v0.4.4

Hephaestus Network MCP Hub invocation

• Adds hephaestus_hub_invoke, a Hephaestus Network MCP tool that invokes Agentlas Hub public agents through Hub MCP runtime bundles.
• Supports Hub-only execution with local routing skipped, local_inventory: [], and paid-slug overlap blocking.
• Bootstraps shared Agentlas memory files under ~/.agentlas/ and writes execution receipts.
• Bumps runtime adapters and one-touch install surfaces to v0.4.4.

Verification:

• 30/30 installed-runtime Hub invocation validations passed against ~/.agentlas/runtime/current/bin/hephaestus mcp serve.
• scripts/verify-package.sh passed.
• scripts/verify-one-touch-install.sh passed.

v0.3.0 — CJK search, RRF fusion, LLM search hooks, ontology-backed agents

v0.3.0 — CJK search, RRF fusion, LLM search hooks, ontology-backed agents

Ontology search engine (Track A)

• Korean/CJK search now works. CJK bigram tokenizer + FTS5 trigram index; existing databases migrate and re-embed automatically on first open (schema v2).
• RRF hybrid ranking replaces mixed-scale fixed-weight fusion, computed over a bounded candidate pool (no full-corpus Python cosine scan).
• Host-LLM search hooks (optional, zero extra cost): query expansion and rerank callables injectable by the host CLI runtime (Claude Code / Codex). No embedding API or key required.
• Data-sovereignty gate: chunks scoped private/confidential are never passed to cloud rerank hooks — enforced inside the search pipeline and covered by a behavioral test.
• 15% chunk overlap so context is not cut at window boundaries.

Builder wiring (Track B)

• New ontology-backed-agent overlay mode: corpus-dependent requests generate retrieval-first, source-cited agents (modes/ontology-backed-agent.md).
• Rule-based governance contract injection via .agentlas/contract-injection-map.json — only the contracts matching the agent's task traits are injected (no more blanket 26-contract packages).
• Golden-path reference: examples/ontology-proposal-agent/ with a behavioral verify.sh (ingest → retrieve → draft → separate-context verify → human gate).

Architecture (Track C)

• scripts/sync-adapters.sh renders the canonical core into runtime adapter mirrors; --check is wired into verify-package.sh and blocks drift.
• loop_policy (none / self-correct / verified) derived from task risk tier; verified work uses a separate-context verifier (no self-grading).
• scripts/verify-mcp-surface.sh guards the agentlas MCP registration contract across Claude Code, Codex, Gemini, and Antigravity.
• bump-version.sh no longer hard-codes a local web path (uses AGENTLAS_WEB_INSTALL_GUIDE).

READMEs updated in en/ko/ja/zh-CN/hi. All verification gates pass: 24 unit tests, verify-package.sh, public_safety_check.sh, MCP surface check, adapter drift check, example agent behavioral verify.

v0.2.12 — Hub MCP bundled + one-touch MCP registration

The one-touch installer now registers the agentlas Hub MCP everywhere it installs the engine: Claude Code (bundled .mcp.json), Codex (rmcp client + config.toml), Gemini CLI (extension manifest), and Antigravity (mcp_config.json). No separate MCP setup step remains.

Also ships release version-sync tooling: scripts/bump-version.sh updates every pinned ref (scripts, READMEs in 5 languages, manifests, install SVGs, and the agentlas.cloud install command) in one command, and verify-install-docs.sh now fails on any stale version pin.

v0.2.11 — 2-stage security scan + Antigravity engine resolution

What's new

• 2-stage security scan (BYOK LLM judgment) — hephaestus security scan now merges static-rule findings with the user's own LLM judgment (.agentlas/security-llm-judgment.json). Combined verdict = max severity of both stages. --strict blocks BLOCK (exit 1) and now also gates WARN (exit 2) unless --acknowledge-warn.
• Antigravity /hephaestus engine resolution — the workflow now resolves the engine root from the Claude/Codex plugin cache when the workspace has no local package, so /hephaestus works in any project (previously it only looked at workspace-local files and kept saying "install first"). Also installs into both ~/.gemini/antigravity/ and ~/.gemini/antigravity-ide/ data dirs.
• Version sync — marketplace.json was stale at 0.2.9; all manifests unified to 0.2.11.

Updating

Plugin updates are pull-based (no auto-update):
```
claude plugin marketplace update agentlas-core-engine
claude plugin install hephaestus@agentlas-core-engine --force
```
or re-run the one-touch installer.

v0.2.10 — Agentlas Cloud runtime contract

What's new

• Adds the public-safe Agentlas Cloud V1 package contract with agentlas.json schema/template.
• Adds Hephaestus local CLI support for setup wizard, security scan, runtime bundle, lazy file read, and field-test.
• Bundles the Cloud runtime into Claude and Codex plugin packages.
• Updates install docs and plugin manifests to v0.2.10.

Verification

• scripts/verify-package.sh
• scripts/public_safety_check.sh
• python3 -m pytest tests/test_agentlas_cloud_runtime.py -q

v0.2.9 — Antigravity for generated agents & teams

Builds on v0.2.8 (Antigravity adapter + paste-to-install) by making Antigravity a first-class runtime in everything Hephaestus generates.

Generated packages now ship an Antigravity command

• New templates/antigravity-workflow.md.tpl; templates/global-commands.json.tpl gains an antigravity runtime entry.
• Builders and modes (agents/10|20|30, modes/*) instruct generation of an Antigravity /<command> workflow (global ~/.gemini/antigravity/global_workflows/, project .agents/workflows/) next to Claude Code, Codex, Gemini CLI, AGENTS.md, and terminal commands.
• verify-global-command-contract.sh now checks the Antigravity template wiring.

Release

• Version bump 0.2.8 → 0.2.9 across install surfaces and the paste-to-install prompts.
• All verify scripts pass (contract, install-docs, package incl. 12 ontology tests, public-safety).

Merged via #2.

v0.2.8 — Antigravity adapter + paste-to-install

First-class Google Antigravity support + a paste-to-install path for non-terminal users.

Antigravity registration & routing

• /hephaestus ships as an Antigravity workflow: antigravity/workflows/hephaestus.md (canonical) + .agents/workflows/hephaestus.md (project scope).
• scripts/install-all-runtimes.sh installs the global workflow to ~/.gemini/antigravity/global_workflows/hephaestus.md → /hephaestus in every Antigravity workspace.
• Antigravity already auto-loads AGENTS.md and .agents/skills/; this adds the missing command surface. Registry/manifest/AGENTS.md/GEMINI.md updated; antigravity is a verified runtime.

Paste-to-install (README ×5)

• New top-of-README block: one natural-language message you paste into any AI tool (Claude Code · Codex · Gemini CLI · Antigravity · Cursor) so the agent runs the installer for you.

Release

• Version bump 0.2.7 → 0.2.8. All verify scripts pass (contract, install-docs, package incl. 12 ontology tests, public-safety).

Merged via #1.

v0.2.7

• Redesigned the ontology GUI into a self-contained SaaS-style dashboard with navigation, graph, sources, query, memory queue, and command views.\n- Synced the redesigned GUI into Claude and Codex plugin bundles.\n- Bumped Claude, Codex, Gemini, installer, and README references to 0.2.7.\n- Verified package, ontology runtime, public safety, global command contract, and one-touch install smoke tests.

Hephaestus v0.2.6

What changed

• Added one-touch terminal install/update for Claude Code, Codex, and Gemini CLI.

• Added the global command contract: generated Agentlas agents/teams must emit .agentlas/global-commands.json and final global_commands handoff.
• Updated all install docs and verification to v0.2.6.
