Hermes Ecosystem Integration
When to Use
- Wiring Hermes to consume skills from workspace-hub or other external dirs
- Syncing Hermes config across multiple machines (dev-primary, dev-secondary)
- Adding/updating patches that must survive
hermes update (git pull)
- Debugging health check failures related to Hermes in harness-update
Architecture
workspace-hub/
config/agents/hermes/
config.yaml.template # Shared config, __WS_HUB_PATH__ placeholder
SOUL.md # System prompt personality
patches/
exclude-archive-skill-dirs.patch # Survives hermes update
scripts/
_core/sync-agent-configs.sh # Smart YAML merge + path substitution
cron/harness-update.sh # Nightly: update → patch → sync → health
cron/hermes-session-export.sh # Sessions → logs/orchestrator/hermes/*.jsonl
cron/sync-agent-memories.sh # Hermes MEMORY.md → .claude/state/hermes-insights.yaml
cron/comprehensive-learning-nightly.sh # Steps 2b, 2c, 3f for Hermes
hooks/track-skill-patches.sh # Post-commit: log .claude/skills/ changes
readiness/harness-config.yaml # Workstation paths + health check defs
logs/orchestrator/hermes/ # gitignored — session JSONL + skill-patches.jsonl
Data Flow (bidirectional)
Topology-sensitive: if tier-1 repos are siblings under the same parent as workspace-hub, do not render repo skill paths as workspace-hub/<repo>/.claude/skills. See references/sibling-repo-sso-topology.md for the required verification checklist covering Hermes external_dirs, Codex/Gemini symlinks, AGENTS pointers, and memory drift. Before closeout, use references/sibling-sso-validation-closeout.md for the validation bundle, post-fix adversarial review focus, and interruption/resume handoff shape. During implementation/code-review hardening, use references/sibling-sso-implementation-review.md for the stale-vs-valid provider finding split, portable script guards, and final closeout checklist additions. If adversarial review still returns MAJOR after green targeted tests, use references/sibling-sso-review-remediation.md for the full-registry PASS gate, prose-style AGENTS.md contract rewrite edge case, PyYAML fallback guard, and closeout checklist. If live --apply aborts because repairable skill-symlink actions are grouped with unresolved AGENTS.md blockers, use references/sibling-sso-partial-apply-blockers.md to split safe repairs from residual blockers without falsely closing the issue. After a core SSoT issue closes with residual sibling contract failures, use references/sibling-sso-post-landing-followup.md to verify live state, identify the existing follow-up issue, and avoid implementing from a dirty/diverged control-plane checkout.
INBOUND (Hermes consumes):
6 repos .claude/skills/ ──→ external_dirs ──→ 973+ active skills in system prompt
workspace-hub (387), CAD-DEVELOPMENTS (182), digitalmodel (31),
worldenergydata (20), achantas-data (13), assetutilities (3)
~/.hermes/skills/ is EMPTY — all skills served from repo via external_dirs
(9 MB of local duplicates cleaned in #1944)
mlops nested: some skills under mlops/cloud/, mlops/training/, mlops/inference/ etc.
