Documentation

README

Excerpt

Agent Session Format Check

Answer one precise question for every supported agent:

Can current Agent Sessions code support the latest available session/storage/usage format from the latest available agent build?

The answer must be layered. Do not collapse version checks, stale samples, schema fingerprints, discovery contracts, and usage probes into a vague severity label.

Evidence-first:

Gather a report + sample paths first.
Do not change parsers/fixtures/docs without explicit user approval.

Related skill: agent-support-matrix — maintains the matrix YAML, ledger, and update-checklist workflow. This skill focuses on detection and evidence collection; agent-support-matrix focuses on recording and gating version bumps.

This is the opening of the README. Read the full README on GitHub.
