constraint-design SKILL.md skillA
constraint-design from habitat-thinking/ai-literacy-superpowers is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add habitat-thinking/ai-literacy-superpowers/constraint-design@git:20260414.c0e094aPins git:20260414.c0e094a in mdr.lock. Pin the fingerprint instead.

This skill should be used when the user asks to "add a constraint", "design a constraint", "write a harness rule", "choose enforcement type", "promote a constraint", "configure a verification slot", or needs guidance on the Constraints section of HARNESS.md.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Constraint Design A constraint is a rule that must be enforced — not a suggestion, but a hard boundary. In the harness framework, each constraint occupies a **verification slot** that can be filled by either a deterministic tool or an agent-based review. The system does not care which backs the slot; only whether the constraint passed. ## Anatomy of a Constraint Every constraint in HARNESS.md has four fields: - **Rule** — what must be true, written precisely enough for objective verification - **Enforcement** — `deterministic`, `agent`, or `unverified` - **Tool** — which tool or agent checks this (or "none yet") - **Scope** — when the check runs: `commit`, `pr`, `weekly`, `manual` ## Writing a Verifiable Rule The rule field is the most important. Apply the same enforceability test used for conventions: 1. Describe what compliant code looks like 2. Describe what violating code looks like 3. Confirm a reviewer (human or agent) could check this without ambiguity Consult the `context-engineering` skill's convention patterns for detailed examples. ## Choosing Enforcement Type | Question | If yes | If no | | --- | --- | --- | …

How to install
mdr add habitat-thinking/ai-literacy-superpowers/constraint-design@sha256:ccb685e3253f25ebThe line at the top of this page pins the label git:20260414.c0e094a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
