Accept apply_patch edits from nested result/metadata file lists and from raw patchText args when OpenCode does not provide direct metadata.files.
Forward tool args through the after-hook pipeline so comment-checker can inspect raw apply_patch inputs while preserving existing write, edit, and multiedit routing.

OpenCode now treats session.status idle as the durable completion boundary, but the plugin only dispatched the synthetic session.idle through the main hook chain. Idle-only side effects such as tmux forwarding and team member idle continuations were skipped.
Route synthetic idle through the same idle-only hook path used by real session.idle events and pin the behavior with a regression test.

Include Vertex Anthropic in the assistant-tail prefill guard after Cubic flagged the strict provider check. Keep the non-Anthropic opencode negative control covered by tests.
Plan: plans/fix-anthropic-assistant-prefill-tail.md
Tighten the assistant-tail repair after review so only the Anthropic provider is treated as prefill-rejecting, and so assistant-tail model metadata is evaluated independently from the last user model.
Add regression coverage for an allowed user model followed by a rejecting Anthropic assistant tail, plus a non-Anthropic provider carrying a Claude-looking model id.
Plan: plans/fix-anthropic-assistant-prefill-tail.md
Claude Opus 4.7 rejects requests whose final message is an assistant turn, because Anthropic treats that as unsupported assistant prefill. Add a transform guard that appends the existing synthetic user recovery turn only for Anthropic prefill-rejecting model IDs, while preserving assistant-prefill behavior for supported and unknown models.
Tests cover Opus 4.7, Opus 4.6 assistant metadata fallback, direct Sonnet 4.6 model fields, allowed OpenAI/Sonnet 4.5 tails, missing metadata, and compaction continuation compatibility.

The bundled createTodoDescriptionOverrideHook returns { 'tool.definition': fn }, but plugin-interface.ts never exposes 'tool.definition' as an OpenCode hook handler. Result: the hook is constructed by createToolGuardHooks (line 132-134 of src/plugin/hooks/create-tool-guard-hooks.ts) but the function is never invoked, so todowrite keeps using OpenCode's core 7 KB description instead of the 1.4 KB TODOWRITE_DESCRIPTION. User-defined plugins under ~/.config/opencode/plugin/*.js use the same hook contract and work fine, confirming the contract itself is functional in opencode 1.14.28+.
Fix: add src/plugin/tool-definition.ts (createToolDefinitionHandler) that forwards the OpenCode 'tool.definition' input/output pair into hooks.todoDescriptionOverride. Wire it into plugin-interface.ts alongside tool.execute.before/after.
Regression coverage: src/plugin/tool-definition.test.ts covers (a) todowrite override applied, (b) other tools left untouched, (c) null hook is a no-op.
Address Oracle review feedback: refactor 4 aliased mutations via argsObject
in plugin/tool-execute-before.ts and 1 via toolOutput in atlas/tool-execute-before.ts.
Strengthen audit test regex to catch Output.args mutations regardless of the
variable name prefix (toolOutput, argsObject aliases).

The team-mode wiring at `createEventHandler` extracted
`pluginContext.client.session.promptAsync` and `.status` into a fresh
wrapper object. The methods were copied by reference, so the prompt-async
gate's `session.promptAsync.bind(session)` was binding to that plain
wrapper rather than the underlying SDK `Session` instance. The opencode
SDK's `promptAsync` reads `this._client.post(...)`, so production calls
threw `TypeError: undefined is not an object (evaluating 'this._client')`
on the very first dispatch — fingerprinted in /tmp/oh-my-opencode.log as
688 `background-agent-parent-wake`, 47 `model-suggestion-retry`, and 4
`team-idle-wake-hint` failures over the past three days.
Move the wrapper construction into `buildTeamIdleWakeHintClient`, which
preserves the narrow factory contract while binding both methods back to
the SDK `Session` so `_client` survives the dispatch. Cover the contract
with four BDD-style tests including the historical destructure-only
failure mode so any future regression is caught at unit-test time.
Adds a new `notepad-write-guard` hook that intercepts Write tool calls
whose target path matches `**/.sisyphus/notepads/**` and throws an
actionable error instead of allowing the write to proceed.
Without this guard, an agent that hits an Edit hash-mismatch failure
could silently fall back to Write, destroying the entire history of an
append-only notepad file (decisions.md, issues.md, etc.). The file
carries an explicit "NEVER overwrite" warning that the agent ignores
under context pressure.
The guard is path-based so it works regardless of plan name or nesting
depth. Non-notepad `.sisyphus/**` paths (e.g. plan files) are
unaffected. The hook is wired into `create-tool-guard-hooks` under the
hook name `notepad-write-guard` and follows the same safeCreateHook +
HookName schema pattern as every other tool-guard hook.
