theory-fidelity SKILL.md skillA
theory-fidelity from haabe/mycelium is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add haabe/mycelium/theory-fidelity@git:20261023.872e334Pins git:20261023.872e334 in mdr.lock. Pin the fingerprint instead.

Audit whether the theories/methodologies a project claims to implement are faithfully operationalized — or name-dropped, partially built, distorted, or over-claimed. Source-grounds the load-bearing theories; tags the rest provisional. Run periodically alongside /framework-health.
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
# Theory Fidelity Audit Most framework checks evaluate *process* (cycle health, gates) or *artifact performance* (evals, DORA). None of them ask the question this skill exists for: **for every theory a project claims to represent, is the mapped mechanism actually faithful to what the theory says — or is it theatre?** This is the audit of the theory→mechanism mapping itself. The framework's own stated bar (`docs/theories.md`): *"every theory is mechanism-mapped … citations without mechanism-mapping are theatre."* This skill holds the project to that bar — including holding the theory doc to it. ## When to Use - Quarterly, alongside `/mycelium:framework-health` (process health) — this is the theory-fidelity half. - After adding/citing a new theory, or after editing a theory's mechanism (skill/gate/schema). - When a citation looks decorative, or when a doc claims a mechanism you suspect doesn't exist. ## The Grading Rubric (five axes) For each claimed theory, record: 1. **Representation** — `Mechanized` (a skill/gate/schema/canvas applies it) · `Prose-only` (cited + described, no mechanism) · `Absent`. 2. **Fidelity** (only if Mechanized): …

How to install
mdr add haabe/mycelium/theory-fidelity@sha256:5b3fa9295c4ca95cThe line at the top of this page pins the label git:20261023.872e334, 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.
