external-solver-discovery SKILL.md skillA
external-solver-discovery from svd-ai-lab/sim-cli is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add svd-ai-lab/sim-cli/external-solver-discovery@git:20261019.3a59f1dPins git:20261019.3a59f1d in mdr.lock. Pin the fingerprint instead.

Discover and safely use external ad hoc solver capabilities, third-party skills, plugins, MCP servers, or native APIs when the host app or agent environment does not bundle a first-party solver path. Use for unsupported solver requests such as FDTD, Lumerical, Meep, openEMS, Tidy3D, gprMax, CST Studio Suite, or user-provided external integrations.
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
# External Solver Discovery
Use this skill when a user needs a solver, third-party plugin, MCP server,
native API, or cloud service that is not already covered by a bundled
solver-specific skill.
This skill is an ad hoc discovery layer. It does not make an external solver
supported, installed, licensed, authenticated, or available. It helps the agent
find credible local or user-configured routes and report evidence honestly.
## Required Protocol
1. Name the requested capability and distinguish it from bundled solver support.
For example, HFSS support is 3D EM support, not FDTD support.
2. Check the current runtime before network-dependent discovery:
- attached files and workspace extensions
- project package files and scripts
- installed commands, environment variables, registry/app paths, and common
application locations
- visible skills, plugins, MCP tools, connector tools, and native APIs
- user-provided licenses, paths, profiles, or account hints
3. If a third-party skill, plugin, or MCP server is visible, inspect its own
manifest, README, SKILL file, tool schema, or help output before using it.

How to install
mdr add svd-ai-lab/sim-cli/external-solver-discovery@sha256:46891bcffac6d1beThe line at the top of this page pins the label git:20261019.3a59f1d, 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.
