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 | $0.00083 | $0.00316 |
| Opus 5 | $0.00042 | $0.00158 |
| Sonnet 5 | $0.00017 | $0.00063 |
| Haiku 4.5 | $0.00008 | $0.00032 |
Grade A, and why
estimate 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 2d 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
Sipcode — Estimate (pre-flight cost prediction)
Call the sipcode:estimate_task_cost MCP tool with:
task: natural-language task description (≥3 chars). Example:"refactor the auth pipeline across 6 files".cwd: absolute path to the project root the task will run in. If the user didn't specify a directory, ask before calling.
The tool returns per-model dollar predictions with a confidence band.
When presenting:
- Show all three models (Opus / Sonnet / Haiku) side-by-side, not just the most expensive.
- Surface the confidence band — if it's wide, say so honestly. If the tool reports
confidence: "low"because no past sessions matched this complexity tier, mention that the estimate is heuristic-only. - Make a model recommendation grounded in the cost spread. If Haiku is within ~10% of Sonnet for the task, recommend Haiku. If the task complexity is high (5+ files), Opus is usually worth the cost.
- Never invent precision. Round to whole cents unless the estimate is sub-$0.10.
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.

estimate is a skill published in the GitHub repository Anuj7411/sipcode (46 stars, last pushed 1mo ago), licensed MIT. It adds 83 tokens to every session and 316 once invoked, about $0.0004 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.
