fix(skills): correct launcher environment approval classification

[alwaysmavs]

Summary

Skill launchers that start with export PATH="...:$PATH"; cd ...; BUN_BE_BUN=1 oo ... were rejected as environment dumps. Treat plain export assignments as ordinary local work while preserving checks on subsequent commands, executable substitutions, sensitive resources, and managed runtime overrides.

• Inspect compound commands and nested shell wrappers for environment dumps and protected OO mutations.
• Add specific denial reasons to local-access decisions and metadata-only diagnostics.
• Update GPT Image 2 runtime-copy guidance to reuse the inherited PATH and pass WANTA_OO_BIN through the runner's --oo option.
• Add regression coverage for the image-runner command shape, adapter parity, and protected operations; document the behavior.

Verification

• corepack pnpm run ts-check
• corepack pnpm run lint (entire repository)
• corepack pnpm run format
• corepack pnpm test
• corepack pnpm run build
• Runtime/UI verification completed or not applicable

Targeted verification: 206 tests passed across command policy, local-access policy, chat service, permission diagnostics/state, renderer permission helpers, ACP/external command environments, and GPT Image 2 runtime compatibility. Changed files were formatted and git diff --check passed.

Started the development app with corepack pnpm run dev; Electron and the agent sidecar started successfully, then the dev process was stopped. Startup also reported a knowledge database schema migration warning. A real image-generation end-to-end run was not performed. The full test suite, full format check, and production build were not run.

Safety and Compatibility

• Local BYOK and signed-in OOMOL modes were considered separately.
• No credential was exposed to the renderer, logs, fixtures, screenshots, or committed files.
• Agent tools, permissions, and system prompts remain aligned, or the change does not affect them.
• Migration, packaging, endpoint, and update implications were considered.
• Relevant documentation and tests were updated.

The shared local-access policy keeps adapter parity and does not depend on model-provider authentication. Environment dumps, credential references, and managed runtime mutations remain blocked, including in full-access mode. Consequential commands still require confirmation in default mode. No Skill-directory trust exemption or credential/endpoint changes were introduced. Runtime guidance is applied only to Wanta's private Skill copy; no data migration is required.

Summary by CodeRabbit

• Bug Fixes

  • Environment-variable setup commands are handled safely without weakening checks on subsequent or wrapped commands.
  • Environment dumps and commands containing executable substitutions, credential changes, or configuration mutations remain blocked.
  • Automatic access decisions now record accurate, stable denial reasons without exposing command arguments or credentials.

• Documentation

  • Updated guidance for managed image-generation tools to reuse the provided command environment and executable settings, including support for the runner’s --oo option.

Walkthrough

The permission classifier now permits plain environment assignments while continuing to deny environment dumps and unsafe shell syntax. Structured denial reasons flow through local access decisions into diagnostic logs without exposing command values. Tests cover wrapped commands, consequential suffixes, and reason metadata. GPT Image 2 runtime guidance now reuses inherited environment variables and forwards WANTA_OO_BIN through the runner option.

Merge Risk: 🔵 Low · up to b5020

Skill command guidance can incorrectly imply that protected environment assignments receive ordinary local access. Document the exception before merge.

- Around line 88-93: Update the shell setup guidance near the Managed Skill
section to explicitly state that the export NAME=value exception applies only to
unprotected assignments; assignments containing OO_API_KEY or OO_CONNECTOR_TOKEN
remain denied as credential_reference, and OO_ENDPOINT assignments remain denied
as runtime_environment_override. Preserve the existing blocking rules for
environment dumps and executable shell syntax.
