forge SKILL.md skillA

forge from corvinlabs/corvinos is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add corvinlabs/corvinos/forge@v0.2.0

Pins v0.2.0 in mdr.lock. Pin the fingerprint instead.

Forge schema-bound, sandboxed tools at runtime. Paired with the cowork `forge` persona for chat-driven use in the voice-skill bridge. Use when you would otherwise write the same Bash snippet ≥3× with different parameters, when you need precise numerical results over a dataset, or when the user wants reproducible/deterministic output written to a file.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# forge — runtime tool factory for Claude Code

You (Claude) can register a new tool at runtime via the `forge` MCP server.
The new tool is callable as `mcp__forge__<name>` from the next `tools/list`
onward, in the current session and in any future session that sees the same
`~/.config/corvin-voice/forge/` workspace.

When this plugin runs inside the voice-skill repo (the normal case), the
cowork `forge` persona auto-routes user phrases like "forge mir ein tool",
"build me a tool that …", or "I need a deterministic tool" onto this MCP
server — the persona ships restrictively (no Bash/Edit/Write) so generated
tools cannot inherit the owner's bypassPermissions privilege.

## When to use forge

Reach for `forge_tool` when **at least one** of these holds:

- You would otherwise write the same Bash/Python snippet ≥3 times with
  different parameters (paths, columns, thresholds)
- You need precise numerical results over a dataset (statistics, regression,
  aggregation, filtering, splitting)
- The user wants the answer **written to a file** (CSV, JSON, PNG)
- The user uses the words *"deterministic"*, *"reproducible"*, *"save as"*,
  *"compute exactly"*, *"audit trail"*
…

How to install

The exact contents, by fingerprint

mdr add corvinlabs/corvinos/forge@sha256:d06a23fbcef2dd31

The line at the top of this page pins the label v0.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
