Scott Idem 1cc7988953 feat: add shell_exec tool and fix orchestrator model name resolution
- Add shell_exec to orchestrator tool suite (system.py + __init__.py)
  Runs arbitrary shell commands on the Cortex host with timeout (1–120s),
  combined stdout/stderr output, optional working_dir, and exit code reporting.
  Enables system diagnostics (df, ls, ps, journalctl, etc.) from Agent mode.

- Fix orchestrator_engine.run() to use model_name from resolved registry entry
  Previously used settings.orchestrator_model (.env hardcode) regardless of
  what model was assigned to the orchestrator role. Now accepts model_name param
  and falls back to settings value only when registry has no model_name.

- Update ARCH__FUTURE.md: date, running host, local orchestrator status,
  model registry V2 progress, added Cortex Mesh concept (section 9)

Architecture: Planned Features

What's next and how it's designed to work. Last updated: 2026-04-28

For the current task list see TODO__Agents.md. For phases and priorities see ROADMAP.md.


1. Local Orchestrator

Status: Partially built — openai_orchestrator.py exists and is wired into POST /orchestrate. If the orchestrator role in the model registry resolves to a local_openai model, it routes there automatically. Full parity with the Gemini orchestrator (tool loop quality, error handling, context budget enforcement) is still in progress.

Same ReAct tool loop as the Gemini API orchestrator, but driven by a local model via Open WebUI's OpenAI-compatible API. Enables offline/private agent tasks with no API cost.

Why local models work for this now: Gemma 4 E4B and 26B A4B both support OpenAI tools / tool_choice function calling. The tool schema is nearly identical to Gemini's FunctionDeclaration — minor field renaming only.

Design:

POST /orchestrate  (mode: "local")
    ↓
local_orchestrator_engine.py
    • converts tools/ to OpenAI tools format
    • POST /api/chat/completions with tools array
    • parse tool_calls response
    • execute tool, append result
    • loop until finish_reason: "stop"
    ↓
response returned (local model generates final answer)

Model selection:

  • Gemma 4 E4B (25 t/s, 72k ctx) — interactive/fast tasks
  • Gemma 4 26B A4B (9 t/s, 50k ctx) — heavier reasoning, background tasks

Context budget per iteration (system prompt + memory + tool results + history):

  • Small model: budget ~40-50k tokens per round
  • Medium model: budget ~35-40k tokens per round

2. Dev Agent Pipeline

Status: Design complete, not yet built.

Accept a plain-English task, implement code changes, verify them, and present for human approval before committing.

Task (chat / Gitea issue / Kanban)
    ↓
Orchestrator — reads relevant files, routes to specialist
    ↓
Specialist Agent (Claude CLI in project directory)
    • implements the change
    • runs self-check: py_compile / svelte-check
    ↓
Supervisor Agent
    • reviews the diff
    • runs test suite
    • returns: PASS / NEEDS_REVIEW / FAIL + reason
    ↓
Human approval gate
    • summary in Cortex UI or NC Talk
    • approve → commit (+ optional push)
    • reject <20><> feedback back to specialist

Specialists (both Claude CLI):

  • Frontend — working dir: ~/OSIT_dev/aether_app_sveltekit/ — runs svelte-check after every change
  • Backend — working dir: ~/OSIT_dev/aether_api_fastapi/ — runs py_compile + unit tests

Supervisor returns structured JSON:

{
  "verdict": "PASS | NEEDS_REVIEW | FAIL",
  "checks_passed": ["py_compile"],
  "checks_failed": [],
  "review_notes": "...",
  "commit_message": "..."
}

3. Gitea Integration

Status: Not started. pfSense port forward for SSH already confirmed working.

  • Webhooks → Cortex: push/PR/issue events → POST /webhook/gitea → orchestrator
    • Router pattern already established; add cortex/routers/gitea.py
  • Gitea Actions CI: .gitea/workflows/check.yml — run py_compile/svelte-check on push
  • Cortex → Gitea: after human approval, call Gitea API to create PR or push branch

SSH clone/push: git clone ssh://git@git.dgrzone.com:2222/<user>/<repo>.git


4. Knowledge Layer (AE Journals)

Status: Tools exist, import script not yet built.

AE Journals becomes the searchable long-term knowledge base. Complements memory distillation: memory files cover "what have we been working on lately"; Journals cover "what do I know about topic X".

Existing tools: ae_journal_search, ae_journal_entry_create — already in orchestrator tool suite.

