implement-issue

A workflow for implementing a GitHub issue, which is a tracked task or bug in a code repository. It covers planning, coding, review, fixes, and creating a pull request, including dependent stacked pull requests.

In plain words
What is it for?
It is for loading issue context, deciding whether to build on another branch, implementing the change, reviewing it, fixing problems, and preparing a pull request.
Why use it?
It gives the agent a defined path from issue details to reviewed code and checks whether prerequisite work is complete.

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: Claude Code.

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

implement-issue 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 yesterday.

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.

The opening of the file, as written. The whole thing — 337 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Implement Issue Workflow

You are orchestrating a Plan → Implement → Review → Remediate → PR cycle for a GitHub issue, with support for stacked PRs when issues form a linear dependency chain.

Input

The user will provide a GitHub issue number: $ARGUMENTS

Phase 1: Load Context & Determine Stacking

  1. Run the context loader script to fetch all issue data in one shot:
    .claude/scripts/load-issue-context.sh <number>
    
    This fetches: issue details, all comments, milestone issues, dependency states, open feat/ PRs, and git state.
  2. Read CLAUDE.md and MEMORY.md for project conventions
  3. From the script output, verify all dependencies are complete (closed/merged or open PR in current stack)

Stacking Decision

Determine whether this issue should stack on a previous branch or start fresh from main.

Algorithm:

  1. Find this issue's position in any implementation sequence
  2. Look at the previous issue in the sequence (by step number, not by dependency list)
  3. If the previous issue has an unmerged PR branch that is an ancestor of this issue's dependencies → stack on that branch
  4. If the previous issue is already merged to mainbranch from main
  5. If this issue has multiple unmerged predecessors on different branches → this is a merge point. STOP and tell the user the predecessor PRs must be merged first.

In practice: The script output includes an === Open Feature Branches === section listing all open PRs on feat/ branches and their targets. Use this to determine stacking:

# If stacking:
git checkout <predecessor-branch>
git checkout -b feat/<this-issue>

# If fresh from main (works in worktrees where local main may not exist):
git fetch origin main
git checkout -b feat/<this-issue> origin/main

Report the stacking decision to the user:

Stacking: feat/<this-issue> → feat/<predecessor-issue> → ... → main
PR will target: feat/<predecessor-issue>

or:

Fresh branch: feat/<this-issue> from main
PR will target: main

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.

implement-issue is a command published in the GitHub repository mpecan/tokf (195 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,101 tokens. 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 2026-08-30.
