 The plugin injects adaptive-thinking guidance into the system prompt and exposes a tool for switching to one of the current model's valid reasoning-effort variants.
 
+## Requirements
+
+- OpenCode with plugin support compatible with `@opencode-ai/plugin` `^1.14.24`.
+- A selected model that exposes reasoning-effort variants such as `none`, `low`, `medium`, `high`, or `xhigh`.
+
+## Installation
+
+Add the package to your OpenCode config plugin list:
+
+```json
+{
+  "$schema": "https://opencode.ai/config.json",
+  "plugin": ["opencode-adaptive-thinking"]
+}
+```
+
+To customize behavior, use the tuple form shown in the configuration example below.
+
 ## Configuration

 }
 ```
 
+## Behavior
+
+Agents receive system guidance to actively choose the lowest reasoning effort that can safely complete the task. The plugin also exposes the configured tool, `set_reasoning_effort` by default, with these arguments:
+
+- `level`: one of the valid reasoning-effort variants for the current model.
+- `persist`: when `true`, keep the selected effort for the session. When `false` or omitted, apply it temporarily and reset to the previous effort after `session.idle`.
+
+Example temporary change:
+
+```json
+{
+  "level": "high",
+  "persist": false
+}
+```
+
+Example persisted change:
+
+```json
+{
+  "level": "low",
+  "persist": true
+}
+```
+
+The system prompt lists the valid levels for the current session. Cached session state is only used when it is still valid for the current model, so switching models will not advertise or reuse an invalid effort level.
+
+## Troubleshooting
+
+If the tool returns `no valid reasoning effort levels are available for this session`, check that the active model exposes variants in OpenCode. Some providers or models may not support reasoning-effort levels.
+
+If the tool returns `Invalid reasoning effort level`, use one of the levels listed in the system prompt for the current session.
+
+If configuration errors appear, check the plugin options against the documented keys and value types. Set `quiet` to `true` to suppress configuration error toasts while still writing details to the OpenCode logs.

 ## Narrative
 ### Structure
-The implementation centralizes plugin configuration in src/config.ts and threads the validated options into AdaptiveThinkingPlugin so runtime behavior and exposed tool metadata can be customized.
+Configuration is defined in src/config.ts, consumed by src/index.ts, and documented in README.md. Tests cover disabled plugin behavior, invalid config handling, custom tool metadata, custom system prompt, and default-options regression.
 
 ### Dependencies
-Depends on the existing opencode-byterover config pattern, Zod validation, and the plugin runtime that shows toasts and logs errors on invalid configuration.
+Uses Zod for schema validation and relies on high-signal tests to protect the public config surface.
 
 ### Highlights
-Tests, typecheck, lint, format check, and build all passed after the implementation. Validation only found formatting drift in src/index.test.ts before formatting was applied.
+The config surface is intentionally kept small and does not expose serviceName. Default behavior is treated as a regression requirement.

+
+## Narrative
+### Structure
+The plugin previously kept state in three module-level Maps; it now uses a single bounded LRU cache to prevent growth in long-running processes.
+
+### Dependencies
+Requires regression tests to preserve default behavior and eviction semantics while keeping the implementation type-safe.
+
+### Highlights
+The cache is capped at 500 sessions and protects the process from unbounded memory growth.

 ## Narrative
 ### Structure
-This entry records a live-session reasoning-effort state change and the expected follow-up idle reset behavior.
+The update spans production logic in src/index.ts, coverage in src/index.test.ts, and user-facing documentation in README.md.
 
 ### Dependencies
-The behavior depends on the session state machine and validation for allowed reasoning effort levels.
+The behavior depends on current model validity, cached reasoning state, and agent resolution order.
 
 ### Highlights
-A temporary low setting was accepted, an invalid level was rejected, and the next idle transition should restore medium only once.
+The work completed successfully after tests turned green, and the verification suite passed in full.
 
 ### Rules
 Temporary reasoning effort now resets only once on session.idle. Reset prompts are ignored and should not remain visible in-context. Invalid levels are rejected before calling promptAsync or mutating state.
 
 ### Examples
-Checks that passed included pnpm run test, pnpm run typecheck, pnpm run lint, pnpm run format:check, and pnpm run build.
+Examples mentioned include quiet invalid-config handling, stale cache invalidation, and newest-agent fallback resolution.
