Verified

@hy-sde-org/dsh-tool-tsfork · v0.2.1-alpha.4 · MIT

tsfork devices (tsfork_status, tsfork_check) over a parked Go-native TypeScript compiler (can1357/TypeScript perf fork, TS 7.1.0-dev): status/version probe and one-shot -b project-graph checks with parsed diagnostics, timing, and a GOMAXPROCS cap.

Install

dsh plugin add @hy-sde-org/dsh-tool-tsfork

Confirm the layer applied with dsh --profile default --dump-config — see the install guide.

@hy-sde-org/dsh-tool-tsfork

Model-facing tsfork devices for DeepSeek Harness: tsfork_status and tsfork_check, driving a parked Go-native TypeScript compiler (the can1357/TypeScript perf fork, perf/checker-speedups-v3, TS 7.1.0-dev) as one-shot -b project-graph checks with parsed diagnostics, wall time, and a GOMAXPROCS cap.

Decision-experiment numbers behind this plugin (2026-10-11, on the fork harness's own 337-project host graph, noEmit):

run stock [email protected] tsfork Go 7.1.0-dev
cold tsc -b tsconfig.host.json 54.25s wall / 91.6s user 7.05s wall / 27.0s user (7.7×)
warm 0.65s 0.56s

Graph listings (--dry) and error output are byte-identical (14/14 planted errors, deterministic). CPU work is 3.4× less — the cache-insensitive floor.

Devices

  • tsfork_status (zero params) — resolved binary, --version probe, build stamp (<binaryDir>/VERSION).
  • tsfork_check — tsc -b <project> (or -p fixture checks via args), returning exitCode, wallMs, errorCount/warningCount, parsed diagnostics (file:line:col TSxxxx), an outputTail, and a reproducible command. dry: true prepends --dry (cheap graph-coverage probe).

The plugin registers a tsfork:tools system-prompt section documenting the buildinfo gotcha and the adoption boundary (below).

Install (fleet flow)

# 1. park a compiler binary (or point `binary` at your own):
#    inside a checkout of the fork's tsc/ dir: go build -o ~/.dsh/tsfork/tsc ./cmd/tsc
#    (the tree ships generated files; no generate step needed)

# 2. wire into the profile (absolute file: path — the anchorPathSpec only
#    rewrites ./ ../ file: link: specs):
cd ~/.dsh/profiles/web
pnpm add file:/Users/hui/Documents/github/dsh-plugins/dsh-tool-tsfork/packages/tool-tsfork

# 3. add '@hy-sde-org/dsh-tool-tsfork' to dsh.profile.bundles in package.json
#    (the package's own cordis.patch.yml mounts row `hy-sde-tsfork`)

Per-deployment config rides the row (binary, defaultProject, defaultCwd, timeoutMs, gomaxprocs, maxOutputBytes) — patch hy-sde-tsfork by id.

Gotchas

  • .tsbuildinfo is compiler-version-tagged — alternating tsfork_check with the repo's stock tsc -b invalidates the other side's incremental caches; runs go cold. The prompt section warns agents.
  • GOMAXPROCS defaults to 4 (row config) to avoid oversubscribing a shared box across concurrent lanes; override per call.
  • Adoption boundary: tsfork does NOT replace the pinned toolchain — oxlint typeAware and the typert generator need the JS API ([email protected]; TS 7's npm package is a launcher shim with no lib/typescript.js). Promotion path (if the trial proves out) is a pnpm override of the gate binary, not this plugin.

Development

pnpm install && pnpm build && pnpm check && pnpm test

Integration tests auto-skip when ~/.dsh/tsfork/tsc is absent.
