implement-issue

implement-issue is a skill for Claude Code from curie-eng/curie. It costs 38 tokens per session (5,675 once invoked), scanned B, original, Apache-2.0.

A workflow guide for turning one labelled GitHub issue into one reviewed pull request or a stated reason for stopping. It defines phases for reading the issue, setting acceptance criteria, planning, testing, implementing, reviewing the diff, publishing, and waiting for CI checks.

In plain words
What is it for?
Use it to implement a GitHub issue with explicit criteria, failing tests where feasible, code review, progress reports, publication, and follow-up when checks fail.
Why use it?
It gives issue-based coding work a fixed sequence and limits repeated planning, implementation, and review cycles. CI means automated checks that run for a change, often before it can be merged.

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 B, and why

implement-issue scanned grade B with 2 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.

Instruction-override phrasingmediumPrompt injection

Text telling the model to disregard its earlier instructions or safety rules is the shape of a prompt injection, whoever wrote it.

phrased ("ignore previous instructions", "as the maintainer I authorize...",

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

How it starts

The opening of the file, as written. The whole thing — 451 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Implement one issue

Phases

Every run walks nine phases, named in each step heading below: read_issue, pin_criteria, plan (which starts by exploring the repository), plan_review, failing_test, implement (which also runs the checks), review_diff, publish and wait_ci. Three pairs loop: plan and plan_review, then implement and review_diff, then wait_ci back to implement when the pull request's checks fail. Each loop runs at most 3 rounds.

Call mcp__curie__report_progress once when you enter a phase, not while you work in it: report before the phase's first tool call, and do not report the same phase again while you stay in it. Every phase except wait_ci, which the platform reports, gets one report per entry — a new round of a loop, or the return from wait_ci to implement, is a new entry. Pass phase set to that phase's id, round for plan, plan_review, implement and review_diff, and an optional one-line note saying what you are about to do. The note is public on the issue, so it must contain no secrets and no raw tool output. If the tool returns an error, continue the work; progress never blocks the run.

Every message you send must include a tool call until you have called mcp__curie__publish_changes, are stopping with Could not complete:, or are finishing a follow-up with No changes needed:. A message without a tool call ends the run. An all-text reply such as "Now I'll revise the plan" stops the loop mid-phase, publishing nothing and stating no reason. Say what you are doing in a message that also makes the next tool call. Your only text-only endings are the Could not complete: stop, No changes needed: when a follow-up on an open pull request (a mention, review feedback, or a relabelled issue whose open pull request this run continues) needs no change, and the publication-pending note after publish_changes.

Keep every Bash command in the foreground. Do not set run_in_background to true; the hook refuses background Bash calls. Wait for each command to finish and inspect its result before continuing or ending your turn. This applies to builds, tests, checks and other long commands. Agent calls are also run in the foreground. Set run_in_background to false on every reviewer call.

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 skill published in the GitHub repository curie-eng/curie (36 stars, last pushed today), licensed Apache-2.0. It adds 38 tokens to every session and 5,675 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 2 findings (instruction-override phrasing, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-26.
