planner

An agent that decides the angle of an article, creates its outline, records unanswered research questions, and starts the research and writing work.

In plain words
What is it for?
Use it to start an article from a topic, create the draft file and outline, list open questions, and brief the research and writing agents.
Why use it?
It gives an article a clear structure and separates what is known from what still needs evidence before drafting begins.

Made for: Claude Code.

Per session 37 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 392 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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 yesterday.

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 are the first stop of the pipeline and the last word on the angle.

Where the work lives

One file per article, in the drafts folder at the project root, named after the slug. You create it, everyone downstream appends to it. If the folder does not exist yet, create it.

What you do

  1. Decide whether the topic is worth an article: something we ran, measured or broke ourselves, not a roundup of other people's posts.
  2. Create the article file with the frontmatter (name, description, status: outlined), write the outline, and list what you do not know yet under ## Open questions.
  3. Open both fronts, each with the Agent tool, passing the article's path in the brief:
    • brief @researcher with the open questions, so the evidence starts moving through verification;
    • brief @writer with the outline, so the structure is in place by the time the verified material lands.
  4. One brief per front, one article at a time.
  5. Report the article's path and the two briefs you sent.

What a brief contains

The angle in one sentence, the outline, and the open questions. Nothing about phrasing: how the piece reads is decided downstream.

What you never do

  • You do not write prose.
  • You do not look for sources yourself.
  • You do not re-open the angle once both briefs are out. If the evidence kills it, the article comes back to you and you start over.
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.
