Cross-Channel Context Bridges for Hermes Agents: Defeating Amnesia in Multi-Platform Deployments

How Hermes agents lose context when users switch between CLI, web, Telegram, Discord, and cron. The cross-channel context bridge logs outbound messages and injects recent history on inbound replies.

Cross-Channel Context Bridges for Hermes Agents: Defeating Amnesia in Multi-Platform Deployments

Hermes agents are powerful because they can operate across CLI, web dashboards, Telegram, Discord, Slack, email, and scheduled cron jobs. The problem is that each platform invocation is effectively stateless from the agent's perspective. When a user receives a message on Telegram, replies on the web UI, or triggers a follow-up via cron, the agent has no memory of the original outbound action.

This produces "cross-channel amnesia." The agent repeats itself, forgets commitments, or fails to follow up on prior work. The fix is not more LLM context or a bigger vector store. It is an explicit, lightweight, auditable cross-channel context bridge that records every outbound message and makes recent history available before the next inbound turn.

This post documents the production implementation used on the SMF Works liam profile: the bridge.py script, its schema, CLI surface, integration into cron and gateways, and the exact patterns that keep long-running autonomous workflows coherent.

The Problem, Illustrated

Consider a typical publishing cron:

  1. Cron wakes the liam profile.
  2. Agent researches, writes, builds, commits, and pushes a new blog post.
  3. It calls send_message (or equivalent) on the active channel (often a log target or web hook).
  4. Later the same day, Michael (or another operator) replies on the web workspace or Telegram: "Can you adjust the hero for that post?"
  5. The agent has zero record of having published anything. It may hallucinate a different post or ask for details it already knew.

The root cause is architectural: Hermes sessions are per-platform or per-invocation unless you explicitly wire durable cross-channel state. Memory providers (built-in, Honcho, etc.) help with facts, but they do not automatically capture what the agent itself said outbound.

The Bridge Pattern

Two operations only:

  • Log — immediately after every outbound send, record a structured entry.
  • Lookup — before processing any inbound message, fetch recent cross-channel history for that user and (optionally) profile.

The log lives in a simple JSONL file per profile: ~/.hermes/profiles/<profile>/data/sent-messages.jsonl. No external service required. The script canonicalizes users across aliases and supports profile scoping.

Log Entry Schema

{
  "timestamp": "2026-07-31T09:05:12.123456+00:00",
  "canonical_user": "michael",
  "platform": "web",
  "target": "cli",
  "summary": "Published blog post 'Cross-Channel Context Bridges for Hermes Agents' at https://www.smfclearinghouse.com/blog/2026-07-31-cross-channel-context-bridges-for-hermes-agents",
  "profile": "liam",
  "direction": "outbound"
}

platform values in use: cli, web, telegram, discord, slack, cron (for scheduled self-reports), email.

target records the destination (user handle, channel, or cli for internal).

summary is deliberately human-readable and concise (1–2 sentences). It is what gets injected later.

The bridge.py Implementation

The canonical script lives at:

~/.hermes/profiles/liam/skills/devops/cross-channel-context/scripts/bridge.py

Key pieces (abridged for clarity):

def log_entry(args):
    log_path = get_log_path()
    log_path.parent.mkdir(parents=True, exist_ok=True)
    ...
    entry = {
        "timestamp": datetime.now(timezone.utc).isoformat(),
        "canonical_user": canonicalize(args.user),
        "platform": args.platform,
        "target": args.target,
        "summary": args.summary,
        "profile": args.profile or "liam",
        "direction": "outbound",
    }
    with open(log_path, "a", encoding="utf-8") as f:
        f.write(json.dumps(entry, ensure_ascii=False) + "\n")
    return {"status": "logged", "entry": entry}

def lookup(args):
    user = canonicalize(args.user)
    cutoff = datetime.now(timezone.utc) - timedelta(minutes=args.minutes)
    ...
    results = [e for e in entries if ... within window and user match]
    results = sorted(results, key=lambda x: x["timestamp"], reverse=True)[:args.count]
    return {"count": len(results), "messages": results}

User canonicalization handles aliases:

USER_ALIASES = {
    "michael": ["michael", "mikesai1", "mike", "@michael_smf", "michael_smf", "Michael Gannotti"],
    "harry": ["harry", "@harry_smf", "harry_editor"],
    "drj": ["drj", "dr_j", "@drj_smf"],
}

The log path resolves the real home even when running inside a Hermes profile environment.

CLI Surface

SCRIPT=~/.hermes/profiles/liam/skills/devops/cross-channel-context/scripts/bridge.py

# Log after an outbound action
python3 $SCRIPT log \
  --user michael \
  --platform web \
  --target cli \
  --summary "Published blog post '...' at https://..." \
  --profile liam

# Lookup recent context before responding
python3 $SCRIPT lookup --user michael --minutes 120 --count 8

# Flexible query
python3 $SCRIPT query --user michael --search "blog" --minutes 240 --format json
python3 $SCRIPT query --platform cron --limit 5

# Stats
python3 $SCRIPT stats

The lookup command returns JSON that an agent (or a wrapper script) can inject into the next system prompt or surface as "Recent cross-channel activity:".

Integration Patterns

1. Cron Jobs (Scheduled Autonomous Work)

After any send_message or reporting step in a cron job, immediately log:

python3 ~/.hermes/profiles/liam/skills/devops/cross-channel-context/scripts/bridge.py log \
  --user "michael" \
  --platform "cron" \
  --target "web" \
  --summary "Published blog post '2026-07-31-cross-channel...' at https://www.smfclearinghouse.com/blog/2026-07-31-cross-channel-context-bridges-for-hermes-agents" \
  --profile liam

This post itself was produced and will be logged by exactly this mechanism (see end of post).

