Install chrome-devtools-mcp as Permanent 9
Decision
Permanent MCP count expanded 8 to 9. chrome-devtools-mcp installed as stdio MCP, mirrored to /root/.claude.json, cascade across 16 canonical setup files, stitched into 4 perf-related skills as PRIMARY engine. Supersedes prior in-session decline.
Rationale
Ceiling-expansion rule satisfied on three counts. AJ explicit authorization on follow-up. Genuine uncovered gap for Lighthouse on demand and CrUX field data and memory snapshots and source-mapped stacks. Cascade executed same operation across MEMORY.md feedback_mcp_two_tier_model architecture core-platforms hooks-registry skill-usage feedback_workspace_purpose feedback_codex_workspace_parity protocols delivery-intelligence evolution-backlog AGENTS.md aj-ea CLAUDE.md and context work.md. Stitched into performance-profiler post-deploy-verification visual-regression next-js-app-audit skills. Codex side parity flagged TODO in feedback_codex_workspace_parity.
Alternatives Rejected
A on-demand npx shell out rejected because breaks autonomous flow. B decline already superseded. C wait for v1 rejected because package stable at 39k stars and weekly releases.
Outcome
