Agent Persona Exploration - 2026-03-03

[github-actions[bot]]

Systematic test of the agentic-workflows custom agent across 5 software worker personas and 8 representative automation scenarios. The agent was evaluated on trigger selection, tool recommendations, security practices, and prompt clarity.

Persona Overview

• Agent: agentic-workflows (dispatcher → create-agentic-workflow.md)
• Personas Tested: Backend Engineer, Frontend Developer, DevOps Engineer, QA Tester, Product Manager
• Scenarios Tested: 8 (2 per persona except DevOps: 2)
• Average Quality Score: 3.9 / 5.0

Key Findings

1. Scheduled + read-only tasks score highest — PM1 (weekly digest) scored 5/5: fuzzy scheduling, GitHub MCP, create-issue with close-older-issues is the cleanest fit for the model
2. PR automation (4/5 average) — BE1, FE1, FE2, QA1 all handled well; single-job constraint is the main friction point for workflows needing two-pass comparisons (base vs head)
3. External API integration scores lowest (3/5) — BE2 and DV2 expose gaps around web-fetch auth and multi-provider secret management
4. Security practices are consistently applied — Minimal permissions, safe-outputs for writes, fuzzy scheduling, and network restrictions were correctly recommended across all scenarios
5. Critical footgun present in BE2: Copilot engine cannot access api.github.com directly — GitHub MCP is mandatory, not optional, but easy to misconfigure

Top Patterns Observed

1. Most common trigger: pull_request with paths: filter (4/8 scenarios)
2. Most recommended tools: GitHub MCP (toolsets: [default] or specific sets), bash for data processing, playwright for visual tasks
3. Security consistent: safe-outputs used for all writes, permissions: scoped minimally, network: explicit in API scenarios

High Quality Responses (Scores 4–5)

PM1 — Weekly Feature Digest (5/5)

• Trigger: schedule: weekly (fuzzy — auto-scatter by compiler)
• Tools: GitHub MCP [pull_requests, issues, search]
• Safe-outputs: create-issue + close-older-issues: true + expires: 30
• No network required; title includes ISO week for deduplication
• Perfect fit: read-only + structured output + recurring report pattern

FE1 — Visual Regression on Components (4/5)

• Trigger: pull_request (paths: src/components/**)
• Tools: playwright + cache-memory (baseline screenshots per branch)
• Referenced visual-regression.md guide automatically
• Correctly flagged: cache-memory filenames must use YYYY-MM-DD-HH-MM-SS (no colons)

DV1 — Post-Mortem Incident Issues (4/5)

• Trigger: workflow_run filtered to failed deployments
• Tools: GitHub MCP [actions, repos] to fetch run logs
• Added log pre-filtering step (bash) before agent invocation to avoid context overflow
• Safe-outputs: create-issue with title-prefix: "[incident] " + expires: 7d

QA1 — Test Coverage PR Analysis (4/5)

• Referenced test-coverage.md guide
• Inferred runtime from repo language files (go.mod → Go, package.json → Node)
• Flagged coverage format variance (LCOV vs Cobertura vs cover.out) as explicit prompt concern

Areas for Improvement (Scores 3)

BE2 — Webhook Error Triage (3/5)

• Trigger: repository_dispatch is correct but agent didn't proactively warn about Sentry webhook format mismatch
• Critical issue: Instructions don't emphasize strongly enough that Copilot engine cannot access api.github.com — GitHub MCP is non-negotiable for issue creation
• Stack trace size limit (64KB) for client_payload not surfaced proactively
• Duplicate deduplication logic left ambiguous ("search by error fingerprint" without specifying what fingerprint means)

DV2 — Cloud Cost Anomaly Digest (3/5)

• web-fetch tool has no built-in auth header support — multi-cloud billing APIs all require OAuth/API keys
• Agent correctly suggested bash+curl workaround but this adds significant prompt complexity
• Multi-provider API schema differences not addressed; agent response assumed single-cloud
• No guidance on secret naming conventions for cloud credentials
• Historical baseline via cache-memory correctly suggested but filename safety reminder omitted

Recommendations

1. Strengthen GitHub MCP requirement guidance — Add an explicit callout in the create-agentic-workflow.md prompt: when the Copilot engine is used, GitHub MCP is required for any GitHub API interaction (not optional). The current framing is too subtle and leads to silent failures.

2. Add web-fetch auth pattern to the prompt — The agent needs a standardized pattern for authenticated API calls (bash+curl with $\{\{ secrets.X }} injection) since web-fetch is unauthenticated. A short "When external APIs require auth" section with a template would prevent DV2-style friction.

3. Make cache-memory filename safety more prominent — The colons-in-filenames footgun (NTFS artifact limitation) was caught for FE1 but not DV2. This should be a default reminder whenever cache-memory is configured for time-stamped data.
