What is dsh-observe?

OpenTelemetry and Langfuse observability exporter for DeepSeek Harness.

Turn session events into OTLP traces and Langfuse observations — sanitized, buffered, off by default.

The same run, animated.

Compatibility

| Surface | Status | |---|---| | Harness | DeepSeek Harness dsh-v0.2.1-alpha.1 (adapted 2026-10-04): session format V4 represents a tool result as a first-class role: 'tool' message carrying top-level toolCallId + content + optional isError — the V3 tool-result content block is gone from the host's ContentBlockMap, and this plugin reads only the V4 shape (a pre-upgrade V3 log still projects through a read-only compatibility path). Session format V3's other traits carry over: the assistant stream is embedded in assistant/message / assistant/attempt, and the system prompt is surface node 0 (system/message); the plugin consumes only the live event stream and never reads session log files. The peer range >=0.1.2-rc.1 <0.2.0 \|\| >=0.1.5-alpha.1 <0.2.0 \|\| >=0.1.6-0 <0.2.0 \|\| >=0.1.7-0 <0.2.0 keeps every published line installable (full local gate chain; the compat workflow covers the profile install smoke). | | Node | ^22.19.0 \|\| >=24.0.0 | | Backends | OpenTelemetry OTLP/HTTP (traces + metrics, JSON encoding) and Langfuse (LLM observability) — either or both | | Model | Model-agnostic: it exports the session/event stream; no model calls are made |

What you get

dsh-observe turns the harness's session/event stream into standard observability protocols:

• Spans — turn, step, tool-call (duration, status, retry derivation), and LLM generation spans, linked into per-turn traces with deterministic ids.
• Metrics — per-provider/model token counters, USD cost counters (configurable pricing table), and the optional context-pressure gauge from ctx.tokenMeter.
• Sanitized capture — prompt and completion bodies are redacted (structural key names + built-in secret patterns + your patterns) and truncated before anything is queued or sent.
• Reliability — async batching (size- and timer-triggered), a bounded durable offline buffer (storage-domain) with oldest-first eviction, and deterministic exponential-backoff retries; undeliverable batches survive restarts.
• Runtime kill switch — the optional Typert remote (observe/status, observe/setEnabled) lets a settings page stop and resume exporting without unmounting.
• Off by default — enabled: true plus at least one backend is an explicit opt-in; nothing is captured or exported otherwise.

Quick start

dsh plugin --profile web add github:PerryLink/dsh-observe

# 1. install the bundle into your profile
dsh plugin --profile web add github:PerryLink/dsh-observe

# or from npm (published releases)
dsh plugin --profile web add dsh-observe

# 2. configure a backend in your profile patch (cordis.yml) and restart
dsh --profile web

Minimal OTLP configuration (the row ships commented out in cordis.patch.yml):

- insert:
    - id: dsh-observe
      name: dsh-observe
      config:
        enabled: true
        otlp:
          endpoint: http://localhost:4318

Then verify the row mounts:

dsh --profile web --dump-config | grep -A2 'id: dsh-observe'

Install & uninstall

• git channel (latest main): dsh plugin --profile web add github:PerryLink/dsh-observe — the prepare script builds with production dependencies only.
• npm channel (published releases): dsh plugin --profile web add dsh-observe.
• tarball channel: pnpm pack in this repo, then dsh plugin --profile web add ./dsh-observe-<version>.tgz.
• uninstall: dsh plugin --profile web remove dsh-observe (or remove the row from the profile patch).

If pnpm reports ERR_PNPM_IGNORED_BUILDS for this package (esbuild's harmless platform-binary validation), add allowBuilds: { esbuild: true } to your pnpm-workspace.yaml — the dsh CLI prints the exact snippet.

Configuration

All tunables are Schemastery Config fields (changeable from cordis.yml). An id-targeted override replaces the whole row — restate every key you need. cordis.patch.yml documents each key inline.

Tools & surfaces

This plugin registers no model tools — it is a background exporter. Its surfaces:

• Consumes session/event (span/metric collection), session/flush (best-effort export kick — the durability checkpoint never waits on a remote backend), and session/disposed.
• Optional remote service observe — observe/status returns the kill-switch state, configured backends, queue depths, and buffer occupancy; observe/setEnabled stops and resumes exporting at runtime.

Permissions & data

• Permissions: network:outbound to the endpoints you configure, session:read for the event stream, storage:write for the offline buffer; no native code, no filesystem access.
• Data: everything sent is derived from the session log and sanitized (redaction + truncation) before it is queued, buffered, or transmitted. The offline buffer stores only sanitized records, re-validated when read back.
• Credentials: Langfuse public/secret keys travel only to the configured Langfuse endpoint; OTLP headers only to the configured OTLP endpoint. The plugin stores no credentials itself — keep them in credential references or environment-injected values.

Security boundaries

• Off by default — nothing is captured or exported unless you opt in explicitly.
• Sanitize before send — structural key redaction, built-in secret patterns (API keys, GitHub tokens, AWS keys, bearer credentials, private keys), your patterns, and character budgets all apply before any record leaves memory.
• Durable boundary re-validation — records read back from storage are checked again before a sink can see them.
• Failure loud, failure contained — export failures warn, count, retry, and finally spool; a failing session handler is caught and logged so observability can never break the harness hot path.
• Model-visible ⟺ logged — prompt/completion exports project only the session surface (whose node 0 is the system prompt) and the logged header (call config and tools); the exporter invents no content.

Known limitations

• npm 0.1.7-rc.2 — the plugin is developed and tested against @deepseek-ai/[email protected] (devDeps and CI's primary ruler); the peer range >=0.1.2-rc.1 <0.2.0 || >=0.1.5-alpha.1 <0.2.0 || >=0.1.6-0 <0.2.0 || >=0.1.7-0 <0.2.0 keeps every published line installable, and the second ruler (typecheck:ci) plus the compat workflow cover the older baselines.
• Audit events are not persisted — the exporter's own observe/* records are audit-only: on the current host line the session append gate admits surface events, so no observe/* event is written to the session log, and the plugin does not fake one with an unmarked append (that would make sessions unreadable). Treat /observe status output and the OTLP/Langfuse backends as the audit surface.
• Metrics bypass the retry/spool path — OTLP metrics are aggregated cumulatively, so a lost flush self-heals on the next one (by design, not a bug).
• No sampling — every enabled span family is exported; set capture.* switches and batch.maxBufferRecords for high-volume sessions.
