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 | $0.00315 | $0.00315 |
| Opus 5 | $0.00158 | $0.00158 |
| Sonnet 5 | $0.00063 | $0.00063 |
| Haiku 4.5 | $0.00032 | $0.00032 |
Grade A, and why
designpowers CLAUDE.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 5d 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
Designpowers
This is the Designpowers design workflow system.
Mandatory: Welcome Sequence First
Before doing anything else in a new session, you MUST run the welcome sequence defined in skills/using-designpowers/SKILL.md. This is non-negotiable.
- Invoke the
using-designpowersskill using the Skill tool before responding to any user message - The skill will show the bird welcome screen and handle onboarding
- Do NOT skip the welcome, do NOT jump straight into design work, do NOT answer questions before the welcome runs
The welcome sequence checks for a returning user (taste profile at ~/.designpowers/taste-profile.md) and shows the appropriate welcome screen with the bird. First-time users get offered a guided walkthrough. This must happen before any design work begins.
Specifically: do NOT invoke design-discovery, design-strategy, design-memory, design-state, design-taste, or any other Designpowers skill until the welcome sequence has completed. The bird must appear. The user must see the greeting and the walkthrough offer. Only then can the pipeline begin. If any skill is invoked before the welcome, stop and run the welcome first.
Skills
All design skills live in skills/. The entry point is skills/using-designpowers/SKILL.md which orchestrates the entire workflow. Never bypass it.
Agents
Design agents live in agents/. They are invoked by the workflow — do not call them directly without going through the skill orchestration.
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.

designpowers CLAUDE.md is an instructions file published in the GitHub repository Owl-Listener/designpowers (240 stars, last pushed 2mo ago), licensed MIT. It adds 315 tokens to every session, about $0.0016 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.
