ObjectScript Semantic Navigation Skill

This skill provides strategies for mapping out ObjectScript codebases using the available MCP tools.

Discovery Strategy

1. Symbol Anchoring

Before editing, always locate the Symbol Anchor (the definition of the class or method you intend to change).

• Tool: iris_symbols(query) — searches the live IRIS namespace by name pattern (supports * wildcards)
• Tool: iris_symbols_local(workspace_path) — parses .cls files on disk via tree-sitter when IRIS is unavailable
• Strategy: Don't just search for the name; check the containerName to confirm you are in the correct package.

2. Dependency Tracing

When changing a signature, use Upstream Tracing to find every caller.

• Tool: docs_introspect(class_name) — fetches the full class definition from %Dictionary, including all methods, parameters, return types, and inheritance chain
• Tool: iris_symbols(query="ClassName.*") — list all members of a class
• Strategy: Read each caller's containing file with the Read tool before modifying. If a method is called from multiple packages, plan all edits before touching any file.

3. Hierarchical Exploration

ObjectScript heavily uses inheritance (Extends).

• Strategy: If a method is missing in the current file, check the Extends list.
• Tool: docs_introspect(class_name) — reveals the full inherited interface including superclass chain.
• Strategy: Run iris_symbols("SuperClass.*") to list members inherited from a superclass.

Bridging the Gap

When the model receives a list of symbols from iris_symbols, it should not just "see" a list. It should follow this reasoning:

1. "I see Package.Class:Method at line 10."
2. "I will now call docs_introspect('Package.Class') to confirm the method signature and see what it overrides."
3. "I will search for Package.Class with iris_symbols and Grep to find classes that Extend it."

Guidelines

• Never assume a symbol is unique until verified by iris_symbols.
• Always call docs_introspect on any class you did not write before editing it — the live definition may differ from what you can infer from filenames alone.
• Use Read to open .cls files on disk when you need line-level context around a symbol.
• Use Grep (regex across the workspace) when iris_symbols results are too broad.
