mcsc SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
mcsc from hybridlabor-api/bdb-dev-optimized-agent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add hybridlabor-api/bdb-dev-optimized-agent-skills/mcsc@v0.1.0Pins v0.1.0 in mdr.lock. Pin the fingerprint instead.

Delegate a task to another installed CLI harness (Antigravity/agy, OpenCode, Codex) from inside an AOS repo. Use this instead of shelling out to that CLI directly whenever one is installed — it wraps the wrapper flags for you and streams live tool-call telemetry to agenttrail, which is why the board updates in real time. Reach for it any time you're about to delegate work to another harness.
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
# mcsc — Multi-CLI Subagent Configurator
mcsc (`mcps/mcsc/`) is AOS's own cross-harness delegation engine. It is the
mandatory path for delegating work to another CLI harness inside an
AOS-installed repo — not a Claude-Code-only convenience.
## Why this exists
Three separate, harness-specific delegation paths already exist (the Claude
Code plugins `antigravity:antigravity-delegate`, `opencode:opencode-rescue`,
`codex:codex-rescue` — see AGENTS.md's "Delegating to an external CLI"). Those
are fine for interactive delegation *from a Claude Code session*, but they are
Claude-Code-only, and none of them tell agenttrail's live board what is
happening. mcsc's adapters
(`mcps/mcsc/packages/core/src/adapters/{agy,codex,opencode}.js`) wrap each CLI
once, work from any harness, and call `emitTrail()` around every delegated run
— `SessionStart`/`SessionEnd`, plus live `PreToolUse`/`PostToolUse` where the
underlying CLI supports structured/streaming output — so a delegated run shows
up on the board the moment it starts, without any extra setup.
Skipping mcsc doesn't just lose convenience — it makes the delegated agent

How to install
mdr add hybridlabor-api/bdb-dev-optimized-agent-skills/mcsc@sha256:7147256cb05d7550The line at the top of this page pins the label v0.1.0, 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.