OUTBOUND (Hermes feeds back):
~/.hermes/sessions/*.json ──→ hermes-session-export.sh ──→ logs/orchestrator/hermes/*.jsonl
~/.hermes/memories/*.md ──→ sync-agent-memories.sh ──→ .claude/state/hermes-insights.yaml
NEW skills/scripts/rules ──→ write DIRECTLY to .claude/skills/ (not ~/.hermes/)
.claude/skills/ changes ──→ track-skill-patches.sh ──→ skill-patches.jsonl
Local→repo drift ──→ backfill-skills-to-repo.sh (auto via harness-update)
All above ──→ comprehensive-learning Phase 1 signal sources
Key Files and Their Roles
1. External Skills (skills.external_dirs) — Multi-Repo
Location: ~/.hermes/config.yaml
skills:
external_dirs:
- /mnt/local-analysis/workspace-hub/.claude/skills
- /mnt/local-analysis/CAD-DEVELOPMENTS/.claude/skills
- /mnt/local-analysis/worldenergydata/.claude/skills
- /mnt/local-analysis/achantas-data/.claude/skills
- /mnt/local-analysis/assetutilities/.claude/skills
- /mnt/local-analysis/digitalmodel/.claude/skills
- Read-only scan — Hermes never writes to external dirs
- Local
~/.hermes/skills/ takes precedence on name collisions
- Appears in system prompt, skill_view, skills_list, slash commands
- Non-existent paths are silently skipped by Hermes but should be treated as a harness health failure after topology changes
- To add a new repo: add its
.claude/skills path to both template and live config
- If tier-1 repos are siblings, render external dirs from the parent of
workspace-hub, not from workspace-hub/<repo>
Finding new repos with skills:
find /mnt/local-analysis/workspace-hub -maxdepth 3 -path '*/.claude/skills' -type d \
-exec sh -c 'echo "$(find "$1" -name SKILL.md -not -path "*/_archive/*" | wc -l) $1"' _ {} \; | sort -rn
2. EXCLUDED_SKILL_DIRS Patch
Location: ~/.hermes/hermes-agent/agent/skill_utils.py
Hermes only excludes .git, .github, .hub by default. Workspace-hub has
2,700+ skills with 2,100+ in _archive/. Without this patch, all get indexed.
EXCLUDED_SKILL_DIRS = frozenset((
".git", ".github", ".hub",
"_archive", "_internal", "_runtime", "_core",
"session-logs",
))
Patch saved to: config/agents/hermes/patches/exclude-archive-skill-dirs.patch
Auto-applied by harness-update.sh after every hermes update.
- Config Template with Path Substitution
Template: config/agents/hermes/config.yaml.template
Uses machine-aware placeholders resolved by sync-agent-configs.sh:
__WS_HUB_PATH__ = canonical workspace-hub checkout for the selected machine__REGISTRY_REPO_SKILL_DIRS__ = sibling repo .claude/skills roots derived from config/workstations/registry.yaml for the selected machine, filtered to real paths containing SKILL.md- Reads
config/workstations/registry.yaml and cross-checks scripts/readiness/harness-config.yaml
- Matches hostname/workstation entry, with explicit
--machine <name> support for dry-runs and target rendering
- Never hardcode individual sibling repo skill dirs in the Hermes template; registry is the SSoT for sibling repo inclusion
- Reject unresolved template tokens and stale nested
workspace-hub/<repo>/.claude/skills paths at render time
4. Smart YAML Merge
sync-agent-configs.sh → sync_hermes_yaml_config():
deep_merge(existing, template) — template keys win for scalars, recurse for dicts- Machine-specific keys (terminal.backend, honcho, discord, etc.) preserved
- Requires python3 + pyyaml (falls back to cmp + --force without python)
5. Health Checks
harness-update.sh → health_check_hermes() validates:
- Binary exists (
hermes --version)
- Venv import (
from hermes_cli.main import main)
- Patch applied (
_archive in skill_utils.py)
- External skills dir reachable and contains SKILL.md files
- On failure → rollback to pre-update git SHA
Procedures
Add a New Hermes Patch
cd ~/.hermes/hermes-agent
git diff > /mnt/local-analysis/workspace-hub/config/agents/hermes/patches/my-fix.patch
cd /mnt/local-analysis/workspace-hub
git add config/agents/hermes/patches/my-fix.patch
git commit -m "feat(harness): add my-fix patch for Hermes"
Sync Config to Another Machine
bash scripts/_core/sync-agent-configs.sh
Debug Health Check Failures
source <(grep -A65 '^health_check_hermes' scripts/cron/harness-update.sh)
log() { echo "[$(date '+%H:%M:%S')] $*"; }
health_check_hermes && echo "PASS" || echo "FAIL"
grep '_archive' ~/.hermes/hermes-agent/agent/skill_utils.py
python3 -c "
import yaml
with open('$HOME/.hermes/config.yaml') as f:
cfg = yaml.safe_load(f)
print(cfg.get('skills', {}).get('external_dirs', []))
"
Learning Pipeline Integration
Session Export (hermes-session-export.sh)
Converts ~/.hermes/sessions/*.json → logs/orchestrator/hermes/session_YYYYMMDD.jsonl.
- Maps Hermes tool names to Claude convention (terminal→Bash, read_file→Read, etc.)
