# Agent Support Matrix

## Overview

Keep the support matrix and memory bank accurate, and gate updates with evidence so parsing
regressions are avoided.

## Quick Start

1. Read `docs/agent-support/workflow.md`.
2. Run the session-format check and read `results.<agent>.compatibility`.
3. Compare latest available agent versions to `docs/agent-support/agent-support-matrix.yml`.
4. If gaps exist, run an impact scan, collect evidence, and update fixtures/tests before
   bumping `max_verified_version`.

## Workflow

- Determine the current Agent Sessions version from `AgentSessions.xcodeproj/project.pbxproj`
  `MARKETING_VERSION`.
- Run `./scripts/agent_watch.py --mode weekly` and use `compatibility.verdict` as the
  support answer. `severity` and `recommendation` are legacy escalation fields, not
  support claims.
- Use `references/impact-scan.md` to inspect upstream releases for format changes.
- Follow `references/update-checklist.md` before updating docs or fixtures.

## Guardrails

- Do not bump `max_verified_version` without fixtures or sample logs plus passing parser tests.
- Do not bump `max_verified_version` unless `results.<agent>.compatibility.verdict` is
  `supports_latest`, or the update explicitly records a narrower scope such as
  `supports_installed_only` with a blocker and follow-up.
- If an agent does not log a version, keep `max_verified_version: "unknown"` and document
  verification scope in `docs/agent-json-tracking.md`.
