dsh-hermes-link

Bidirectional bridge between Hermes Agent and DeepSeek Harness (DSH). Hermes dispatches focused tasks (one-shot or continuable) via JSON-RPC over POST /mcp/collab; DSH spawns sub-agents, returns real measured tokens, and lets you continue any Hermes session as a native DSH session in the sidebar.

Why dsh-hermes-link exists

Hermes is an agent-orch-estrator — it plans the work, picks the skill, loads the knowledge slice. DSH is a coding-runtime — it runs sub-agents, edits files, runs shells, talks to LLMs. Each tool does its job well in isolation; the question was always how to make them one system without dragging each one's concerns into the other.

Earlier we ran this as three separate plugins (hermes-foundation, hermes-oneshot-arbitrate, hermes-dispatch-bridge). That triad is now archived under dsh-hermes with an archive/hermes-legacy-2026-08-22 tag — dsh-hermes-link is the single plugin that replaced them, and this repository is the home of that replacement.

Features

Agent-communication line (Hermes → DSH)

POST /mcp/collab — JSON-RPC 2.0 endpoint Hermes posts to.
- dispatch_task with mode: one-shot | continuable. Continuable children are durable across DSH restarts (SQLite-backed).
- dispatch_followup / dispatch_interrupt / dispatch_list / dispatch_get / get_dispatch.
- dispatch_probe — zero-cost tool-name validation against ctx.tools.view().restrictableNames so Hermes doesn't burn an LLM turn on a typo.
- get_dispatch — read audit.jsonl for the most recent entries.
Bearer auth via HERMES_LINK_TOKEN env (open by default).
H4 amend nonce (v0.2.2+): amend files must be named <ts>-<task_id>-<nonce>.json; nonce returned in dispatch_task metadata.
Consult reply_secret (v0.2.2+): reply files must be named <ticket>-<secret>.json; secret returned in the consult payload.
Persona envelope: SOUL injected (v0.2.2+); include_project_memory: true opts in cwd-scoped MEMORY; encoding rules prevent CJK mojibake; sentinel strings are never paraphrased.
Real measured tokens: ctx.tokenMeter.measure(run.localAgent) populates tokens_used on the dispatched result — no more null in dispatch-result.

User-view line (DSH → Hermes)

Tool	Purpose
`list_hermes_sessions`	enumerate Hermes archives enriched with title/model/cwd from Hermes `state.db`
`import_hermes_session`	convert a Hermes archive to a live DSH session — click-to-resume
`load_hermes_persona`	inject Hermes SOUL.md + config into the current session (v0.2.3: no longer reads MEMORY.md)
`load_hermes_project_memory`	cwd-scoped Hermes MEMORY.md loader (matches only this project's Hermes sessions)
`consult_hermes`	ask Hermes a question (file-based async; reply must carry secret suffix since v0.2.2)
`mirror_session_to_hermes`	opt-in V4 mirror with secret-pattern redaction (v0.2.2; cookies / JWTs / API keys / set-cookie / session_id redacted)
`hermes_inbox` / `hermes_inbox_append`	read / append to the shared conversation record (`~/.dsh/hermes-inbox/session.jsonl`)
`hermes_clear_injected`	audit-only: count turns auto-injected by an older hermes-foundation/dsh-hermes-link version, point at "open a new session"

Auto-loop

Startup auto-sync imports every Hermes session into DSH.
fs-watcher polls Hermes Home/sessions/ and re-syncs on new dumps.
heartbeat (60s), usage (per-task), memory-suggest all run in the background.
amend watcher (H4 nonce-bound) delivers mid-task amendments from Hermes to running continuable children.
Hermes Home auto-detect: HERMES_HOME env → %LOCALAPPDATA%\hermes on Windows → ~/.local/share/hermes on POSIX.

