P1 - Critical / Security

Security Hardening

• SEC-001: API key hashing uses SHA-256 without salt (FIXED 2026-01-29)

  • Location: Models/AgentApiKey.php::generate()
  • Risk: Weak credential storage vulnerable to rainbow table attacks
  • Fix: Switched to password_hash() with Argon2id
  • Note: findByKey() now iterates active keys since Argon2id uses unique salts
  • Added verifyKey() method for single-key verification

• SEC-002: SQL injection risk in TaskCommand orderByRaw (FIXED 2026-01-29)

  • Location: Console/Commands/TaskCommand.php
  • Risk: orderByRaw("FIELD(priority, ...)") pattern vulnerable if extended
  • Fix: Replaced with parameterised orderByPriority() and orderByStatus() scopes
  • Also fixed PlanCommand.php with same pattern

• SEC-003: StateSet tool lacks workspace scoping (FIXED 2026-01-29)

  • Location: Mcp/Tools/Agent/State/StateSet.php
  • Risk: Plan lookup by slug without workspace constraint - cross-tenant data access
  • Fix: Added workspace_id context check and forWorkspace() scoping to:
    • StateSet.php, StateGet.php, StateList.php
    • PlanGet.php, PlanList.php
  • Added ToolDependency for workspace_id requirement

• SEC-004: Missing rate limiting on MCP tool execution

  • Location: Services/AgentToolRegistry.php::execute()
  • Risk: API key rate limits apply to auth, not individual tool calls
  • Fix: Add per-tool rate limiting in execute() method
  • Acceptance: Tool execution respects rate limits per workspace

Input Validation

• VAL-001: Template variable injection vulnerability
  • Location: Services/PlanTemplateService.php::substituteVariables()
  • Risk: Special characters in variables could corrupt JSON structure
  • Status: Partially fixed with escapeForJson, but needs additional input sanitisation
  • Fix: Validate variable values against allowed character sets
  • Acceptance: Malicious variable values rejected with clear error

P2 - High Priority

Test Coverage (Critical Gap)

• TEST-001: Add AgentApiKey model tests (FIXED 2026-01-29)

  • Created tests/Feature/AgentApiKeyTest.php using Pest functional syntax
  • Created tests/Pest.php for Pest configuration with helper functions
  • Covers: key generation with Argon2id, validation, permissions, rate limiting, IP restrictions
  • Additional coverage: key rotation, security edge cases
  • 70+ test cases for comprehensive model coverage

• TEST-002: Add AgentApiKeyService tests (FIXED 2026-01-29)

  • Created tests/Feature/AgentApiKeyServiceTest.php using Pest functional syntax
  • Covers: authenticate(), IP validation, rate limit tracking, key management
  • 58 test cases including full authentication flow and edge cases

• TEST-003: Add IpRestrictionService tests (FIXED 2026-01-29)

  • Created tests/Feature/IpRestrictionServiceTest.php using Pest functional syntax
  • Covers: IPv4/IPv6 validation, CIDR matching (all prefix lengths), edge cases
  • 78 test cases for security-critical IP whitelisting

• TEST-004: Add PlanTemplateService tests (FIXED 2026-01-29)

  • Created tests/Feature/PlanTemplateServiceTest.php using Pest functional syntax
  • Covers: template listing, retrieval, preview, variable substitution, plan creation, validation, categories, context generation
  • 47 test cases organised into 9 describe blocks with proper beforeEach/afterEach setup

• TEST-005: Add AI provider service tests (FIXED 2026-01-29)

  • Created tests/Unit/ClaudeServiceTest.php - Anthropic Claude API tests
  • Created tests/Unit/GeminiServiceTest.php - Google Gemini API tests
  • Created tests/Unit/OpenAIServiceTest.php - OpenAI API tests
  • All use mocked HTTP responses, cover generate/stream/retry/error handling

Missing Database Infrastructure

• DB-001: Missing agent_plans table migration (FIXED 2026-01-29)

  • Created Migrations/0001_01_01_000003_create_agent_plans_tables.php
  • Creates: agent_plans, agent_phases, agent_workspace_states tables
  • Adds agent_plan_id FK and related columns to agent_sessions
  • Includes proper indexes for slug, workspace, and status queries

