Runtime registration and fallback adapters

How /hep-build, /hep-network, /hep-cloud, /hep-search, /hep-call, and /hep-upload get registered per external LLM runtime, and what to do where automatic command registration is not possible. Agentlas Terminal and the Agentlas app are native surfaces: users should be able to describe the task in plain language without typing a Hephaestus command.

Two universal surfaces underpin everything (installed by the one-touch installer):

• Runtime home — ~/.agentlas/runtime/current/bin/hephaestus is the runtime-neutral runner every adapter resolves first.
• Universal skill — ~/.agents/skills/hephaestus-network/SKILL.md (AgentSkills spec) is read natively by Codex, OpenCode, OpenClaw, Cursor, and Crush.

Runtime	Registration	Mechanism
Claude Code	automatic	plugin install (commands + hephaestus-network skill) + ~/.claude/commands/*.md; plugin SessionStart and UserPromptSubmit hooks inject bounded local ontology recall
Codex	automatic	codex plugin add hephaestus@agentlas-core-engine + explicit $hephaestus-network skill + local MCP in ~/.codex/config.toml; Codex 0.117+ removed custom prompts, and the mirrored plugin hooks use the same point-of-need recall contract
Gemini CLI	automatic (partial)	gemini extensions install … (commands TOML + skill) + fallback TOML copied to ~/.gemini/commands/
Antigravity	automatic	global workflow copied to ~/.gemini/antigravity*/global_workflows/; the installer merges a named agentlas-memory PreInvocation hook into ~/.gemini/config/hooks.json, returning injectSteps[].ephemeralMessage
Grok CLI	automatic with passive-hook limit	global SessionStart/UserPromptSubmit hooks write a bounded workspace-scoped capsule under ~/.agentlas/runtime-memory-context/grok/. Grok ignores passive-hook stdout, so a managed block in ~/.grok/AGENTS.md points the model at the exact-workspace capsule; this is not direct dynamic hook injection.
Cursor	automatic	commands → ~/.cursor/commands/ (IDE + agent CLI), skill → ~/.cursor/skills/ and ~/.agents/skills/; cursor/plugin/ is the marketplace-ready plugin bundle; cursor/rules/hephaestus.mdc remains the per-project rule fallback
OpenCode	automatic	commands → ~/.config/opencode/commands/ → /hep-network; skill via ~/.agents/skills; MCP via opencode.json (see opencode/README.md). A dependency-free global plugin uses chat.message plus experimental.chat.system.transform, and preserves the capsule through experimental.session.compacting.
OpenClaw	automatic	AgentSkills skill → ~/.openclaw/skills (or openclaw skills install --global); invoke /skill hephaestus-network <request>; exec-tool gated on python3
Hermes Agent	automatic	AgentSkills skill → ~/.hermes/skills/; MCP server in ~/.hermes/config.yaml (see hermes/README.md)
Agentlas native	automatic	Agentlas Terminal and the Agentlas app route plain language through native Agentlas/Hephaestus tools. Build, network, cloud, call, upload, search, research, and Stormbreaker behavior are inferred from context.
Terminal shell/debug	automatic	bin/hep-build, bin/hep-network, bin/hep-cloud, bin/hep-search, bin/hep-call, bin/hep-upload, bin/hep-global, and bin/hephaestus — hep-build "<request>" builds, hep-network "<request>" borrows Hub agents, hep-cloud "<request>" uses the signed-in user's cloud packages, hep-search "<request>" compares Cloud/Hub candidates, hep-upload <agent-folder> asks Cloud-vs-Hub before any upload, hep-call "agent-a,agent-b" "<context>" prepares exact agents, and `hep-global install
Ollama / Gemma / DeepSeek local models	via harness or MCP	ollama launch <harness> then use that harness's surface above; or register hephaestus mcp serve (stdio MCP, tools hephaestus_route / hephaestus_network_status); raw API loops use an OpenAI-tools function — see docs/local-models.md
Generic AGENTS.md runtimes	manual fallback	the AGENTS.md command alias section; the runtime reads AGENTS.md and treats /hep-* or @Hephaestus as the routing contract

Realistic limits, stated plainly:

• Current Codex invokes plugin skills explicitly as $hephaestus-network. Custom /prompts:* commands were removed in Codex 0.117 and are retained in this repository only as legacy source for older hosts.
• Claude Code and Codex receive real hook-provided additionalContext on each prompt. Antigravity receives an ephemeral pre-invocation step. OpenCode receives a system-prompt transform. Grok lifecycle hooks are passive, so its adapter can refresh a local capsule but cannot inject hook stdout directly.
• Memory hooks run only when an ancestor project contains a project ontology database or a cryptographically verified routing card whose exact agent projection exists. They never read a host transcript, call a server embedding API, or create Memory Curator tickets. Project recall is public/internal; private experience is eligible only for that verified exact slug and its hub-agents/<slug>/memory/experience.sqlite projection.
• The capsule has a deterministic digest and is re-injected at point of need; equal digests are one context item, and the newest capsule is re-applied after compaction. This supplements AGENTS.md/CLAUDE.md instead of copying their policy text.
• Cursor command files are plain Markdown with no templating; arguments typed after the command are appended to the prompt automatically.
• AGENTS.md-only runtimes still cannot register slash commands — the fallback is an instructions file, copied per project.
• Local model runtimes vary; the universal contract is: (1) read AGENTS.md or the skill, (2) call hephaestus route (shell) or hephaestus_route (MCP), (3) honor the decision JSON. The router does not execute tools; host runtime permissions apply when an agent actually acts.
• If command registration fails anywhere, the terminal shell/debug form works: hep-build "<request>", hep-network "<request>", or hep-cloud "<request>".

First-use memory behavior: whichever runtime calls the router first triggers network init (also run by the installer). All runtimes reuse the project ontology plus the same agent-scoped, rebuildable SQLite projections under ~/.agentlas/networking/hub-agents/; no runtime owns a divergent memory copy. The v1.1.40 install verifies the bundled local Model2Vec asset as the primary 352-dimensional hybrid embedding path. If that asset is absent or rejected, the capsule reports retrieval=degraded_hash and uses local hash-96; it never downloads a model or sends text to a server.
