What it does
Agent Support Matrix is an agent skill from jazzyalex/agent-sessions. Maintain Agent Sessions agent support matrix and JSON/JSONL parsing compatibility. Use when checking upstream agent releases for session format changes, updating max verified versions in docs/agent-support/agent-support-matrix.yml, or updating docs/agent-json-tracking.md and fixtures/tests.
Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/impact-scan.md`, `references/matrix-schema.md` and `references/update-checklist.md`).
It sits in Sales & Support, covering Customer support. The repository describes itself as: Local-first macOS app to browse, search, analyze, and resume supported AI coding-agent session history across Codex, Claude Code, OpenCode, Cursor Agent, Antigravity, Hermes… The licence is MIT.
When your agent uses it
- Checking upstream agent releases for session format changes
- Updating max verified versions in docs/agent-support/agent-support-matrix.yml
- Updating docs/agent-json-tracking.md and fixtures/tests
Example prompts
- “/agent-support-matrix”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Read docs/agent-support/workflow.md.
- Run the session-format check and read results..compatibility.
- Compare latest available agent versions to docs/agent-support/agent-support-matrix.yml.
- If gaps exist, run an impact scan, collect evidence, and update fixtures/tests before
What it can do on your machine
Read from SKILL.md and the folder at commit 7711291. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Agent Support Matrix loads about 587 tokens when it runs, and up to ~1.3k if it reads all its reference files. Until then it costs about 78 tokens; SKILL.md has 219 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Agent Support Matrix
Overview
Keep the support matrix and memory bank accurate, and gate updates with evidence so parsing regressions are avoided.
Quick Start
- Read
docs/agent-support/workflow.md. - Run the session-format check and read
results.<agent>.compatibility. - Compare latest available agent versions to
docs/agent-support/agent-support-matrix.yml. - 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.pbxprojMARKETING_VERSION. - Run
./scripts/agent_watch.py --mode weeklyand usecompatibility.verdictas the support answer.severityandrecommendationare legacy escalation fields, not support claims. - Use
references/impact-scan.mdto inspect upstream releases for format changes. - Follow
references/update-checklist.mdbefore updating docs or fixtures.
Guardrails
- Do not bump
max_verified_versionwithout fixtures or sample logs plus passing parser tests. - Do not bump
max_verified_versionunlessresults.<agent>.compatibility.verdictissupports_latest, or the update explicitly records a narrower scope such assupports_installed_onlywith a blocker and follow-up. - If an agent does not log a version, keep
max_verified_version: "unknown"and document verification scope indocs/agent-json-tracking.md.
