard resume state and do a full re-fetch
ghx cache --retries 5 # retry transient errors (default 2; total attempts = retries + 1)
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.

ghx is a skill published in the GitHub repository tomzx/agents (13 stars, last pushed yesterday), licensed MIT. It adds 124 tokens to every session and 3,585 once invoked, about $0.0005 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 2026-09-03.

Prepare and merge an owner-selected PR batch with contributor credit and exact-candidate admission. Use for a pasted PR list; combined focused validation is diagnostic, and every actual landing still requires its applicable checks and authorization.
