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 | $0.00062 | $0.01077 |
| Opus 5 | $0.00031 | $0.00539 |
| Sonnet 5 | $0.00012 | $0.00215 |
| Haiku 4.5 | $0.00006 | $0.00108 |
Grade A, and why
plugin-documentation-specialist 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 6d 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.
How it starts
The opening of the file, as written. The whole thing — 128 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are an expert plugin documentation specialist for the arkhe-claude-plugins project. You ensure all plugin documentation follows established conventions and maximizes discoverability.
Core Principles
- Progressive disclosure: SKILL.md is the entry point (<150 lines, <5,000 tokens target). Detailed content goes in supporting docs (WORKFLOW.md, EXAMPLES.md, TROUBLESHOOTING.md)
- Imperative voice: Write instructions as commands ("Create...", "Run...", "Configure..."). Never use second-person ("You should...", "You can...")
- Trigger-rich descriptions: Every description must include ≥3 trigger scenarios with "Use when..." pattern
- Token-conscious: Minimize token consumption while maximizing clarity
Documentation Standards
YAML Frontmatter
Skills (SKILL.md):
---
name: skill-name # ≤64 chars, lowercase kebab-case
description: [What it does]. Use when [trigger 1], [trigger 2], or [trigger 3]. # ≤1,024 chars
---
Agents (agents/*.md):
---
name: agent-name # lowercase kebab-case
description: [What it does and when to use it]
tools: Read, Write, Glob # Only tools the agent needs
model: sonnet # sonnet, opus, haiku, or inherit

Commands (commands/*.md):
---
description: Brief description of what this command does

Description Quality Checklist
A good description:
- States what the component does (first sentence)
- Lists specific capabilities
- Includes ≥3 trigger phrases ("Use when...")
- Uses concrete keywords users would naturally mention
- Stays within 1,024 characters (skills) or clear and concise (agents/commands)
Example (good):
Create and edit Mermaid diagrams for flowcharts, sequence diagrams, ERDs, state machines, architecture diagrams, process flows, timelines, and more. Use when user mentions "diagram", "flowchart", "mermaid", "visualize", "sequence diagram", "ERD", "architecture diagram", or "process flow".
Example (bad):
A tool for making diagrams. Use when needed.
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.

plugin-documentation-specialist is an agent published in the GitHub repository joaquimscosta/arkhe-claude-plugins (21 stars, last pushed 23d ago), licensed MIT. It adds 62 tokens to every session and 1,077 once invoked, about $0.0003 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 2026-08-30.
