Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (12)

`flipletters_example_board`read-only	Returns a complete, valid flipcode document for a board type (minimal, trainboard/station, artboard, flipdot, marquee, announcement, arena) — a known-good starting point to edit rather than writing from scratch.
`flipletters_flipcode_reference`read-only	Returns the flipcode cheat sheet (spec v1): directives, board types and size limits, transition modes, and flip-native effect recipes. Call this before writing a board so the code you produce is valid on the first try.
`flipletters_list_postiz_destinations`read-only	Lists Postiz destinations (masked keys) attached to a FlipLetters project. Use flipletters_list_workspaces first. Requires Authorization: Bearer flk_….
`flipletters_list_postiz_integrations`read-only	Lists connected social channels for a project's Postiz share account. Use before flipletters_share_to_postiz to get integrationId. Requires Authorization: Bearer flk_….
`flipletters_list_teams`read-only	Lists FlipLetters teams the API key owner belongs to (teamId, name, inviteCode). Requires Authorization: Bearer flk_… with team scope.
`flipletters_list_workspaces`read-only	Lists agency projects (workspaces) for the API key owner, plus the active project id. Project-scoped keys return their bound project as active. Requires Authorization: Bearer flk_….
`flipletters_render_board`	Parses flipcode and submits a cloud MP4 render under the API key owner's FlipLetters plan (same free quota / Premium / Studio limits as the Studio). Requires Authorization: Bearer flk_… (or FLIPLETTERS_API_KEY on stdio). Polls until done (or returns jobId if wait=false). Prefer share links for free previews; only render when the human wants an MP4 file.
`flipletters_render_status`read-only	Poll a cloud render job started with flipletters_render_board. Requires Authorization: Bearer flk_….
`flipletters_share_to_postiz`	Uploads a cloud media URL (or Studio host local fileName) to a project's Postiz destination and schedules/drafts/posts it. Loop: render_board → list_workspaces → list_postiz_destinations → list_postiz_integrations → share_to_postiz. Requires Authorization: Bearer flk_…. Prefer mediaUrl from flipletters_render_board.
`flipletters_share_to_team`	Parses flipcode and shares the board into a Team Library the key owner is a member of. Requires Authorization: Bearer flk_…. Use flipletters_list_teams first to get teamId.
`flipletters_template_url`read-only	Builds a human-readable FlipLetters Studio URL where every query parameter mirrors one flipcode line — good for short text boards you want legible in the address itself (chat messages, docs). For full fidelity or paint grids use flipletters_validate_board's share link instead. Slides are strings with \| between rows.
`flipletters_validate_board`read-only	Parses a flipcode document, returning the normalized canonical code, any warnings (out-of-range values are clamped, unknown lines ignored), a board summary, and links: a share URL that opens the exact board in the FlipLetters Studio, and an open-with-code URL that also reveals the code panel. Use this after drafting a board; fix warnings and re-validate until clean, then give the human the share link.
