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 | $0.00109 | $0.01933 |
| Opus 5 | $0.00055 | $0.00966 |
| Sonnet 5 | $0.00022 | $0.00387 |
| Haiku 4.5 | $0.00011 | $0.00193 |
Grade C, and why
address-issue 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 3d 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.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.
<!-- prettier-ignore --> How it starts
The opening of the file, as written. The whole thing — 218 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Address Issue
Fetch a GitHub issue, analyze it, plan and execute the work in the current branch, and commit with issue references.
Options
The user may provide these options inline:
- --dry-run: Fetch and analyze the issue, present the plan, but do not make changes
- --no-commit: Make changes but do not commit them
- --commit-per-change: Commit after each logical change instead of grouping at the end
Workflow
1. Find the Issue
The user provides either an issue number or descriptive text.
By number:
gh issue view NUMBER --json number,title,labels,assignees,body,state
By text (fuzzy search):
gh issue list --search "USER_TEXT" --state all --json number,title,labels,state --limit 10
If the search returns exactly one result, proceed automatically with that issue without asking for additional confirmation.
If the search returns multiple results, present them to the user and ask which one to use.
If no results, try broadening the search or ask the user to refine their query.
2. Check Issue State
If the issue is closed, warn the user and ask whether to proceed. Do not proceed without confirmation.
3. Mark Issue In Progress
If the issue is open, signal that work is starting. Skip this step for closed issues.
Self-assign:
gh issue edit NUMBER --add-assignee @me
Ensure the label exists, then add it:
gh label create "in progress" --description "Work is actively being done" --color FBCA04 2> /dev/null || true
gh issue edit NUMBER --add-label "in progress"
The gh label create command is safe to run even if the label already exists. 2> /dev/null suppresses the "already exists" error and || true ensures a zero exit code so the subsequent command always runs. This ensures the label is available before gh issue edit --add-label attempts to use it, since gh does not auto-create labels.
Self-assignment is idempotent, safe to re-run if the assignee already exists.
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.

address-issue is a skill published in the GitHub repository cboone/agent-harness-plugins (2 stars, last pushed 1mo ago), licensed MIT. It adds 109 tokens to every session and 1,933 once invoked, about $0.0005 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 2026-08-31.
