Project instructions

LLM-specific project documentation lives in .agents/docs/.

Read the relevant files before making changes:

• .agents/docs/repository.md — repository-wide conventions including language
• .agents/docs/code-style.md — naming and code-style conventions
• .agents/docs/commits.md — commit message and commit workflow conventions
• .agents/docs/eck-lang/crate-structure.md — common crate and operation layout
• .agents/docs/eck-lang/adaptive-integer-arrays.md — intended direction for adaptive int[] storage and vectorized execution (design note, not current semantics)
• .agents/docs/eck-lang/use-cases.md — language use-case test conventions
• .agents/docs/eck-lang/performance.md — raw execution speed as the primary implementation goal
• .agents/docs/eck-lang/syntax/array-declaration.md — array literals, element constraints, indexing, mutation, and rendering
• .agents/docs/eck-lang/syntax/array-end-operations.md — adding and removing values at either end of a mutable array, including the aliases and the empty-array contract
• .agents/docs/eck-lang/syntax/conditionals.md — current if, else if, and else syntax, including mandatory condition parentheses
• .agents/docs/eck-lang/syntax/for.md — current integer range for loop syntax and behavior
• .agents/docs/eck-lang/syntax/variable-declaration.md — variable declaration syntax, mutability, type inference, and nullability
• .agents/docs/eck-lang/syntax/while.md — current while loop syntax, condition requirements, and control flow
• .agents/docs/eck-lang/variable-scope.md — binding, scope, shadowing, and control-flow scope semantics
• .agents/docs/tests.md — testing conventions, structure, and requirements

When a task modifies files under .agents/docs/, review this index as part of that task and update it if any path or description is no longer accurate. Do not perform this synchronization check for tasks that do not modify .agents/docs/.

The documentation in .agents/docs/ is authoritative.

Follow the relevant documentation exactly and do not invent alternative project conventions when they are already defined there.

When implementing or changing a feature that affects language syntax, read the relevant documentation under .agents/docs/eck-lang/syntax/ first. The implementation and its tests must conform to the documented syntax, even when the existing implementation accepts a conflicting form.
