add-language

Role: the language meta-skill. Generate a draft write- recipe from the skeleton for a language outside the curated set (C, Zig, Clojure, Elixir), and wire it into the descriptor.

Prerequisites

~/.agentic-sdk/<project>/project.edn exists (run bootstrap-project first). The new language is outside the curated four (C, Zig, Clojure, Elixir). A real project need for the language, not speculative.

Procedure

Follow the shared add-* procedure in docs/design.md section 8.3: detect the gap, interview for the skeleton's variable slot, generate against the skeleton, wire into the descriptor, validate.

1. Detect the gap. Confirm the language is outside #{:c :zig :clojure :elixir} and that the project actually ships code in it. A speculative add is a finding, not an action.
2. Interview for the discipline slot. Ask one batch of at most three questions for what the write- skeleton's discipline slot needs: how the language expresses Functional Core / Imperative Shell, the failure model (errors as values, exceptions, result types), and the rigor that distinguishes correct code in this language (allocation, lifetimes, concurrency, the native edge when applicable). The skeleton fills four anchors and a numbered procedure per docs/design.md section 6; the discipline slot is the only part that varies.
3. Generate the recipe. Author skills/write-<lang>/SKILL.md from the skeleton: frontmatter (name: write-<lang>, model-invoked), the four anchors (the style-standard file, the architecture contract in skills/shared/references/architecture.md, the placement source from the descriptor's module map, the ADR log), and the numbered procedure (place it, then language discipline, then failure model, then verify like the lanes). Tests-first; terse comments; the public-text rule from skills/shared/references/prose-style.md. Reference FC/IS and the native-edge doctrine in architecture.md instead of restating them.
4. Wire the descriptor. Add the language keyword to :languages in ~/.agentic-sdk/<project>/project.edn. If the language brings a native edge, set :architecture :native-edge? true and add the native-edge citation. Add the language's lane commands to :lanes :cheap, :wave, and :pre-land (formatter, build, test, release gate).
5. Validate. Run one sample write and one review round using the new recipe: a writer writes a small unit, a reviewer runs the active dimensions over it. The recipe earns its place when the unit lands clean and the review finds nothing the recipe should have caught. Adjust the discipline slot from what the validation surfaced.
6. Land. One commit, category Skills:.

Boundaries

Produces one project-local recipe under $AGENTIC_SDK_SRC/skills/, snapshotted and owned by the project. The recipe is a candidate for promotion to a toolkit master via incorporate-feedback; promotion is deliberate, never automatic. Does not modify the curated four. Amends only the descriptor and adds only the one recipe file. Atoms referenced: the write- skeleton (docs/design.md section 6), skills/shared/references/architecture.md, skills/shared/references/prose-style.md, the project descriptor. Validation dispatches a writer (loading the new recipe) and a reviewer (running check-* dimensions).

Return

One line: the new recipe path, the descriptor field amended, and the validation verdict.
