dsh-herdr-site

What it does

Herdr is a terminal workspace manager for AI coding agents. It only recognizes
agents found by its built-in detectors (opencode, claude, codex, ...);
dsh/cc-tui is not on that list, so a dsh pane shows up in Herdr as a plain
terminal process — no state, no panel jump, no --wait support.

This plugin reports the dsh agent's state to Herdr over the official
custom-integration protocol (pane report-agent / pane release-agent):

• working while a turn is running
• idle when no driver is active
• blocked when the model is parked on an ask_user_question, waiting for input

dsh itself only reports running/idle, so the blocked state is the main reason
to use this plugin: the moment the model waits on you shows up in Herdr instead
of looking like it's busy. It is derived from the session event stream
(ask_user_question tool/call / tool/result), keyed by callId, so
replayed or out-of-order events stay consistent.

With state reported this way, Herdr's panel jump and --wait also work for dsh
panes. An optional blockMessage can be attached to the blocked report to
show why the agent is waiting.

Demo

Lifecycle recording (captured with asciinema): the
pane shows working while a turn runs, flips to blocked when the model stops
on an ask_user_question, and recovers once the answer is given.

State mapping

How it reports

State reports go through Herdr's custom integration protocol:

"$HERDR_BIN_PATH" pane report-agent "$HERDR_PANE_ID" \
  --source custom:dsh-herdr-site --agent cc-tui --state <working|idle|blocked> \
  [--message …] [--seq N]

pane release-agent is called when the fiber is disposed, so no stale entries
remain. Reports carry a monotonic sequence number and repeated states are
deduplicated. Outside a Herdr pane the plugin is a no-op: nothing is spawned,
nothing is read.

Compatibility

• Herdr: uses the official custom-integration protocol
  (Integrate your own agent), tested
  against herdrdev/herdr v0.8.0. Any
  version that implements pane report-agent / pane release-agent works.
• DSH: works with both the cc-tui and dsh-tui profiles — the plugin
  only hooks the session event bus and is independent of the surface.

Known edges:

1. The dsh-tui profile does not ship the ask_user_question tool, so the
   blocked state never fires there (working/idle reporting is
   unaffected).
2. The agent label reported to Herdr is fixed at cc-tui.

Install

Prerequisites: a working dsh
installation with the dsh-cc-tui/dsh-base profile. The plugin declares the
profile's packages (@deepseek-ai/cordis at ^4, dsh-session,
dsh-agent) as peer dependencies, supplied by the host profile.

dsh plugin --profile cc-tui add github:WuJiaoJue/dsh-herdr-site

The package ships a dsh.bundle.patch manifest, so the installer adds it to
the profile's bundle layer stack automatically, and cordis.patch.yml inserts
the plugin into every surface the profile boots. Repeat for any other profile
you use (e.g. dsh-tui).

Verify:

dsh --profile cc-tui --dump-config | grep -A2 herdr-site

Installing from a local checkout also works:
dsh plugin --profile cc-tui add /path/to/dsh-herdr-site

Configuration

Optional blockMessage, sent with the blocked report:

# in the profile's cordis.patch.yml, or a --patch overlay
- id: herdr-site
  config:
    blockMessage: '模型等待你的回答'

Build & test

npm install            # dev: @types/node
npm run build          # emits lib/
npm test               # behavioral assertions against a stub herdr CLI
npx tsc --noEmit       # type check

Git installs need no build step: lib/ is committed. pnpm blocks prepare
scripts by default, so relying on an install-time build would break installs
out of the box.

test/smoke.mjs runs the compiled plugin through the full lifecycle on a real
cordis context — working/blocked/idle transitions, dedup, seq ordering,
unrelated tool results, release-on-dispose — asserting every emitted CLI
invocation against a stub herdr binary.

Local development notes

Developing against a live profile with a plain file: dependency has two
gotchas (both encountered in practice):

1. A file: dep copies content at install time — re-run pnpm install in the
   profile after every rebuild, or the profile keeps running the stale copy.

2. With the dependency installed as a bundle layer and a manual insert row,
   bare-name activation was silently skipped; pointing the insert row's
   name: at the absolute lib/index.js path is the reliable dev-only wiring:

   - insert:
      - id: herdr-site
        name: '/absolute/path/to/dsh-herdr-site/lib/index.js'
        config: {}

   If you take this route, also remove the package from the profile's
   dsh.profile.bundles list so the two inserts don't conflict.

Neither applies to the standard dsh plugin add flow described under Install,
which resolves the bundled patch's bare package name correctly.

Limitations

• Herdr's automatic process detection still won't recognize a dsh process as
  an agent on its own (that requires a Herdr-bundled detector update). This
  plugin reports state through the custom-integration path, which gives Herdr
  correct working/idle/blocked, panel jump, and wait without a detector.
• The optional --agent-session-id reference is not wired, so Herdr's
  pane/agent APIs don't expose the linked dsh session id. Automatic session
  restore would additionally require Herdr to know how to launch dsh, which is
  out of scope here. State reporting works regardless.
