plan-issue

plan-issue is a skill for Claude Code from Jartan-LLC/grimoire. It costs 14 tokens per session (484 once invoked), scanned A, original, MIT.

A workflow for turning a GitHub issue—a tracked software task or bug report—into a step-by-step implementation plan.

In plain words
What is it for?
Use it to plan a feature or fix, assess its scope, and decide whether large work should be split into smaller issues.
Why use it?
It gathers the issue details, relevant documentation, and existing code patterns before work begins, reducing missed requirements and oversized changes.

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

plan-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 5d 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.

Plan Issue

Create an implementation plan for a GitHub issue.

Process

1. Load Issue

Determine the issue number from the user's request, which may carry context beyond the number. Fetch the issue details:

gh issue view <issue-number>

2. Read Relevant Docs

Based on the issue area, read the appropriate project documentation in docs/.

3. Explore Codebase

Find existing patterns similar to what the issue requires. Look at how comparable features are already implemented.

4. Assess Scope

Evaluate whether the issue should be broken into sub-issues. Not every multi-part feature needs splitting -- but large features degrade in quality when implemented in a single AI context. Consider splitting when:

  • The diff would be very large -- Thousands of lines in one pass means mistakes get buried. Smaller, focused issues produce better results.
  • There are genuinely separable concerns -- A reusable module that happens to be needed by this feature is worth its own issue. A small page that accompanies a backend feature is not.

If sub-issues are warranted, use /praxis:create-issue to file them, referencing the parent issue. Sub-issue branches are created from the parent feature branch and merged back into it, not directly to main.

5. Design Considerations

Before creating the plan, think through:

  • Flexibility -- Will this be used by other modules or downstream consumers? Design for maximum abstraction where reuse is likely, while keeping interfaces solid and well-defined.
  • Robustness -- Clear models, explicit types, proper error handling. Flexible internals, rigid contracts.
  • Future-proofing -- Consider how this might need to evolve without requiring breaking changes.
  • Simplicity -- Don't over-engineer, but don't paint yourself into a corner either.

6. Create Plan

Write a plan in .claude/workspace/ following the format in the gitwise:github-conventions skill (see plan-format.md).

7. Post Plan

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.

plan-issue is a skill published in the GitHub repository Jartan-LLC/grimoire (2 stars, last pushed yesterday), licensed MIT. It adds 14 tokens to every session and 484 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-31.
