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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00313 | $0.00313 |
| Opus 5 | $0.00156 | $0.00156 |
| Sonnet 5 | $0.00063 | $0.00063 |
| Haiku 4.5 | $0.00031 | $0.00031 |
Grade A, and why
minimal-hard-rules 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
Hard Rules (Minimal Template)
Customize this file for your tech stack. These rules are always applied.
Mode Trigger Enforcement
When ANY mode trigger keyword is detected, you MUST:
- STOP - Do NOT take any action yet
- READ the full mode file
- EXECUTE phases in order
- WAIT at each gate for user confirmation
| Keywords | Mode File |
|---|---|
| "init", "start feature" | modes/init.mdc |
| "ask", "explore" | modes/ask.mdc |
| "plan", "design" | modes/plan.mdc |
| "commit" | modes/commit.mdc |
| "push PR" | modes/push-pr.mdc |
Code Quality
# Update these commands for your project
npm run typecheck # Type checking
npm run lint # Linting
npm run test # Testing
Reuse First
Before creating ANYTHING new, search for existing:
- Components in your UI library
- Hooks for common logic
- Services for API calls
- Types and interfaces
Communication
- First sentence = answer or decision (BLUF)
- Use tables for structured data
- No filler phrases ("I will now...", "Sure!")
Deployment
- NEVER push directly to main branch
- ALL changes through PR process
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.

minimal-hard-rules is a cursor rule published in the GitHub repository WellApp-ai/Well (339 stars, last pushed 28d ago), licensed MIT. It adds 313 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.
