- Upgrade @cyanheads/mcp-ts-core ^0.8.19 → ^0.9.1
- Add server-level `instructions` paragraph via createApp() (framework #91): tool prefix, ID conventions (H/S/P, C), cycle semantics
- Fix devcheck `bun outdated` parser — markdown rows start with leading `|`, so split index [0] was empty and silently bypassed the allowlist; now reads index [1] and strips `(dev|peer|prod|optional)` workspace markers
- Raise build-changelog SUMMARY_MAX_LENGTH 250 → 350
- DevDeps: @biomejs/biome ^2.4.14 → ^2.4.15, @types/node ^25.6.2 → ^25.8.0, vitest ^4.1.5 → ^4.1.6
- Sync skills against framework 0.9.x: api-linter (5 portability rules), api-auth (mcp_tool_scopes + OIDC operator setup + MCP_AUTH_DISABLE_SCOPE_CHECKS), add-tool (mutator response design + unit-bearing field names), tool-defs-analysis
- CLAUDE.md: portability guidance, literal-union exemption note, sparse-payload checklist items
- README.md: drop stale dev:stdio/dev:http references, align Bun prereq with engines (≥1.3.0), OTEL row links to framework telemetry docs
