Released: 2026-05-21 Chart: oci://ghcr.io/cnoe-io/charts/ai-platform-engineering:0.4.16 Previous release: 0.4.15

Highlights​

0.4.16 is a maintenance release focused on correctness. The RAG_MAX_OUTPUT_CHARS cap now actually fires for MCP tool results (previously a type check silently skipped truncation), seed agent configs once again persist their ui, features, and interrupt_on fields to MongoDB, and two reopened CodeQL code-scanning alerts are closed. The bundled CAIPE API reference docs were also refreshed to match the current BFF and RAG surfaces.

What's New​

Documentation​

  • Refreshed CAIPE API reference — replaced the stale /api/usecases and UI OpenAPI examples with a current BFF reference (auth, chat/runtime proxies, dynamic agent config, MCP server config, workflows, skills/catalog, RAG proxy, settings/users, admin routes) plus a dedicated Knowledge Bases RAG API reference (#1484)

Bug Fixes​

  • rag: _truncate_output now serializes non-str results with json.dumps before applying the length cap — MCP tools return list[dict] content blocks, so the previous isinstance(result, str) guard was always False and RAG_MAX_OUTPUT_CHARS truncation never fired (#1488)
  • ui: persist ui, features, and interrupt_on fields in seedAgents — agent gradient themes, middleware config, and human-approval (interrupt) settings were silently dropped when upserting seed agents to MongoDB; the same change also refines the escalation-handoff and clear-role-definition micro-prompts and removes the no-second-person-preamble AI review rule (#1486)

Security​

  • code scanning: closed two CodeQL alerts that reopened on main — removed a clear-text logging path derived from client_secret state in get_token.py, stopped copying raw exception text into the skill scanner result dict in skill_scanner_runner.py, and restored the filesystem Grype SARIF category from grype-filesystem back to the historical grype category so older alerts are correctly superseded (#1478)
