Add or change generated build and value-test verification in tslc. Use when asked to support a compiler or toolchain command, target triple or linker, runner or emulator, compiler or target preflight, cross-compilation path, verifier backend driver, missing-tool skip, command report, or generated verification capability independent of adding a backend.
Add a target extension or machine-profile family through TSL source data, typed compiler capabilities, generated artifacts, verification, and tests. Use when asked to add a SIMD ISA or extension, fixed or scalable profile, compiler-vector overlay, target family, machine profile, feature or compile mode, or the first primitive slice for a new target.
Extend typed generated value-test planning and rendering in tslc. Use when asked to support a new authored tests shape or signature, add a case kind or pattern, handle memory, mask, conversion, scalable, or differential cases, resolve authored_unplanned or backend_unsupported coverage, or add backend rendering for a planned case.
Add a TSIL keyword region to tslc. Use when asked to recognize a new TSIL keyword, validate region shell syntax, lower a new body island, support nested TSIL regions, or replace raw implementation text with typed TSIL semantics.
Add, complete, or refactor a specialization of an existing TSL primitive. Use when asked to add an implementation body for a specific extension, profile, type group, or backend; replace scattered intrinsic recipes with semantic TSL-primitive composition; close a missing coverage slot; or fix generated build/value-test gaps in existing primitive source data.
Add or update a TSL primitive in tsldata and the tslc compiler. Use when asked to add a new primitive, change primitive signatures/tests/bodies, support a new primitive shape, or make primitive source data compile through parsing, validation, selection, lowering, rendering, and generated value tests.
Add a backend or backend capability to tslc. Use when asked to introduce a new generated language/backend, register backend IDs or capabilities, add backend-specific type/value/intrinsic translation, add backend render assets, or make backend support additive and validated.
Review tslc design health and detect drift from the repository and compiler charters, scoped AGENTS.md files, PLANS.md, and tslc/DESCRIPTION.md. Use when asked for a design review, architecture drift audit, extensibility review, maintainability review, KISS/DRY review, or pre/post-check after adding primitives, TSIL regions, backend support, or major compiler pipeline changes.