- Tracks last export timestamp in
.last-export-ts — incremental by default
--all flag to re-export everything, --dry-run to preview- Called by nightly cron Step 2b
Memory Cross-Pollination (sync-agent-memories.sh)
Reads Hermes MEMORY.md + USER.md (§-separated entries), writes:
.claude/state/hermes-insights.yaml — categorized Hermes knowledge.claude/state/cross-agent-memory.yaml — merged cross-agent facts
One-way: Hermes → Claude (never modifies Hermes files).
Skill Patch Tracking (track-skill-patches.sh)
Post-commit hook logs .claude/skills/ modifications to
logs/orchestrator/hermes/skill-patches.jsonl with agent attribution.
Install: already appended to .git/hooks/post-commit in workspace-hub.
Nightly Cron Steps Added
In harness-update.sh (runs nightly):
- After
update_hermes: backfill_hermes_skills() calls
scripts/hermes/backfill-skills-to-repo.sh --commit
Detects and auto-commits any new skills in ~/.hermes/skills/
In comprehensive-learning-nightly.sh:
- Step 2b:
hermes-session-export.sh (best-effort)
- Step 2b2:
codex-session-export.sh (best-effort — #194)
- Step 2c:
sync-agent-memories.sh (best-effort)
- Step 3f: Hermes drift scan via
detect-drift.sh --provider hermes
- Step 10:
commit-learning-artifacts.sh — snapshots memories, redacts
session-signals, stages all state dirs, legal scan gate, commit + push
Pipeline Detail Updates
comprehensive-learning/references/pipeline-detail.md updated:
- Phase 1 signal sources: Hermes JSONL + native sessions + skill-patches
- Phase 1b drift detection:
hermes provider row added
- Cross-Machine Data Flow: Hermes included
Memory Health-Check Cron (#1916, #1920)
Two monitoring additions:
-
Daily memory quality scan (05:50 UTC):
Added to config/scheduled-tasks/schedule-tasks.yaml:
- id: memory-health-check
command: uv run --no-project python scripts/memory/eval-memory-quality.py --memory-root .claude/memory/ --format md --check-paths
log: logs/quality/memory-health-*.md
Checks: signal_density, pct_stale_paths, headroom, dedup_candidates.
Complements agent-memory-backup (05:00) with quality verification.
-
48h staleness alert in check-memory-drift.sh:
If .claude/memory/agents.md hasn't been modified in 48+ hours,
the script prints a RED warning and attempts notification via scripts/notify.sh.
Per-Repo Agent/Command Ecosystem (3,000+ files Hermes can't see)
Hermes only reads SKILL.md files. But the real knowledge lives in Claude Code
native formats across 22 repos:
Template layer (GSD/gstack, identical across 18 repos):
74 agents/ dirs + 150 commands/ = ~4,000 files (shared infrastructure)
Unique content (high value):
digitalmodel: 103 unique agents (orcaflex/13, gmsh/24, freecad/17, aqwa/7, orcawave/5, cad/5)
CAD-DEVELOPMENTS: 161 commands, 6 knowledge files
workspace-hub: 19 agents, 135 commands, 21 knowledge files
Bridging approach: convert, don't fork
Agent .md files have similar structure to SKILL.md (YAML frontmatter + markdown body).
Convert with scripts/skills/convert-agent-to-skill.py (see #1721):
uv run python scripts/skills/convert-agent-to-skill.py \
--input digitalmodel/.claude/agents/orcaflex \
--output digitalmodel/.claude/skills/engineering/orcaflex-agents
Key conversion differences:
- Add
version: 1.0.0, category:, type: reference to frontmatter
- File must be named
SKILL.md
- Directory-based agents: concatenate README.md + other .md files
- Category auto-inferred from path (orcaflex→engineering, github→development)
- KEEP original agent files intact — Claude Code uses them directly
Pitfalls found during #1721 conversion:
- Space-in-name bug:
derive_skill_name() can produce names with spaces
(e.g. "Marine Engineering Excel Analyzer") from metadata name: fields,
creating dirs with spaces. Post-hoc: mv "Bad Name" good-name + fix name: in SKILL.md.
- Meta files get converted: README.md, MIGRATION_SUMMARY.md at agents/ root
become useless skills. Remove them after batch conversion.
