task-planner

task-planner is a skill for Claude Code, Codex from ahmadulhoq/agentskel. It costs 30 tokens per session (532 once invoked), scanned A, original, MIT.

A planning guide for breaking a feature or specification into clear, workable subtasks. It also covers estimating effort, tracking progress, and coordinating multi-step work.

In plain words
What is it for?
Use it to create implementation plans, split complex work into smaller tasks, record progress, and review the results.
Why use it?
It reduces confusion about what needs to happen, what depends on what, and whether the work is complete.

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-planner 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 2d 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.

Task Planner Standards

Task Management

  1. Plan First: Write plan with checkable items before starting.
  2. Verify Plan: Check in with the user before executing.
  3. Track Progress: Mark items complete as you go.
  4. Explain Changes: High-level summary at each step.
  5. Document Results: Add review section when complete.
  6. Capture Lessons: Update .memory/LESSONS.md after corrections.

Task Quality

  • Tasks must be clear, specific, and actionable.
  • Complex tasks must be broken into atomic, trackable subtasks.
  • Dependencies between tasks must be explicitly declared.
  • Security-related tasks must undergo mandatory review.
  • Escalate ambiguous or contradictory tasks for clarification.

Blueprint Check (if configured)

If Blueprint Path is set in .memory/CONFIG.md and the task involves shared business logic:

  • Read the relevant spec(s) in [BLUEPRINT_PATH]/specs/ before planning.
  • Check [BLUEPRINT_PATH]/parity/PARITY_MATRIX.md for current platform status.
  • Include in the plan: "Requires Knowledge Bus entry" if the change affects cross-platform contracts.
  • Note any spec gaps — if the spec is missing or incomplete, plan a spec update as part of the task.

Skip this section if no blueprint is configured or the task is project-specific.

Change Tracking

  • All rule or config changes must be documented in CHANGELOG.md.
  • Record source, timestamp, and rationale when modifying shared assets.
  • A rollback plan must be defined for every major change.

Subagent Strategy

When a task benefits from fresh context, parallel execution, or isolated scope, use the subagent-dispatch skill. It provides prompt templates for implementer, reviewer, and researcher subagents with explicit scope boundaries and result validation.

When to dispatch:

  • Subtasks are independent and can proceed in parallel
  • Parallel execution provides meaningful time savings
  • Fresh context helps (no accumulated conversation noise)
  • Scope of each subtask is clear and self-contained

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.
