Use when a measured cost surface needs one-change-at-a-time reduction under frozen guardrails. Not for speed-only optimization: use optimize.

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

# Cost reduction

## Contract

| Field | Bound contract |
|---|---|
| Trigger | A measured cost surface needs one-change-at-a-time reduction under frozen guardrails. |
| Authority | Human-gated: asks the human once before any production billing/infra mutation; otherwise reversible local: runs the pre-registered gate batteries and writes only to an append-only experiment log; rollback is version control. No remote mutation. Prose consent, invocation consent, prior-run consent, and post-start discovery do not approve an effect; end the run on scope drift. |
| Side effect | Guardrail-safe measured cost reduction. Each proposed change is adopted with N=5 gate evidence or recorded dead with the measurement that killed it. |
| Done | The fixed budget target is reached without any guardrail regression, or every proposed change is resolved as adopted or dead. |
| Stop | no safe saving; no progress; blocked. Bound: exact approved billing/infra scope, budget target, guardrails, and pass cap. |

## Inputs

- Approved scope (required): the billing or infrastructure surface to reduce, frozen before mutation.
- Budget target (required): the cost reduction goal.

How to install

The exact contents, by fingerprint

mdr add outlinedriven/outline-driven-development/cost-reduction@sha256:f550642326e684ba

The line at the top of this page pins the label git:20260912.5c5b759, 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.
