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

copy-editing 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.

The opening of the file, as written. The whole thing — 294 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Copy Editing

Systematically improve existing marketing copy through focused editing passes while preserving the core message.

Core Philosophy

Product context: If .agents/product-marketing-context.md exists (or .claude/product-marketing-context.md in older setups), read it first and tailor output to it; only ask for what it doesn't cover.

Editing is enhancing, not rewriting. Key principles: don't change the core message; multiple focused passes beat one unfocused review; every edit needs a clear reason; preserve the author's voice while improving clarity.


The Seven Sweeps Framework

Edit through seven sequential passes, one dimension each. After each sweep, loop back to check previous sweeps aren't compromised.

Sweep 1: Clarity

Focus: Can the reader understand what you're saying?

Check: confusing sentence structures, unclear pronoun references, jargon or insider language, ambiguous statements, missing context.

Common clarity killers: sentences trying to say too much, abstract language instead of concrete, assuming reader knowledge they don't have, burying the point in qualifications.

Process: Read through quickly, highlighting unclear parts without correcting yet. Then recommend specific edits and verify they maintain the original intent.

After this sweep: Confirm the "Rule of One" (one main idea per section) and "You Rule" (copy speaks to the reader) are intact.


Sweep 2: Voice and Tone

Focus: Is the copy consistent in how it sounds?

Check: shifts between formal and casual, inconsistent brand personality, jarring mood changes, word choices that don't match the brand.

Common voice issues: starting casual then becoming corporate, mixing "we" and "the company," unintentional humor/serious swings, technical language appearing randomly.

Process: Read aloud to hear inconsistencies, mark unexpected tone shifts, smooth transitions, keep personality throughout.

After this sweep: Return to Clarity to ensure voice edits didn't introduce confusion.

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.
