dsh-routines

Scheduled agents for DSH — run a prompt on a cron, get the digest where you already are.

dsh-routines is a plugin bundle for DeepSeek Harness. A routine is a named prompt + schedule + delivery stored as a plain YAML file — human-diffable, git-committable. The scheduler launches each due run through the headless runner as its own one-shot session (full session log = full audit, replay-able later by dsh-replay), then delivers a digest: the last assistant message when it is short, otherwise a one-shot summarizer call over the session log.

Flagship demo — nightly test triage

A routine that runs your test suite at 2am, diagnoses the top failure, and leaves a digest in the project — then, with a conversation node installed, that digest lands in WeChat and you reply to approve follow-ups (v0.2; v0.1 delivers to file and chatnode when a node is installed).

# ~/work/projectx/.dsh/routines/nightly-tests.yaml

schedule: "0 2 * * *"        # 5-field cron; also accept "@daily", "every 4h"

prompt: |
  Run the test suite. If anything fails, diagnose the top failure
  and draft a fix on a branch. Summarize in <10 lines.

  - type: chatnode             # optional: any installed conversation node (wechat…)

Install

# 1. Create the profile that hosts the scheduler + CLI (installs this bundle).
#    From the npm registry once published, or straight from this repository:
dsh plugin --profile ops add @dsh-routines/bundle          # npm (when published)
dsh plugin --profile ops add github:Jesse-njx/dsh-routines  # or: straight from GitHub

# 2. Keep it alive so schedules fire (daemon mode; Ctrl-C to stop).
dsh --profile ops

Routine runs boot the headless profile by default, which ships with DSH — no extra setup needed. A routine that needs another profile’s plugin set sets profile: <name>; that profile must be one-shot-capable (include the headless bundle, or install this bundle into it as well — the run overlay disables the nested scheduler either way).

Scheduler host

The scheduler ticks inside whatever profile the bundle is installed into, so you can also add the bundle to your main web profile and routines fire while the web app runs:

dsh plugin --profile web add @dsh-routines/bundle

Keep the process alive for schedules to fire; dsh --profile ops with no inner arguments is the intended daemon form (the CLI stays silent and the scheduler owns process lifetime).

Routine files

Routines live in two watched directories (hot-reload on change; invalid files are reported, never crash the store):

Cron fields support *, step suffixes (*/15), ranges (9-17), lists (0,30), ?, and month/day names. When both day-of-month and day-of-week are restricted, a day matches if either matches (Vixie cron semantics).

Scheduler bookkeeping (paused set, last-run anchors) lives in <cwd>/.dsh/routines/state.json.

CLI

dsh --profile ops routines <command>

Run records are JSON files under <routine.cwd>/.dsh/routines/runs/<runId>.json, with a human-readable <runId>.md digest next to them. run is also the manual trigger for testing a routine before you trust its schedule.

Safety defaults

Scheduled agents run unattended, so each run subprocess is patched to:

• Auto-deny anything that would prompt — the run overlay forces the approval policy to never (sandbox mode stays whatever the profile inherits, normally workspace-write). Denied requests are collected into the run record (denied) and surface in the digest.
• Never schedule nested runs — the run overlay disables the scheduler row inside the run profile.
• Never crash the scheduler — delivery failures, summarizer failures, and spawn failures are recorded on the run record, not thrown.

Missed runs (laptop asleep): at most one catch-up run fires on wake, never a backlog replay.

Delivery

• file (always on): the run record + digest markdown under .dsh/routines/runs/.
• chatnode (optional): digests are sent through a ctx.chatnode service ({ send(input: { text, title? }): Promise<void> }) when one is installed; otherwise the delivery is recorded as not-installed and the run still completes. A future @dsh-cowork/chatnode-wechat exposing that service lights this up automatically.

Architecture

One bundle, three plugins (+ a run driver), all installable as subpaths:

Runs boot dsh --profile <routine.profile> --patch <generated overlay> -- "<prompt>" with the routine’s cwd as the workspace. The overlay disables the stock headless runner, mounts the run driver on the same task service, and forces the unattended approval policy — so the run keeps the full headless experience (fresh persisted session, provider selection) while writing the audit record only dsh-routines knows how to read.

Development

pnpm install
pnpm build      # tsc -> lib/
pnpm test       # node --test (46 tests: cron, scheduler matrix, store, run, cli, e2e)

The e2e test boots a real dsh subprocess against a scripted mock LLM adapter (no network, no credentials) in a throwaway DSH_HOME, so the whole pipeline — store → scheduler → jobs → subprocess → run driver → digest → record — is exercised in CI.

Promo

promo/ holds a self-contained 60-second promo deck for screen recording: slideshow.html (keyboard-advanceable, 1280×720, no external assets) and narration.txt (a timed read-aloud script). Open slideshow.html and press →/space to advance.

Non-goals

Cloud execution (local machine only; the missed-run policy handles an asleep laptop honestly), routine marketplaces, sub-minute schedules.
