PraisonAI adds enforced capability gates for Agent Skills

The PR introduces a capability-gate flow for Agent Skills: skills can declare required capabilities via frontmatter, and a new validator enforces those requirements through SkillManager and discovery so unusable skills can be filtered or blocked before execution.

What is Different

Before

Scattered source updates, isolated context, and manual follow-up across multiple feeds.

Now

Added a SkillRequirements model to declare skill dependency constraints, a CapabilityValidator with enforce levels (disabled, telemetry, warn, strict), and integration into the existing discovery/SkillManager path so agent flows can evaluate skill readiness consistently; also added CLI diagnostics to surface missing dependencies and migration/backward-compatible handling.

Why Track This

Why It Matters

Operators and AI workflow builders can catch missing skill prerequisites before a run starts, so agents are less likely to hit unexpected mid-execution failures when a required external dependency is absent. The change also exposes a clear diagnostic path via the doctor command and enforcement modes, which should reduce troubleshooting time for flaky skill setups. After rollout, watch for migration gaps in existing skills without the new requires_* metadata, false positives/negatives in dependency detection, and policy configuration errors in SKILL_CAPABILITY_ENFORCEMENT (especially when switching to strict mode).

What To Watch Next

  • Watch whether PraisonAI Agent Skills becomes a repeated pattern.
  • Track follow-up changes around AI Agents.
  • Compare future signals against this evidence trail.
  • Re-check risk flags: missing_required_metadata_on_existing_skills, false_positive_dependency_checks.
