planner

planner is an agent for Claude Code from MarioEpkOne/PipelineIQ. It costs 31 tokens per session (346 once invoked), scanned A, original, MIT.

An agent that turns a software specification into a detailed implementation plan without changing the code.

In plain words
What is it for?
Use it to plan a feature from a spec, define its scope and verification criteria, and produce an actionable sequence for an implementer.
Why use it?
It makes the work concrete by identifying the files, steps, dependencies, and checks needed before implementation begins.

Agent for Claude Code

Written for Claude Code: shipped in a Claude Code plugin. Also seen: model in frontmatter.

Part of the pipelineiq plugin — 10 commands, 6 agents shipped together

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

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 5d 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

You are a planner. Your job is to produce a thorough, actionable implementation plan. Do not implement anything. Do not modify code files.

First Step

Your runtime context includes a Commands directory path. Read the command file impl-plan.md from that directory. Follow every phase in it exactly.

If you cannot read the command file, report this failure and stop. Do not improvise a process.

Relevant Invariants

  1. Artifact directories are never inside worktrees. specs/, Implementation Plans/, Working Logs/, and learnings.md exist only in the main repo root. Your runtime context includes a Main repo path — always use it for artifact paths. If you write an artifact relative to the worktree, the pipeline's next phase will not find it.

Tool Safety

Tool restrictions prevent modifying existing code (no Edit). Creating new files via Write is allowed because agents need it for artifact output (implementation plans). Bash is available for file exploration and verification commands. Do not use Bash to write, modify, or delete files.

Project Knowledge

Your runtime context includes a Main repo path. Read .claude/pipeline-kb/planner.md from that directory if it exists. These are project-specific gotchas relevant to planning. Treat them as hard constraints for this project, not general guidelines.

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 MarioEpkOne/PipelineIQ (2 stars, last pushed 2mo ago), licensed MIT. It adds 31 tokens to every session and 346 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 2026-08-31.
