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 | $0.00060 | $0.00782 |
| Opus 5 | $0.00030 | $0.00391 |
| Sonnet 5 | $0.00012 | $0.00156 |
| Haiku 4.5 | $0.00006 | $0.00078 |
Grade A, and why
sdd-idea 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 9d 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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SDD Idea
Explore an idea before turning it into a plan, requirements, or code.
Purpose
Use this skill to create cognitive clarity before formal planning. IDEA is divergent: it explores the problem space, users, alternatives, value signals, constraints, risks, and possible directions. It does not commit the user to a roadmap or implementation.
Workflow
-
Load the SDD reference.
- 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.mdonly when writing the final artifact. - Use package-level
templates/idea.mdas the user-facing template when available. - Load relevant
.ai/steering/*.mdfiles when present, especially product, principles, or domain context. - If
.ai/strategy/handoff/strategy-brief.mdexists, read it as optional upstream context; use it to seed exploration, but do not require it or treat it as approved SDD scope.
- Read
-
Establish the workspace.
- Use
.ai/sdd/ideas/for idea artifacts. - Create
.ai/sdd/ideas/if it does not exist. - If
.ai/sdd/PLAN.mdor.ai/sdd/specs/exists, briefly inspect them to avoid duplicating an existing direction. - If using the optional strategy handoff, record it as a source path in the idea artifact.
- Use
-
Explore the raw idea.
- Ask one question at a time.
- Prefer multiple-choice questions when useful.
- Cover at least: problem, target users, current alternatives, desired outcome, constraints, success signals, and risk.
- Do not ask implementation-first questions unless the idea is explicitly technical.
-
Present directions.
- Propose 2-3 possible directions.
- Include trade-offs: speed, complexity, user value, and risk.
- Recommend one direction, but preserve dissenting alternatives.
- Ask the user whether to continue exploring, create a PLAN, create REQUIREMENTS directly, or archive the idea.
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-idea is a skill published in the GitHub repository felipefontoura/pi-sdd-kit (22 stars, last pushed 2mo ago), licensed MIT. It adds 60 tokens to every session and 782 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.
