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 5.1 | $0.00296 | $0.00296 |
| Opus 5.5 | $0.00118 | $0.00118 |
| Sonnet 5.5 | $0.00059 | $0.00059 |
| Haiku 4.5 | $0.00030 | $0.00030 |
Grade A, and why
implement-task 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 1mo 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
Implement Task
Approach task implementation methodically with careful planning and execution.
Process:
1. Think Through Strategy
- Understand the complete requirement
- Identify key components needed
- Consider dependencies and constraints
- Plan the implementation approach
2. Evaluate Approaches
- List possible implementation strategies
- Compare pros and cons of each
- Consider:
- Performance implications
- Maintainability
- Scalability
- Code reusability
- Testing complexity
3. Consider Tradeoffs
- Short-term vs long-term benefits
- Complexity vs simplicity
- Performance vs readability
- Flexibility vs focused solution
- Time to implement vs perfect solution
4. Implementation Steps
- Break down into subtasks
- Start with core functionality
- Implement incrementally
- Test each component
- Integrate components
- Add error handling
- Optimize if needed
- Document decisions
5. Best Practices
- Write tests first (TDD approach)
- Keep functions small and focused
- Use meaningful names
- Comment complex logic
- Handle edge cases
- Consider future maintenance
Checklist:
- Requirements fully understood
- Approach documented
- Tests written
- Code implemented
- Edge cases handled
- Documentation updated
- Code reviewed
- Performance acceptable
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.

implement-task is a cursor rule published in the GitHub repository steipete/agent-rules (5,677 stars, last pushed 5mo ago), licensed MIT. It adds 296 tokens to every session, about $0.0012 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 2026-08-30.
