OPAM OCaml Skill

Trit: -1 (MINUS - package constraint verification)
Foundation: OPAM + OCaml + dune

Core Concept

OPAM manages OCaml development:

• Compiler switches (versions)
• Package dependencies
• Build system integration
• Repository management

Common Commands

# Switch management
opam switch create 5.1.0
opam switch list
opam switch 5.1.0

# Package operations
opam install dune merlin ocaml-lsp-server
opam upgrade
opam remove <pkg>

# Environment
eval $(opam env)

# Repository
opam repo add coq-released https://coq.inria.fr/opam/released

Dune Integration

GF(3) Integration

type trit = Minus | Ergodic | Plus

let trit_of_build_status = function
  | Build_error _ -> Minus
  | Build_warning _ -> Ergodic
  | Build_success -> Plus

let gf3_conserved trits =
  let sum = List.fold_left (fun acc t ->
    acc + match t with Minus -> -1 | Ergodic -> 0 | Plus -> 1
  ) 0 trits in
  sum mod 3 = 0

Canonical Triads

opam-ocaml (-1) ⊗ nickel (0) ⊗ geb (+1) = 0 ✓
opam-ocaml (-1) ⊗ lispsyntax-acset (0) ⊗ free-monad-gen (+1) = 0 ✓

Scientific Skill Interleaving

This skill connects to the K-Dense-AI/claude-scientific-skills ecosystem:

Graph Theory

• networkx [○] via bicomodule
  • Universal graph hub

Bibliography References

• general: 734 citations in bib.duckdb

SDF Interleaving

This skill connects to Software Design for Flexibility (Hanson & Sussman, 2021):

Primary Chapter: 5. Evaluation

Concepts: eval, apply, interpreter, environment

GF(3) Balanced Triad

opam-ocaml (+) + SDF.Ch5 (−) + [balancer] (○) = 0

Skill Trit: 1 (PLUS - generation)

Secondary Chapters

• Ch4: Pattern Matching
• Ch2: Domain-Specific Languages
• Ch7: Propagators

Connection Pattern

Evaluation interprets expressions. This skill processes or generates evaluable forms.

Cat# Integration

This skill maps to Cat# = Comod(P) as a bicomodule in the equipment structure:

Trit: 0 (ERGODIC)
Home: Prof
Poly Op: ⊗
Kan Role: Adj
Color: #26D826

GF(3) Naturality

The skill participates in triads satisfying:

(-1) + (0) + (+1) ≡ 0 (mod 3)

This ensures compositional coherence in the Cat# equipment structure.
