Resolves #164
## Changes
### Agent Files (16 files)
- Migrated all agent frontmatter from deprecated `permissions:` (plural) to `permission:` (singular)
- Updated: core agents (OpenCoder, OpenAgent, RepoManager)
- Updated: code subagents (TestEngineer, CoderAgent, BuildAgent, CodeReviewer)
- Updated: core subagents (TaskManager, DocWriter, ExternalScout, ContextScout, ContextManager, Context Retriever)
- Updated: development subagents (DevOpsSpecialist, FrontendSpecialist)
- Updated: system-builder subagents (ContextOrganizer, WorkflowDesigner)
### Context Documentation (3 files)
#### Updated: agent-frontmatter.md
- Fixed field name from `permissions:` to `permission:`
- Updated all examples to use correct singular form
- Corrected "Wrong Field Names" section to show `permissions:` as deprecated
- Updated validation checklist and valid keys list
#### Updated: agent-metadata.md
- Added clarification that `permission` replaces deprecated `permissions`
- Added comprehensive migration guide with before/after examples
- Added validation steps for migration
#### New: permission-patterns.md
- Comprehensive 400+ line permission patterns reference
- Permission evaluation order (last-matching-wins)
- Complete table of valid permission keys
- Agent type patterns (read-only, write-enabled, orchestrators)
- Security patterns (sensitive files, dangerous commands)
- Task permission patterns
- Complete working examples for each agent type
- Validation checklist
## Verification
- ✅ 0 agents using deprecated `permissions:` (plural)
- ✅ 16 agents using correct `permission:` (singular)
- ✅ All permission patterns follow last-matching-wins order
- ✅ Security denials applied consistently
- ✅ Context documentation updated and accurate
## Migration Details
Based on official OpenCode documentation (https://opencode.ai/docs/agents/):
- OpenCode v1.1.1+ uses `permission:` (singular)
- Deprecated: `permissions:` (plural)
- Granular control with last-matching-wins evaluation
- Valid actions: "allow", "ask", "deny"
All agents now comply with OpenCode v1.1.1+ standards.
* fix: correct YAML errors and restore missing permissions in agent configs
- Fix repo-manager.md duplicate permission section
- Fix externalscout.md YAML indentation error
- Remove old tools: section from devops-specialist.md
- Restore context file permissions in context-manager.md
- Restore test command permissions in tester.md
- Clean up formatting in coder-agent.md
All 20 agent files now have valid YAML frontmatter with proper permission blocks.
* fix: standardize permission key across agent files
- Updated all instances of `permissions:` to `permission:` in agent frontmatter for consistency.
- Removed deprecated `write:` and `edit:` sections from externalscout.md.
- Adjusted related documentation to reflect the singular form of permission key.
These changes ensure compliance with OpenCode v1.1.1+ standards and improve YAML structure across the repository.
