cascade-dedup SKILL.md skillA
cascade-dedup from outlinedriven/outline-driven-development is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add outlinedriven/outline-driven-development/cascade-dedup@git:20260905.1f63894Pins git:20260905.1f63894 in mdr.lock. Pin the fingerprint instead.

Use when prompt-doctrine is duplicated, drifted, or conflicting across output-style embeds and external harness AGENTS files. Not for editing the canonical baseline itself.
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
# Cascade dedup
## Contract
| Field | Bound contract |
|---|---|
| Trigger | Prompt-doctrine duplication, drift, or conflict across the cascade family. |
| Authority | Human-gated: previews the target and consequence before rewriting prompt doctrine at rest, bumping the catalog `releaseVersion`, or editing authorized external harness embeds; every other write is reversible local, with version control as the rollback. |
| Side effect | Rewrites cascade prefixes/tails, bumps the catalog `releaseVersion` and re-renders package surfaces, and edits authorized external embeds. |
| Done | All canonical tails match, every strip is evidenced, divergence ledger complete, verification green. |
## Inputs
- The canonical baseline file `system-prompt-baseline.md`, must exist and be the agreed source of truth.
- The six output-style embeds: `plugins/odin-core/output-styles/{axiom-mode,builder,duet,linus,odin,benchmark}.md`.
- The two external harness embeds: `~/.omp/agent/AGENTS.md` and `~/.codex/AGENTS.md`.
- Explicit user authorization, recorded in the run, before any `benchmark.md` tail repair or authorized external embed edit.
## Procedure
…Read the whole file at its exact version.
How to install
mdr add outlinedriven/outline-driven-development/cascade-dedup@sha256:b6a6fcaa25590c90The line at the top of this page pins the label git:20260905.1f63894, 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.
