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.

What it costs to keep this loaded
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 | $0.00088 | $0.01121 |
| Opus 5 | $0.00044 | $0.00561 |
| Sonnet 5 | $0.00018 | $0.00224 |
| Haiku 4.5 | $0.00009 | $0.00112 |
Grade A, and why
product-design-user-context 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 — 148 lines — stays where its author put it; the contents beside it link to each section on GitHub.
User Context
User Context stores the product and design references a designer uses often, so future Product Design work starts from the right sources.
Use this skill when the user asks to:
- set up Product Design
- get started with Product Design
- onboard with Product Design
- save product or design sources
- see what Product Design remembers
- update saved product or design context
- remember a Product Design preference
- setup my plugin
Critical Overrides
- Refer to the Plugin router $index before proceeding.
- Follow $critical-overrides.
Saved User Context
If user-context.md exists, use it by default.
Use saved product URLs, Figma files, screenshots, reference images, codebase paths, Storybook, tokens, design systems, brand assets, component refs, browser preferences, and share targets to ground Product Design work.
Ideation, prototypes, audits, clones, and critiques should match the saved product context unless the user asks for something different.
When a workflow needs visual grounding, attach or include relevant saved screenshots, reference images, tokens, design language, and component references in ImageGen, ideation, prototype, audit, and critique work.
State File
Saved context lives here:
~/.open-cowork/state/plugins/product-design/user-context.md
Saved screenshots and reference images live next to it:
~/.open-cowork/state/plugins/product-design/assets/
If the file does not exist, continue normally unless the user asks to set up Product Design, save context, or the current task is blocked by missing product/design context.
Preflight
When any Product Design workflow needs saved context, run:
python3 scripts/user_context_preflight.py
Use the returned saved entries as the starting context for the task.
If the script reports that no saved context exists, continue from the current user prompt unless setup context is required.
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

product-design-user-context is a skill published in the GitHub repository AIDotNet/OpenCowork (635 stars, last pushed 7d ago), licensed Apache-2.0. It adds 88 tokens to every session and 1,121 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.
