Work directly in:

/home/kernel-kain/Documents/Github/unfinished-business

Execution rules:

1. Work only on the main branch.
2. Begin with:
   • git status
   • git switch main
   • git pull --ff-only origin main
3. Preserve all unrelated changes, untracked files, and existing stashes. Do not apply, delete, or commit .backboard/, .unfinished-business/, .env files, credentials, or the existing stash unless this phase explicitly requires it.
4. Read the relevant source, tests, AGENTS.md files, and documentation before editing.
5. Implement only the phase described below. Do not begin the next phase.
6. Maintain backward compatibility with existing saved projects through explicit migrations.
7. Do not expose provider secrets, prompts containing secrets, or private model output in logs, telemetry, screenshots, or error messages.
8. Add or update tests for every behavior changed.
9. After implementation, update the relevant project documentation, including:
   • README.md when user-facing behavior changes
   • docs/ARCHITECTURE.md
   • docs/DECISIONS.md
   • docs/IMPLEMENTATION_PLAN.md
   • docs/EVIDENCE.md
   • docs/RELEASE_NOTES.md
   • any phase-specific setup or integration documentation
10. Mark the phase complete in the implementation plan only after its acceptance criteria pass.
11. Run all relevant verification. At minimum:

• npm run typecheck
• npm test
• npm run build Run visual, security, budget, contract, migration, or integration tests when affected.

1. Review the final git diff for accidental files, secrets, debugging output, and unrelated changes.
2. Commit with the commit message specified by this phase.
3. Push the commit to origin/main. Never force-push.
4. If the push is rejected because origin/main advanced, fetch and rebase safely, resolve only scoped conflicts, rerun verification, and push normally.
5. Finish with:

• implementation summary
• changed files
• documentation updated
• tests and results
• known limitations
• commit hash
• push result

Do not stop for ordinary implementation decisions. Stop only if there is a destructive conflict, missing required credential, irreconcilable remote conflict, or a decision that would materially change the product’s intended behavior.

The Code Mode tool catalog has changed. This catalog supersedes the previous Code Mode tool catalog.

Code Mode

The tools listed below, and search, cannot be called directly: they only work as JavaScript inside the execute tool. Every other tool you have is a normal tool call: call it directly, never inside execute.

The catalog is partial. Before calling a tool that is not listed below, find it with the global search(...) function. Do not guess tool names. Each result's path is the complete call expression: write it out as code, for example await tools.ns.tool_name({ ... }). Do not use it as a key such as tools[path].

• search({ query?: string, namespace?: string, /** @integer @exclusiveMinimum 0 / limit?: number, /* @integer @minimum 0 / offset?: number, }): { items: Array<{ path: string, description: string, signature: string, }>, /* @integer @minimum 0 / remaining: number, next: { /* @integer @minimum 0 */ offset: number, } | null, }

Code Mode tools (call only inside execute)

Implement Phase 1: allow every model available through OpenCode and replace generic provider errors with actionable messages.

Objectives:

• Remove the free/local-only product restriction.
• Permit any model OpenCode reports as available to the connected user.
• Add user-controlled cost safeguards.
• Explain provider privacy, authentication, quota, and availability errors clearly.

Implementation requirements:

1. Remove the assertFreeOrLocal selection restriction from the normal model-selection path.
2. Do not invent models or silently substitute a different model.
3. Add model access preferences:
   • All accessible models
   • Free and local only
4. Default new projects to All accessible models, matching the requested behavior.
5. Replace the hardcoded $0 budget behavior with:
   • optional session spending limit;
   • an unlimited/disabled state;
   • explicit handling for models whose prices are unknown.
6. Require an informed confirmation before the first paid or unknown-price request when the user has not already accepted that policy.
7. Display useful model metadata:
   • provider;
   • local/remote;
   • free/paid/unknown pricing;
   • context and output limits;
   • variant;
   • relevant privacy warning.
8. Introduce a structured provider error type with categories:
   • PROVIDER_DATA_POLICY
   • PROVIDER_AUTH
   • PROVIDER_RATE_LIMIT
   • PROVIDER_QUOTA
   • MODEL_UNAVAILABLE
   • MODEL_CONTEXT_LIMIT
   • PROVIDER_TEMPORARY
   • UNKNOWN_PROVIDER_FAILURE
9. Preserve safe provider details, status codes, and session references while redacting secrets.
10. Replace generic concatenated error text with an error card containing:
    • what happened;
    • whether saved work changed;
    • recommended repair;
    • retry/change-model action;
    • technical details disclosure.
11. Add a specific explanation for provider routes rejected because they train on request data or conflict with workspace privacy settings.
12. Update model-selection, budget, provider-error, redaction, and migration tests.

Acceptance criteria:

• Paid, free, local, and unknown-price models reported as available can be selected under the appropriate policy.
• Free/local-only mode still blocks other models intentionally.
• No paid request is silently made.
• Provider privacy rejection produces a useful repair action.
• Generic provider failures retain a safe diagnostic reference.
• Existing model selections migrate correctly.