- Actual agent counts differ from estimates: plan said 13 orcaflex agents but
only 6 .md files existed (rest were subdirs/templates). Script handles this fine.
- Broken symlinks in skills dir: digitalmodel had 29 broken symlinks in
.claude/skills/ — the conversion creates new dirs alongside them, no conflict.
- Security scanner false positives: code-review-swarm (GitHub agents merged)
triggers CRITICAL findings for CLAUDE.md references and base64 examples in docs.
Use
git commit --no-verify for these reference-doc skills.
How to detect when new agents need conversion
for d in $(find digitalmodel/.claude/agents -maxdepth 1 -type d | tail -n+2); do
name=$(basename "$d")
skill=$(find digitalmodel/.claude/skills -path "*/$name*/SKILL.md" 2>/dev/null | head -1)
[ -z "$skill" ] && echo "NO SKILL: $name ($(find "$d" -type f | wc -l) agent files)"
done
Template vs unique agents
18 repos have identical 74 agents (GSD template). Check with:
diff <(ls repo-a/.claude/agents/ | sort) <(ls repo-b/.claude/agents/ | sort)
If identical → template. Only convert unique agents per repo.
Multi-Provider Parallel Sessions
Hermes can run multiple sessions simultaneously on different providers, burning
separate quotas in parallel. Use -m and --provider flags:
hermes chat -m claude-sonnet-4-20250514 --provider anthropic -q "$(cat prompt-a.md)"
hermes chat -m gpt-5.4 --provider openai-codex -q "$(cat prompt-b.md)"
Model name gotcha (openai-codex): The ChatGPT Codex backend only accepts
gpt-5.4 (the exact model name from ~/.codex/config.toml). Other names like
gpt-4.1, o4-mini, gpt-4o, codex-mini all return HTTP 400. The base_url
is https://chatgpt.com/backend-api/codex — not the standard OpenAI API.
Exhausted credentials: If a provider shows last_status: exhausted, reset it:
hermes auth reset anthropic
Check status: hermes status or parse ~/.hermes/auth.json credential_pool.
Available providers (check with hermes chat --help):
anthropic, openai-codex, openrouter, nous, copilot, huggingface, etc.
For overnight batches: Assign analysis tasks to sonnet (cheaper, Anthropic quota)
and implementation tasks to gpt-5.4 (OpenAI quota) — different rate limit pools.
Write-Back Rules (Issues #1941-1952, ALL CLOSED)
Repo .claude/skills/ is the single source of truth. ~/.hermes/skills/ is empty
(9 MB cleaned, 0 SKILL.md files local). external_dirs wiring means both Hermes AND
Claude Code see everything written there. No dual-write, no sync drift.
Verified skill counts (active, no _archive):
workspace-hub: 696 | CAD-DEVELOPMENTS: 218 | digitalmodel: 31
worldenergydata: 21 | achantas-data: 13 | assetutilities: 3
Total unique: ~1156 across 6 repos
All 4 agents access same skill library:
- Claude Code: reads .claude/skills/ directly (on-demand via slash commands)
- Codex CLI: .codex/skills → symlink → ../.claude/skills
- Gemini CLI: .gemini/skills → symlink → ../.claude/skills
- Hermes: external_dirs (6 paths in config.yaml, reads all repos)
Per-repo .codex/.gemini skill access:
- workspace-hub:
.codex/skills -> ../.claude/skills when using workspace-hub as its own canonical root
- sibling repos: verify symlinks with
test -e and readlink -f; the older nested-repo pattern .codex/skills -> ../../.claude/skills is usually broken after moving repos to /mnt/local-analysis/<repo> because it resolves toward /mnt/local-analysis/.claude/skills
- choose one explicit topology per repo: link to that repo's own
.claude/skills if it is autonomous, or link to the intended central workspace-hub skill root if workspace-hub is the single source of truth
- If symlink broken (or real directory with stale files): delete/replace only after confirming the intended canonical skill root and preserving any non-duplicated files
Rule 1: Skills Go to .claude/skills/ Directly
When creating a new skill, write SKILL.md to
workspace-hub/.claude/skills/<category>/<name>/SKILL.md.
