Skill Fuzzy Match

Make the DSH / slash menu match skills by ordered-subsequence fuzzy match instead of strict startsWith prefix match.

This plugin is published as an npm package: @amazing-fish/dsh-plugin-skill-fuzzy-match (GitHub Packages). The files in this directory mirror the published package (index.mjs + package.json). Prefer installing the package over copying the source.

Problem

In the DSH slash menu, the skill source (dsh-client-ui-skill) matches candidate skills with skill.name.startsWith(query). So typing /xx only surfaces skills whose name starts with xx; skills whose name merely contains xx (e.g. aa-xx-bb) never appear.

This is inconvenient because skill names are kebab-case and often long (coding-web-search, dataworks-sql-runner, openviking-memory, python-code-review-optimize). Users frequently remember only a middle token (web, sql, memory, review) and type /web expecting to see coding-web-search — but it does not appear.

It is also inconsistent with the sibling command source (dsh-client-ui-commands), which already uses an ordered-subsequence fuzzy matcher (fuzzyScore + boundaryBonus, -/_ boundary weighting, prefix-first ranking, case-insensitive). So /xx can fuzzy-match a command aa-xx-bb but cannot fuzzy-match a skill aa-xx-bb — same menu, two behaviors.

What this plugin does

Patches the live /skill source's candidates method in place to use the same fuzzy subsequence matcher as the command source:

• empty query → return all skills (unchanged)
• non-empty query → keep any skill whose name contains query as an ordered subsequence, rank by score, prefix matches first, -/_ boundary matches boosted
• case-insensitive (also fixes /Web not matching coding-web-search)

The original candidates is restored when the plugin is stopped, updated, or unloaded.

Install (npm / GitHub Packages)

Configure the @amazing-fish scope, then install:

# ~/.npmrc
@amazing-fish:registry=https://npm.pkg.github.com
//npm.pkg.github.com/:_authToken=${GITHUB_TOKEN}

pnpm add @amazing-fish/dsh-plugin-skill-fuzzy-match

Then add a plugin row to your DSH profile's cordis.patch.yml:

- insert:
    - id: ui-skill-fuzzy
      name: '@amazing-fish/dsh-plugin-skill-fuzzy-match'

Restart DSH (or reload the profile) to mount it. This is the persistent path — the plugin survives DSH restarts.

Files

This directory mirrors the published npm package:

• index.mjs — the client plugin body (ESM, export default { inject, apply })
• package.json — npm package metadata (publishConfig.registry = https://npm.pkg.github.com)
• README.md — this file

How it works

dsh-client-ui-skill already registered a / source named skill. Re-registering the same (trigger, name) throws, so this plugin monkey-patches the live source object's candidates field instead. It reuses the original catalog fetch (calling the original candidates with an empty query returns the full skill list, since startsWith('') is true for every name) and then filters/ranks locally with fuzzyScore. No duplicate fetch, no new network calls.

It injects inputTriggers (to access the source registry) and timer (to retry briefly if the skill source registers after the plugin loads).

Verify

After mounting, check the browser DevTools console:

window.__skillFuzzyPatched   // true once patched

You should also see [skill-fuzzy] PATCHED skill source candidates .... Then typing /sql, /memory, /web in the slash menu surfaces dataworks-sql-runner, openviking-memory, coding-web-search respectively.

Alternative: dynamic plugin (temporary, per-process)

You can also load it through the DSH dynamic Cordis plugin tooling (cordis_define + cordis_run) by pasting the body of index.mjs into code.client (change export default {...} to return {...}). The patch takes effect immediately in the current process and is undone on stop/unload. Dynamic plugins do not survive a DSH process restart — for persistence, use the npm install path above.

Upstream

For a permanent fix in DSH itself, the skill source should reuse fuzzyScore/boundaryBonus directly in packages/client/ui-skill of deepseek-ai/deepseek-harness. See the upstream discussion: .

Compatibility

Targets the DSH workspace APIs used by 0.1.0-rc.5-era builds. The patched APIs (inputTriggers.live.sources, the /skill source shape) are internal and may change; pin or test against your checkout before deployment.
