README

dsh-skill-curator

Automatic skill curation for DeepSeek Harness (DSH). After every N real conversation turns (default 3), the plugin fires a background subagent that reads a digest of the session and creates or updates SKILL.md files under the user skills directory (~/.dsh/skills/<name>/SKILL.md) — the same self-improvement loop Nous Research's Hermes Agent runs, ported to DSH as a zero-intrusion bundle plugin.

中文说明见 README.zh-CN.md.

How it works

turn ends ──▶ agent/turn-stopping (scoped listener, counted per agent)
    │ 3 turns reached?  (skillNudgeInterval)
    ▼
async fire-and-forget (never blocks the turn close)
    ▼
session digest built ──▶ latest N messages verbatim + older turns compressed
    ▼
spawn subagent (provider: spawn) with digest + review instructions
    │  toolFilter allow = skill-library-* only (whitelist, hermes-style)
    ▼
subagent reviews and writes ~/.dsh/skills/<name>/SKILL.md
    │  frontmatter is stamped author: dsh-skill-curator (ownership marker)
    ▼
summary logged (host journal) + visible in the settings card status panel

Backstage review subagent in the Tasks panel

The review subagent runs as a visible task in the Tasks panel — here you see queued/idle skill review entries; open the panel to watch a curation as it happens.

Manual trigger: /skill-refine [focus] runs a review of the current session immediately.

Install

cd /path/to/dsh-skill-curator
dsh plugin --profile web add ./
# restart dsh, then open: Settings → Plugins tab → "Skill Curator" card

Skip the restart? The plugin only takes effect on next start (standard bundle plugin; no dsh source changes, ever).

Settings (Settings → Plugins tab → "Skill Curator" card)

Settings card (part 1)Settings card (part 2)
Settings card 1/2Settings card 2/2
  • enabled — master switch (default on)
  • skillNudgeInterval — turns between reviews (default 3)
  • notifyMode — off / on / verbose (segmented buttons)
  • reviewProvider / reviewModel — optional review subagent model override (empty = follow the session's current model)
  • reviewBaseUrl / reviewApiKey — optional custom review endpoint (OpenAI-compatible /chat/completions). When reviewBaseUrl + reviewModel are set, the review subagent runs against that endpoint through a dedicated adapter route (provider name = reviewProvider, or skill-curator-review by default). Settings are read live on every request — no restart needed
  • Review history persists to ~/.dsh/skill-curator/reviews.json (last 50 entries) — survives plugin removal/reinstall and restarts
  • Review resilience — two layers for endpoint/model failures (HTTP/network/auth/rate-limit/model missing/timeout): ① if the custom endpoint fails, the review retries once on the session's own model (marked ⚠️已回退主模型 in host log / review log / status panel); ② if the final attempt then dies on an endpoint-class error or a detail-less killed, it retries up to reviewRetryCount times with reviewRetryDelayMs backoff — a model connection blip no longer loses the review. Tool-layer errors are never retried
  • reviewTimeoutMs — review subagent budget (default 15 min)
  • reviewRetryCount — extra retries when the final review attempt dies on endpoint/model-layer failures (connection reset, HTTP errors, timeouts) or a detail-less killed; 0 disables retrying. Tool-layer errors are never retried. Default 1
  • reviewRetryDelayMs — backoff base for retries, n-th retry waits base × n ms (default 5000)
  • digestTail / digestMaxChars — digest shape
  • adoptSkills — comma-separated names of skills the curator may maintain although created elsewhere

Skill library tools (whitelist)

The review subagent can only call these six (they are also usable by any session):

ToolPurpose
skill-library-listlist skills (name, description, owned?)
skill-library-readread one SKILL.md
skill-library-createcreate a class-level umbrella skill (Chinese body, bilingual description)
skill-library-patchtargeted oldString→newString or whole-body replacement (frontmatter preserved)
skill-library-write-filesupport files under references/ templates/ scripts/
skill-library-adopttake ownership of an unowned skill (stamps the author marker)

Ownership guard: only skills stamped author: dsh-skill-curator or listed in adoptSkills can be patched; everything else is refused with an explicit "adopt first" message. Paths are boundary-checked; writes are atomic (tmp + rename).

Requirements

// package.json — machine-readable
"engines": { "node": ">=22" },
"dependencies": {
  "@deepseek-ai/dsh-llm": "^0.1.5-rc.1",
  "@deepseek-ai/dsh-settings": "^0.1.5-rc.1",
  "@deepseek-ai/dsh-subagent": "^0.1.5-rc.1",
  "@deepseek-ai/dsh-tools": "^0.1.5-rc.1",
  "@deepseek-ai/schemastery": "^3.18.2"
},
"dsh": { "engines": { "dsh": ">=0.1.2-alpha.3 <0.2.0 || >=0.1.5-alpha.1 <0.1.6" } }
  • Verified host: @deepseek-ai/dsh 0.1.5-rc.1 (Node v24).
  • Why the disjunction is load-bearing: npm semver only satisfies a prerelease from a range group that itself contains a prerelease with the same [major,minor,patch] tuple, so the plain <0.2.0 group does not cover 0.1.5-rc.1. test/entry.test.mjs pins this with a 10-row decision table, a counter-proof (reverting to the old single range turns red), and a cross-check against the host's real semver.satisfies.
  • No install scripts, no gyp/native deps: the whole tree is plain ESM; test/entry.test.mjs guards this (no install/postinstall/prepare, no optionalDependencies, dependency scope limited to @deepseek-ai/*).

Development

pnpm install                # needs proxy/cache off the default npm cache on some hosts
npm test                    # entry + unit + smoke + client-smoke (all suites)
node test/entry.test.mjs    # entry load, manifest, engines range, key-set parity, dep hygiene
node test/smoke.mjs         # module/tool/whitelist smoke
node test/client-smoke.mjs  # client bundle smoke (real component-tree execution)

docs/EVIDENCE.md records the isolated-instance install/start/E2E run (disposable DSH_HOME, no deployed instance touched); docs/AUDIT.md records the audit rounds.
