# NousResearch/hermes-agent · Memory context injection framing and contamination issues
## Open now
- 3 issues, 1 PR open on GitHub.
- #8893: \[Bug\]: Memory prefetch is appended to the current user message, causing prompt contamination and answer drift
- #31584: \[Feature\]: Treat memory-context as background context, not authoritative user-message content
- #66888: Memory context (format_memory_context) claims system authority but is transported inside user-role message content — trips injection-hardened personas; docs describe system-prompt injection
- PR #40967: fix(#40170): prevent Honcho memory injection on customer-facing gateways
These issues and PRs concern how recalled memory and skill context is injected into conversations — including problems with role assignment, message contamination, deduplication of markers, gateway isolation, and framing memory as background context rather than authoritative user content.
## TL;DR
- 27 member(s): 3 open issue(s), 6 closed issue(s), 1 open PR(s), 4 merged PR(s), 13 PR(s) closed without merging.
- A fix was merged to main in PR #2235. Verify it addresses your case.
- **Recommended:** read PR #2235 (and any competing PRs below) before filing. Confirm the merged change covers your symptom.
## Maintainer resolution verdict
- Internal-tracker verdict over this cluster's issue members: `partially_resolved` · deciding PR(s): `pr-2235,pr-15381,pr-75921`. This is distinct from the fix status above. Weigh it yourself.
## How this cluster was grouped
- Link evidence (`STRUCTURAL_PARTIAL`): some members are connected by structural evidence (shared changed files, or a closing/superseded reference); the rest are joined by an automated relevance judgement over their text.
- Members outside that structural core may belong to a different underlying problem.
- Pairwise link density `0.06`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.

## Closed / duplicate issues
- #2227: bug: memory/skill nudges permanently baked into user messages, polluting conversation history
- #5289: bug: hidden MemoryProvider prefetch is framed as user-visible conversation
- #5719: Bug: Honcho Context block leaking into user-visible messages via vision auto-analysis
- #40170: \[Bug\]: # Hermes Agent ” Customer-Facing Honcho Recall Leak
- #58773: Hermes Agent flags Hindsight memory context as prompt injection and refuses to treat it as authoritative
- #65891: Model switch markers (\[System: The active model...\]) pollute conversation history and permanently waste context tokens with no cleanup

+"""Tests for the ``pinPeerName`` config flag (#14984).
+
+By default, when Hermes runs under a gateway (Telegram, Discord, Slack, ...)
+it passes the platform-native user ID as ``runtime_user_peer_name`` into
+``HonchoSessionManager``. That ID wins over any configured ``peer_name``
+so multi-user bots scope memory per user.
+
+For a single-user personal deployment where the user connects over multiple
+platforms, that default forks memory into one Honcho peer per platform
+(Telegram UID, Discord snowflake, Slack user ID, ...). The user asked for
+an opt-in knob that pins the user peer to ``peer_name`` from ``honcho.json``
+so the same person's memory stays unified regardless of which platform the
+turn arrived on — ``hosts..pinPeerName: true`` (or root-level
+``pinPeerName: true``).
+
+These tests exercise both the config parsing (``client.py::from_global_config``)
+and the resolution order (``session.py::get_or_create``). We stub the
+Honcho API calls so we can assert the chosen ``user_peer_id`` without
