Agent Plugins client E2E evidence

For the current source-built Linux client matrix and its release boundary, see the public compatibility reference and compact evidence identities. The macOS record below remains historical evidence for UAP 0.1.22.

This record binds the public client-support claims to one exact, disposable macOS run. It is lifecycle and client-discovery evidence, not a browser tool, model, OAuth, or login runtime claim.

The run used fresh temporary HOME, XDG, Claude, Gemini, Cline, and agentplugins state directories. It did not read or mutate an agent project or the user's client configuration. A separate read-only doctor inventory confirmed that all five selected client families were present on the host.

Lifecycle proof

The same exact package acquisition was applied to all five clients:

agentplugins add ChromeDevTools/chrome-devtools-mcp@cb39d1d835c3baa3eff87501cd8c1de020604789 \
  --target claude,gemini,opencode,cline,windsurf \
  --format json

The operation produced one installation ID and reported all five targets as installed against the same tree and manifest digests. The following client checks were then run inside the disposable profile.

Client Exact check and result
Claude Code 2.1.205 claude plugin list --json returned the enabled chrome-devtools package, its six skills, and the chrome-devtools MCP server.
Gemini CLI 0.36.0 gemini mcp list returned the configured chrome-devtools stdio server; gemini skills list discovered all six skills. The MCP process was Disconnected, so browser/runtime execution is not claimed.
OpenCode 1.18.4 opencode debug config returned the exact managed MCP command, working directory, PLUGIN_ROOT, and PLUGIN_DATA. Runtime tool execution is not claimed.
Cline The isolated native MCP settings contained the exact managed server and all six skills were projected. The real host detector found the installed Cursor extension/config surfaces; Cline runtime and login were not started.
Windsurf / Devin The isolated legacy MCP settings contained the exact managed server. The real host detector found existing Devin/Windsurf configuration surfaces; skills remained prepared-only and runtime/login were not started.

doctor --format json completed read-only and found no projection drift. Its only findings were the expected authentication_not_checked notices because this run intentionally performed no login or OAuth flow.

An immutable full-SHA installation deliberately has no update channel. The multi-target update failed during preflight with no mutation and directed the user to switch --to with a new reviewed SHA. A repair then reacquired the exact recorded revision once and completed for every client:

agentplugins repair chrome-devtools \
  --target claude,gemini,opencode,cline,windsurf \
  --format json

The transcript records the exact update preflight and confirms the installation was unchanged. Directory-backed updates are a separate release/publication canary and are not inferred from this immutable-source run.

Finally, one multi-target remove succeeded for all five clients. Post-removal checks proved:

  • agentplugins list returned no installations;
  • Claude Code returned an empty plugin list;
  • Gemini CLI reported no MCP servers and no skills;
  • OpenCode returned an empty MCP map;
  • Cline and Windsurf MCP maps were empty;
  • the projected Gemini and Cline skill files were gone.

Plugin data was retained by default, matching the CLI's documented safe-remove contract. No browser, model, tool call, consent screen, or OAuth session was used in this evidence run.

Compatibility work dated 2026-09-06 is tracked separately in release preparation. This historical transcript does not prove the unreleased candidate's cwd or transport behavior.
