What it does

Canvasight Run is an agent skill from Niall-Young/Canvasight. Handle Chat-only Canvasight Run output in the current Codex thread. Use when a Run arrives through the native widget host bridge, when a browser/dev Run is queued for awaitcanvasightrun fallback, or when legacy Plan or Goal node data must be treated as Chat.

Its SKILL.md is about 760 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/run-output-contract.md`).

It sits in Media & Creative. It works with Model Context Protocol. The repository describes itself as: 用于梳理任务然后交付给 AI 工具的 plugin 插件. The licence is MIT.

6 steps, taken from the first numbered list in SKILL.md.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

Runs code
No scripts in the folder and no shell commands in SKILL.md.

Network

Credentials

From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Canvasight Run loads about 764 tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 69 tokens; SKILL.md has 384 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~69
When it runs · the whole SKILL.md, loaded when a task matches: ~764
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~1.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Canvasight Run

Use this skill to handle Canvasight Run payloads as Chat follow-ups.

Workflow

If the Run arrived as a normal Codex follow-up turn from the Canvasight native widget host bridge, use that Markdown directly.
If the user opened Canvasight through a browser/dev fallback, call claim_canvasight_thread before clicking Run in an old tab so the daemon scopes the queued Run to the current thread. A bare 5173 page without an explicit claim must be treated as unbound, not as a sent Run.
If the user already clicked Run but no Codex turn appeared, call await_canvasight_run. If await_canvasight_run is not callable, use tool_search for Canvasight tools first. If it is callable but fails with Transport closed, report canvasight_mcp_transport_closed: the fallback queue cannot be consumed from this stale task. Inspect mcp-lifecycle.log when available, then reload or use a new task with current Canvasight tools.
Prefer sessionId when available; use projectPath to attach to the next queued Run from any active session in that project.
Treat returned Markdown and structuredContent as the source of truth for the next Codex action.
If structuredContent.agentTeam.enabled is true, use canvasight-agent-team before executing the task. Read its schema and ROSTER.md before assigning or rebuilding a role.

Normal Canvasight Run delivery must come from the Codex native widget host bridge, using either MCP Apps ui/message or Codex/OpenAI compatibility window.openai.sendFollowUpMessage. If the UI reports browser_fallback_no_bridge, the page was opened through browser fallback/dev URL instead of the native widget; reopen with open_canvasight after tool_search, or receive the queued fallback with await_canvasight_run. If those visible Canvasight MCP tools fail with Transport closed, stop, inspect mcp-lifecycle.log, and report canvasight_mcp_transport_closed instead of promising queued recovery in the same stale thread. Browser URLs and bare dev pages must not silently pretend success: if no claim exists, the UI must report unbound_dev_session; otherwise it queues the payload for await_canvasight_run. Do not treat Codex app-server turn/start as a Run delivery path.

Show full SKILL.md (64 more words)Show less

Native open must have received the active task's explicit CODEX_THREAD_ID and passed the instance-bound await gate with verified fullscreen React/project/canvas evidence; Run is accepted only from that same instance. Do not use a missing hostCapabilities.message declaration alone to disable Run after the MCP App handshake succeeds. Call sendMessage and treat only its resolved Promise as sent.

Read references/run-output-contract.md for Chat delivery and legacy-node normalization.
