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 | $0.02122 | $0.02122 |
| Opus 5.5 | $0.00849 | $0.00849 |
| Sonnet 5.5 | $0.00424 | $0.00424 |
| Haiku 4.5 | $0.00212 | $0.00212 |
Grade A, and why
pi-sdd-kit AGENTS.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 — 342 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
This repository contains @felipefontoura/pi-sdd-kit, a Pi package that provides skills and templates for a practical Specification-Driven Development workflow.
Repository Purpose
The package helps Pi users run an SDD workflow with explicit artifacts, human gates, traceability, and verification.
Additional study/reference repositories:
Use sdd-book as conceptual study material for how the SDD workflow should be explained and used.
Use the Compozy skills as an inspiration for quality bar: technical rigor, explicit gates, verification discipline, review structure, controlled scope, and operational clarity. Do not vendor or copy content from either repository unless explicitly requested.
Primary workflow:
IDEA → PLAN → PRD → SPEC → TASKS → EXEC → REVIEW
The public Pi skill commands are intentionally prefixed with sdd-:
/skill:sdd-init
/skill:sdd-steering
/skill:sdd-idea
/skill:sdd-plan
/skill:sdd-prd
/skill:sdd-spec
/skill:sdd-tasks
/skill:sdd-exec
/skill:sdd-review
/skill:sdd-status
Do not reintroduce /sdd:* extension aliases unless explicitly requested.
Language Policy
Repository source, README, skills, templates, and package documentation should be written in EN-US.
Runtime behavior documented by the skills is different:
- skills should respond in the user's initial chat language;
- skills should write generated project artifacts in the user's initial chat language;
- paths, file names, status values, commands, IDs, and code symbols remain canonical and should not be translated.

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.

pi-sdd-kit AGENTS.md is an instructions file published in the GitHub repository felipefontoura/pi-sdd-kit (36 stars, last pushed 6d ago), licensed MIT. It adds 2,122 tokens to every session, about $0.0085 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.
