gh-issue-sync

A tool that keeps GitHub issues as Markdown files in your repository. GitHub is a service for hosting code and tracking work, while Markdown is a plain-text writing format.

In plain words
What is it for?
Use it to pull issues into local files, list or search them, create and close issues, and push local changes back to GitHub.
Why use it?
It lets developers triage, search, edit, and create issues from an editor or terminal instead of switching to GitHub's website.

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

gh-issue-sync 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 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.

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

gh-issue-sync

Syncs GitHub issues to local Markdown files in .issues/open/ and .issues/closed/.

Commands

gh-issue-sync init              # Initialize in git repo
gh-issue-sync pull              # Fetch open issues (--all for closed too)
gh-issue-sync push              # Push local changes (--dry-run to preview)
gh-issue-sync list              # List issues (supports gh issue list flags + --search)
gh-issue-sync new "Title"       # Create issue (--label, --edit)
gh-issue-sync close 42          # Close (--reason completed|not_planned)
gh-issue-sync reopen 42
gh-issue-sync status            # Show local changes
gh-issue-sync diff 42           # Show diff (--remote to re-fetch)

File Format

.issues/open/42-fix-login-bug.md:

---
title: Fix login bug
labels: [bug, priority:high]
assignees: [alice]
milestone: v1.0
state: open
# For closed: state_reason: completed|not_planned
# Optional: parent: 10, blocked_by: [11, 12], blocks: [15]

Issue body in Markdown.

Issue number is derived from the filename, not stored in frontmatter.

Temporary Issues

New issues get a T-prefixed ID (e.g., T1a2b3c). The filename must start with T:

.issues/open/T1a2b3c-my-new-issue.md

On push, the file is renamed to the real issue number (e.g., 42-my-new-issue.md) and number: in frontmatter is updated. Any #T1a2b3c references in other issues are also updated to #42.

Comments

To post a comment when pushing, create a .comment.md file next to the issue:

.issues/open/42.comment.md
.issues/open/42-fix-login-bug.comment.md

Content is plain Markdown. The file is deleted after the comment is posted.

Notes

  • Pull skips conflicts; use --force to overwrite local
Files

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.

Changes

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.
