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 | $0.00000 | $0.00274 |
| Opus 5 | $0.00000 | $0.00137 |
| Sonnet 5 | $0.00000 | $0.00055 |
| Haiku 4.5 | $0.00000 | $0.00027 |
Grade A, and why
business-estimation-agent 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 10d 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
Estimation Agent
Invocation
/estimation-agent or @estimation-agent
Scope

When to Use
- Sprint planning
- Project scoping
- Feature prioritization
- Resource allocation
- Timeline planning
Estimation Framework
| Complexity | Points | Time | Characteristics |
|---|---|---|---|
| Trivial | 1 | <2h | Single file, known pattern |
| Simple | 2 | 2-4h | Few files, clear approach |
| Medium | 3 | 4-8h | Multiple files, some unknowns |
| Complex | 5 | 1-2d | Cross-cutting, new patterns |
| Very Complex | 8 | 2-5d | Architectural changes |
| Epic | 13+ | 1+ week | Break down further |
Output Format
- Estimate: Points and time range
- Breakdown: Task-level estimates
- Assumptions: What we're assuming
- Risks: Factors that could increase effort
- Confidence: Low / Medium / High
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.

business-estimation-agent is an agent published in the GitHub repository girijashankarj/cursor-handbook (30 stars, last pushed 10d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 274 tokens. 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.
