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 | $0.00063 | $0.00967 |
| Opus 5 | $0.00032 | $0.00483 |
| Sonnet 5 | $0.00013 | $0.00193 |
| Haiku 4.5 | $0.00006 | $0.00097 |
Grade A, and why
sdd-steering 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.
How it starts
The opening of the file, as written. The whole thing — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AI Steering
Create or update reusable project context in .ai/steering/.
Purpose
Steering documents capture stable project guidance that many skills can reuse. They are not SDD feature artifacts; they describe the broader product, stack, principles, conventions, and domain rules that should guide IDEA, PLAN, PRD, SPEC, TASKS, EXEC, REVIEW, and other AI workflows. Because steering is durable project-wide context, draft freely but confirm before saving or changing global guidance.
Workflow
-
Load references.
- Read
../_shared/references/sdd-practical.md. - Apply the Language Policy: respond and write artifacts in the user's initial chat language while keeping skill instructions and templates in EN-US.
- Read
../_shared/references/templates.mdwhen drafting artifacts. - Use package-level
templates/steering-*.mdfiles as user-facing examples when available.
- Read
-
Establish the steering workspace.
- Use
.ai/steering/. - Create
.ai/steering/if it does not exist. - Read existing
.ai/steering/*.mdbefore changing them. - Briefly inspect project README, package files, docs, and source tree when useful.
- Use
-
Determine which steering docs are needed.
product.mdfor product vision, users, value, boundaries, success metrics, glossary.tech-stack.mdfor runtime, frameworks, libraries, infrastructure, verification commands, constraints.conventions.mdfor code style, architecture patterns, naming, testing, accessibility/security, workflow.principles.mdfor project principles, MUST/SHOULD rules, decision rules, review expectations, and governance-like guidance.- Domain-specific docs such as
lp.md,payments.md,brand.md, orcontent.mdwhen the user wants reusable guidance for a specific workflow.
-
Clarify missing context.
- Ask one question at a time.
- Prefer multiple-choice questions when useful.
- Do not over-interrogate; use existing project evidence when reliable.
- Mark uncertain items as Open Questions rather than inventing durable rules.
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.

sdd-steering is a skill published in the GitHub repository felipefontoura/pi-sdd-kit (23 stars, last pushed 2mo ago), licensed MIT. It adds 63 tokens to every session and 967 once invoked, about $0.0003 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.
