issue_update is a skill for Claude Code from MarcusJellinghaus/mcp-tools-sql. It costs 10 tokens per session (490 once invoked), scanned A, a copy of issue_update, MIT.

A helper for updating an existing GitHub issue with clearer requirements and implementation ideas based on an earlier analysis discussion.

In plain words
What is it for?
Use it to fetch an issue, refine its title and body, optionally record a base branch, and apply the changes on GitHub.
Why use it?
It avoids rewriting issue details manually and keeps the issue aligned with the decisions already made.

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_update 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 1mo 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.

Origin

This is a copy

92% identical to issue_update — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Update GitHub Issue

Based on our prior /issue_analyse discussion, update the GitHub issue with refined content.

Instructions:

  1. If no issue context is found from prior analysis, respond: "No issue context found. Please run /issue_analyse <number> first."

  2. First, fetch the current issue content: Call mcp__mcp-workspace__github_issue_view with the issue number.

  3. Draft updated issue text with:

    • Clear, concise title
    • Well-structured body with implementation ideas
  4. Write the issue body to a temp file (avoids bash escaping issues with markdown):

mcp__mcp-workspace__save_file(file_path=".scratch/issue_body_temp.md", content=body_content)
  1. Update the issue using --body-file:
gh issue edit <issue_number> --title "NEW_TITLE" --body-file .scratch/issue_body_temp.md
  1. Clean up the temp file:
mcp__mcp-workspace__delete_this_file(file_path=".scratch/issue_body_temp.md")

Editing Base Branch:

  • To add a base branch: Insert ### Base Branch section with the branch name
  • To change a base branch: Update the content under the existing section
  • To remove a base branch: Delete the entire ### Base Branch section

The base branch must be a single line. Multiple lines will cause an error during branch creation.

The updated issue should include:

  • Summary of the requirement
  • Discussed implementation approach (concise)
  • ## Constraints & Rationale — non-obvious gotchas and the "why" behind decisions. Skip if none identified.
  • ## Decisions table — decided topics so /issue_analyse won't re-ask. Skip if none yet.
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.
