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:

Prioritize GitHub profile for current role and location (most up-to-date)
Use most recent video for role descriptions (check dates)
Cross-reference multiple sources for consistency
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

Quality Guidelines

Factual Accuracy

Every claim must be traceable to input sources
Use exact wording from sources when possible
Do not infer relationships, roles, or expertise
When sources conflict, use most recent and authoritative

Biography Style

Length: 300-500 words (2-3 paragraphs)
Voice: Third-person narrative
Tense: Present tense for current activities
Tone: Professional, factual, respectful
Structure: Role → Expertise → Community presence

Metadata Completeness

Include all organizations mentioned in sources
Construct valid URLs for all social profiles
Use exact location string from GitHub
Normalize organization names (proper caps)

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
