deepseek-harness-cli 0.3.0

Installed the Node harness (@deepseek-ai/dsh) and things feel off?
Try first: pip install deepseek-harness-cli. 有奇效.

pip install -U deepseek-harness-cli
export DEEPSEEK_API_KEY=sk-...
dsh doctor --node

Five witness probes for the official Node runtime. Each surfaces something
the Node stack does not — with the reason it happens and what to do.

P1-reasoner-skip · thinking-mode history looks incomplete

Why. deepseek-reasoner sometimes skips its reasoning stream on prompts
it deems trivial. It's a model decision, not a wire bug. 200-trial overnight
sampling: bare short prompt → 60–100% silent; same tool with a "reason
step by step" hint → 0% silent, every time. temp doesn't matter;
prompt shape does.

Fix. The probe runs an A/B (bare vs. +CoT hint, N=5 each) and reports
the skip-rate delta. If Δ is large, your prompt is telling the model
"don't bother thinking" — add a hint, or accept reasoning-less turns as a
distinct state.

P2-bom · dsh plugin add crashes on JSON.parse

Why. rc.6 dsh-app-boot/lib/index.js:453 and :548 call JSON.parse
directly on file bytes. A single UTF-8 BOM at file start crashes the whole
plugin add. stripBOM never appears in the compiled artifact.

Fix. Offline scan of your plugin manifest roots (~/.dsh and
friends). Re-save flagged files as UTF-8 without BOM. Upstream:
#2798.

P3-serve · dsh web page hangs on "Select a workspace"

Why. The frontend loads (HTML+JS come back 200), then every data-layer
request under a non-loopback Origin gets 403. No console error. The fence
is doing its job correctly — but with no user-visible failure mode.

Fix. The probe sends the natural request vs. an evil-Origin request
against your running dsh web and reports the fence outcome. If you're
hitting the server from a hostname that isn't 127.0.0.1 / localhost / [::1],
switch. Upstream:
#2573.

P4-spill · harness dies with exit 1 mid-turn

Why. dsh-subprocess-local/src/spawn.ts (spillAll()) calls
openSync and writeSync on the spill file with no try/catch. Any IO
failure — EACCES on a hardened tmp dir, ENOSPC on a full disk, EPERM after
a container restart — escapes the stream data callback and kills the
whole harness. Sibling discardSpill() is guarded; this one isn't. The
asymmetry is the tell.

Fix. Offline writability probe against every tmp candidate dsh might
pick ($TMPDIR, $TEMP, $TMP, /tmp, tempfile.gettempdir()). If any
FAIL, either fix perms or point TMPDIR at a writable dir before starting
dsh.

P5-seqgap · session won't load, or loads with silently fewer events

Why. Two dsh processes on the same workspace → both attach with
state.owner === undefined (the coordinator's owner check is
in-process, not cross-process) → both append to the same session log →
duplicate seq. link()+unlink() prevents overwrites of published
artifacts; it does not prevent this. grep -rE 'flock|O_EXCL|lockf' packages/session/
returns 0. In-process invariants are being treated as system invariants.

The scanner has two failure modes:

  • Silent truncation. Gap without a subsequent turn/end → issue is
    stashed, events truncate at the gap, no error surfaces. User sees a
    session that just quietly lost a turn.
  • Terminal corrupt. Any subsequent turn/end promotes the issue to a
    throw: corrupt session log: seq gap in committed region at line N.
    Session is permanently unloadable.

Fix. Offline scan of user session dirs. Reports both modes. Full
findings + suggested upstream fix (flock(LOCK_EX|LOCK_NB) on log fd) in
docs/upstream/DRAFT-2571-concurrent-writers.md.
Upstream:
#2571.

Also in this release

  • @deepseek-harness/dsh-doctor-plugin — Node-side shim
    (packages/dsh-doctor-plugin).
    A meta-plugin: since the Node runtime advertises "everything is a plugin",
    the doctor is one. bin/dsh-doctor.mjs spawns python -m deepseek_harness_cli doctor --node.
  • First-screen mermaid map in the README: failure mode → symptom →
    doctor verdict. Three columns, five rows. Find your symptom in the middle,
    read across.
  • DEVLOG (docs/DEVLOG.md)
    now records the reasoning trail behind every probe — including two
    reversals (#2802 static-hole after end-to-end validation; P1 from
    "wire silence" to "reasoner skip" after 200-trial sampling).

Breaking change (dev-only)

Probe id renamed: P1-reasoner-wire → P1-reasoner-skip. No stable API
was ever documented under the old id, but if you scripted around it,
update the string.

Not the same tool as

@simon-world/dsh-toolkit
doctor (Node-side, checks Node version / koffi pin / ports / ASCII paths
/ sandbox) — complementary. Theirs: "will it install and start". Ours:
"what will silently bite you after it does".

Initial release — protocol-aware adapters for DeepSeek V4-Pro / V4-Flash

What ships in this release

A single protocol contract, distributed in four wrapper formats:

Form Distribution Status
Python library pip install deepseek-harness ✅ live on PyPI
Command-line tool pip install deepseek-harness-cli ✅ live on PyPI
MCP server npx -y @deepseek-harness/mcp ✅ live on npm
Anthropic Skill drop packages/skill/ into ~/.claude/skills/ ✅ available via git clone

Backed by

Quick verification

pip install deepseek-harness deepseek-harness-cli
export DEEPSEEK_API_KEY=sk-...
dsh doctor
# Expected: green status table; live call cost ~ $0.000002
DEEPSEEK_API_KEY=sk-... npx -y @deepseek-harness/mcp
# Expected: [deepseek-harness-mcp] ready · 4 tools · v0.2.0

Acid test (proves the harness performs a non-trivial transformation)

git clone https://github.com/HenryZ838978/deepseek-harness
cd deepseek-harness
python reports/probes/probe_2_reasoning_lifecycle.py --n 3
# Expected: 3/3 phase-B BadRequestError with the verbatim 400 message
#   "The reasoning_content in the thinking mode must be passed back to the API."
