evaluating-skill-recall SKILL.md skillA
evaluating-skill-recall from heikkitoivonen/python-time-space-complexity is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Writes, runs and adjudicates the python-complexity skill's recall evaluation (skills/evals/, scripts/skill_eval.py). Use when adding or changing evaluation items, rerunning after a skill release or for another model, or deciding whether a model or the answer key is right where they disagree.
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
# Evaluating Skill Recall `make skills-recall` asks 100 single-operation questions with and without the skill and scores the stated bounds. [skills/evaluations.md](../../../skills/evaluations.md) describes the method and the result files; read it first. This skill covers the judgement the scripts cannot make: what makes an item answerable, and who is wrong when a model and a key disagree. ## Write an Item An item is only as good as its wording. A key that is right for the page's row can still be wrong for the question as asked, and a capable model will answer the question as asked. - **Name every size variable the bound may use.** `lst[i:j]` needs i and j listed as variables (`i = the slice start; j = the slice stop`), or models bound it by n. Leave out variables the key does not use: `dq[i]` asked at the costliest index has only n. - **State the condition that makes the key tight.** `s.rfind(sub)` reaches Θ(n·m) only while Θ(n) start positions remain, which fails at m = n, so the item requires `len(sub) <= len(s) / 2`; `heapq.merge` needs r >= 2 inputs for O(r + m log r); `x in range(n)` takes its O(1) arithmetic path only for an …

How to install
mdr add heikkitoivonen/python-time-space-complexity/evaluating-skill-recall@sha256:7184a0511eec6e74The line at the top of this page pins the label git:20261018.9800f92, 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.
