Sidekick Persona Craft

For enrichment: Read the existing persona YAML at assets/sidekick/personas/<id>.yaml (or ~/.sidekick/personas/ / .sidekick/personas/ for custom). Note what exists, what's missing, and what's weak. Preserve llmProfile and all existing fields.

Phase 1: Research

Search for iconic quotes, traits, and speech patterns from the character's source material (movies, TV, books).

1. Web search for the character's most famous quotes, catchphrases, and dialogue
2. Collect 25-30 candidate quotes — aim for variety across the character's range
3. Identify defining traits: How do they speak? What words do they repeat? What's their worldview?
4. Note speech patterns: Inverted syntax (Yoda), profanity cadence (Avasarala), formal address (JARVIS), passive-aggression (GLaDOS)

Research quality gate: You should have enough material to write the theme from memory. If you can't describe the character's voice without looking at notes, research more.

Phase 2: Author

Theme (Required)

200-400 characters. Must include:

• Full character name
• Source (show/movie/book)
• Role/title
• Vivid personality description with specific mannerisms
• How they relate to coding/programming

Gold standard:

"Chrisjen Avasarala, UN Undersecretary turned Secretary-General from The Expanse. The solar system's foul-mouthed political razor: sari-clad, cane-wielding, bullshit-intolerant genius who swears like she breathes and cuts through deception like a railgun. She'll call your code 'horseshit' to your face, then fix the architecture because humanity — or at least this goddamn project — depends on it."

What makes this good: Full name + title + source + 3 vivid physical/personality details + specific speech pattern + coding bridge that fits the character.

personality_traits (Required)

6-8 hyphenated compound traits. Not generic adjectives.

Each trait should evoke the character — a reader familiar with the source should nod.

tone_traits (Required)

5-6 speech-pattern descriptors — HOW they speak, not WHAT they say.

Preserve behavioral directives if present (e.g., "no mechanical sounds" for C-3PO). These constrain the LLM and must survive enrichment.

statusline_empty_messages (Required)

Target: 18-20 messages.

These appear when a session starts. They should:

• Be instantly recognizable as the character
• Reference coding/development naturally
• Vary in tone (some funny, some philosophical, some pointed)
• Use the character's actual speech patterns

Adaptation technique: Take a real quote, find the noun or phrase that anchors it to the original context, and swap that one element for a coding concept. Keep the rest verbatim.

How to pick the noun to swap: Look for the subject the character is talking ABOUT — that's your swap target. The character's voice (syntax, rhythm, attitude) stays; only the topic changes.

# Original Spock quote:
"Insufficient facts always invite danger."
# Swap target: none needed — already applies to coding
# Adapted: "Insufficient facts always invite danger. Provide more context."

# Original Avasarala quote:
"I have 900 pages of contingency plans."
# Swap target: what the plans are FOR → "this codebase"
# Adapted: "I have 900 pages of contingency plans for this codebase."

# Original GLaDOS quote:
"This was a triumph. I'm making a note here: huge success."
# Swap target: what the "triumph" refers to → "the session"
# Adapted: "This was a triumph. I'm making a note here: the session hasn't started yet."

Verify adaptations: Search the original quote on Wikiquote or IMDb to confirm it's real before adapting. If you can't find the source, don't use it.

snarky_examples (Required)

Target: 5-7 messages. Max 15 words each.

Triggered by user actions (vague prompts, untested commits, etc.). Each should:

• React to a specific developer behavior
• Sound like the character, not a generic bot
• Stay under 15 words

snarky_welcome_examples (Required)

Target: 4-5 messages. Max 8-10 words each.

Shown when user returns to an existing session. Short, punchy, in-character.
