🔴 (19:33) Core Tool Architecture directive: permission sources are “always constructed from the canonical invocation context” as { type: "tool" as const, messageID: context.messageID, id: context.id }. 🔴 (19:33) Core Tool Architecture directive: leaves own resolution, permission, and side-effect ordering; translate only expected typed errors into ToolFailure and do not use catchCause, because interruption and defects must survive. 🔴 (19:33) Core Tool Architecture directive: user declines from Permission.assert and question dismissals travel as defects beneath leaf mapError blankets, resurface as typed failures at SessionModelRequest.executeTool, and leaves must “never catch or convert them.” 🔴 (19:33) Core Tool Architecture states Permission.CorrectedError remains typed so a leaf converts a decline with feedback into ToolFailure and model execution continues. 🔴 (19:33) /home/byk/Code/opencode-v2-pilot/packages/core/src/tool/runtime.ts lines 28–44 define execute(tool, input, context): it decodes input, runs tool.execute(decoded, context), preserves an existing Tool.Error, and maps any other typed failure to new Tool.Error({ message: error instanceof globalThis.Error ? error.message : String(error) }). 🔴 (19:33) The execute(...) error normalization in /home/byk/Code/opencode-v2-pilot/packages/core/src/tool/runtime.ts enforces the declared Tool.Error contract at the untrusted plugin boundary; its Effect.mapError(...) does not touch defects used to tunnel declines or interruptions. 🔴 (19:33) /home/byk/Code/opencode-v2-pilot/packages/core/src/tool/runtime.ts has a synchronous jsonSchemas cache with capacity 100; cache lookup attempts jsonSchema(schema) and yields undefined if conversion fails. 🔴 (19:33) validateInput(...) in /home/byk/Code/opencode-v2-pilot/packages/core/src/tool/runtime.ts uses Standard Schema validation when applicable; otherwise it uses an Effect Schema directly or retrieves a converted codec from jsonSchemas, accepts the value unchanged when no codec can be produced, and decodes with { errors: "all" }. 🔴 (19:33) formatInputIssues(...) in /home/byk/Code/opencode-v2-pilot/packages/core/src/tool/runtime.ts includes at most the first 5 issues, renders numeric path segments as [index], uses root for an absent path, reports the exact remaining issue count, includes pretty-printed supplied arguments, and asks the model to update the arguments and call the tool again. 🔴 (19:33) jsonSchema(...) in /home/byk/Code/opencode-v2-pilot/packages/core/src/tool/runtime.ts selects JsonSchema.fromSchemaDraft07(...) when $schema contains "draft-07" or the document has definitions; otherwise it uses JsonSchema.fromSchemaDraft2020_12(...). 🔴 (19:33) /home/byk/Code/opencode-v2-pilot/packages/core/src/tool.ts lines 220–248 implement Tool.snapshot(permissions?): rules default to [], tools wholly disabled under tool.options?.permission ?? name are omitted, codemode === false tools become direct definitions sorted by effective name, and all other active tools form the CodeMode inventory. 🔴 (19:33) In Tool.snapshot(...), CodeMode is enabled only when permission action "execute" is not wholly disabled; when enabled, the snapshot includes CodeModeTool.catalog(codeModeInventory) and one definition(codeModeTool). 🔴 (19:33) Core Tool Architecture states codemode defaults to true; codemode: false retains a tool on the provider’s native tool list, while a namespace flattens direct model names to <namespace>_<tool>. 🔴 (19:33) Core Tool Architecture states the registry has no Permission.Service dependency and performs no execution authorization; registration permission options exist only for whole-tool definition filtering, most default to the effective tool name, and edit, write, and patch share the "edit" action. 🔴 (19:33) Core Tool Architecture states tool filtering controls catalog visibility rather than execution authorization; an admitted call still executes the captured leaf policy. 🔴 (19:34) /home/byk/Code/opencode-v2-pilot/packages/plugin/src/effect/plugin.ts defines Context with domains app, location, options, agent, aisdk, catalog, command, event, experimental.terminal, integration, mcp, generate, permission, plugin, reference, rpc, session, shell, skill, storage, tool, vcs, websearch, and worktree. 