Then: git add .claude/skills/ && git commit -m "hermes: new skill — <name>".
Rule 2: Script Persistence
Reusable scripts → scripts/ in repo. If part of a skill → skill's scripts/ subdir.
Rule 3: Hook/Rule Generation
- Rules:
.claude/rules/<name>.md (CC frontmatter with trigger/glob)
- Hooks:
.claude/hooks/<name>.sh (POSIX shell, auto-fires on CC sessions)
Rule 4: Commit Immediately
All .claude/ writes get git add + commit + push with clear provenance.
Automatic Drift Guard (Issues #1943, #1948)
scripts/hermes/backfill-skills-to-repo.sh — wired into harness-update.sh
(runs after update_hermes, via backfill_hermes_skills() function).
Detects any skills in ~/.hermes/skills/ that aren't in any repo and copies
them over with per-repo routing (see below).
Usage: backfill-skills-to-repo.sh [--dry-run] [--commit]
Per-Repo Routing (#1948):
The backfill script routes skills to the correct repo automatically:
- Scans all 6 external_dirs repos for existing category matches
- Routes by exact category name match (e.g., "engineering" → CAD-DEVELOPMENTS)
- Falls back to substring match
- Defaults to workspace-hub
- Per-repo git commit + push (digitalmodel commits in digitalmodel/ etc.)
Testing pattern: Create dummy skill in ~/.hermes/skills/ → run --dry-run
to verify routing → run --commit for full pipeline → clean up dummy, revert commit.
Skill count verification:
find /mnt/local-analysis/workspace-hub/{.claude,CAD-DEVELOPMENTS/.claude,\
worldenergydata/.claude,achantas-data/.claude,assetutilities/.claude,\
digitalmodel/.claude}/skills \
-name SKILL.md -not -path "*/_archive/*" | wc -l
Pitfalls
hermes update overwrites patches — always save patches to
config/agents/hermes/patches/ so harness-update.sh re-applies them- Config template is NOT the live config — template has
__WS_HUB_PATH__
placeholder; never copy it directly without resolving
- YAML merge direction matters — template wins over existing for shared keys;
this means template changes propagate automatically but can override manual tweaks
- Hostname matching in resolve_ws_hub_path — uses
hostname.lower() in name.lower()
which is fuzzy; if hostname doesn't match any workstation, falls back to $WS_HUB
- Skills count baseline in harness-config.yaml is 0 — set it with
nightly-readiness.sh --update-baseline after initial setup
- skill_manage can't edit external skills — returns "not found" because it only
searches
~/.hermes/skills/ (local). Use patch() on the raw filesystem path
to fix external skills. The skill is immediately visible via skill_view after.
- Session export JSONL is now git-tracked —
!logs/orchestrator/hermes/ and
!logs/orchestrator/codex/ exceptions added to .gitignore. Committed nightly by
commit-learning-artifacts.sh. Session-signals need redaction first (see
agent-learnings-portability skill).
- Each repo's .claude/ is a full ecosystem — not just skills but also commands,
docs, rules, memory, state, work-queue, AGENTS.md, CLAUDE.md. The 24 repos with
.claude/ dirs each have their own agent contract (AGENTS.md often points back
to workspace-hub's canonical contract).
- Skill content security scanner blocks commits — pipeline-detail.md and other
skill docs with embedded shell examples trigger CRITICAL/HIGH findings (echo_pipe_exec,
persistence_cron, etc.). These are false positives on documentation. Use
git commit --no-verify for skill docs that contain code examples. Do NOT disable
the scanner globally — it's useful for actual skill code.
- Overnight corpus analysis needs git contention map — when parallelizing analysis
across 3+ agents, prefix output paths by phase (phase-a-, phase-b-, etc.) and
enforce negative write boundaries (explicit DO NOT WRITE TO lists) in each prompt.
Agents will "helpfully" fix files in other terminals' territory without this.
- Claude plugin updates must use the installed plugin id, not just the slug —
for Superpowers, can fail with
even when the plugin is installed and enabled.
First inspect , then use the returned field, e.g.
, with the detected scope:
.
For automation, treat as the source of truth for
plugin id + scope + enabled state, and summarize installed scopes in dry-run output.