 
 ## Facts
-- **reasoning_effort**: Reasoning effort was set to low in a live session. [project]
-- **reasoning_effort_validation**: Invalid reasoning effort levels are rejected before mutation. [project]
-- **reasoning_effort_reset_behavior**: The temporary low reasoning effort should reset to medium once on idle, then stop repeating. [project]
-- **verification_status**: Automated checks passed: test, typecheck, lint, format:check, and build. [project]
+- **reasoning_effort**: Reasoning effort was set to high [project]
+- **quiet_invalid_config_behavior**: The implementation now honors quiet: true for invalid config to suppress toast while still logging [project]
+- **stale_cached_variants**: Cached reasoning effort is ignored when it is invalid for the current model [project]
+- **agent_fallback_resolution**: Fallback agent resolution uses the newest relevant agent [project]
+- **test_coverage**: Regression tests were added for quiet config errors, stale cached variants, newest-agent fallback, provider lookup failure, and reset failure recovery [project]
+- **verification_suite**: The project verification suite passed: format:check, lint, typecheck, test, and build [project]
+- **test_results**: The test suite reported 15 passed [project]

+title: Contract Parity Matrix Review
+updatedAt: '2026-04-25T18:42:43.537Z'
+---
+## Reason
+Capture durable review findings about test matrix coverage and streaming grammar parity
+
+## Raw Concept
+**Task:**
+Document the review outcome for the contract parity matrix and upstream streaming parity work
+
+**Changes:**
+- Reviewed contract parity matrix test coverage
+- Identified incomplete Anthropic native streaming grammar decoding
+- Identified incomplete Google native streaming event decoding
+
+**Flow:**
+run matrix tests -> inspect coverage -> compare against approved plan -> record compliance verdict and residual risks
+
+**Timestamp:** 2026-04-25
+
+**Author:** assistant
+
+## Narrative
+### Structure
+The review centered on the contract_parity_matrix test file and upstream streaming decoders, with the approved implementation plan used as the compliance target.
+
+### Dependencies
+Compliance depended on full 3x3 matrix coverage, richer canonical streaming event decoding for Anthropic and Google, and avoiding bogus empty Google terminal chunks.
+
+### Highlights
+The test command passed with 6 tests, but the suite did not prove the full matrix closure required by the plan. Native streaming parity for Anthropic and Google remained incomplete.
+
+### Rules
+Verdict: NOT_COMPLIANT
+
+### Examples
+Residual risk noted: cargo test -p commissary-api --test contract_parity_matrix passed, but the suite was too narrow to prove plan compliance.

+- **matrix_coverage**: The contract parity matrix suite was too small to prove the plan-required full 3x3 closure [project]
+- **anthropic_stream_grammar**: Anthropic native stream decoding did not preserve the full block grammar [project]

+summary: Opened PR 317 for opencode-adaptive-thinking; added one YAML plugin entry, validation passed, and the PR targets awesome-opencode:main
+tags: []
+title: PR 317 Plugin Entry Added
+updatedAt: '2026-04-26T09:22:13.684Z'
+---
+## Reason
+Record the successful awesome-list contribution and validation outcome
+
+## Raw Concept
+**Task:**
+Document the PR work for contributing the opencode-adaptive-thinking plugin to awesome-opencode
+
+**Changes:**
+- Created a minimal validated plugin entry at data/plugins/opencode-adaptive-thinking.yaml
+- Pushed the branch to the fork and opened PR 317
+- Confirmed the contribution workflow targets awesome-opencode:main
+
+**Flow:**
+inspect metadata -> branch from upstream/main -> add YAML plugin entry -> validate -> push -> open PR
+
+**Timestamp:** 2026-04-26T09:22:07.428Z
+
+**Author:** assistant
+
+## Narrative
+### Structure
+The work was performed in a local fork checkout of awesome-opencode, using a single YAML file under data/plugins/ as the contribution unit. The branch was kept focused to one commit and no direct README.md edit was needed because README generation is handled by the repository workflow.
+
+### Dependencies
+Required the awesome-list contribution format and local validation with npm run validate before opening the PR.
+
+### Highlights
+The PR was opened successfully as pull request 317, validation passed, and the contribution was kept minimal and isolated to the plugin YAML entry.
+
+## Facts
+- **reasoning_effort**: Reasoning effort was set to high [preference]
+- **fork_checkout_path**: A local fork checkout already existed at /Users/ianpascoe/code/awesome-opencode [project]
+- **awesome_list_contribution_format**: The contribution format uses one YAML file under data/plugins/ and does not require a direct README.md edit [project]
+- **validation_status**: The added plugin entry validated locally with npm run validate [project]
+- **pull_request_url**: Opened PR https://github.com/awesome-opencode/awesome-opencode/pull/317 [project]
+- **pull_request_target**: The PR targets awesome-opencode:main [project]
+- **commit_scope**: The branch contained one focused commit adding only data/plugins/opencode-adaptive-thinking.yaml [project]
