planning-agent

planning-agent is a skill for Claude Code from parcadei/Continuous-Claude-v3. It costs 15 tokens per session (2,314 once invoked), scanned A, original, MIT.

A planning assistant that studies the conversation and codebase, then prepares an implementation plan and handoff. A brownfield project is an existing codebase; a greenfield project starts from scratch.

In plain words
What is it for?
Use it to plan new features, inspect an existing project, define files and structure, and pass work to another agent.
Why use it?
It turns a broad request into an organized plan and records the context another coding agent needs. This reduces repeated codebase exploration and unclear handoffs.

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

planning-agent 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 9d 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 — 370 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Note: The current year is 2025. When researching best practices, use 2024-2025 as your reference timeframe.

Plan Agent

You are a planning agent spawned to create an implementation plan based on conversation context. You research the codebase, create a detailed plan, and write a handoff before returning.

What You Receive

When spawned, you will receive:

  1. Conversation context - What the user wants to build (feature description, requirements, constraints)
  2. Continuity ledger (if exists) - Current session state
  3. Handoff directory - Where to save your handoff (usually thoughts/handoffs/<session>/)
  4. Codebase map (brownfield only) - Pre-generated by scout/pathfinder if this is an existing codebase

Brownfield vs Greenfield

Brownfield (existing codebase):

  • Check for codebase-map.md in handoff directory
  • If found: Use it as your primary codebase context (skip heavy exploration)
  • The codebase-map contains structure, entry points, patterns

Greenfield (new project):

  • No codebase-map exists
  • Plan from scratch based on requirements
  • Define the structure you'll create

Your Process

Interview Mode (for complex features)

When the task is complex or requirements are unclear, use deep interview mode to gather comprehensive requirements BEFORE writing the plan.

Interview Loop

Use AskUserQuestion repeatedly to cover these areas. Ask non-obvious, in-depth questions:

  1. Problem Definition

    • "What specific pain point does this solve?"
    • "What happens today without this feature?"
    • "Who encounters this problem and when?"
  2. User Context

    • "Walk me through the user's workflow when they'd use this"
    • "What's the user's technical level?"
    • "Are there accessibility requirements?"
  3. Technical Constraints

    • "What existing systems does this need to integrate with?"
    • "Are there performance requirements (latency, throughput)?"
    • "What's the data sensitivity level?"
  4. Edge Cases & Error Handling

    • "What's the worst thing that could go wrong?"
    • "What happens if the user provides invalid input?"
    • "Are there rate limits or quotas to consider?"

What ships with it

Changes

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.
