Add perspective: Model-Agnostic vs Single-Model Coding Tools - #77
Merged
Conversation
Argues the model menu is the wrong scorecard for comparing AI coding tools. The real axis is harness-model coupling: single-model tools (Claude Code) co-design the harness with one model for ceiling quality, while model-agnostic tools (Cursor) abstract the model for optionality, cost control, and supply-risk insulation -- benefits that accrue mostly to the vendor. Grounded in the 2025-2026 Windsurf cutoff, Anthropic's commercial-terms enforcement, and Cursor's Composer pivot.

Attribute the Windsurf notice window and the Cursor competitor-block to reporting rather than stating them as confirmed fact, per the wiki's verification standard. Both trace to secondary outlets.
Prevents the over-read that model-agnostic means a thin harness everywhere. The penalty falls on third-party models routed through the generic interface; a model the vendor builds itself is co-designed with the harness, with Composer as the clearest case. Kept qualitative, no secondary-sourced model specifics.
- Convert the two Related Reading cross-links from plain relative paths to Hugo relref shortcodes, matching the convention used everywhere else in the perspectives section and gaining build-time link checking.

Summary
Adds a Perspectives piece comparing model-agnostic coding tools (Cursor) with single-model ones (Claude Code), plus an index entry. Weight 5.
The position it takes
The "more models = better" framing scores the wrong thing. The piece argues the real axis is harness-model coupling:
Includes a "when each wins" table and a closing argument that the two camps are converging (agnostic tools building their own models, model makers shipping their own harnesses).
Grounding
Uses the 2025-2026 events researched this week: the June 2025 Windsurf first-party Claude cutoff, the January 2026 commercial-terms (D.4) enforcement that blocked a rival lab via Cursor, and Cursor's Composer pivot. These are characterized qualitatively; no shaky third-party performance numbers are asserted as fact.