🔴 (19:34) /home/byk/Code/opencode-v2-pilot/packages/plugin/src/effect/plugin.ts defines Plugin<R = Scope.Scope> with readonly id: string and readonly effect: (context: Context) => Effect.Effect<void, never, R>; define<R = Scope.Scope>(plugin) returns the plugin unchanged. 🔴 (19:35) /home/byk/Code/opencode-v2-pilot/packages/schema/src/tool.ts defines Tool.Error as Schema.TaggedError tagged "Tool.Error" with required message: Schema.String, optional error: Schema.Defect(), and optional metadata: Schema.Record(Schema.String, Schema.Unknown). 🔴 (19:35) /home/byk/Code/opencode-v2-pilot/packages/schema/src/tool.ts defines Tool.TextContent as { type: "text", text: string }, Tool.FileContent as { type: "file", uri: string, mime: string, name?: string }, and Tool.Content as their "type"-tagged union. 🔴 (19:35) /home/byk/Code/opencode-v2-pilot/packages/schema/src/tool.ts defines Tool.Result<Output> with optional machine output, optional content as either a string or readonly Tool.Content[], and optional metadata. 🔴 (19:36) /home/byk/Code/opencode-v2-pilot/packages/core/src/tool/plugin/shell.ts constructs source inside ShellTool.prepare(invocation, context) from the canonical invocation fields context.messageID and context.id, then passes it to permission.assert(...) with sessionID, agent, action name, and command-derived resources/save values. 🔴 (19:36) ShellTool.prepare(...) resolves and canonicalizes invocation.cwd, scans the command using ShellParse.scan(...), authorizes the target and parsed external directories before permission assertion, and immediately before spawning verifies that the approved working directory still exists and is a directory. 🔴 (19:36) The shell tool uses input.timeout ?? 0 for background execution and input.timeout ?? DEFAULT_TIMEOUT_MS otherwise; it reports { shellID: info.id } through context.progress(...). 🔴 (19:36) Foreground shell waiting uses jobs.block(...) and cancels the job on interruption via Effect.onInterrupt(() => jobs.cancel(job.id).pipe(Effect.ignore)); a backgrounded result sets shell timeout to 0, schedules completion notification, and returns backgroundResult(...). 🔴 (19:36) The shell leaf maps typed execution errors at its outer leaf boundary to new ToolFailure({ message: \Unable to execute command: ${input.command}`, error })withEffect.mapError(...); defects carrying permission declines are not converted by this mapping. 🔴 (19:37) /home/byk/Code/opencode-v2-pilot/packages/core/src/tool.tslines 112–155 defineexecuteTool(...): it wraps successful runtime execution as { value }, catches only tagged "Tool.Error"into{ failure }, triggers tool.execute.afterwithstatus: "error"or"completed", and permits the after hook to mutate the returned error/result. 🔴 (19:37) On a failed tool execution, executeTool(...)supplies the after hook withtool, sessionID, agent, messageID, id, original input, status: "error", and error; after the hook it yields afterEvent.error. 🔴 (19:37) On successful tool execution, executeTool(...)supplies the after hook withstatus: "completed"and a result containing declaredoutputwhen present, normalizedcontent, and optional metadata; afterward it normalizes content and images again before returning. 🔴 (19:37) executeTool(...)catches onlyTool.Error, so permission-decline and question-cancellation defects bypass its error after-hook settlement path and continue to the Session model-request seam. 🔴 (19:37) /home/byk/Code/opencode-v2-pilot/packages/core/src/tool.tsregistration behavior:addvalidates then stores a copied tool undereffectiveName(tool); updatedoes nothing for a missing ID, preserves the existingname, id, and namespace, and leaves the prior definition intact when the updated registration is invalid. 🔴 (19:38) /home/byk/Code/opencode-v2-pilot/packages/ai/src/schema/errors.tsdefinesToolFailureas extending canonicalTool.Error; AI tool APIs require handler errors to be expressed as ToolFailure`, while unmapped errors and defects fail outside normal tool settlement.
