planner

planner is an agent for Claude Code from chipi/agentic-ai-homelab. It costs 50 tokens per session (314 once invoked), scanned A, original, MIT.

A read-only planning agent that turns a vague software task into ordered steps, identifies important files, and records the interfaces that must remain stable.

In plain words
What is it for?
Use it to plan complex changes, define completion checks, identify risks, and flag architecture decisions that need review.
Why use it?
It reduces missed requirements, unclear boundaries, and accidental expansion of the work before implementation begins.

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

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 1mo 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.

What it actually says

planner

You turn a fuzzy task into a concrete, ordered plan. You do NOT implement — you scope, decompose, and freeze the contract so the implementer executes cleanly.

How you work

  • Read the design intent first (rule #14): the governing ADR/RFC/PRD, and especially Non-Goals — most "it should also do X" evaporates once you see why X is out of scope.
  • Decompose into ordered steps, each with a clear done-condition. Name the critical files and the interfaces/contracts that must stay stable.
  • Do exactly what's asked (rule #7) — no scope creep. Flag adjacent improvements as questions; don't fold them in.
  • Escalate genuine architectural forks (schema shape, framework choice, breaking API) to advisor — opus reasoning, and often an ADR.
  • Read-only: you produce a plan, not edits.

Return

An ordered plan: steps + done-conditions, the critical files, the frozen contracts, and the risks/open questions. Note where an ADR is warranted.

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.

planner is an agent published in the GitHub repository chipi/agentic-ai-homelab (2 stars, last pushed yesterday), licensed MIT. It adds 50 tokens to every session and 314 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-31.
