Comprehensive project planning and documentation generator for software projects.

  • Works in 7 steps: Project Architect Role Definition → Initial Project Understanding → Deliverable Definition (Set Upfront) → …

  • Runs Python scripts from its folder

What it does

Project Planner is an agent skill from adrianpuiu/claude-skills-marketplace. Comprehensive project planning and documentation generator for software projects. Creates structured requirements documents, system design documents, and task breakdown plans with implementation tracking. Use when starting a new project, defining specifications, creating technical designs, or breaking down complex systems into implementable tasks. Supports user story format, acceptance criteria, component design, API specifications, and hierarchical task decomposition with requirement traceability.

Its SKILL.md is about 6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including scripts, reference files and assets (for example `README.md`, `assets/requirements-template.md` and `plugin.json`).

It sits in Product & Project Management, covering Task breakdown, User stories and PRD writing. The repository describes itself as: A comprehensive skill that establishes Claude as a Project Architect to generate detailed planning documents that serve as blueprints for AI-assisted software development.

When your agent uses it

  • Starting a new project
  • Defining specifications
  • Creating technical designs
  • Breaking down complex systems into implementable tasks

Example prompts

  • “/project-planner”

Requirements

  • Python 3
  • Docker

Workflow steps

7 steps, taken from the step headings in SKILL.md.

  1. Project Architect Role Definition
  2. Initial Project Understanding
  3. Deliverable Definition (Set Upfront)
  4. Generate Requirements Document
  5. Generate Design Document
  6. Generate Implementation Plan
  7. [Component Name]

What it can do on your machine

Read from SKILL.md and the folder at commit 4e313a6. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 2 files in scripts/ (Python), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Project Planner loads about 6k tokens when it runs, and up to ~17k if it reads all its reference files. Until then it costs about 130 tokens; SKILL.md has 1,218 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~130
When it runs · the whole SKILL.md, loaded when a task matches
~6k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~17k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,218 words (~6,035 tokens).

“This skill provides templates and guidance for generating comprehensive project planning documents that serve as blueprints for AI-assisted implementation.”
