synthesis-skill-router SKILL.md skillA

synthesis-skill-router from synthesisengineering/synthesis-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add synthesisengineering/synthesis-skills/synthesis-skill-router@v2.0.1

Pins v2.0.1 in mdr.lock. Pin the fingerprint instead.

Route a request to the right synthesis engineering, coding, writing, project-management, knowledge, operations or agent-governance skill while keeping specialist metadata out of Codex's bounded prompt. Use when a task appears to match a synthesis workflow but the user did not name the exact skill.

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

# Synthesis Skill Router

Pick the synthesis skill that owns a request and load it. Most synthesis skills keep their metadata out of Codex's bounded prompt, so this routing table is how an agent finds them.

## Binding rules

1. Choose the narrowest matching workflow, then read its sibling `SKILL.md` completely before acting.
2. Resolve every path relative to this skill's directory.
3. Load multiple skills when the request crosses categories; their `depends_on` declarations remain authoritative.
4. Route by the requested outcome and the current stage.
5. Load operative references when their task shape applies, without copying entire catalogs into each run.
6. Preserve mandatory evidence, authority, coordination and domain checks.
7. Loading a skill does not reopen a settled decision or turn delegated implementation choices into user approval gates; use the [decision-ownership contract](../synthesis-thinking-framework/references/decision-ownership.md) when instructions appear to disagree.
8. Do not substitute this routing summary for the selected skill's instructions.

How to install

The exact contents, by fingerprint
mdr add synthesisengineering/synthesis-skills/synthesis-skill-router@sha256:6a8394f59de86d76

The line at the top of this page pins the label v2.0.1, 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.
