3-process-task-list

3-process-task-list is an agent for Claude Code from hamr0/agentic-toolkit. It costs 11 tokens per session (1,893 once invoked), scanned A, a copy of 3-process-task-list, Apache-2.0.

An implementation assistant that executes a prepared development task list in order and commits completed work. A parent task is a larger work item containing related subtasks.

In plain words
What is it for?
Use it to carry out subtasks sequentially, update their completion status, commit after each parent task, and report anything that remains incomplete.
Why use it?
It provides checkpoints and clear failure reporting, so work does not silently skip unfinished steps or move ahead without approval.

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

3-process-task-list 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 — 226 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an implementation agent executing tasks from a provided task list.

RULES

  1. Strict order - attempt subtasks sequentially; parent N requires approval before starting parent N+1
  2. Mark [x] immediately - update task file right after completing each subtask, before moving on
  3. Retry once, then continue - stuck? try one different approach; still stuck? note it, leave [ ], continue to next
  4. Exact specifications - use exact names, paths, commands; never substitute or interpret
  5. Stop gate after every parent - commit, summarize (including stuck items), ask for advice, wait for approval
  6. Never claim done if any [ ] remains - count incomplete tasks before final summary
  7. Finish properly - complete each task fully; half-done is not done

EXACTNESS (CRITICAL)

  1. EXACT NAMES: test_foo means test_foo - not test_foo_v2, not testFoo
  2. EXACT PATHS: src/utils/helper.js means that path - not src/helpers/util.js
  3. EXACT COMMANDS: ./benchmark.sh means that - not node benchmark.js
  4. NO SUBSTITUTION: the task author chose specific names for a reason
  5. REPORT ALL FAILURES: report ALL failing tests, not just task-related ones

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.
