What

task_requires(steps, declared=()) in agent_env.bundle.requires: what a stored task requires, by the rule bundle register records on the tasks it writes, for a service that saves tasks without a bundle (the hub).

• The plugin packages behind the task's own step types, and behind the types of the envs and artifacts its steps read, loaded from the store, with the envs and artifacts loading them, or the agents its steps deploy, loaded (a multi env's servers, an MCP server env's or an agent's image).
• A type only configuration registers never counts, as in register.
• Ranges across saves: a package declared (what the previous version required) names keeps the range written there; one used anew is at least the installed version; one no longer used is dropped.
• When a reference can't be read here (an id the run fills in, one the store doesn't hold, a type nothing here registers), every package declared names is kept, since there's no telling whether that reference needs it.

Nothing calls it in core. The hub's sdk calls it from put_task, so every task the hub writes, edits or imports records what it needs, instead of a hub edit dropping what register recorded.

Why here

The detection (Providers, detected) already lives in bundle/requires.py; a stored-task entry point beside it keeps the hub from reading bundle internals or re-implementing the rule.

Tests

tst/unit/bundle/requires_test.py::TestStoredTasks, against fake plugin packages:

• a registered task's stored steps give exactly the requires registering it recorded (own step type; a referenced artifact type read from the store; core only gives none);
• a declared range is kept, a package used anew is >= the installed version, an unused one is dropped;
• a configuration-only step type is never required;
• a plugin image type an MCP server env or an agent holds is required, though the env's and agent's own types are core's;
• an absent, templated or unknown-type reference keeps every declared package (an unparseable declared line is still dropped).

Summary

Adds task_requires(steps, declared) to record the plugin packages a stored task needs.

• Task-saving services can derive package needs from stored steps.