Security boundaries

Risk	Mitigation	Since
Cross-project context pollution (Hermes injects project-A dialogue into DSH's project-B session)	main-session auto-injection disabled; MEMORY.md not broadcast; project-memory only matches cwd	v0.2.1 + v0.2.2 + v0.2.3
Adversary writes `amend/*` to hijack a running sub-agent	nonce-bound filename (`<ts>-<task_id>-<nonce>.json`)	v0.2.2
Adversary writes `consult-reply/*` to impersonate Hermes	secret-bound filename (`<ticket>-<secret>.json`)	v0.2.2
Dispatched sub-agent inherits global MEMORY notes from unrelated projects	foundation = SOUL-only; `include_project_memory: true` is explicit opt-in per dispatch	v0.2.2
Hermes state.db poisoned cwd → `C:\Windows\System32`	`isSafeCwd()` rejects 17 system roots + null byte + >1024 chars	v0.2.3
Mirror filename >200 chars triggers `ENAMETOOLONG` silent failure	sha1(12 hex) tail truncation with preserved uniqueness	v0.2.3
Mirror leaks cookie / set-cookie / session_id	redact regex list expanded to 10+ secret shapes	v0.2.3
Imported sessions resume-unusable (`turn:0` events fail DSH persistence validator)	turn envelope rewritten to start at 1; corrupt artifacts auto-removed and rebuilt	v0.2.4

See docs/security-model.md for the full layered model.

Quickstart

Install from dsh-market (recommended)

# 1. Make sure dsh-market is installed in your profile
dsh plugin --profile web add dshmarket

# 2. Restart dsh web, open Settings → Plugin Market, search "dsh-hermes-link", one-click install

Install from npm directly

dsh plugin --profile web add @Tianbuyu-wwx/dsh-hermes-link

Install from a local checkout (dev loop)

git clone https://github.com/Tianbuyu-wwx/dsh-hermes-link.git
cd dsh-hermes-link
dsh plugin --profile web add ./packages/dsh-hermes-link

Then restart dsh web. Open Hermes-config.yaml (%LOCALAPPDATA%\hermes\config.yaml on Windows) and add:

mcp_servers:
  dsh-bridge:
    url: http://127.0.0.1:3080/mcp/collab

Optionally set HERMES_LINK_TOKEN in your DSH env to require a Bearer header (off by default).

Verify

node scripts/verify-install.mjs

Then in DSH:

/mcp/collab/health → { ok: true, version: "0.2.4", importer_ready: true, persona_ready: true, consult_ready: true, auth: "open|bearer-required", continuable_registry: "on", foundation_slice_chars: 1234, active_dispatchers: 0 }

Configuration

Env var	Default	Purpose
`HERMES_HOME`	auto-detected (`%LOCALAPPDATA%\hermes` on Windows, `~/.local/share/hermes` on POSIX)	Hermes data root
`HERMES_LINK_TOKEN`	unset	When set, every `/mcp/collab*` (except `/health`) requires `Authorization: Bearer <token>`
`HERMES_LINK_TRUST_LEGACY`	unset (`0`)	When set (`1`), legacy `<ticket>.json` consult-reply is accepted alongside the v0.2.2 `<ticket>-<secret>.json`

Security model

docs/security-model.md walks through each layer in detail. TL;DR — every cross-project channel is explicit opt-in; every cross-process channel is authenticated; no null tokens, no unbounded system paths, no unredacted cookie/secret leakage.

Report vulnerabilities privately via GitHub Security Advisories on this repo. See SECURITY.md.

FAQ

Q: Does Hermes need to upgrade anything to talk to dsh-hermes-link v0.2.2+? Yes. The amend nonce + consult reply_secret protocols are breaking changes. See docs/hermes-upgrade-v0.2.2.md and the reference gateway in scripts/hermes-gateway-demo.py.

Q: I imported a Hermes session — it shows in the sidebar but I can't open it. That's the v0.2.4 bug (turn:0 envelope failing DSH persistence validator) — fixed in v0.2.4 by bumping turn/start..turn/end to 1 and auto-rebuilding corrupt artifacts. Update to v0.2.4 (auto-recovery runs on next sync) or dsh plugin update dsh-hermes-link.

Q: My import_hermes_session returns "invalid output" before v0.2.4. Same issue — fixed by declaring firstUserSnippet / model / attach in the tool output schema and normalizing nullable fields. Update to v0.2.4.

Q: What's the difference between consult_hermes and Hermes' own consult? Both end up at Hermes. consult_hermes is a DSH tool that any user can call inside their session; dispatch_task is the agent-comm RPC that Hermes initiates. They share the file-based reply protocol but live on different routes (POST /mcp/collab/consult vs POST /mcp/collab).

Q: Why not just one plugin instead of three (hermes-foundation / -oneshot-arbitrate / -dispatch-bridge)? That's exactly what v0.2.0 did — those three are archived under dsh-hermes with tag archive/hermes-legacy-2026-08-22. Single-plugin form is less bookkeeping and easier to reason about; dsh-hermes-link is that consolidation.
