breakdown

breakdown is a command for Claude Code from ngocsangyem/MeowKit. It costs 28 tokens per session (641 once invoked), scanned A, original, MIT.

A command that turns a product specification, requirement document, or issue into refined user stories and an optional technical breakdown. It can also create Jira tickets after confirmation; Jira is a work-tracking system.

In plain words
What is it for?
Use it with a Confluence page, Jira item, GitHub issue, Linear ticket, file, or pasted PRD to prepare stories, optional tickets, and codebase-aware technical work.
Why use it?
It breaks broad requirements into smaller, actionable pieces while keeping the technical analysis separate from later implementation planning.

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

breakdown 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 4d 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.

/mk:breakdown — Spec to stories + optional tickets + tech breakdown

When to use

Use when you have a Confluence page, Jira epic, GitHub issue, Linear ticket, or pasted PRD and want: (1) refined user stories, (2) optional Jira tickets, (3) codebase-aware tech breakdown report. Stops before plan creation.

  • NOT for sprint capacity planning → mk:planning-engine
  • NOT for bulk ticket creation → mk:story-sizer --auto-create
  • NOT for implementation planning → /mk:plan
  • NOT for single-ticket analysis or RCA → mk:intake or mk:jira-analyst

Usage

/mk:breakdown <source> [--source confluence|jira|github|linear|paste] [--project <KEY>]
  • <source>: Confluence URL/page-id, Jira KEY, GitHub issue URL, Linear URL, file path, or omit when using --paste.
  • --source: Override auto-detection.
  • --project <KEY>: Required when Jira creation confirmed in Phase D. If absent at first Create, Phase D aborts; spec analysis is preserved; Phase E emits a re-run footer.

Idempotency: Same-day re-run overwrites breakdown-{YYMMDD}-{slug}.md. Tickets already in Jira remain — pick "Skip" for existing stories on re-run.

Purpose

Analyze a spec or issue source, derive user stories, optionally create Jira tickets, optionally run tech planning, and write a breakdown report.

Dispatch

Use task-specific skills instead of duplicating their procedures here:

  1. Source analysis
    • Confluence sources → mk:confluence-spec-analyst
    • Jira/GitHub/Linear/paste/file sources → mk:intake
  2. Story decomposition — extract story title, acceptance criteria, complexity hint, and open questions from the source analysis.
  3. Optional ticket creation — for each accepted story, use mk:jira-issue; require --project <KEY> before creating tickets.
  4. Optional tech breakdown — after tickets exist, use mk:planning-engine plan --tickets <keys>.
  5. Report write — save tasks/reports/breakdown-{YYMMDD}-{slug}.md or the active plan's research/ directory.

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.
