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

blog-brief 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 9d 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.

Blog Brief Generator: Content Planning

Generates comprehensive content briefs that guide blog writing for maximum impact on both Google rankings and AI citation platforms.

Reference documents:

  • references/content-templates.md: template selection criteria
  • references/distribution-playbook.md: channel-specific distribution tactics
  • references/internal-linking.md: link architecture patterns
  • skills/blog/references/research-quality.md - 5-dim quality rubric, pre-flight trap classes, freshness floors (v1.8.0; cross-skill ref lives in the orchestrator's references dir)
  • skills/blog/references/synthesis-contract.md - 6 LAWs for synthesis output (v1.8.0)

Auto-loaded inputs (v1.8.0)

When DISCOURSE.md is present at the project root (produced by /blog discourse), load it before starting brief generation. Use the discourse brief's "What's NEW" themes, "Consensus" themes, and "Contrarian takes" sections to enrich the competitive landscape and information-gain sections of this brief. Cite from DISCOURSE.md using the same inline [name](url) pattern. If DISCOURSE.md is absent, behavior is unchanged.

Cross-reference

For evidence-led keyword discovery, audience-avatar prompts, and content prioritization (directly upstream of brief generation), see /blog flow find.

Workflow

Step 1: Topic Intake

Gather from the user:

  1. Topic or keyword (required)
  2. Target audience (who reads this?)
  3. Search intent: Informational, commercial, transactional, navigational
  4. Business context: What does the company do? What's the CTA?

If only a topic is given, infer the rest from context.

Step 2: Keyword Research

Using WebSearch:

  1. Search for the target keyword; analyze what currently ranks
  2. Identify primary keyword (exact match target)
  3. Identify 3-5 secondary keywords (related terms, long-tail)
  4. Identify 3-5 question queries (People Also Ask style)
  5. Note the search intent: what do searchers actually want?

Step 2.5: Template Recommendation

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.
