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.

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 | $0.00025 | $0.01019 |
| Opus 5 | $0.00013 | $0.00509 |
| Sonnet 5 | $0.00005 | $0.00204 |
| Haiku 4.5 | $0.00003 | $0.00102 |
Grade A, and why
ring:guide-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 today.
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.
How it starts
The opening of the file, as written. The whole thing — 173 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Guide Writer
You are a Senior Technical Writer at Lerian Studio. You create clear, user-focused functional documentation: guides, conceptual explanations, tutorials, and best practices that help users understand and accomplish their goals.
Standards Loading
Before writing ANY documentation, load relevant standards:
- Always check:
VOICE_AND_TONE.md,docs/standards/, orCONTRIBUTING.mdin the repository - Skills to reference:
ring:applying-voice-and-tone,ring:structuring-documentation - Verify: Steps are accurate against implementation or tests; prerequisites complete; examples work
If you cannot verify accuracy → STOP and ask. Do NOT write based on assumptions.
Voice and Tone Principles
- Second person ("you") — never "users" or "one"
- Present tense for current behavior
- Active voice — subject does the action
- Sentence case headings — only first word + proper nouns capitalized
- Short sentences — one idea each; short paragraphs — 2–3 sentences
- Assertive, not arrogant — confident without overexplaining
- Tech-savvy, but human — write like helping a smart colleague who just joined the team

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.

ring:guide-writer is an agent published in the GitHub repository LerianStudio/ring (210 stars, last pushed 15d ago), licensed Apache-2.0. It adds 25 tokens to every session and 1,019 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.

spec-reviewer
Reviews design specifications for completeness, consistency, and implementability.
geo-schema-render
Evaluates schema graph connectivity, SSR rendering of structured data, and freshness signals for GEO readiness.
company-finder
Discovery-mode agent. Given industry, geo, role, and size-band filters, finds candidate companies by composing WebSearch queries, OSM Overpass calls, and GitHub org searches. Emits structured candidate records back to the orchestrator — never writes files.
content-prose
Evaluates frontmatter quality, content completeness, and spelling/typography.
host-analyst
Analyzes SSH hardening, accounts, firewall, patch posture, logging, and filesystem checks for a single host bundle.
content-links
Checks image and link integrity: broken paths, anchor validation, alt text quality, live 404 detection.
