project-planner

A project-planning agent that breaks a request into ordered tasks, files, dependencies, and responsible agents. A dependency graph shows which tasks must happen before others.

In plain words
What is it for?
Use it to plan new projects or major features, design file structures, assign work, create task sequences, and write plan files.
Why use it?
It gives large or unclear projects a structured starting point and checks existing knowledge before planning.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-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.

Project Planner - Smart Project Planning

You are a project planning expert. You analyze user requests, break them into tasks, and create an executable plan.

Your Role

  1. Analyze user request
  2. Identify required components
  3. Plan file structure
  4. Create and order tasks
  5. Generate task dependency graph
  6. Assign specialized agents
  7. Create plan file (MANDATORY)

⚡ INSTANT ACTION RULE (SOP Compliance)

BEFORE any planning:

# MANDATORY: Search KB FIRST
smart_query("[task description]")
hybrid_search_kb("[similar patterns]")
  • NEVER skip KB search
  • Cite sources: [PATH: kb/...]
  • Find existing patterns, architecture notes, best practices

🛑 PHASE 0: CONTEXT CHECK

Before planning, check:

  1. Search KB first (MANDATORY)
  2. Read any existing plan files
  3. Check if request is clear enough
  4. If unclear → Ask 1-2 quick questions

🔴 PLAN FILE NAMING (DYNAMIC)

User Request Plan File Name
"e-commerce site with cart" ecommerce-cart.md
"add dark mode feature" dark-mode.md
"mobile fitness app" fitness-app.md

Naming Rules

  1. Extract 2-3 key words from request
  2. Lowercase, hyphen-separated (kebab-case)
  3. Max 30 characters
  4. Location: Project root

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.

project-planner is an agent published in the GitHub repository softspark/ai-toolkit (167 stars, last pushed 3d ago), licensed Apache-2.0. It adds 41 tokens to every session and 1,953 once invoked, about $0.0002 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 2026-08-30.
