Governed ability
Update post meta
aafm/update-post-meta Guarded write
Write a single allowlisted scalar meta value to a post the agent can edit.
How it is governed
The same model as every ability in the plugin, stated for this one.
- Off until you enable it
Like every ability, Update post meta ships switched off. You turn it on one at a time, and an update never widens access on its own.
- Guarded write
Writes stay conservative, and the plugin re-checks the capability before the call runs.
- Capability gated
A connection only sees Update post meta if the user you connected can run it, and the plugin checks that capability again before it executes.
- Every call audited
The call is written to the log in your own database, denials included, with the argument keys but never the values.

Try it with a prompt
Example requests you could paste to your agent.
Set the subtitle meta on post 142 to A Practical Guide.
Update the read_time custom field to 8 on that tutorial post.
Change the cta_label meta value on the pricing page to Start free.
These are illustrative example prompts. The agent runs them as the user you connected, checked against that user's capabilities and written to your audit log.
