Honcho Memory for Hermes

Honcho provides AI-native cross-session user modeling. It learns who the user is across conversations and gives every Hermes profile its own peer identity while sharing a unified view of the user.

When to Use

• Setting up Honcho (cloud or self-hosted)
• Troubleshooting memory not working / peers not syncing
• Creating multi-profile setups where each agent has its own Honcho peer
• Tuning observation, recall, dialectic depth, or write frequency settings
• Understanding what the 5 Honcho tools do and when to use them
• Configuring context budgets and session summary injection

Setup

Cloud (app.honcho.dev)

hermes memory setup honcho
# select "cloud", paste API key from https://app.honcho.dev

Self-hosted

hermes memory setup honcho
# select "local", enter base URL (e.g. http://localhost:8000)

See: https://docs.honcho.dev/v3/guides/integrations/hermes#running-honcho-locally-with-hermes

Verify

hermes honcho status    # shows resolved config, connection test, peer info

Architecture

Base Context Injection

When Honcho injects context into the system prompt (in hybrid or context recall modes), it assembles the base context block in this order:

1. Session summary -- a short digest of the current session so far (placed first so the model has immediate conversational continuity)
2. User representation -- Honcho's accumulated model of the user (preferences, facts, patterns)
3. AI peer card -- the identity card for this Hermes profile's AI peer

The session summary is generated automatically by Honcho at the start of each turn (when a prior session exists). It gives the model a warm start without replaying full history.

Cold / Warm Prompt Selection

Honcho automatically selects between two prompt strategies:

Condition	Strategy	What happens
No prior session or empty representation	Cold start	Lightweight intro prompt; skips summary injection; encourages the model to learn about the user
Existing representation and/or session history	Warm start	Full base context injection (summary → representation → card); richer system prompt

You do not need to configure this -- it is automatic based on session state.

Peers

Honcho models conversations as interactions between peers. Hermes creates two peers per session:

• User peer (peerName): represents the human. Honcho builds a user representation from observed messages.
• AI peer (aiPeer): represents this Hermes instance. Each profile gets its own AI peer so agents develop independent views.

Observation

Each peer has two observation toggles that control what Honcho learns from:

Toggle	What it does
observeMe	Peer's own messages are observed (builds self-representation)
observeOthers	Other peers' messages are observed (builds cross-peer understanding)

Default: all four toggles on (full bidirectional observation).

Configure per-peer in honcho.json:

{
  "observation": {
    "user": { "observeMe": true, "observeOthers": true },
    "ai":   { "observeMe": true, "observeOthers": true }
  }
}

Or use the shorthand presets:

Preset	User	AI	Use case
"directional" (default)	me:on, others:on	me:on, others:on	Multi-agent, full memory
"unified"	me:on, others:off	me:off, others:on	Single agent, user-only modeling

Settings changed in the Honcho dashboard are synced back on session init -- server-side config wins over local defaults.

Sessions

Honcho sessions scope where messages and observations land. Strategy options:

Strategy	Behavior
per-directory (default)	One session per working directory
per-repo	One session per git repository root
per-session	New Honcho session each Hermes run
global	Single session across all directories

Manual override: hermes honcho map my-project-name

Recall Modes

How the agent accesses Honcho memory:

Mode	Auto-inject context?	Tools available?	Use case
hybrid (default)	Yes	Yes	Agent decides when to use tools vs auto context
context	Yes	No (hidden)	Minimal token cost, no tool calls
tools	No	Yes	Agent controls all memory access explicitly

Three Orthogonal Knobs

Honcho's dialectic behavior is controlled by three independent dimensions. Each can be tuned without affecting the others:

Cadence (when)

Controls how often dialectic and context calls happen.

Key	Default	Description
contextCadence	1	Min turns between context API calls
dialecticCadence	2	Min turns between dialectic API calls. Recommended 1–5
injectionFrequency	every-turn	every-turn or first-turn for base context injection

Higher cadence values fire the dialectic LLM less often. dialecticCadence: 2 means the engine fires every other turn. Setting it to 1 fires every turn.

Depth (how many)

Controls how many rounds of dialectic reasoning Honcho performs per query.

Key	Default	Range	Description
dialecticDepth	1	1-3	Number of dialectic reasoning rounds per query
dialecticDepthLevels	--	array	Optional per-depth-round level overrides (see below)

dialecticDepth: 2 means Honcho runs two rounds of dialectic synthesis. The first round produces an initial answer; the second refines it.

dialecticDepthLevels lets you set the reasoning level for each round independently:

{
  "dialecticDepth": 3,
  "dialecticDepthLevels": ["low", "medium", "high"]
}

If dialecticDepthLevels is omitted, rounds use proportional levels derived from dialecticReasoningLevel (the base):

Depth	Pass levels
1	[base]
2	[minimal, base]
3	[minimal, base, low]

This keeps earlier passes cheap while using full depth on the final synthesis.

