Changelog

Engine v2. Seven verbs, file-backed memory, MCP-only composition. For the version-matched agent contract at any time: agent-webmcp skill show.

0.1.0

• Seven verbs: open list search register execute close unregister. Composition (search, execute) is MCP-only; the CLI mirrors lifecycle plus doctor, mcp list/serve, skill show.
• Sessions: owned headless Chromium by default, --headed opt-in, --cdp borrows a foreign tab (it gets navigated — stated cost). close kills only owned browsers (TERM→wait→KILL, profile removed every path); foreign pids are never signaled.
• Custom tools: spec plus plain-JS body, compiled debugger-side (CSP-exempt), fixture-proved before persisting (consequential tools hand-proved). Saved as <root>/<origin-slug>/<name>/{spec.json,body.js}; every open re-applies; rot surfaces as staleSuspect; recovery is re-register.
• Codemode: search ranks across sessions with deterministic field weights; execute runs one program over flat or namespaced (sessions[]) tools with enforced budgets. Every envelope carries untrusted: true.
• Honesty rules: piped output is JSON, writes need --yes, exits 0 ok / 2 usage / 1 failure with the message on stderr.
• Install: Bun toolchain, Chromium 152+, source build (bun run gate, bun run compile); per-OS release binaries attach from this version on.

How to read this log

Entries name the verb or door they change and the evidence to expect (reapplied[], skipped[], staleSuspect, envelope fields). Behaviour strings quoted here match CLI and MCP output verbatim — if output and log ever disagree, the output wins and the log gets a correction entry.