• DB-002: Missing indexes on frequently queried columns

  • agent_sessions.session_id - frequently looked up by string
  • agent_plans.slug - used in URL routing
  • workspace_states.key - key lookup is common operation

Error Handling

• ERR-001: ClaudeService stream() lacks error handling

  • Location: Services/ClaudeService.php::stream()
  • Issue: No try/catch around streaming, could fail silently
  • Fix: Wrap in exception handling, yield error events

• ERR-002: ContentService has no batch failure recovery

  • Location: Services/ContentService.php::generateBatch()
  • Issue: Failed articles stop processing, no resume capability
  • Fix: Add progress tracking, allow resuming from failed point

---

P3 - Medium Priority

Developer Experience

• DX-001: Missing workspace context error messages unclear

  • Location: Multiple MCP tools
  • Issue: "workspace_id is required" doesn't explain how to fix
  • Fix: Include context about authentication/session setup

• DX-002: AgenticManager doesn't validate API keys on init

  • Location: Services/AgenticManager.php::registerProviders()
  • Issue: Empty API key creates provider that fails on first use
  • Fix: Log warning or throw if provider configured without key

• DX-003: Plan template variable errors not actionable

  • Location: Services/PlanTemplateService.php::validateVariables()
  • Fix: Include expected format, examples in error messages

Code Quality

• CQ-001: Duplicate state models (WorkspaceState vs AgentWorkspaceState)

  • Files: Models/WorkspaceState.php, Models/AgentWorkspaceState.php
  • Issue: Two similar models for same purpose
  • Fix: Consolidate into single model, or clarify distinct purposes

• CQ-002: ApiKeyManager uses Core\Api\ApiKey, not AgentApiKey

  • Location: View/Modal/Admin/ApiKeyManager.php
  • Issue: Livewire component uses different API key model than services
  • Fix: Unify on AgentApiKey or document distinction

• CQ-003: ForAgentsController cache key not namespaced

  • Location: Controllers/ForAgentsController.php
  • Issue: Cache::remember('agentic.for-agents.json', ...) could collide
  • Fix: Add workspace prefix or use config-based key

Performance

• PERF-001: AgentPhase::checkDependencies does N queries

  • Location: Models/AgentPhase.php::checkDependencies()
  • Issue: Loops through dependencies with individual find() calls
  • Fix: Eager load or use whereIn for batch lookup

• PERF-002: AgentToolRegistry::forApiKey iterates all tools

  • Location: Services/AgentToolRegistry.php::forApiKey()
  • Issue: O(n) filter on every request
  • Fix: Cache permitted tools per API key

---

P4 - Low Priority

Documentation Gaps

• DOC-001: Add PHPDoc to AgentDetection patterns

  • Location: Services/AgentDetection.php
  • Issue: User-Agent patterns undocumented
  • Fix: Document each pattern with agent examples

• DOC-002: Document MCP tool dependency system

  • Location: Mcp/Tools/Agent/ directory
  • Fix: Add README explaining ToolDependency, context requirements

Feature Completion

• FEAT-001: Session cleanup for stale sessions

  • Issue: No mechanism to clean up abandoned sessions
  • Fix: Add scheduled command to mark stale sessions as failed
  • Criteria: Sessions inactive >24h marked as abandoned

• FEAT-002: Plan archival with data retention policy

  • Issue: Archived plans kept forever
  • Fix: Add configurable retention period, cleanup job

• FEAT-003: Template version management

  • Location: Services/PlanTemplateService.php
  • Issue: Template changes affect existing plan references
  • Fix: Add version tracking to templates

Consistency

• CON-001: Mixed UK/US spelling in code comments

  • Issue: Some comments use "organize" instead of "organise"
  • Fix: Audit and fix to UK English per CLAUDE.md

• CON-002: Inconsistent error response format

  • Issue: Some tools return ['error' => ...], others ['success' => false, ...]
  • Fix: Standardise on single error response format

---

P5 - Nice to Have

Observability
