constraint-driven-development SKILL.md skillA

This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.

constraint-driven-development from outlinedriven/odin-claude-plugin is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add outlinedriven/odin-claude-plugin/constraint-driven-development@git:20260904.2014e73

Pins git:20260904.2014e73 in mdr.lock. Pin the fingerprint instead.

Use when asked to implement under non-negotiable constraints: performance budgets, platform limits, legal or API rules. Not for remote, credential, publish, deploy, or irreversible changes.

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-driven development

## Contract

| Field | Bound contract |
|---|---|
| Trigger | Implementing under explicit non-negotiable constraints such as performance budgets, platform limits, or legal or API rules. |
| Authority | Reversible local: writes only the constraints record and constrained code changes in the working tree; rollback is undo (revert those writes). No VCS history, credential, or remote mutation. |
| Side effect | A constraints record and the code changes that satisfy it, both local and revertible. |
| Done | All stated constraints verifiably pass in the delivered change and no unrelated behavior regressed, recorded in the constraints artifact. |

## Inputs

Required: the set of non-negotiable constraints the change must satisfy, each stated as a measurable predicate (a budget number, a platform limit, or a legal or API rule with a checkable condition). Optional: an existing constraints record that already governs the target tree. A constraint that arrives as prose without a measurable form must be converted to one before any code is written; a constraint that cannot be checked is unmeasurable and stops the run.

How to install

The exact contents, by fingerprint
mdr add outlinedriven/odin-claude-plugin/constraint-driven-development@sha256:f48ef5ad71ff2e99

The line at the top of this page pins the label git:20260904.2014e73, 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.
