Previous fallback was too soft: "discover intent, pick the best tool, confirm assumptions" was interpreted by Codex as "search the local workspace for kb:// material" — which never exists locally and burns context on fruitless exploration. New fallback makes the recovery path explicit: - STOP on Auth required / server unreachable - surface the exact fix command (`codex mcp login oci-deal-accelerator`) to the user - never reconstruct the KB from local files (server-side only) - never invent SKUs, pricing, or service quantities - never generate partial artifacts with inferred data Scoped: applies only when the entire MCP session is unreachable. Per-tool failures still follow the methodology's guidance. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
OCI Deal Accelerator — Codex Plugin
Codex plugin that connects to the OCI Deal Accelerator MCP server and bundles a companion skill. Distributed internally via ai-lad.com.
What you get
14 tools surfaced through a remote MCP server (streamable HTTP, OAuth 2.1):
generate_full_proposal,generate_bom,generate_bom_appca,generate_cost_estimategenerate_deck,generate_diagram,generate_business_caserun_wa_review,check_feature_compatibility,compare_competitivesearch_reference_architectures,search_field_findings,report_field_findingscore_ecal_readiness
Plus a skill (skills/oci-deal-accelerator/SKILL.md) that guides Codex on when and how to invoke each tool.
Install
Once the plugin is registered in ai-lad.com you will get an <ID>. Replace it below.
Windows (PowerShell)
iwr -UseBasicParsing 'https://ai-lad.com/api/skills/<ID>/install-script?os=windows' | iex
macOS / Linux
curl -fsSL 'https://ai-lad.com/api/skills/<ID>/install-script?os=unix' | bash
The installer downloads the plugin ZIP, extracts it to ~/plugins/oci-deal-accelerator/, merges the ai-factory marketplace entry in ~/.agents/plugins/marketplace.json, and restarts Codex. Policy: installation: "AVAILABLE", authentication: "ON_INSTALL".
First-run authentication
On first install Codex kicks off the OAuth 2.1 + PKCE flow against the MCP server (AS proxy → OCI Identity Domain). A browser window opens; sign in with your Oracle SSO.
The MCP server implements Dynamic Client Registration (RFC 7591), so Codex's ephemeral http://localhost:<port> callback registers itself on the fly — no manual whitelisting in the AS required. Restricted to @oracle.com identities.
Re-authentication
If a tool call fails with Auth required, the OAuth access token has expired and Codex did not refresh it automatically. Re-authenticate without uninstalling:
codex mcp login oci-deal-accelerator
Opens the browser, re-authenticates with Oracle SSO, tools are available again. If that fails, force a clean slate first:
codex mcp logout oci-deal-accelerator
codex mcp login oci-deal-accelerator
As a last resort, uninstall the plugin from /plugins and reinstall — the authentication: "ON_INSTALL" policy triggers a fresh OAuth flow on install.
