description	Spawn the doey-scaffy MCP server so workers can drive the Scaffy template engine via tool calls. Loaded automatically when a task needs scaffy_run / scaffy_validate / scaffy_list / scaffy_audit / scaffy_discover / scaffy_new / scaffy_fmt or any scaffy:// resource.

Doey Scaffy MCP Skill

When this skill is loaded, Doey's skill-embedded MCP lifecycle (task #499) parses the mcp_servers block above, generates a per-pane .mcp.json config in $DOEY_RUNTIME/mcp/, and launches the Claude instance with --mcp-config <path>. The doey-scaffy binary is spawned as a stdio MCP server for the duration of the worker's session.

Usage

Load this skill from any worker that needs to run, validate, list, or generate .scaffy templates. The MCP tools below appear in the worker's tool palette as mcp__doey-scaffy__<tool-name> and the resources as mcp__doey-scaffy__<resource-uri>.

No manual setup is required — the skill spawns the server, and Doey's team-despawn cleanup tears down the MCP process and config when the team is killed.

Tools

• scaffy_run — Apply a .scaffy template to the working tree (the 7-stage execution pipeline).
• scaffy_validate — Parse a template and (optionally) run strict validation checks.
• scaffy_list — List the templates available in .doey/scaffy/templates/.
• scaffy_audit — Report which templates are stale, broken, or missing canonical formatting.
• scaffy_discover — Mine the working tree and git history for scaffolding patterns: structural directory shapes, accretion (injection) files, and refactoring co-creation pairs.
• scaffy_new — Scaffold a new template stub, optionally seeded from existing files.
• scaffy_fmt — Format a template to canonical form (idempotent Parse + Serialize).

Resources

• scaffy://registry — The .doey/scaffy/REGISTRY.md catalog, served as text/markdown.
• scaffy://audit — JSON report of registry health (stale, broken, drift).
• scaffy://template/{name} — The raw .scaffy source of a single template.
• scaffy://templates — A JSON array of RegistryEntry objects (one per discoverable template).

Notes

• The doey-scaffy binary must be installed at ~/.local/bin/doey-scaffy. It is built from tui/cmd/scaffy/ by _build_all_go_binaries in shell/doey-go-helpers.sh and installed alongside the rest of Doey's Go binaries. If the binary is missing, run doey reinstall (or doey doctor to confirm) before loading this skill.
• MCP servers start at Claude launch — they cannot be added or removed at runtime, so this skill must be present in the worker's loaded skill set when the pane is spawned.
• Each team gets an independent doey-scaffy MCP process; there is no cross-team sharing of in-memory registry state.