Depth at session start. The session-start prewarm runs the full configured dialecticDepth in the background before turn 1. A single-pass prewarm on a cold peer often returns thin output — multi-pass depth runs the audit/reconcile cycle before the user ever speaks. Turn 1 consumes the prewarm result directly; if prewarm hasn't landed in time, turn 1 falls back to a synchronous call with a bounded timeout.

Level (how hard)

Controls the intensity of each dialectic reasoning round.

Key	Default	Description
dialecticReasoningLevel	low	minimal, low, medium, high, max
dialecticDynamic	true	When true, the model can pass reasoning_level to honcho_reasoning to override the default per-call. false = always use dialecticReasoningLevel, model overrides ignored

Higher levels produce richer synthesis but cost more tokens on Honcho's backend.

Multi-Profile Setup

Each Hermes profile gets its own Honcho AI peer while sharing the same workspace (user context). This means:

• All profiles see the same user representation
• Each profile builds its own AI identity and observations
• Conclusions written by one profile are visible to others via the shared workspace

Create a profile with Honcho peer

hermes profile create coder --clone
# creates host block hermes.coder, AI peer "coder", inherits config from default

What --clone does for Honcho:

1. Creates a hermes.coder host block in honcho.json
2. Sets aiPeer: "coder" (the profile name)
3. Inherits workspace, peerName, writeFrequency, recallMode, etc. from default
4. Eagerly creates the peer in Honcho so it exists before first message

Backfill existing profiles

hermes honcho sync    # creates host blocks for all profiles that don't have one yet

Per-profile config

Override any setting in the host block:

{
  "hosts": {
    "hermes.coder": {
      "aiPeer": "coder",
      "recallMode": "tools",
      "dialecticDepth": 2,
      "observation": {
        "user": { "observeMe": true, "observeOthers": false },
        "ai": { "observeMe": true, "observeOthers": true }
      }
    }
  }
}

Tools

The agent has 5 bidirectional Honcho tools (hidden in context recall mode):

Tool	LLM call?	Cost	Use when
honcho_profile	No	minimal	Quick factual snapshot at conversation start or for fast name/role/pref lookups
honcho_search	No	low	Fetch specific past facts to reason over yourself — raw excerpts, no synthesis
honcho_context	No	low	Full session context snapshot: summary, representation, card, recent messages
honcho_reasoning	Yes	medium–high	Natural language question synthesized by Honcho's dialectic engine
honcho_conclude	No	minimal	Write or delete a persistent fact; pass peer: "ai" for AI self-knowledge

honcho_profile

Read or update a peer card — curated key facts (name, role, preferences, communication style). Pass card: [...] to update; omit to read. No LLM call.

honcho_search

Semantic search over stored context for a specific peer. Returns raw excerpts ranked by relevance, no synthesis. Default 800 tokens, max 2000. Good when you need specific past facts to reason over yourself rather than a synthesized answer.

honcho_context

Full session context snapshot from Honcho — session summary, peer representation, peer card, and recent messages. No LLM call. Use when you want to see everything Honcho knows about the current session and peer in one shot.

honcho_reasoning

Natural language question answered by Honcho's dialectic reasoning engine (LLM call on Honcho's backend). Higher cost, higher quality. Pass reasoning_level to control depth: minimal (fast/cheap) → low → medium → high → max (thorough). Omit to use the configured default (low). Use for synthesized understanding of the user's patterns, goals, or current state.

honcho_conclude

Write or delete a persistent conclusion about a peer. Pass conclusion: "..." to create. Pass delete_id: "..." to remove a conclusion (for PII removal — Honcho self-heals incorrect conclusions over time, so deletion is only needed for PII). You MUST pass exactly one of the two.

Bidirectional peer targeting

All 5 tools accept an optional peer parameter:

• peer: "user" (default) — operates on the user peer
• peer: "ai" — operates on this profile's AI peer
• peer: "<explicit-id>" — any peer ID in the workspace

Examples:

honcho_profile                        # read user's card
honcho_profile peer="ai"              # read AI peer's card
honcho_reasoning query="What does this user care about most?"
honcho_reasoning query="What are my interaction patterns?" peer="ai" reasoning_level="medium"
honcho_conclude conclusion="Prefers terse answers"
honcho_conclude conclusion="I tend to over-explain code" peer="ai"
honcho_conclude delete_id="abc123"    # PII removal

Agent Usage Patterns

Guidelines for Hermes when Honcho memory is active.

