Experiment: docs-only vs skill-guided agent — compare outcomes

[tomkis]

Is your feature request related to a problem? Please describe.
Evaluating whether skills can be replaced by documentation links. It's unclear if guiding an agent via docs alone produces equivalent results to providing a structured skill — this creates uncertainty about when a skill is actually necessary.

Describe the solution you'd like
Run a controlled experiment:

1. Take an existing skill (e.g. the ADK wrapper skill)
2. Run the same prompt twice — once with the skill, once with the agent pointed only at the documentation (no skill provided)
3. Measure: does the agent find/use the docs on its own, or does it need to be directed? Are outcomes equivalent?

Describe alternatives you've considered

• Always providing a skill regardless of whether docs alone would suffice
• Relying on anecdotal observations without a structured comparison

Additional context
Result should either validate skills-as-doc-pointers or identify where structured skills add irreplaceable value.
