What is topic-outline?

A skill for creating and revising structured topic outlines from a brief, audience, angle, thesis, sections, questions, and sources. It is intended for editorial planning rather than a software task checklist.

Use it to plan or revise articles and other content topics, including their structure, supporting sources, open questions, and editorial direction.

It keeps an evolving content plan organized while preserving known information and separating unresolved decisions. It also records the next useful writing step and confidence level.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00028	$0.00326
Opus 5	$0.00014	$0.00163
Sonnet 5	$0.00006	$0.00065
Haiku 4.5	$0.00003	$0.00033

Security

Grade A, and why

topic-outline 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 13d 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

Topic Outline

Use this Skill when the user asks to plan, structure, or revise a content topic. Do not use it for a generic task checklist or for an outline the user did not request.

Call the current Tool catalog entry for com.homerail.topic-outline:upsert_topic_outline with the complete current outline. Its harness-safe wire name is supplied by the current turn and must not be guessed. Reuse one stable plugin-owned id such as com.homerail.topic-outline:current across turns so a revision replaces the same semantic node without colliding with Core or another plugin. A partial outline is valid: record what is known, preserve useful prior fields, and put only unresolved decisions in questions.

Keep the shape concise:

title names the topic, not the UI component.
brief, audience, angle, and thesis capture the current editorial direction.
outline contains ordered sections with short points and truthful status.
sources includes only real HTTP(S) references supplied or found through an authorized tool.
next_action states the next useful editorial step.
confidence reflects evidence, not presentation polish.

Use the matching topic-outline Tool only when it is listed for the current turn. Do not substitute a legacy dynamic widget. If the requested outline is not placed on the canvas, tell the user only that visible result and offer to retry.

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.
