task-breakdown

task-breakdown is a skill for Claude Code from centminmod/my-claude-code-setup. It costs 177 tokens per session (2,427 once invoked), scanned A, original, MIT.

A session-analysis tool that groups individual coding-agent requests into the larger tasks they were part of, such as adding authentication or fixing a cache problem. It creates a companion page showing each task and its value verdict.

In plain words
What is it for?
Use it to review an agent session, understand which requests belonged to the same task, and identify work that was worthwhile, mixed, or likely wasted.
Why use it?
A request-by-request log can hide the actual work you were trying to complete. This groups related requests while keeping cost, turn, token, and waste figures tied to the exported session data.

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

task-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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 183 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Task Breakdown

Turns a session's per-request breakdown (the deterministic request_units emitted by session-metrics) into semantic tasks the user actually thinks in — "added auth", "debugged the cache miss" — and labels each with a verdict. You do the one thing deterministic code can't: decide which requests belong to the same task. The script does everything else (cost, turns, tokens, waste signals, the themed page).

Model. This skill runs on your session's current model. It no longer pins one (a hard model: pin ran the inline turn on that model, dragging the whole conversation into that model's context window — on a long session that overflowed and broke invocation). The grouping + verdict work is judgement-heavy, so it wants a capable model; for a cheaper run that's still strong enough, /model sonnet before invoking. Don't drop to Haiku — the semantic verdicts need the headroom.

Division of labour — do not blur it:

  • The export owns the numbers. Every cost / turn / token / waste figure comes from request_units in the JSON export. You MUST NOT sum money or invent figures — --render-tasks recomputes all totals from the export.
  • You own the grouping + labels only. You assign each request_unit_id to a task, write a short title, a verdict, and a one-line rationale.

Inputs

$ARGUMENTS[0] (optional) = path to a session-metrics JSON export, e.g. exports/session-metrics/session_<id8>_<ts>.json (session scope is the primary target; project_*.json also works — units carry a session_id). The export must contain a request_units array.

If $ARGUMENTS[0] is missing, first generate a session export by invoking the session-metrics skill (or run its script) for the session of interest with --output json html, then use the written session_*.json path.

Steps

  1. Locate the export and the renderer.
    • Export: $ARGUMENTS[0], or the JSON you just generated.
    • Renderer: the sibling session-metrics skill's script. Resolve its path (it ships in the same plugin):
      • plugin install: ../session-metrics/scripts/session-metrics.py
      • dev repo: .claude/skills/session-metrics/scripts/session-metrics.py Use whichever exists (glob if unsure).

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.
