annotations

When to use

Pick this skill any time the task is a mutation: adding/editing/ removing a comment, renaming a function, deleting a flag, persisting session state. For read-only annotation lookups, use data or disassembly.

Required: write mode + project

Mutations only land in r2's session memory. To persist them across reopens, save a project with radare2's own Ps before exiting, and reopen with -p. Both are r2 commands, not SQL -- lifecycle is radare2's job.
