async-render-example SKILL.md skillA
async-render-example from dcc-mcp/dcc-mcp-core is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add dcc-mcp/dcc-mcp-core/async-render-example@git:20260927.f5cfb64Pins git:20260927.f5cfb64 in mdr.lock. Pin the fingerprint instead.

Example skill — demonstrates async execution affinity: long-running tools surface as deferredHint=true in MCP tools/list. Use as a reference when writing domain skills with render or simulation tools. Not intended for production use.
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
# Async Render Example (issue #317)
This skill demonstrates the `execution` and `timeout_hint_secs` fields added
for issue #317. Tools are declared with either `execution: sync` (default)
or `execution: async`; the MCP server derives the `deferredHint` annotation
from this value and surfaces `timeout_hint_secs` under
`_meta.dcc.timeoutHintSecs` on the tool definition (never inside
`annotations`).
## Behaviour
- `render_frames` → `execution: async` + `timeout_hint_secs: 600`
→ `tools/list` entry gets `"annotations": { "deferredHint": true, ... }`
and `"_meta": { "dcc": { "timeoutHintSecs": 600 } }`.
- `quick_status` → no `execution` field → default `Sync`
→ `"annotations": { "deferredHint": false, ... }` and no `_meta`.
## Script convention
Each script reads JSON parameters from stdin and writes a JSON result to
stdout — the standard dcc-mcp-core skill script contract.Read the whole file at its exact version.
How to install
mdr add dcc-mcp/dcc-mcp-core/async-render-example@sha256:afe9c9fc70392d63The line at the top of this page pins the label git:20260927.f5cfb64, 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.
