v1.16.0

Added

• Five quality-of-life improvements:
  • Multilingual routing: the PreToolUse classifier now scores English AND Italian delegation
    intent (delegate, subagent(s), fan out, delega, subagente/i, in parallelo,
    rifattorizza…) up, and quick-look intent (cerca, veloce, esplora…) down.
  • Free-model auto-detection in sync: models:sync prints NEW free models detected: …;
    --auto-free promotes them straight to tier 0 (curated default never stolen).
  • Per-account budget caps: budget.accounts.<name>.maxDailyCostUsd is enforced at delegate
    time against that account's own daily spend (BUDGET_ACCOUNT_DAILY_MAX) on top of global
    caps; computeSpend buckets today's spend per account.
  • Race winner reasoning: fanOut mode:"race" now returns the winner's reasoningTail
    (last ~600 chars of chain-of-thought) for cross-model quality comparison.
  • Persistent activity buffer: the in-memory feed survives MCP server restarts via a
    throttled snapshot (state/activity-buffer.json, 300 lines × 100 jobs), reloaded lazily.
• Live activity visibility — zero files by default: every delegated session's
  chain-of-thought reasoning, assistant output, tool-call state transitions
  (bash (running) {command…}, deduped per status), permission asks and lifecycle notes are
  captured in an in-memory per-job buffer inside the MCP server.
  • wait progress frames now stream a rich one-line feed (reasoning · latest tool · assistant
    tail) into Claude Code's console under the running call — like watching a classic subagent.
  • New mcp__plugin_opencode_oc__logs {jobId?|sessionID?|lines?} tool tails that buffer
    (latest delegate job by default) plus live assistantTail/reasoningTail for running
    sessions; wired into the opencode-delegate agent and delegate/parallel commands.
    Tool count is now twelve.
  • Opt-in disk mirror (OPENCODE_ACTIVITY_LOG=1) enables the terminal follower
    node plugins/opencode/scripts/oc-logs.mjs -f and the new /opencode:logs command.
• Proactive routing skill (skills/opencode-routing/SKILL.md): trigger-rich description
  ("subagents, delegation, parallel workers, background tasks, fan-out") with an explicit
  anti-overuse guard — routine single-file edits, exploration and quick questions stay local.
  Delegation fires when the user asks for it, not on every task.

Changed

• Docs: model catalog truth + "Adding models" guide. README gains a step-by-step section for
  adding models (live-catalog prerequisite, model add flags, verify loop, error table,
  free-only reality). Agent/skill tier guidance no longer advertises deepseek/kimi fallbacks —
  tiers 1-3 are empty under the current excluded list and a failed free run must be reported
  BLOCKED, not escalated to an excluded model.
• Agent trigger phrases: opencode-delegate description now says "Use PROACTIVELY when the
  user asks for subagents, delegation, parallel workers, background tasks or fan-out work" plus
  explicit exclusions — this is the field Claude Code matches user wording against.
• Part tracker captures reasoning parts alongside text; permission watcher exposes
  reasoningText() and an optional onEvent sink hook.
• Catalog resync (2026-08-24): metadata refresh only — same 62 ids, contract/defaults/policies/
  excluded untouched. Live catalog currently offers NO free model beyond the seven already
  configured (big-pickle, hy3-free, mimo-v2.5-free, nemotron-3-ultra-free,
  nemotron-3.5-lightning-free, ox-alpha-free, x-preview-f-free); addModel→validate→resolve
  path re-verified for future additions (duplicate guard, tier-0 resolution).

Fixed

• Router hook tier inconsistency: delegation advice no longer hardcodes tier:1 (a paid
  tier under the current free-only policy) — it instructs delegate {task, autoRetry:true}
  without tier/model so the resolver applies defaults.tier: 0.
• Windows CI flake (windows-smoke): the smoke job could fail right after npm i -g
  with "opencode not found on PATH" — a runner PATH-refresh race. Fixes: npm global prefix is
  pinned to PATH via GITHUB_PATH, resolveOpencodeCommand() additionally probes the standard
  %APPDATA%\npm shim locations when where.exe misses, negative lookups are no longer cached
  (so retries heal), and the smoke script retries doctor's binary check 3× before failing.