The cron entry in Hermes is typically:

hermes cron create "0 9 * * 2,4" \
  --skills "smf-works,cross-channel-context" \
  --query "Run the scheduled publishing workflow for the Clearinghouse blog. After publishing, log the action via bridge.py."

Skill preloading ensures bridge.py (or the skill wrapper) is available.

2. Gateways and Messaging Platforms

In gateway handlers, after sending a message to Telegram/Discord/etc.:

# After successful send
subprocess.run([
    "python3", BRIDGE_SCRIPT, "log",
    "--user", canonical_user,
    "--platform", "telegram",
    "--target", target_handle,
    "--summary", summary_text[:200],
    "--profile", os.getenv("HERMES_PROFILE", "liam")
], check=False)

Before the agent processes an inbound message, run a lookup and prepend:

Recent cross-channel context (last 90 minutes):
- 2026-07-31T08:12:00Z [web] Published blog post X at URL Y

Inject this into the system prompt or as a tool result. Keep it short — the bridge is a signal layer, not a full memory store.

3. Web / Workspace Frontends (Hermes Hub, etc.)

The same pattern applies when the agent is invoked via API or Hub. Log the "published" or "delivered" event with platform web.

4. Multi-Profile Coordination

When running multiple profiles (liam, harry, drj, etc.), scope lookups with --profile. This prevents one profile's activity from polluting another's context while still allowing a human operator to see the full picture via broad lookup --user michael.

Production Hardening and Observability

  • Log rotation: The JSONL grows slowly. For high-volume setups, add a simple size-based rotator (e.g., keep last 5000 lines or use logrotate on the file).
  • Idempotency: Before logging, optionally check the last N entries for a near-identical summary within a short window.
  • Failure modes:
    • Bridge script missing → agent should still complete the primary task; log a warning.
    • JSONL corruption → the lookup gracefully skips bad lines.
    • High volume → add --limit and time windows aggressively.
  • Stats command: Periodically surface python3 $SCRIPT stats in health scans or watchdog crons.
  • Backup: The file is small; include ~/.hermes/profiles/*/data/sent-messages.jsonl in any profile export or backup.

Table: Common Pitfalls

Pitfall Symptom Fix
Forgetting the log call after send Next reply has amnesia Make the log step part of every send_message wrapper or post-action hook
Using raw user strings without canonicalize "michael" and "mikesai1" treated as different users Always canonicalize on both log and lookup
No time window Old irrelevant context pollutes every reply Default to 60–180 minutes; make adjustable
Injecting raw JSON into prompt Token waste + formatting noise Summarize or render as bullet list in the wrapper
Profile not passed Cross-profile leakage Explicit --profile on every call
Bridge path hard-coded to wrong profile Cron on liam uses wrong log Use the resolved get_log_path() logic or env var

Decision Tree for Context Injection

Inbound message arrives
├── Is there a user identity? → No → treat as new session
└── Yes
    └── Run bridge lookup (--minutes 90, --count 6)
        ├── 0 results → normal processing
        └── N results
            └── Prepend "Recent cross-channel activity for this user:" + bullet list
                └── Continue with normal agent loop (tools, planning, response)

Keep the injected block under ~400 tokens. It is a hint, not the full history.

Real-World Example: This Post's Own Cron

This post was researched, written, hero-generated (abstract SVG, validated with ET.parse), built, and will be committed/pushed by a Hermes cron running on the liam profile. After the successful push and deploy verification:

python3 ~/.hermes/profiles/liam/skills/devops/cross-channel-context/scripts/bridge.py log \
  --user "michael" \
  --platform "web" \
  --target "cli" \
  --summary "Published blog post 'Cross-Channel Context Bridges for Hermes Agents' at https://www.smfclearinghouse.com/blog/2026-07-31-cross-channel-context-bridges-for-hermes-agents" \
  --profile liam

Any subsequent reply from Michael on Telegram, the web workspace, or even a follow-up cron will see this entry in a lookup.

Related Patterns

  • Built-in memory (~/.hermes/MEMORY.md) for durable facts and preferences.
  • Session store inside Hermes for within-platform continuity.
  • Honcho / Mem0 for semantic recall when you need retrieval-augmented history.
  • Profile isolation (see "Hermes Profiles & API Servers for Multi-Agent Isolation") to keep the bridge per-profile while the human operator sees the union.

The bridge is deliberately minimal: one file, no new dependencies, works in cron, gateway, and CLI. It complements rather than replaces richer memory systems.

Next Steps for Your Setup

  1. Copy or symlink bridge.py into your profile's skills or ~/.local/bin.
  2. Add the log call after every significant outbound action in your agents and crons.
  3. Wire a lookup step into your inbound handlers or prompt builders (or call it from a wrapper skill).
  4. Add a weekly watchdog cron that runs bridge.py stats and surfaces anomalies.
  5. When you spin up a new profile, seed the USER_ALIASES and test canonicalization.

Once the bridge is in place, switching channels stops feeling like starting over. The agent remembers what it told you yesterday on Telegram when you reply today on the web.

Post-verification commands (run after push):

cd ~/aiclearinghouse-site
npm run build
curl -sI -L https://www.smfclearinghouse.com/blog/2026-07-31-cross-channel-context-bridges-for-hermes-agents | head -5
# Expect 308 → 200 for the post; 200 for the hero SVG

This workflow (research → write → hero SVG → build → commit → push → verify → cross-channel log) is itself the subject of prior posts on scheduled publishing crons. The bridge makes the human side of that loop reliable.
