Actionable Opportunities

[multi-agent] — Prefer Flat Sub-Agent Fan-Out for Maximum Yield

Paper: Decomposition Buys Integrity, Not Yield
Authors: Rong He
Published: 2026-09-15
Effort: medium
Rationale: The paper shows retention scales as C^k N^(1-δ), so each added hierarchy level compounds information loss while flat trees maximize yield; gh-aw's sub-agent fan-out orchestration should therefore prefer wide, shallow agent trees and warn or discourage deep nesting when configuring sub-agents for research/summarization tasks.

[multi-agent] — Mediated Social-Harness Validation for Inter-Agent Messages

Paper: Agentic Societies Need a Social Harness
Authors: Tapan Chugh, Vidushi Singh, Krish Jain
Published: 2026-09-15
Effort: medium
Rationale: The paper's layered social harness mediates and validates inter-agent messages to block manipulation before it reaches an agent's personal context; applied to gh-aw's sub-agent fan-out, this would add a validation/format-enforcement step on messages passed from sub-agents back to the orchestrator, reducing risk of malicious or faulty sub-agent outputs corrupting the orchestrator's trust boundary.

[multi-agent] — Prefer Single-Model-Family Sub-Agent Ensembles Over Diverse Pools

Paper: Mo' Models, Mo' Problems: How to best select model pools when designing Multi-Agent Systems
Authors: Sara Vera Marjanović, Jiacheng Xu, Aleksandr Laptev
Published: 2026-09-15
Effort: low
Rationale: The paper shows that expanding candidate model pools with diverse models often degrades majority-voting/judging accuracy versus the top single model, and that same-family selection performs best; gh-aw's sub-agent fan-out and model alias configuration should encode this as guidance/defaults to avoid users blindly adding more diverse engines expecting gains.

• Investigate: Prefer flat sub-agent fan-out for maximum yield (effort: medium)
• Investigate: Mediated social-harness validation for inter-agent messages (effort: medium)

Quick-Win Agentic Prompts

Paste one of these as a new issue or comment to kick off implementation with @copilot
(one prompt per opportunity, in the same order as above):

@copilot Implement: Default sub-agent fan-out to a flat (single-level) topology instead of deep nested hierarchies when the goal is maximizing findings retained, reserving multi-level trees only when result integrity/organization outweighs recall. in gh-aw's multi-agent component. Rationale: The paper shows retention scales as C^k N^(1-δ), so each added hierarchy level compounds information loss while flat trees maximize yield; gh-aw's sub-agent fan-out orchestration should therefore prefer wide, shallow agent trees and warn or discourage deep nesting when configuring sub-agents for research/summarization tasks. Source: Decomposition Buys Integrity, Not Yield.

@copilot Implement: Add a mediated social-harness validation layer between sub-agents and the orchestrator that sanitizes/validates inter-agent messages before they enter any agent's context, detecting manipulation/prompt-injection attempts from untrusted sub-agent outputs. in gh-aw's multi-agent component. Rationale: The paper's layered social harness mediates and validates inter-agent messages to block manipulation before it reaches an agent's personal context; applied to gh-aw's sub-agent fan-out, this would add a validation/format-enforcement step on messages passed from sub-agents back to the orchestrator, reducing risk of malicious or faulty sub-agent outputs corrupting the orchestrator's trust boundary. Source: Agentic Societies Need a Social Harness.

@copilot Implement: For sub-agent fan-out with model aliases (small/large), default to drawing all sub-agents from a single model family/provider rather than mixing diverse engines, and cap ensemble size instead of maximizing model diversity. in gh-aw's multi-agent component. Rationale: The paper shows that expanding candidate model pools with diverse models often degrades majority-voting/judging accuracy versus the top single model, and that same-family selection performs best; gh-aw's sub-agent fan-out and model alias configuration should encode this as guidance/defaults to avoid users blindly adding more diverse engines expecting gains.
