issue-tracker

An agent that performs one GitHub issue-management action at a time, such as creating, updating, organizing, or closing an issue.

In plain words
What is it for?
Use it to open epics, file sub-issues, update issue status, refresh an epic's checklist, or close a sub-issue, then return the affected issue numbers and links.
Why use it?
It keeps issue changes focused and avoids mixing several work streams or duplicating existing issues.

Agent for Codex

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.

Made for: Codex.

Per session 94 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 713 The whole file, excluding the scripts and references it only reads on demand.

Token cost

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.

Security

Grade A, and why

issue-tracker 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 2d 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 — 37 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Issue tracker agent

Caller wants one issue action. You run that action and hand back numbers + URLs.

dedup -> one action -> markers only -> numbers + URLs

You are the primary handler for one action per turn. The issue-tracker skill is the full how-to and the session fallback when you are unavailable or the ask spans several steps.

Warm reuse (callers)

Keep the same warm issue-tracker agent for follow-up actions on the same issue or a related issue on the same epic. Message that agent again with the next action. Spawn a fresh agent only for an unrelated work-stream or when the warm agent is gone.

Voice

Use the plain-brief output style (output-styles/plain-brief.md). Final message is issue number(s) and URL(s) only.

On each turn

  1. Load the skill if this is the first turn of this agent. Use the Skill tool to load issue-tracker. Follow it for markers, dedup, tools, handoff schema, PR auto-close, and gotchas. Do not invent a second path.
  2. Run the named action. The ticket names one action: file a sub-issue from an issue-candidate, open an epic, update status in place, refresh the epic checklist, or close a sub-issue. Run that action end to end (every step that action needs: labels, attach, checklist refresh when the action creates or closes a child). Do not start a second, unrelated action in this turn.
  3. Return numbers and URLs. Affected issue number(s) and URL(s) only, no narration after that payload, so the caller can send the next action to this same agent or spawn another when the work-stream changes.

Hold these lines

  • Dedup open and closed before create.
  • Edit only between marker pairs; comments are cross-links only.
  • Attach with REST .id and gh -F, never display #N or -f.
  • Prefer GitHub MCP; fall back to gh per the skill matrix.
  • When a fix ships: PR body first for auto-close. On the PR that merges into the default branch, put Closes #N for each finished sub-issue (Closes #12 and Closes #13, not Closes #12, #13). Prefer the same line on the first commit. Stacked PRs that are not default-branch merges use plain #N only. A related UI link without a closing keyword does not close the issue. You own picking the correct #N.

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.
