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.

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 | $0.00152 | $0.04885 |
| Opus 5 | $0.00076 | $0.02442 |
| Sonnet 5 | $0.00030 | $0.00977 |
| Haiku 4.5 | $0.00015 | $0.00488 |
Grade A, and why
content-brief-authoring 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 10d 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.

Content Brief Authoring
A senior content strategist's playbook for authoring per-piece content briefs that actually guide writers to produce content worth publishing.
Most content briefs are some flavor of broken. The thin version is a keyword, a word count, and a deadline; the writer fills in everything else from scratch and the output is generic. The thick version is a 4-page document nobody reads, that the writer skims for the headline and the outline and ignores the rest. Either way, the brief failed at its job: making the writer's work easier and the output more predictable.
This skill is the middle path. It defines the 12 fields that earn their keep in a content brief, the fields that bloat without helping, and the discipline of writing briefs that route a writer (human or AI) toward a content piece that ranks for its target keyword, gets cited by AI engines, converts the right reader, or whatever the success criteria say. It assumes you have decided what to write (see content-strategy for program-level decisions) and now you are briefing each piece. The piece itself gets written separately (see content-and-copy).
When to use this skill: briefing a writer (human or AI) on an individual content piece, auditing existing briefs that are not producing good content, building a brief template for a content program, or running a brief-generation pipeline through Frase, AirOps, or another tool.
What this skill is for
This skill spans the per-piece editorial brief discipline. It composes with three sister skills, and the distinction between them is what keeps each one sharp.
creative-briefis a project brief. It bridges discovery to execution at the project level: a new website, app, brand, or campaign. Audience, goals, scope, success at project scope.content-strategyis a program-level editorial strategy. Pillars, calendar, topic clusters, governance. What to produce across a quarter or a year.content-and-copyis the writing itself. Voice, structure, edit pass, tone calibration. Execution scope for general editorial.- This skill is the per-piece brief between
content-strategy(program decided) andcontent-and-copy(piece gets written). It briefs a single content artifact: keyword, intent, audience, outline, entities, success criteria.

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.
