gate SKILL.md skillA
gate from skillberry-ai/cap-evolve is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add skillberry-ai/cap-evolve/gate@git:20260822.64b5e5bPins git:20260822.64b5e5b in mdr.lock. Pin the fingerprint instead.

Apply the acceptance decision that keeps optimization honest — always on the val split, by default requiring the improvement to exceed the significance bar (Δ > k·SE) so noise is not mistaken for progress. Use to inspect or reproduce a single accept/reject decision; the algorithms apply it internally every iteration.
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
# gate — accept only real improvements, on val
The gate is where dishonest optimization is prevented. Search is a noise
amplifier: try enough candidates and some will *look* better by chance alone
(the more candidates you screen, the larger the expected best-of-noise). The gate
is the rule that keeps a lucky draw from being promoted to "the new best". It
refuses any split but `val`, and by default accepts a candidate only when its val
reward beats the current best by **more than `k` standard errors**.
## Inputs / outputs (manifest tokens)
- **needs:** `scores` — the candidate's and current best's val reward *and*
`stderr` (from `evaluate`). The SE is not optional: significance is meaningless
without it.
- **provides:** `decision` — `{accept, reason, delta, threshold}`, the audit
record of why a candidate was kept or rejected.
## The significance rule
```
paired (the default): accept ⟺ mean(Δ[t]) > k · SE(Δ) over the SAME val tasks
significant (fallback): accept ⟺ Δ = cand − curr > k · sqrt(cand_se² + curr_se²)
```
The bar is `Δ > k·SE` and **not `Δ > 0`** because search is a noise amplifier:

How to install
mdr add skillberry-ai/cap-evolve/gate@sha256:e8a8d6f59f041cd1The line at the top of this page pins the label git:20260822.64b5e5b, 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.
