Opportunities — the stories that would move this product's scores, from its own judged verdictsOpportunitiestop 8 of 31 stories with headroom

What would move smolagents’s scores — derived from its own judged verdicts, biggest headroom first. Each line quotes what the judge found missing; shipping it (or evidencing it publicly) is the fix.

  1. Agenticness — how well agents can access and operate the productSet up automations that run autonomously in the background

    nonemoves Built-in AIimpact 30

    The docs show agent.run(), step-by-step execution, and memory/replay for long-running tool calls, but there is no evidence of scheduling, triggers, cron-like automation, or a persistent background/daemon mode that would let an agent run autonomously without user invocation.

  2. Agenticness — how well agents can access and operate the productIssue scoped/least-privilege API credentials for an agent

    nonemoves agent-readyimpact 30

    No evidence in the pack addresses issuing scoped or least-privilege API credentials for agents; the docs cover sandboxing, authorized imports, tool creation, and multi-agent orchestration but nothing about credential scoping/least-privilege access control.

  3. Agenticness — how well agents can access and operate the productExplore an interactive API reference with runnable examples

    nonemoves API qualityimpact 30

    The docs provide static API reference pages (e.g., reference/agents parameter lists) and code snippets in guided tours, but there is no evidence of an interactive, runnable API playground (e.g., embedded live code execution, Swagger-like try-it-now UI) for smolagents specifically; the openapi.json probe hit is for the general Hugging Face platform, not smolagents' API reference.

  4. Agenticness — how well agents can access and operate the productRely on versioned APIs with a documented deprecation policy

    nonemoves API qualityimpact 30

    Missing: versioning scheme, deprecation policy documentation, changelog/migration guides.

  5. Streaming output — stories about streaming output in this arenaGet schema-validated structured output from an agent, with automatic retries when validation fails

    partialq3/10moves PA Scoreimpact 21

    Missing: explicit schema-based output validation (e.g., Pydantic/JSON schema), documented automatic retry behavior on validation failure, and any independent confirmation of this working end-to-end.

  6. Automation depth — how much of the product can run unattendedSchedule recurring jobs or workflows

    nonemoves PA Scoreimpact 20

    smolagents is a Python agent framework for building and running agent tasks; no evidence of any scheduling, cron-like, or recurring workflow trigger capability.

  7. State durability — stories about state durability in this arenaRun long-lived agents durably across process restarts and deploys, natively or via durable-execution integrations

    nonemoves PA Scoreimpact 20

    Evidence shows step-by-step execution and memory/replay features (docs-7,docs-9,docs-17,docs-21) that hint at long-running task support, but there is no documentation of state persistence across process restarts/deploys, checkpointing to durable storage, or integration with durable-execution frameworks like Temporal/Restate.

  8. Evals observability — stories about evals observability in this arenaScore agent quality with built-in evals and run them as part of CI

    nonemoves PA Scoreimpact 20

    Evidence covers agent execution, memory/replay, tracing via OpenTelemetry, and multi-agent orchestration, but there is no mention of built-in evaluation/scoring harnesses or CI integration for grading agent quality.