Import script (to build):

  • Walk a markdown directory (Nextcloud, agents_sync docs)
  • Chunk by H2 section
  • Search before creating (deduplication)
  • Tag from frontmatter, filename, directory path
  • Target sources: ~/DgrZone_Nextcloud/, ~/OSIT_Nextcloud/

Agent workflow:

"Summarize my notes on WireGuard setup"
    → orchestrator calls ae_journal_search("wireguard")
    → returns matching entries
    → Claude synthesizes response

5. Intelligent Model Routing

Status: Partially addressed. Model Registry V2 (2026-04-27) introduced role-based routing — chat, orchestrator, distill, coder, research roles each have their own primary/backup model chain, and the UI role toggle lets users manually select which role handles a message. Automatic task-characteristic routing (below) is still deferred.

Route automatically based on task characteristics rather than requiring manual backend selection:

Task type Backend Reason
User-facing conversation Claude Quality prose, persona fidelity
Tool use / orchestration Gemini API Native function calling, free tier
Private / sensitive / offline Local (Ollama) No data leaves the network
Long context (>50k tokens) Gemini 2.0 1M token context window
Fast/cheap simple queries Local (E4B) 25 t/s, no API cost

Routing logic would live in llm_client.py or a new router.py — map task metadata to backend choice.


6. RAG via Open WebUI

Status: Future — Open WebUI already supports it.

Feed Nextcloud documents or session logs into Open WebUI knowledge collections. Reference them in local model chat via "files": [{"type": "collection", "id": "..."}].

Would complement AE Journals for local-only contexts where data shouldn't leave the network.

API reference: docs/OPEN_WEBUI_API.md — RAG section.


8. Agent Architecture Ideas (from Claude Code leak)

Status: Research — review before building dev agent pipeline and orchestrator.

The Claude Code system prompt was leaked in early April 2026. Two reimplementation repos are worth reading for design ideas before building out the dev agent pipeline and local orchestrator:

Ideas worth incorporating:

Tiered permission architecture — explicit read-only / write / shell / unsafe modes, each requiring an opt-in flag. Currently Cortex has implicit trust for agent operations. Relevant once the dev agent pipeline is writing and executing code — don't want a brief cron job accidentally in write mode.

Agent lineage tracking — agent manager records which agent spawned which sub-agent. Useful for debugging multi-step orchestrated tasks and essential for the supervisor → specialist → approval gate chain.

Cost/budget enforcement — hard token and cost budgets per operation, multiple budget types. ORCHESTRATOR_MAX_ROUNDS=10 is Cortex's only guardrail today. Worth adding a token budget check to the tool loop, especially relevant for local models with hard context ceilings (72k/50k practical).

Context compaction/snipping — automatic mid-session context trimming when approaching limits. Important for long orchestrator runs against local models. Could trim tool results that are no longer needed for the current reasoning step.

Nested agent delegation with dependency-aware batching — sub-agents that know their parent; parallel sub-tasks batched by dependency order. Directly applicable to the dev agent pipeline (orchestrator → specialist → supervisor, with some steps parallelizable).

File history journaling — beyond session logs, a journal of what files changed and why, with replay summaries. Different from memory distillation — more like a git log for agent actions. Could complement the supervisor agent's diff review.

Plugin/manifest-based tool extensions — tools declared via manifest rather than hardcoded in __init__.py. Would make adding new orchestrator tools less invasive. Worth considering before the tool suite grows much larger.


7. Permanent Fleet Hosting

Status: Deferred.

Currently running on scott-lt-i7-rtx (gaming/agents laptop). Disabled on scott_lpt (2026-04-28) — that machine is a dev/editing node only. Long-term target: home server (always-on, Docker).

docker-compose.yml already exists in the project root. Deployment path:

  1. Copy to home server
  2. Configure reverse proxy (Nginx, already Docker-hosted)
  3. Set subdomain cortex.dgrzone.com → home server internal IP
  4. WireGuard required for all access — not internet-exposed

9. Cortex Mesh (Multi-Instance Fleet)

Status: Concept — no design yet.

Rather than a single Cortex instance, each device in the fleet runs its own instance with its own persona(s), local models, and capabilities. Instances can delegate tasks to each other based on available resources and roles.

Use cases:

  • scott_lpt (edit/dev node) delegates code tasks to scott-lt-i7-rtx (GPU/Ollama host)
  • A background cron on one instance triggers an orchestrated task on another
  • Each instance has its own "best available" model — mesh routing picks the right node automatically

Design questions to resolve:

  • Auth between instances (shared JWT secret vs. per-instance API keys)
  • How instances advertise capabilities (model registry over HTTP? shared Syncthing file?)
  • Whether ae_send_message / the existing inbox system is the right coordination layer or if a dedicated Cortex-to-Cortex protocol is needed
  • Session continuity — does a conversation that starts on one node stay there, or can it migrate?

The Syncthing-synced home/ directory and shared model_registry.json already provide a natural foundation — instances share persona memory and context without a central DB.
