@hy-sde-org/dsh-internal-urls

FS-shaped internal URL schemes for DeepSeek Harness: conflict://, issue://, pr://, and agent:// resolved through one resolver registry (ctx.internalUrls) that the read/grep/write tools consult before touching the filesystem. Ported from the @oh-my-pi coding-agent internal-urls system (the port lives in the hy-sde fork) and shipped as a standalone plugin: the registry row installs via cordis.patch.yml, and the routing tools install as agent-scope shadows (@hy-sde-org/dsh-tool-fs-internal-urls / @hy-sde-org/dsh-tool-fs-search-internal-urls). Nothing in the upstream DeepSeek Harness (dsh-v0.1.2-rc.1 and later) needs to change.

URL shapes

• conflict://<N> — a recorded git conflict block (register one by reading the conflicted file; read appends a resolution notice with the ids). conflict://<N>/ours|theirs|base renders one side; conflict://* summarizes every registered block. write({ path: "conflict://<N>", content }) splices the resolution into the backing file (@ours / @theirs / @base / @both line tokens expand; conflict://* bulk-resolves). <path>:conflicts reads a whole-file conflict summary.
• issue:// / pr:// — GitHub-as-filesystem through the gh CLI: issue://owner/repo, issue://123, issue://owner/repo/123, pr://N/diff, pr://N/diff/all, pr://N/diff/<i>, list options (?state=open&limit=30, ?comments=0).
• agent://<id> — one subagent's final assistant output (a child session id with origin === 'subagent'). agent://<parent>/<child> walks the parentSession chain to a nested child output. Outputs are read-only markdown backed by the published @deepseek-ai/dsh-session-query service (ctx.sessionQuery), which is an optional peer: without it every agent:// read reports a corrective "outputs unavailable" error instead of failing registration. The omp ?q= JSON extraction form is not supported — agent outputs are markdown, not jq-able documents — and returns an explicit error.

Install

pnpm install --global @deepseek-ai/dsh

Direct from npm (published)

All three packages are published on the npm registry under the hy-sde-org organization (version 0.1.2-rc.1). Add the service, then mount the routing tools via a preset:

dsh plugin --profile web add @hy-sde-org/dsh-internal-urls \
  @hy-sde-org/dsh-tool-fs-internal-urls \
  @hy-sde-org/dsh-tool-fs-search-internal-urls

Then copy examples/agent-preset/ from the installed package (or this repo) to ~/.dsh/.agent-presets/<id>/ and select it in the Web UI preset picker.

From the git checkout (pre-publish / development)

git clone [email protected]:hy-sde/dsh-plugins.git
cd dsh-plugins
pnpm install
pnpm --filter @hy-sde-org/dsh-internal-urls build

IU_TGZ="$(cd dsh-internal-urls/packages/internal-urls && ppnpm pack --silent --pack-destination /tmp)"
FS_TGZ="$(cd dsh-internal-urls/packages/tool-fs-internal-urls && pnpm pack --silent --pack-destination /tmp)"
SEARCH_TGZ="$(cd dsh-internal-urls/packages/tool-fs-search-internal-urls && pnpm pack --silent --pack-destination /tmp)"
dsh plugin --profile web add "$IU_TGZ" "$FS_TGZ" "$SEARCH_TGZ"

How stock-harness routing works

The official harness ships dsh-tool-fs (read/write/edit) and dsh-tool-fs-search (grep) host-wide, with no seam into ctx.internalUrls (that routing only exists in the hy-sde fork). This plugin therefore mounts agent-scope shadow copies of those two tool suites that behave identically on plain filesystem paths and route internal URLs through the registry when mounted — harness scoped-tools semantics let the agent's own registration shadow the global one, so only sessions using the preset preset get the routing, and stock tool behavior elsewhere is untouched.

Service API

await ctx.plugin(InternalUrls)

const iu = ctx.internalUrls                  // InternalUrlsService
iu.register(handler)                         // one ProtocolHandler per scheme
await iu.resolve('conflict://1', { sessionKey, cwd, signal })
await iu.write('conflict://1', '@theirs', { sessionKey, cwd, signal, sandboxPolicy })
iu.conflicts(sessionKey)                     // per-session ConflictHistory

Handlers are plain objects ({ scheme, immutable, resolve, write?, complete? }) registered per scheme; the shipped conflict://, issue://, pr://, agent:// handlers mount with the plugin and are removed on unmount. The agent:// handler resolves its session-query store lazily at resolve time, so deployments without the optional @deepseek-ai/dsh-session-query peer keep the registry healthy.

Config (the internal-urls row)

No configuration today — the row is inserted bare. Handler state (conflict histories) is keyed by session inside the service; the optional SandboxExecutionPolicy rides the write context opaque from the routing tool.
