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 | $0.00811 | $0.00811 |
| Opus 5 | $0.00405 | $0.00405 |
| Sonnet 5 | $0.00162 | $0.00162 |
| Haiku 4.5 | $0.00081 | $0.00081 |
Grade A, and why
01coder-agent-skills CLAUDE.md 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 — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Plugin & Marketplace Architecture
This repo is a marketplace — a catalog of plugins that users add to Claude Code.
Key Concepts
- Marketplace = this repo. Users add it with
/plugin marketplace add sugarforever/01coder-agent-skills - Plugin = a group of related skills. Defined in
marketplace.jsonunderplugins[] - Skill = a
SKILL.mdfile that Claude auto-invokes based on context
marketplace.json Structure
All skills are bundled in a single plugin 01coder-skills. The plugin uses:
"source": "./"— plugin root is the repo root"skills": [...]— explicit list of all skill directory paths
{
"plugins": [
{
"name": "01coder-skills",
"source": "./",
"skills": [
"./skills/video-planner",
"./skills/share-reading"
]
}
]
}
This structure ensures that when the plugin is installed and cached, the skills/ directory hierarchy is preserved and Claude Code can discover the SKILL.md files.
Installation
/plugin marketplace add sugarforever/01coder-agent-skills
/plugin install 01coder-skills@01coder-agent-skills
New skills are picked up automatically on marketplace update — no reinstall 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.

01coder-agent-skills CLAUDE.md is an instructions file published in the GitHub repository sugarforever/01coder-agent-skills (133 stars, last pushed 2mo ago), licensed MIT.
