project-planning

project-planning is a skill for Claude Code from athola/claude-night-market. It costs 28 tokens per session (1,017 once invoked), scanned A, original, MIT.

A planning tool that turns a software specification into ordered implementation tasks, including dependencies between tasks and component interfaces.

In plain words
What is it for?
Use it to design system structure, divide work into tasks, plan sprints, and prepare a project for implementation.
Why use it?
It removes the work of breaking broad requirements into a buildable sequence. It also helps identify what must be designed or completed first.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.
    Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.
  • medium Excessive Agency · line 94
    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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

project-planning 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 8d 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.

Delegation

For detailed task planning workflows, this skill delegates to spec-kit:task-planning as the canonical implementation. Use this skill for quick planning needs; use spec-kit for thorough project plans.

When To Use

  • After specification phase completes
  • Need to design system architecture
  • Need task breakdown for implementation
  • Planning sprints and resource allocation
  • Converting requirements into concrete tasks
  • Defining component interfaces and dependencies

When NOT To Use

  • No specification exists yet (use Skill(attune:project-specification) first)
  • Still exploring problem space (use Skill(attune:project-brainstorming) instead)
  • Ready to execute existing plan (use Skill(attune:project-execution) instead)
  • Need to adjust running project (update plan incrementally, don't restart)

Integration

With superpowers:

  • Uses Skill(superpowers:writing-plans) for structured planning
  • Applies checkpoint-based execution patterns
  • Uses dependency analysis framework

Without superpowers:

  • Standalone planning methodology
  • Task breakdown templates
  • Dependency tracking patterns

Quality Checks

Before completing plan:

  • ✅ All architecture components documented
  • ✅ File Structure section present before tasks
  • ✅ All task files appear in File Structure table
  • ✅ All FRs mapped to tasks
  • ✅ All tasks have acceptance criteria
  • ✅ Dependencies are acyclic
  • ✅ Effort estimates provided
  • ✅ Critical path identified
  • ✅ Risks assessed with mitigations
  • ✅ Sprints balanced by capacity

Record the Tradeoff (decision journal)

Planning is where architecture and scope decisions get made: the pattern chosen, the dependency accepted, the work deferred. Record each decision that had real alternatives to docs/tradeoffs.md (draft and confirm):

  • If leyline is installed, invoke Skill(leyline:decision-journal) and append a tradeoff entry (the decision, the options weighed, and what was sacrificed; set phase to plan). Show the draft; append on confirmation.
  • Fallback (leyline absent): append to docs/tradeoffs.md using the in-file ENTRY TEMPLATE; assign the next TR-NNN id.

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.

project-planning is a skill published in the GitHub repository athola/claude-night-market (337 stars, last pushed yesterday), licensed MIT. It adds 28 tokens to every session and 1,017 once invoked, about $0.0001 per session on Opus 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 2026-09-03.
