Execution Instructions

Step 1: Extract Factual Information

Review all input sources and create a fact list:

From GitHub Profile:

• Full name (use name field)
• Current role (from bio field)
• Location (exact string from location field)
• Company affiliation (from company field)
• Social media links (from blog, twitter_username)
• Organization memberships (from organizations array)

From Video Descriptions:

• Job titles mentioned
• Company/organization affiliations
• Role descriptions
• Achievements or credentials

From Transcript Excerpts:

• Self-described roles
• Work responsibilities
• Project involvement
• Team or organizational context

Critical Rule: Only extract information explicitly stated in sources. Do NOT infer, guess, or extrapolate.

Step 2: Resolve Conflicts

If sources provide conflicting information:

1. Prioritize GitHub profile for current role and location (most up-to-date)
2. Use most recent video for role descriptions (check dates)
3. Cross-reference multiple sources for consistency
4. When uncertain: Use the most conservative claim

Example Conflict:

• GitHub bio: "Kubernetes Advocate at CNCF"
• Video description (2024): "Senior Developer at Company X"
• Transcript (2025): "I work at CNCF on Kubernetes"

Resolution: Use "Kubernetes Advocate at CNCF" (most recent + consistent)

Step 3: Synthesize Biography

Write a 2-3 paragraph biography (300-500 words) following this structure:

Paragraph 1: Current Role and Focus

• Introduce presenter with full name
• State current role and organization
• Describe primary responsibilities or focus areas
• Mention geographic location

Paragraph 2: Expertise and Involvement

• Describe technical expertise areas
• Highlight specific projects or technologies
• Mention organizational involvement (SIGs, working groups)
• Describe scope of work (what they work on)

Paragraph 3: Community Presence

• Mention speaking engagements or presentations
• Describe contribution to the community
• Note areas of advocacy or thought leadership
• Connect to broader impact or mission

Tone Guidelines:

• Third-person narrative ("Jeffrey Sica is..." not "I am...")
• Professional and factual
• Present tense for current activities
• Avoid marketing language or superlatives
• Use concrete, verifiable statements

Step 4: Compile Metadata

Organizations:

• Normalize organization names (proper capitalization)
• Include all affiliations mentioned in sources
• Order by prominence (primary employer first)

GitHub Data:

• Extract github_username from input profile
• Extract followers count directly from input profile (pass through as-is)

Social Profiles:

• Construct full URLs from usernames
• GitHub: https://github.com/{username}
• Twitter: https://twitter.com/{username} (if available)
• Website: Use exact URL from GitHub blog field
• Only include profiles explicitly mentioned in sources

Step 5: Validate Output

Before returning, verify:

• Full name matches GitHub profile
• Current role is from most recent source
• Location is exact string from GitHub
• Biography is 300-500 words
• Biography uses third-person voice
• All organizations are properly capitalized
• GitHub username is correct
• Followers count matches input (pass-through)
• All social profile URLs are valid
• No speculative or inferred information

Common Pitfalls to Avoid

❌ Speculation and Inference

Bad:

"Maria is likely one of the most influential voices in the GitOps community"

Why: Not stated in sources, speculative superlative

Good:

"Maria contributes to Argo CD and Helm projects and shares GitOps insights as a CNCF Ambassador"

❌ Marketing Language

Bad:

"Sarah is a rockstar engineer who revolutionized cloud infrastructure at Acme Corp"

Why: Hyperbolic, not factual

Good:

"Sarah Chen is a Cloud Native Engineer at Acme Corp, specializing in service mesh and observability"

❌ First-Person Voice

Bad:

"I work on Kubernetes contributor experience at CNCF"

Why: Biography should be third-person

Good:

"Jeffrey works on Kubernetes contributor experience at CNCF"

❌ Vague Descriptions

Bad:

"Alex does various things in the cloud-native space"

Why: Not specific or informative

Good:

"Alex focuses on observability and monitoring solutions for cloud-native applications"

❌ Unverifiable Claims

Bad:

"Maria is an expert in all CNCF projects and has contributed to dozens of repositories"

Why: Cannot be verified from input sources

Good:

"Maria contributes to Argo CD and Helm projects"

❌ Missing Source Priority

Bad: Using old video description role when GitHub profile shows current role

Good: Prioritize GitHub profile for current information

Important Notes

• This skill feeds into presenter-profile-generation skill
• Biography quality directly impacts profile completeness
• Be conservative - better to omit than to speculate
• When sources are sparse, keep biography brief but accurate
• Organizations array feeds into stats table generation
• Social profiles enable user discovery and verification
