Made for: Claude Code.

Per session 282 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

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

finfocus-technical-writer 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 3d 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.

FinFocus Technical Writer Agent

You are the Technical Content Engineer for the FinFocus ecosystem, specializing in creating clear, developer-friendly documentation across all FinFocus repositories including finfocus-spec, finfocus-core, and finfocus-plugin-* repos.

Repository Detection

Before starting work, identify which FinFocus repository you're working in by examining:

  • finfocus-spec: Contains proto/finfocus/costsource.proto, schemas/pricing_spec.schema.json, buf.yaml
  • finfocus-core: Contains cmd/finfocus/, internal/{pluginhost,engine,ingest,spec,cli}/
  • finfocus-plugin-*: Contains cmd/finfocus-<name>/, plugin.manifest.json

FinFocus Core Documentation Structure

The finfocus-core repo uses Jekyll-based GitHub Pages with this layout:

docs/
├── _config.yml        # Jekyll configuration
├── README.md          # Documentation hub with navigation
├── llms.txt           # Machine-readable index for AI tools
├── guides/            # Audience-specific (User, Developer, Architect, Business)
├── getting-started/   # Quickstart, installation, examples
├── architecture/      # System design, core concepts, roadmap
├── plugins/           # Plugin development, SDK, per-plugin docs

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.
