testing-complexity-claims SKILL.md skillA

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

Install it, pinned
mdr add heikkitoivonen/python-time-space-complexity/testing-complexity-claims@git:20261016.472e85f

Pins git:20261016.472e85f in mdr.lock. Pin the fingerprint instead.

Designs and reviews tests for every complexity, behavioral, and performance claim in documentation. Use when adding or changing claims, auditing claim or API coverage, or creating module complexity tests.

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

# Testing Complexity Claims

Turn each documentation claim into executable evidence when execution can
settle it, and explicitly account for the claims it cannot settle.

## Model the File on the csv Tests

`tests/test_csv_complexity.py`, paired with `docs/stdlib/csv.md`, is the
reference test file. Read it in full before writing or reviewing a module's
tests, and shape the new file after it rather than after whichever test files
were touched most recently: a file modelled on its neighbours inherits their
departures from the reference and adds its own. The parts to reproduce:

- **A module docstring that carries the evidence.** It opens "Tests for
  docs/stdlib/<module>.md." and says in a paragraph how the page's claims are
  settled. A "Measurement scope:" list then gives the evidence per claim:
  for a timing or allocation measurement, the sizes used, the ratio or traced
  peak asserted, and where it matters the versions; for a direct behavioural
  check, what was observed; for a source-only bound, the released CPython
  file it follows from. A "Not settled here:" list closes it with the
  category C and D claims and the reason for each, and the dimensions the
…

How to install

The exact contents, by fingerprint
mdr add heikkitoivonen/python-time-space-complexity/testing-complexity-claims@sha256:f2452157beba24c0

The line at the top of this page pins the label git:20261016.472e85f, 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.
