assurance-cli

PyPI Tests Python License

Did the job cover everything it was supposed to cover? Arithmetic, not models.

Install

pip install assurance-cli
# or: pip install assurance   # every tool

Quick start

assurance --help lists: init, check, diff, pin, drift, deps, budget, authority, audit. audit, budget, authority, and deps forward to their packages when installed.

Point check at a folder of dated files (real output from a temp folder with Jan, Feb, Apr CSVs):

$ assurance check reports
3 of 4 months from 2026-01 to 2026-04 in reports — not in this folder: March 2026 — Range inferred from filenames: earliest 2026-01, latest 2026-04 — uneven spacing, so monthly was read from the names rather than detected. Override with --expect / --from / --to.

With --fail-on-gap that same line exits 1.

diff compares any two sets of keys (no folder required). pin snapshots MCP tool definitions and detects drift. drift watches a binary outcome stream.

What it checks

  • Dated or numbered series in a folder (check) — months, weeks, days, numbered runs
  • Coverage over any two key sets (diff)
  • MCP tool-description drift since a pin (pin)
  • Shift in a binary outcome stream (drift)
  • Forwards: session audit, run budget, authority review, dependency install hooks

In CI

exit means
0 checked; no gap (or not asked to fail on one)
1 gap / unexpected key / stale pin / nothing it could check
2 could not run (bad path, missing sibling package, bad JSON)

Limits

  • Does not invent the expected set. diff takes your declaration; check derives one and prints how.
  • No network, no telemetry, no keys.
  • A folder it cannot parse exits 1, not 0 — silence is not a pass.
  • Skipped tool directories (.git, node_modules, …) are named, not folded into “files not opened” as if they were content.

See the root README and CHANGELOG.md.
