writeonce/.dev

.dev — developer-local links into this project's AI-tooling state

Symlinks to the state that AI tooling reads and writes for this repo only — no global/all-projects state is linked here. Same convention as log-watcher/.dev: user-specific paths, gitignored (only this README is committed). Each developer recreates the links for their own machine (commands below).

Link	Points at	What a developer uses it for
claude-project/	~/.claude/projects/<this-repo, slashes→dashes>	Claude Code's per-project state: session transcripts (*.jsonl) and memory/ (the persistent memory index + facts). Grep a past session, read/curate what Claude remembers about this repo.
skills/<plugin>/<skill>.md	Each installed plugin's skills/*/SKILL.md (~/.claude/plugins/cache/…, version-pinned) plus ~/.claude/skills/* under skills/user/	Read the exact instructions a skill injects (caveman, context-mode, superpowers, …) without digging through the plugin cache. Links break when a plugin updates to a new version — rerun the recreate loop below.

reference/ — v1 archive, smoke files, study-tree symlinks

reference/ (moved here from the repo root, then untracked entirely, 2026-08-08) is developer-local, gitignored — disk-only on each machine; the v1 history remains reachable in git at the pre-move reference/ path. It holds:

• reference/crates/ — the v1 writeonce blog (13 wo-* crates, nested Cargo workspace, excluded from the root workspace). Port source for the dependency-removal plans; do not delete without checking docs/runtime/database/07-wo-seg-migration.md.
• reference/rest/ — .rest HTTP smoke files for the running runtime.
• reference/writeonce-api/, reference/writeonce-app/ — earlier cuts, archived.
• Gitignored, user-specific symlinks to study trees: linux, go, postgresql, mcp-python-sdk, colibri, llama-cpp, llvm-project (recreate per machine; see .gitignore for the ln -s lines).

Study-tree notes:

Link	Points at	Why it's a reference
reference/llvm-project/	~/projects/llvm-project (shallow clone)	Compiler-architecture study for the OCaml woc compiler: pass pipelines (llvm/lib/Passes/), IR design (llvm/docs/LangRef.md), Clang's lexer/parser/sema layering (clang/lib/{Lex,Parse,Sema}/), diagnostics machinery (clang/include/clang/Basic/Diagnostic*.td). Study-only — writeonce does NOT link against LLVM (zero-dep doctrine; woc emits .wob bytecode, no LLVM backend).
reference/dotnet-runtime/	~/projects/dotnet-runtime (shallow + sparse: only src/libraries/System.Linq, 15 MB instead of multi-GB)	Query-surface study for story iteration 9b (@table relations + language-integrated query). Read src/libraries/System.Linq/src/System/Linq/ for the operator set and how each is specified (Where.cs, Select.cs, Join.cs, GroupBy.cs, OrderBy.cs), and the *.SpeedOpt.cs files for how LINQ specializes when the source's shape is known. Study-only, and note the deliberate divergence: LINQ-to-Objects is runtime iterator composition over IEnumerable, while writeonce has no function values and forbids reflection — so writeonce takes the operator vocabulary and semantics, not the delegate/expression-tree machinery.

(The former separate references/ directory was merged into reference/ on 2026-08-08 — one home for all study trees.)

Deliberately not linked (global, cross-project state): ~/.claude (all projects' transcripts, credentials), ~/.config/opencode and ~/.local/share/opencode (global config; sessions for every project; auth.json tokens), ~/.cache/llama.cpp (shared model weights), the llama.cpp checkout's llama-server.log (lives with that checkout — tail -f it there when running prototypes/llama-moe-stream/start-local-agents.sh).

Related, already at the repo root: project-level agent definitions go in .opencode/agents/*.md (opencode) and .claude/agents/*.md (Claude Code) — those are committed when they should be shared with the team, unlike these links.

Recreate on a new machine

cd .dev
ln -sfn "$HOME/.claude/projects/$(git rev-parse --show-toplevel | tr / -)" claude-project
git clone --depth 1 https://github.com/llvm/llvm-project.git ~/projects/llvm-project
ln -sfn "$HOME/projects/llvm-project"  reference/llvm-project

# skills/ — one .md link per installed skill (rerun after plugin updates)
jq -r '.plugins | to_entries[] | .value[0].installPath' ~/.claude/plugins/installed_plugins.json | while read -r p; do
  plug=$(basename "$(dirname "$p")")
  for d in "$p"/skills/*/; do
    [ -f "${d}SKILL.md" ] || continue
    mkdir -p "skills/$plug"
    ln -sfn "${d}SKILL.md" "skills/$plug/$(basename "$d").md"
  done
done

  [ -f "${d}SKILL.md" ] || continue
  mkdir -p skills/user
  ln -sfn "${d}SKILL.md" "skills/user/$(basename "$d").md"
done

(claude-project: Claude Code names the directory after the repo's absolute path with / replaced by -, hence the git rev-parse | tr trick.)

Privacy

This link points into private state: full conversation transcripts and Claude's memory for this repo. It is gitignored so none of it can be committed — keep it that way, and don't bulk-feed the directory to tools that upload content.
