Skills (22)

• cmdliner

  Designing and implementing robust command-line interfaces using OCaml's cmdliner library. Use when Claude needs to: (1) Design a new CLI or subcommand layout, (2) Implement cmdliner terms and combinators, (3) Enforce clear, predictable, orthogonal options, (4) Produce high-quality --help output and

• code-style

  OCaml coding style and refactoring patterns. Use when the user asks to tidy, clean up, refactor, or improve OCaml code, reviewing code quality, enforcing naming conventions, or reducing complexity.

• doc-style

  OCaml comment and ocamldoc writing style, in the voice of a POSIX manual page. Use whenever writing, rewording, reviewing or deleting any OCaml comment or documentation. Triggers on ocamldoc, odoc, doc comments, (** ... *), .mli documentation, .mld pages, documenting a function, type or module, and

• dune-migration

  Migrating OCaml projects from ocamlbuild/topkg to dune. Use when discussing _tags files, .mllib files, pkg/pkg.ml, topkg, or build system migration.

• effects

  OCaml 5 algebraic effects design patterns. Use when Claude needs to: (1) Design APIs that interact with effect-based schedulers, (2) Decide between effects vs exceptions, (3) Integrate libraries with Eio or affect, (4) Handle suspension vs error cases in streaming code, (5) Understand the layered ef

• eio

  Eio concurrency patterns for OCaml applications. Use when Claude needs to: (1) Write concurrent OCaml code with Eio, (2) Handle network operations with cohttp-eio, (3) Manage resource lifecycles with switches, (4) Implement rate limiting or synchronization, (5) Create parallel operations with fibers

• fuzz

  OCaml fuzz testing with Crowbar for protocol implementations. Use when Claude needs to: (1) Write fuzz tests for parsers and encoders, (2) Test roundtrip invariants (parse(encode(x)) = x), (3) Verify boundary conditions and error handling, (4) Test state machines and transitions, (5) Organize fuzz t

• jsont

  JSON type-safe encoding and decoding using the OCaml jsont library. Use when Claude needs to: define typed JSON codecs for OCaml record types, parse JSON strings to OCaml values, or serialize OCaml values to JSON, or work with nested JSON structures

• logs

  OCaml Logs library patterns for structured logging. Use when Claude needs to: (1) Add logging to OCaml modules, (2) Create per-module log sources, (3) Use appropriate log levels, (4) Add structured tags to log messages

• memtrace

  OCaml memtrace profiling for allocation hotspot analysis. Use when Claude needs to: (1) Add memtrace instrumentation to OCaml executables, (2) Run targeted benchmarks with tracing enabled, (3) Identify allocation hotspots from trace output, (4) Optimize code to reduce boxing and allocations, (5) Val

• npm-publishing

  Publishing OCaml to npm via js_of_ocaml and wasm_of_ocaml. Use when discussing browser targets, JavaScript compilation, WASM output, npm packages, or the two-branch workflow.

• ocaml-docs

  Fixing odoc documentation warnings and errors. Use when running dune build @doc, resolving reference syntax issues, cross-package references, ambiguous references, hidden fields, or @raise tags in OCaml documentation.

• ocaml

  OCaml development guidance for building robust, type-safe applications. Use when Claude needs to: (1) Write OCaml code following modern best practices, (2) Design module interfaces (.mli files), (3) Handle errors with result types, (4) Work with dune build system, (5) Use common OCaml libraries (eio

• oxcaml

  Working with the OxCaml extensions to OCaml. Use when the oxcaml compiler is available and you need high-performance, unboxing, stack allocation, data-race-free parallelism

• progress

  Terminal progress bars and spinners using the OCaml progress library. Use when Claude needs to: (1) Add progress bars to long-running CLI operations, (2) Show download/upload progress with bytes and speed, (3) Create multi-line progress displays, (4) Integrate progress reporting with Eio concurrency

• project-setup

  Standards for OCaml project metadata files. Use when initializing a new OCaml library/module, preparing for opam release, setting up CI, discussing project structure, or ensuring proper .mli/.ocamlformat files exist.

• result

  OCaml Result type patterns using OCaml 5.x stdlib. Use when Claude needs to: (1) Handle errors with Result types, (2) Chain Result operations with let*, (3) Extract values from Ok/Error, (4) Refactor code using local let* bindings to use Result.Syntax

• review-ocaml

  Two-phase review of an OCaml project. Use when the user asks to review an OCaml codebase, audit its module interfaces, restructure or redocument .mli files, or hunt for redundancy, dead code and optimisation opportunities across implementations. Phase one reads only dune and .mli files to judge the

• rfc-integration

  Working with IETF RFCs in OCaml projects. Use when mentioning RFC numbers, implementing internet standards, adding specification documentation, or discussing protocol compliance.

• security

  Security hardening for OCaml libraries through systematic vulnerability research. Use when Claude needs to: (1) Research CVEs in similar implementations (C, Rust, Go, Python) and add regression tests, (2) Add fuzz tests for parsers and encoders, (3) Audit integer handling and buffer operations, (4)

• testing

  Testing strategies for OCaml libraries. Use when discussing tests, alcotest, eio mocks, test structure, or test-driven development in OCaml projects.

• tutorials

  Creating OCaml library tutorials using .mld documentation format with MDX executable examples. Use when discussing tutorials, documentation, .mld files, MDX, or interactive documentation.
