activity skillA
activity is agent-read markdown (skill) from mubit-ai/plugins: List or export what this instance holds for a run; use when the user wants the audit record, not an answer..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
**This skill never installs anything, and it writes nothing anywhere unless asked.** It runs one
Node process from the plugin directory, makes one or more read-only calls to the configured
instance, and prints the answer.
**Do not run it on your own initiative.** This is a question a person asks about their own data;
nothing in a conversation should decide by itself to pull a copy of somebody's memory into the
transcript. The Claude Code copy of this skill enforces that with
`disable-model-invocation: true`, a key Codex does not read — so under this host the rule is
this paragraph, and it is on you to keep it.
## Step 0 — resolve the binary
No environment variable carries this plugin's path under Codex. Codex lists each skill with the
absolute path of its `SKILL.md`; **this file** is at `<plugin-root>/skills/activity/SKILL.md`,
so the binary is two directories above it:
```
<plugin-root>/bin/activity.mjs
```
Resolve that to an absolute path from this file's own location and use it in every command
below. Do not write `${CLAUDE_PLUGIN_ROOT}`: Codex sets no plugin-root variable of any spelling,
so the shell expands it to nothing and `node /bin/activity.mjs` fails with ENOENT.
…Read the whole file at its exact version.
How to install
mdr add mubit-ai/plugins/activity@git:20260903.008c305mdr add mubit-ai/plugins/activity@sha256:7258935eff7a7558Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
