dsh-review-skills

Engineering-discipline skill pack for DeepSeek Harness — five battle-tested procedures delivered as a bundled skill provider: code review, simplification, plan-then-execute, test-first, and conflict resolution.

Overview

dsh-review-skills packages the discipline that senior engineers apply by habit into model-visible skills. Once installed, the harness discovers five SKILL.md bundles through the standard ctx.skills registry and can invoke them when a task matches.

The skills

Skill	When to use
code-review	Before merging: review a diff for correctness, test coverage, edge cases, needless complexity, and security. Produces severity-ranked findings.
simplify	After a change lands: find and remove accidental complexity — clearer names, fewer layers, less code that does the same thing.
plan-then-execute	Before implementing anything non-trivial: write a plan, get it accepted, then execute it.
test-first	TDD discipline: red → green → refactor, with honest tests and no fake green.
resolve-conflict	When a merge or rebase hits conflicts: understand both sides, resolve deliberately, verify.

Who is it for?

• Solo developers who want a senior-engineer checklist without hiring one.
• Teams that want consistent review and planning standards across sessions.
• Anyone building on the dsh skill system who wants a reference-quality skill pack to copy.

Compatibility

• Built and verified against @deepseek-ai/dsh@0.1.0-rc.6 / @deepseek-ai/cordis@^4.0.1 / @deepseek-ai/dsh-skill@^0.1.0-rc.6.
• Last verified: 2026-08-14.
• Requires a dsh composition that mounts the ctx.skills service (the dsh-base bundle ships it).
• dsh is in developer preview; the skill frontmatter contract (name / description / whenToUse / invocation flags) may evolve. The included unit tests pin the format this pack targets.

Install / Uninstall

Install into a dsh profile (local checkout):

cd /path/to/deepseek-harness
pnpm dsh plugin --profile web add /path/to/dsh-review-skills

From GitHub (source install — pnpm runs the prepare script, so allow it once):

pnpm dsh plugin --profile web add github:<you>/dsh-review-skills

From npm (once published):

pnpm dsh plugin --profile web add dsh-review-skills

Uninstall:

pnpm dsh plugin --profile web remove dsh-review-skills

Quick start

Install the bundle, restart dsh, then simply ask:

Use the code-review skill on the current diff before we merge.

or mention a skill by name in context:

Plan-then-execute: refactor the auth module, then implement.

The harness resolves the skill through ctx.skills and injects its procedure when the model invokes it.

Configuration

None. The plugin registers its provider with no config; the skills and their routing metadata live in skills/*/SKILL.md frontmatter (name, description, whenToUse, disable-model-invocation, user-invocable).

Permissions & data

• Read-only: the plugin reads its own packaged skills/ directory; it writes nothing and touches no user files.
• No network: all five skills are static Markdown bundled in the package.
• Model-visible content: skill bodies are injected into the model context only when the skill is invoked, per the harness skill catalog policy.

Troubleshooting

Symptom	Cause	Fix
Skills not discoverable	ctx.skills service not mounted in the composition	Verify the profile loads dsh-base (which ships the skill service)
missing YAML frontmatter at boot	A packaged SKILL.md lost its --- block	Rebuild/reinstall; the tests (pnpm test) catch this before publish
Skill does not apply to the conversation	The model decided it was not relevant	Ask explicitly: "use the code-review skill"
Stale skill content	Old lib/ after editing skills/	Rebuild (pnpm run build) and reinstall; skill bodies load lazily from disk

Development

pnpm install
pnpm run build         # tsc → lib/
pnpm run test          # vitest: frontmatter contract + 5 bundled skills present

Structure:

• skills/<name>/SKILL.md — one skill per directory; frontmatter drives routing, body carries the procedure.
• src/skills.ts — frontmatter parser and the bundled provider (lazy body loading).
• src/index.ts — plugin entry registering the provider on ctx.skills.
• tests/ — pins the frontmatter contract and asserts all five bundles are parseable.

Design notes:

• Follow the existing skill-file conventions in the dsh repo (@deepseek-ai/dsh-skill types: SkillCandidate, SkillDefinition, SkillProvider) — this pack mirrors the dsh-skill-badge precedent.
• Keep each skill body focused: when-to-use, procedure steps, pitfalls, verification. A skill that tries to cover everything covers nothing.
