Project updates and deletion previously persisted every loaded chat, while matching chats were written twice through the existing activation helpers.
Keep the established project lifecycle flow and remove the unconditional writes so only affected chats are saved once. Add focused regression coverage and document the persistence contract.
Validate destructive requests and project-derived scopes at the Agent Editor API boundary, and reuse the running-profile guard for deletion.
Recheck creation and availability invariants inside the existing mutation boundary, preserve project availability atomically through its dedicated owner, and keep Project Edit and Settings catalogs from replaying stale or unavailable profile state.
Add focused regressions for confirmation, collisions, malformed project metadata, avatar failures, running profiles, and sparse project updates.
Add per-scope availability, duplication, active-profile status, and inline project selection while keeping the profile switcher synchronized with runtime state.
Reconcile unavailable profiles at explicit disable, deletion, project-transition, and context-creation boundaries; polish validation, prompt layout, deletion, and completion states; and extend focused backend and WebUI coverage.
Load active-project AGENTS.md path-chain guidance into the protocol area without duplicating the project root instructions.
Move the AGENTS.md protocol wording into a prompt template, reuse existing file/path helpers, and cover direct-path discovery plus prompt assembly with focused tests.
Create the .a0proj/skills directory during project metadata setup so Project Settings can open the skills folder for new projects. Repair the folder when loading existing project settings, and cover both creation and repair with regression tests.
Add project-scoped MCP server configuration with global/project merge semantics, a richer settings UI, and chat composer access. Introduce MCP config scanning plus project-aware status/detail/log/apply APIs while preserving the raw JSON editor. Strengthen MCP runtime handling for dotted tool names, timeouts, status accuracy, and project-aware tool execution, with focused regression coverage.
Add support for including a top-level AGENTS.md in a project's system instructions while keeping backwards-compatible defaults. Introduces include_agents_md project metadata (defaults to true), normalization and save logic, and helper functions to discover and format AGENTS.md and other instruction files into the system prompt. Updates build_system_prompt_vars to assemble instruction parts, adds UI checkbox in project edit form, normalizes defaults in the projects store, and adds tests for the new behavior. Also documents the compatibility rule in AGENTS.md and adds a small prompt rule reminder.
