github-issue-format

github-issue-format is a skill for Claude Code, Codex from richkuo/rk-skills. It costs 51 tokens per session (777 once invoked), scanned A, original, MIT.

A required writing format for GitHub issues, including a complexity line, a complete problem description, acceptance criteria, a plain-English section, and attribution. GitHub issues are records used to track software problems and planned work.

In plain words
What is it for?
Use it before creating or editing GitHub issues so titles, complexity information, goals, acceptance criteria, and plain-English explanations are included.
Why use it?
Inconsistent or incomplete issues make work harder to understand, estimate, and review. This sets a shared structure that every issue must follow.

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

github-issue-format 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

GitHub issue format

  • Never create a placeholder, stub, or empty-bodied issue. Every issue gets a complete body at creation — complexity rationale line, concrete problem statement, goal, approach/acceptance criteria, ## Plain simple English — even in a batch. If a follow-up isn't ready to spec, track it in the parent issue or notes until it is.
  • Title format: [C<score>] <title> — a clear plain-simple-English sentence in ASD-STE100, precise about component and behavior, e.g. [C95] Orders can be filled twice when two fills arrive at the same moment.
  • Complexity score (0–100) is a model + effort routing signal. It is not a time estimate. Load the canonical formula, axes, and routing table from validate-issue step 6; do not restate or approximate them here.
  • First line of the body is a one-line rationale matching the title prefix, ending with an explicit fableplan signal: **Complexity: 95/100** — Capability 3 (Risk 4 — money/data-integrity on order-fill path); Volume 20 — Opus 5, xhigh · fableplan: yes (Fable 5 never pairs with xhigh; the LLM Attribution Footer section of CLAUDE.md owns the Fable effort ceiling. xhigh is legal only on Opus/Sonnet-class builds.)
  • fableplan signal: · fableplan: yes when the score is ≥ 71 (a Fable 5 plan is posted before the build; the builder is Opus 5 at both plan bands: high at 71–80, xhigh at 81+); scores below 71 are · fableplan: no (they don't need a separate plan). Always write it explicitly — absence is ambiguous, not "no".
  • Body section order: complexity rationale line, ## Problem, ## Goal, ## Approach, ## Acceptance criteria, ## Plain simple English, then any Execution block, then the attribution footer. Plain simple English is the last prose section a human reads; an Execution block is machine metadata and keeps its place between that section and the footer.
  • ## Plain simple English is mandatory on every issue. One short paragraph under 55 words in ASD-STE100 (Simplified Technical English) per the CLAUDE.md/AGENTS.md Response Style rules. State what is wrong or missing and why it matters, so a reader who knows the product but not the code understands the issue without reading the technical sections. Never restate the approach there, never list file paths or symbols, and never put a time or effort estimate in it. An edit that rewrites body prose adds the section when it is missing; an edit that changes only machine metadata (the Execution block, or the [C<score>] title prefix) leaves every prose section unchanged and does not add it.
  • End the body with the LLM Attribution FooterCreated for a new issue, Validated when a validation pass produced the edit (validate-issue and its wrappers), Updated for any other edit. Stack the new line under the existing ones; never replace them, and never append a line that exactly duplicates one already there.
  • Project precedence: a repo CLAUDE.md issue/footer format overrides this default.

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.
