capture-ready SKILL.md skillA
capture-ready from cognitive-fab/polygraph is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add cognitive-fab/polygraph/capture-ready@git:20260807.2705388Pins git:20260807.2705388 in mdr.lock. Pin the fingerprint instead.

Author stateful code capture-ready BY CONSTRUCTION, in ANY language — so verification never needs an instrumentation retrofit. Apply whenever writing or substantially reshaping a state machine, workflow, reducer, store, or protocol handler in any session and any language (Python, Go, Rust, Java, TS outside polygen, …): shape the module to the eight CR requirements (one named step boundary, declared observable projection, observable rejections, a step-listener seam from the first commit…
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
# capture-ready — write it instrumented, so nobody retrofits traces
The Polygraph toolchain starts working at code-generation time, not at
verification time. Every other capture path in this repo answers "the code
exists; how do I get traces out of it?" — instrument a copy, keep a patch,
hope it doesn't rot. That retrofit is only ever necessary because the code
was **shaped** without capture in mind. This skill states the rule for code
an agent writes: get the shape right at authoring time and the corpus falls
out of a listener registration — no patch, no seam hunt, nothing to
re-derive when the code moves.
Source of truth (ships with the plugin — read it when detail is needed):
`${CLAUDE_PLUGIN_ROOT}/docs/capture-ready.md`. The retrofit path for code we
did NOT write is unchanged (`polygraph` skill Step 2 + `docs/capture-spec.md`)
— never reshape someone else's target to make it easier to capture.
> Scope disclosure: capture-ready is not verified and not evidence — a module
> can satisfy all eight requirements and be wrong. It is the precondition
> that makes verification cheap and repeatable.

How to install
mdr add cognitive-fab/polygraph/capture-ready@sha256:3c4561f1a9fed9adThe line at the top of this page pins the label git:20260807.2705388, 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.
