WalkthroughThe package now supports OpenCode v2 through a new adapter while preserving versioned v1 runtime and TUI integrations. It adds v2 tool, memory, shell, event, command, and message handling, updates capabilities and exports, and expands compatibility tests. ChangesOpenCode compatibility
Estimated code review effort: 5 (Critical) | ~90+ minutes Merge Risk: 🟠 High · up to The package root and TUI now support a second plugin API, but the current implementation still has unresolved risks that can stall prompts, grow memory indefinitely, duplicate or lose stored conversations, break tools, create duplicate remote sessions, and expose personal data in logs. The PR is not merge-ready until these paths are fixed or explicitly accepted by owners. Sequence Diagram(s)sequenceDiagram

globalSettingsPathandsharedConfigPathare identical. Two names for one path invite drift, because a later change can update one helper and miss the other. This file already uses both interchangeably for the same file, at line 63 and line 77.The fallback also differs from the runtime.
src/v1/index.tsline 580 resolves the home directory asprocess.env.HOME || process.env.USERPROFILE || process.cwd(). This file useshomedir()as the final fallback. If neither environment variable is set, the runtime reads./.honcho/config.jsonwhile the TUI writes~/.honcho/config.json. The TUI then persists settings that the runtime never reads.Export one shared helper and use the same fallback in both modules.

In `@src/capabilities.ts`:
- Around line 4-8: Update HOST_CAPABILITIES to reflect actual support: scope
structured_question_ui to v1 unless native v2 dialog support is implemented, and
mark persistent_background_runtime unsupported when restart persistence is
required because sessionStates and v1InstancesByDirectory are process-local.
Document HOST_CAPABILITIES_VERSION as the manifest schema version, distinct from
the OpenCode API version.
In `@src/index.ts`:
- Around line 262-289: Fix message deduplication in the context hook: replace
the Date.now()-based fallback with a stable key derived from the message/session
content, and only add the key to capturedMessageIds after chat.message succeeds
so failed writes can retry. Bound capturedMessageIds per session to prevent
unbounded plugin-lifetime growth, while preserving successful message delivery.
- Around line 216-234: Wrap the event subscriber callback body in a try/catch so
rejections from getV1Instance or instance.event are contained and cannot become
unhandled promise rejections or disrupt the host process. Keep the existing
event mapping, directory lookup, and early returns unchanged, and handle the
caught error using the module’s established error-reporting mechanism.
- Around line 129-137: Update getV1Instance to cache the pending
runtime-creation promise in v1InstancesByDirectory before awaiting it, so
concurrent callers for the same directory share one
createV1PluginInput/makeHooks operation and receive the same resolved instance.
- Around line 147-156: Replace the zodToJsonSchema conversion in the tool
transformation loop with Zod 4’s native z.toJSONSchema(argsSchema) while
retaining the existing z.object(definition.args) construction and tool
registration behavior.
Apply the same fix in `@package.json` around lines 45 - 47: The dependency and
package-level remediation are covered by the consolidated finding.
In `@src/v1/index.ts`:
- Around line 1032-1041: Bound the state retained by getState: add a maximum
sessionStates capacity with least-recently-used eviction, updating recency on
access while preserving the existing session.deleted/session.error cleanup. Also
cap capturedAssistantMessageIds within each SessionState and prune its oldest
entries when the per-session limit is exceeded.
- Around line 1154-1184: In hydrateSessionStartContext, add a shared deadline to
each Honcho promise passed to Promise.allSettled, including both context calls,
summaries, and conditional chat calls, so timed-out sections become rejected and
are handled as missing. Apply the same timeout behavior to the Honcho request
used by refreshPromptContext through runtime.session.context, reusing a single
timeout helper and constant rather than duplicating timer logic.
- Around line 1277-1282: Update the durable conclusion log call to remove the
full content field, retaining only identifying metadata and a length value for
the conclusion. Preserve the existing session identifiers, reason, and “Durable
Honcho conclusion created.” message while replacing content with its length.
- Around line 1287-1293: Filter discarded event types in the event hook before
calling deriveRuntimeHandle, especially command.executed and other branches that
do not use the handle. Cache resolveSettings results for the hook’s short
lifetime to avoid repeated config reads and parsing. Update withRuntime and

of deriving it twice.

try/catch, preserving the existing success dialog on completion. In the catch
path, show a failure alert using the same error-dialog pattern as
openModeValueDialog, including the caught error details and ensuring rejected
saves do not escape as unhandled promises.

🚀 Performance & Scalability | 🟠 Major | ⚡ Quick win
Read the config once per hook, and filter event types before deriving the handle.
deriveRuntimeHandle at line 776 calls resolveSettings, which calls ensureSharedGlobalSettings, which reads and parses the config file from disk on every call. Two problems follow.
First, line 1289 derives the handle before the event type checks at lines 1291-1318. The message.part.updated event fires for each streamed text part, so this performs a disk read and a JSON.parse for every chunk of every assistant response. The command.executed branch discards the handle entirely.
Second, withRuntime at line 1059 derives the handle, then line 1070 calls createActiveRuntime, which derives it again at line 869. Every guarded operation resolves the config twice.
Move the cheap type filter above the handle derivation, and cache the resolved settings.
⚡ Proposed reordering for the event hook
event: async ({ event }) => {
const payload = isRecord(event) ? { event, ...(isRecord(event.properties) ? event.properties : {}) } : { event }
- const handle = await deriveRuntimeHandle(pluginInput, payload, configPath)

if (event.type === "command.executed") {
return
}
+ const handle = await deriveRuntimeHandle(pluginInput, payload, configPath)
+ const stateKey = deriveSessionStateKey(handle)Also pass the already-derived handle into createActiveRuntime instead of re-deriving it, and add a short-lived cache around resolveSettings.

In `@src/v1/index.ts` around lines 1287 - 1293, Filter discarded event types in
the event hook before calling deriveRuntimeHandle, especially command.executed
and other branches that do not use the handle. Cache resolveSettings results for
the hook’s short lifetime to avoid repeated config reads and parsing. Update
withRuntime and createActiveRuntime to pass and reuse the already-derived
runtime handle instead of deriving it twice.

Thanks for making this PR! Excited by the changes introduced in V2 of Opencode. I have a few architecture questions and I want to wait until the v2 plugin API contract is explicitly finalized, but great to get a head start. Things are seeming pretty stable right now, so I expect to get this merged in soon. Left one comment for now. I'm sure more will come up in the next couple days. |
There was a problem hiding this comment.
A plain { id, server, setup } default export will do the same job as this file. (v1 reads server, v2 reads setup)

This PR adds OpenCode v2 plugin support while preserving the existing v1 entrypoints.
