AL Planning Subagent¶


Agent ID	`al-planning-subagent`
Model	Claude Sonnet 4.5
Type	Internal · Research
Invoked by	AL Development Conductor
User-invocable	No

Purpose¶

AL-aware research and context gathering for Business Central development. Explores the codebase to understand object architecture, event patterns, extension structure, and dependencies. Returns structured findings to the Conductor for plan creation.

Research scope¶

Area	What it discovers
AL objects	Tables, Pages, Codeunits, Reports, Enums involved
Extensions	TableExtension, PageExtension, EnumExtension usage
Events	Existing subscribers/publishers, integration points
Project structure	AL-Go structure, app vs test separation
Performance	Large tables requiring SetLoadFields, filtering needs
Dependencies	`.alpackages/`, `app.json` dependencies, symbol references

Discovery pattern¶

1. Search for base object name (e.g., "Customer", "Sales Header")
2. Find TableExtensions of that object
3. Identify related Codeunits and event handlers
4. Check PageExtensions for UI impact
5. Review test codeunits for patterns
6. Map event subscribers/publishers

Constraints¶

Rule	Detail
No user interaction	Returns findings to Conductor only
No code writing	Research only — never creates/edits files
No decisions	Gathers data; Conductor makes the plan

Output¶

Structured research report with: objects found, patterns identified, risks, recommended approach, and ID ranges available.
