Build and audit a real spreadsheet from your agent host — cells, formulas, tables and charts stay editable instead of arriving as a screenshot.

Positioning

gridcraft connects an agent host to the GridCraft workbook engine, so a request ends with an editable workbook whose formulas still recalculate. The plugin owns spreadsheet skills, a same-session editor bridge and package pinning; it does not re-implement the engine, the formula evaluator or the file format.

Property	Value
Plugin ID	gridcraft
Version	0.1.0-dev.20261018.3
Status	Development preview; all-host acceptance still open
Editor runtime	Node.js 24, started from ui/bootstrap.mjs
Host requirements	Plugin or stdio MCP host; MCP Apps or a built-in browser for the panel
License	Apache-2.0

Installation

Prerequisites

• Node.js 24 on PATH; the bundled stdio MCP server runs on it.
• Network access on the first editor launch. The plugin downloads and verifies the pinned editor archive; a complete release ZIP already contains it, so no Rust toolchain, npm install or Python runtime is required.
• A host that supports plugins or stdio MCP. Embedded panels additionally require MCP Apps or a built-in browser.
• No separate spreadsheet application is needed; the workbook engine is bundled.

From the plugin marketplace

codex plugin marketplace add partme-ai/full-aigc-plugins
codex plugin add gridcraft@full-aigc-plugins

Restart the host, open a new task, and ask GridCraft to open a workbook for your workspace.

Other host manifests

Host	Manifest	Path base
Standard Agent Plugins 1.0.0	plugin.json, mcp.json	${PLUGIN_ROOT}
Codex	.codex-plugin/plugin.json, .codex-plugin/mcp.json	plugin root relative to cwd
Claude Code	.claude-plugin/plugin.json, .mcp.json	${CLAUDE_PLUGIN_ROOT}

Kimi (kimi.plugin.json), DeepSeek Harness (dsh/) and the WorkBuddy example (hosts/workbuddy/mcp.json) are also present. In a development checkout you must build the editor assets first; cloning the source is not an installed runtime.

Quick start

flowchart LR
    A[Install plugin] --> B[Restart and open a task]
    B --> C[open_editor]
    C --> D{editor_status ready?}
    D -->|No| C
    D -->|Yes| E[new_workbook]
    E --> F[set_cell / write_range]
    F --> G[evaluate_formula]
    G --> H[inspect_workbook / save_workbook]

Loading

1. Open the editor with an explicit workspace argument.
2. Create a workbook with new_workbook, or open an existing file with open_workbook.
3. Read the available commands first with list_commands, then use execute_command for anything the direct tools do not cover.
4. Write values with set_cell or write_range, and confirm calculations with evaluate_formula — never assume a formula recalculated.
5. Save with save_workbook, reopen, and check that formulas and formats survived.

MCP tools

One bundled server, gridcraft-editor, speaking stdio. The local HTTP listener only serves the editor page and its same-session bridge. The catalogue exposes 29 tools: 24 agent-callable tools and 5 _editor_* bridge tools the panel uses internally.

Family	Tools	Purpose
Session	open_editor, open_browser_editor, editor_status	Open the editor and confirm that it attached
Discovery	list_commands, list_functions	Live command IDs, parameters, and supported spreadsheet functions
Command gateway	execute_command	Run any registered engine command with JSON params
Workbook	new_workbook, open_workbook, save_workbook, inspect_workbook	Create, open, save and summarise a workbook
Cells and ranges	set_cell, get_cell, read_range, write_range	Read and write individual cells or rectangular ranges
Calculation	evaluate_formula	Evaluate a formula expression without changing any cell
Structure	create_table, sort_range, filter, format_range	Tables, ordering, filtering and cell formatting
Charts	insert_chart	Insert a chart bound to a range
Interaction	select, screenshot	Select a range; screenshot saves a window PNG (desktop app)
History	undo, redo	Step back and forward one change

Configuration

Setting	Where	Effect
workspace argument	open_editor / open_browser_editor	Binds the task folder; paths outside it are refused
CRAFT_EDITOR_UPDATE=off	stdio MCP env	Use the bundled editor only; no download attempt
CRAFT_EDITOR_CACHE_DIR	Environment	Absolute directory for verified editor archives
CRAFT_WORKSPACE_ROOT	Host MCP config	Workspace root for hosts that cannot pass it in a tool call

Verified archives are cached under ~/.cache/full-aigc/editors; an active session keeps its version until closed, and a corrupt cache falls back to the bundled build.

Architecture and security

Agent ↔ plugin traffic is stdio MCP; the browser bridge listens on 127.0.0.1 only, with a random token and Host/Origin checks. Downloads are SHA-256 verified and the bundled editor is always kept as a fallback. Skills are instructions and do not enforce policy at runtime. The plugin stores no credential and forwards no traffic to the authors.

Format behaviour and the current acceptance scope are described in editor integration and docs/verification/release-candidate.json. A workbook that opens is not proof that every formula, format or external reference survived; check after reopening.

Troubleshooting

Symptom	Action
Editor tools are missing	Confirm the plugin is enabled, restart the host, open a new task
The panel does not render inside the host	Use the URL from open_browser_editor; the terminal provides no browser panel
First open stalls	The first launch downloads the pinned archive; retry with network, or set CRAFT_EDITOR_UPDATE=off
A formula shows a stale value	Re-run evaluate_formula after the write; do not trust a cached cell
A reopened workbook lost formatting	Re-check the affected range after open_workbook and reapply the format
A write times out	Reopen or inspect the workbook before retrying; do not replay blindly

Upgrade

codex plugin marketplace upgrade full-aigc-plugins
codex plugin add gridcraft@full-aigc-plugins

The editor archive and skill digests are pinned per release; upgrading the plugin replaces the bundled runtime rather than patching it in place.

Contributing and support
