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 | $0.00006 | $0.00722 |
| Opus 5 | $0.00003 | $0.00361 |
| Sonnet 5 | $0.00001 | $0.00144 |
| Haiku 4.5 | $0.00001 | $0.00072 |
Grade A, and why
create-prototype 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 2d 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.

Create Prototype
Create fully functional client-side prototype for Feature Unit {{input:feature_id}}.
Follow foundation/development/feature_unit_workflow.md Step 1 (Prototype Creation). Configuration is read from foundation-config.yaml.
This happens after Checkpoint 0 (spec creation) and before Checkpoint 1 (prototype review).
Implements prototype creation after Checkpoint 0 (spec) is complete. Creates a fully interactive, client-side prototype with mocked APIs.
Trigger
- Spec created with UI requirements (Checkpoint 0 complete, UI changes present) OR
- No UI changes required (skip prototype)
Tasks
-
Load configuration:
- Read
foundation-config.yamlto get feature unit settings - Determine directory structure and prototype paths
- Read
-
Load spec and manifest:
{configured_directory}/in_progress/{{input:feature_id}}/{{input:feature_id}}_spec.md(orcompleted/if completed){configured_directory}/in_progress/{{input:feature_id}}/manifest.yaml(orcompleted/if completed)
-
Check if UI changes present:
- Review spec and manifest for UI components
- Verify UX Requirements section exists in spec (from Checkpoint 0)
- If no UI changes → skip to implementation
- If UI changes present → proceed
-
Create prototype:
- Use configured prototype directory structure (or default:
frontend/src/prototype/) - Create prototype component(s):
{prototype_dir}/components/{{input:feature_id}}_*.tsx - Create mock API fixtures:
{prototype_dir}/fixtures/{{input:feature_id}}_*.ts - Integrate into prototype main file
- Use configured prototype directory structure (or default:
-
Prototype requirements:
- Fully interactive (click, type, navigate)
- All API calls mocked (no real backend)
- All UI states testable (empty, error, loading, success)
- Accessible (keyboard nav, ARIA if applicable)
- Uses existing design system components (if available)
- Documented mock API responses
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.

create-prototype is a skill published in the GitHub repository markmhendrickson/neotoma (29 stars, last pushed 5d ago), licensed MIT. It adds 6 tokens to every session and 722 once invoked, about $0.0000 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.