On conversation start

1. honcho_profile                  → fast warmup, no LLM cost
2. If context looks thin → honcho_context  (full snapshot, still no LLM)
3. If deep synthesis needed → honcho_reasoning  (LLM call, use sparingly)

Do NOT call honcho_reasoning on every turn. Auto-injection already handles ongoing context refresh. Use the reasoning tool only when you genuinely need synthesized insight the base context doesn't provide.

When the user shares something to remember

honcho_conclude conclusion="<specific, actionable fact>"

Good conclusions: "Prefers code examples over prose explanations", "Working on a Rust async project through April 2026" Bad conclusions: "User said something about Rust" (too vague), "User seems technical" (already in representation)

When the user asks about past context / you need to recall specifics

honcho_search query="<topic>"       → fast, no LLM, good for specific facts
honcho_context                       → full snapshot with summary + messages
honcho_reasoning query="<question>"  → synthesized answer, use when search isn't enough

When to use peer: "ai"

Use AI peer targeting to build and query the agent's own self-knowledge:

• honcho_conclude conclusion="I tend to be verbose when explaining architecture" peer="ai" — self-correction
• honcho_reasoning query="How do I typically handle ambiguous requests?" peer="ai" — self-audit
• honcho_profile peer="ai" — review own identity card

When NOT to call tools

In hybrid and context modes, base context (user representation + card + session summary) is auto-injected before every turn. Do not re-fetch what was already injected. Call tools only when:

• You need something the injected context doesn't have
• The user explicitly asks you to recall or check memory
• You're writing a conclusion about something new

Cadence awareness

honcho_reasoning on the tool side shares the same cost as auto-injection dialectic. After an explicit tool call, the auto-injection cadence resets — avoiding double-charging the same turn.

Config Reference

Config file: $HERMES_HOME/honcho.json (profile-local) or ~/.honcho/config.json (global).

Key settings

Key	Default	Description
apiKey	--	API key (get one)
baseUrl	--	Base URL for self-hosted Honcho
peerName	--	User peer identity
aiPeer	host key	AI peer identity
workspace	host key	Shared workspace ID
recallMode	hybrid	hybrid, context, or tools
observation	all on	Per-peer observeMe/observeOthers booleans
writeFrequency	async	async, turn, session, or integer N
sessionStrategy	per-directory	per-directory, per-repo, per-session, global
messageMaxChars	25000	Max chars per message (chunked if exceeded)

Dialectic settings

Key	Default	Description
dialecticReasoningLevel	low	minimal, low, medium, high, max
dialecticDynamic	true	Auto-bump reasoning by query complexity. false = fixed level
dialecticDepth	1	Number of dialectic rounds per query (1-3)
dialecticDepthLevels	--	Optional array of per-round levels, e.g. ["low", "high"]
dialecticMaxInputChars	10000	Max chars for dialectic query input

Context budget and injection

Key	Default	Description
contextTokens	uncapped	Max tokens for the combined base context injection (summary + representation + card). Opt-in cap — omit to leave uncapped, set to an integer to bound injection size.
injectionFrequency	every-turn	every-turn or first-turn
contextCadence	1	Min turns between context API calls
dialecticCadence	2	Min turns between dialectic LLM calls (recommended 1–5)

The contextTokens budget is enforced at injection time. If the session summary + representation + card exceed the budget, Honcho trims the summary first, then the representation, preserving the card. This prevents context blowup in long sessions.

Memory-context sanitization

Honcho sanitizes the memory-context block before injection to prevent prompt injection and malformed content:

• Strips XML/HTML tags from user-authored conclusions
• Normalizes whitespace and control characters
• Truncates individual conclusions that exceed messageMaxChars
• Escapes delimiter sequences that could break the system prompt structure

This fix addresses edge cases where raw user conclusions containing markup or special characters could corrupt the injected context block.

Troubleshooting

"Honcho not configured"

Run hermes honcho setup. Ensure memory.provider: honcho is in ~/.hermes/config.yaml.

Memory not persisting across sessions

Check hermes honcho status -- verify saveMessages: true and writeFrequency isn't session (which only writes on exit).

Profile not getting its own peer

Use --clone when creating: hermes profile create <name> --clone. For existing profiles: hermes honcho sync.

Observation changes in dashboard not reflected

Observation config is synced from the server on each session init. Start a new session after changing settings in the Honcho UI.

Messages truncated

Messages over messageMaxChars (default 25k) are automatically chunked with [continued] markers. If you're hitting this often, check if tool results or skill content is inflating message size.

Context injection too large

If you see warnings about context budget exceeded, lower contextTokens or reduce dialecticDepth. The session summary is trimmed first when the budget is tight.

Session summary missing

Session summary requires at least one prior turn in the current Honcho session. On cold start (new session, no history), the summary is omitted and Honcho uses the cold-start prompt strategy instead.
