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 | $0.00036 | $0.00498 |
| Opus 5.5 | $0.00014 | $0.00199 |
| Sonnet 5.5 | $0.00007 | $0.00100 |
| Haiku 4.5 | $0.00004 | $0.00050 |
Grade A, and why
start-dev 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 2mo 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.
What it actually says
Start Development Skill
This skill is automatically triggered when the user says "开始", "开始开发", "继续", or "start".
Behavior
When triggered, this skill will:
- Read TODO.md - Load the current task list
- Check Project Memory - Review
.claude-memory/context.jsonfor historical context - Review Module Registry - Check
docs/modules/REGISTRY.mdto avoid duplication - Check Known Issues - Review
docs/troubleshooting/KNOWN_ISSUES.md - Identify Next Task - Find the first uncompleted task in TODO.md
- Start Implementation - Begin working on the task
- Run Tests - Ensure 100% coverage after changes
- Update Documentation - Update module registry and API docs
- Record Progress - Update project memory
Workflow
User says "开始"
↓
Read TODO.md
↓
Check .claude-memory/context.json
↓
Review docs/modules/REGISTRY.md
↓
Find next uncompleted task
↓
Implement task
↓
Run tests (pytest --cov --cov-fail-under=100)
↓
Update documentation
↓
Update project memory
↓
Ask user: "Task completed. Continue to next task?"
Example
User: "开始"
Claude:
Reading TODO.md...
Current phase: Phase 1 - Core Infrastructure
Next task: Setup Python environment (pyproject.toml, requirements.txt)
Checking project memory...
No previous context found. Starting fresh.
Checking module registry...
No modules implemented yet.
Starting implementation of: Setup Python environment
...
Implementation
This skill should:
- Be proactive and autonomous
- Follow the development workflow in CLAUDE.md
- Ensure 100% test coverage
- Update all relevant documentation
- Record decisions in project memory
- Ask for clarification 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.
- 2mo ago First seen · 83 lines · 36 tokens per session scan A 48b37780bafb
start-dev is a skill published in the GitHub repository yxhpy/openuser (2 stars, last pushed 8mo ago), licensed MIT. It adds 36 tokens to every session and 498 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-31.
