Per-agent trigger filtering no longer +leaks across agents sharing a `setup_id`: the SDK tool cache stops +trimming `ToolModuleInfo.tools` by per-selection triggers; the full +catalogue is always stored, and per-agent filtering happens at the +consumer site. + +The cache contract changes shape (full catalogue per `setup_id` instead of +trimmed lists) but the public API is unchanged. Persisted `resolved_tools` +written by `<= 0.4.3` may still hold incorrectly trimmed lists — they are +automatically flushed by the startup clear introduced in 0.4.3, but the +first mission run after upgrading may want a setup-version bump to be +absolutely safe. See the **Migration** section below. + +## Bug — capability leak across agents (DEV-631) + +### Symptom + +In archetype-isaac, a single setup can host a `main_agent`, a `team` with +`N` members and a `workflow` with `M` steps. Each agent independently +selects which trigger protocols of a shared SDK tool (one `setup_id`) it +can call, via a `tools` field carrying a list of +`ToolSelection({setup_id, triggers: {name: bool}})`. + +When several agents reference the same `setup_id` with different trigger +booleans, the **first** agent walked by the SDK silently dictated which +tools were loaded for **every** other agent. Example with three agents +sharing one `setup_id` (a Knowledge Graph tool with 5 triggers): + +| Agent | Configured triggers | Effective tools (before fix) | +|----------------------|-------------------------------------|------------------------------| +| `main_agent` | all 5 true | all 5 | +| member "search only" | `{search: true, rest: false}` | all 5 | +| member "edit only" | `{edit: true, rest: false}` | all 5 | + +…and worse, if `main_agent` had `edit: false`, the "edit only" member would +**lose access to `edit` entirely** — its own trigger config was ignored. + +### Root cause + +`ToolReference._resolve_single` previously trimmed the resolved +`ToolModuleInfo.tools` in place, based on a **single** `ToolSelection`'s +triggers: + +```python +if enabled_triggers := {name for name, enabled in entry.triggers.items() if enabled}: + tool_info.tools = [t for t in tool_info.tools if t.name in enabled_triggers] +``` + +`SetupModel._collect_from_tool_ref` keys the resolution cache by `setup_id` +only and short-circuits via `has_uncached`. Subsequent `ToolReference` +instances pointing at the same `setup_id` therefore skipped resolution and +reused the first writer's trimmed object. The trimmed `ToolModuleInfo` then +populated `context.tool_cache.entries`, which downstream toolkit code +(e.g. archetype-isaac's `ModuleToolkit`) reads from. Per-agent +`allowed_tools` filters could only shrink that already-trimmed list, +never re-expand it — so any trigger the first resolver dropped became +permanently invisible to later agents. + +`resolved_tools` is also persisted across mission runs (invalidated only on +setup-version bumps prior to 0.4.3, or on module startup since 0.4.3), so a +stale trimmed cache survived runs until the user edited the setup or +restarted the module. + +### Fix + +`ToolReference._resolve_single` no longer touches `tool_info.tools`. It +returns the full module catalog, unchanged. The full canonical +`ToolModuleInfo` is stored under `tool_cache.entries[setup_id]` and +re-used by every agent that references the setup. + +Per-agent filtering is the consumer's responsibility — for example +archetype-isaac builds one `ModuleToolkit(allowed_tools=...)` per agent +with `allowed_tools` derived from that agent's own `ToolSelection.triggers`. +Filtering after the cache, on each toolkit instance, means three agents +on the same `setup_id` with `{search: true}`, `{edit: true}` and +`{everything: true}` each end up with exactly the tools they declared, +even though the underlying cache entry holds the full catalog. + +### Architecture (after fix) + +``` +ToolReference.resolve + └─ _resolve_single(entry) # no triggers filter + └─ registry.discover_by_id # returns full ModuleInfo + └─ module_info_to_tool_module_info → ToolModuleInfo (full tools) + └─ tool_cache.entries[setup_id] = info # shared, untrimmed + +Consumer (e.g. archetype-isaac) + └─ ToolkitMixin.create_toolkit_for_selection(setup_id, triggers) + ├─ allowed_tools = {name for name, enabled in triggers.items() if enabled} + └─ ModuleToolkit(tool_module_info, allowed_tools=allowed_tools) + └─ filters Function objects per agent, never mutates the cache +``` + +## Migration + +- **No code changes required** in consumers.
