Asynkron.JsEngine: Command for Claude Code

.claude/skills/breakdown-issues/commands/breakdown-issues.md

breakdown-issues is a command for Claude Code from asynkron/Asynkron.JsEngine. It costs 12 tokens per session (1,301 once invoked), scanned A, original, MIT.

A GitHub issue breakdown tool that splits large tasks into smaller sub-tasks, repeating the process until each remaining task is ready to do or needs investigation.

In plain words
What is it for?
Use it to create and label hierarchical GitHub sub-tasks, including research tasks for work that needs investigation first.
Why use it?
It turns broad or unclear issues into a structured work plan and avoids stopping with tasks that are still too large to act on.

Command for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: names the TodoWrite tool.

This is asynkron/Asynkron.JsEngine's own configuration. It tells Claude Code how to work on Asynkron.JsEngine itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Asynkron.JsEngine configures →

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-issues 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 14d 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.

Issue Breakdown Skill

Break down GitHub issues recursively until all leaf tasks are either simple (actionable) or research (need investigation).

Complexity Labels

The following complexity labels must exist in the repository:

  • simple - Task completable in a focused coding session (1-2 hours)
  • moderate - Task requires multiple steps but is well-understood
  • complex - Task requires significant effort or has many sub-components
  • research - Task needs investigation before it can be broken down

Rules

  1. Stop conditions - Stop breaking down when a task is:

    • Labeled simple (actionable in one session)
    • Labeled research (needs investigation first)
    • Already has 2+ child issues
  2. Keep breaking down when a task is:

    • moderate or complex AND
    • Has 0-1 child issues
  3. No AI slop - Sub-tasks must be:

    • Clear, actionable work items
    • Sum of children = parent functionality
    • Follow naming conventions (e.g., "Task 1.2.3: Do something")
  4. Hierarchical naming:

    • Parent: "Task 1: Main work"
    • Children: "Task 1.1: Sub-work", "Task 1.2: Other sub-work"
    • Grandchildren: "Task 1.1.1: Detailed work"
  5. Mark as research when:

    • Root cause is unknown
    • Multiple competing approaches with no clear winner
    • You lack context to make informed breakdown decisions
  6. CRITICAL: Trackable Relationships:

    • Parent issues MUST have a task list with checkbox references to children
    • This creates a real GitHub relationship that tracks progress
    • When children are closed, the parent shows completion percentage
    • Just mentioning "Parent: #123" in the child body is NOT enough

Process

Step 1: Scan Open Issues

gh issue list --state open --limit 100 --json number,title,labels

Step 2: Identify Issues Needing Breakdown

For each issue, check:

  • Is it moderate or complex?
  • Does it have 0-1 children?
  • Is it NOT simple or research?

If all true → needs breakdown.

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.

breakdown-issues is a command published in the GitHub repository asynkron/Asynkron.JsEngine (11 stars, last pushed 3mo ago), licensed MIT. It adds 12 tokens to every session and 1,301 once invoked, about $0.0000 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 2026-10-02.
