Casting personas: rapid generation from diverse inputs, registry-based persistence and lifecycle, data-driven evolution, inter-agent sync. Not for UI walkthroughs (Echo) or user research (Field).

Cast Generation Workflows

Purpose: Define the CONJURE workflow, source detection order, synthesis rules, validation thresholds, and registration behavior.

Contents

  1. Source detection
  2. Input quality
  3. Extraction strategy
  4. Synthesis rules
  5. Validation
  6. Registration
  7. Auto-triggers
  8. Internal personas

Source Detection

When no explicit path is provided, detect sources in this order.

External / User Persona Sources

Priority Source Use for Confidence contribution
P0 .agents/personas/ Adopt or enrich existing personas —
P1 README.md User types, product promise, usage context +0.10
P2 docs/**/*.md User guides, personas, workflows +0.15
P3 src/**/auth*, src/**/user* Roles, auth, user models +0.15
P4 src/**/checkout*, src/**/onboard* Key journeys, conversion friction +0.15
P5 tests/e2e/** User stories encoded in tests +0.10
P6 package.json, *.config.* Product metadata and flags +0.05

Internal Persona Sources

Priority Source Use for
P0 CODEOWNERS Team structure and responsibility
P1 docs/CONTRIBUTING.md Development process
P2 .vscode/**, .idea/**, .editorconfig Editor/workflow setup
P3 docker-compose*.yml Local dev context
P4 .github/workflows/* CI/CD patterns
P5 Makefile, scripts/** Commands and automation
P6 docs/runbook*, docs/onboarding* Operational and onboarding context

Input Quality Assessment

Factor High Medium Low
Explicitness User type stated directly Implied Guessed from filenames
Recency Updated within 30 days Updated within 90 days 90+ days stale
Specificity Named user types with details General user mention No user mention
Breadth Multiple dimensions covered Partial coverage One dimension only

Extraction Strategy

Source type Extract
Documentation user types, goals, pain points, usage scenarios, language cues
Code roles, flows, permissions, friction points, feature flags
Tests user stories, expected flows, success criteria, fixtures
Field handoff quotes, goals, pain points, segment findings
Trace handoff behavior clusters, device mix, drop-off points
Voice handoff feedback themes, promoters/detractors, segment drift

Extraction Output

Produce structured extraction output with:

  • service_context
  • user_types
  • goals
  • pain_points
  • behaviors
  • contexts
  • evidence

Synthesis Rules

  1. Generate at least 3 personas by default: P0, P1, P2.
  2. Assign an echo_base_mapping to every persona.
  3. Record evidence for every non-trivial attribute.
  4. Mark unsupported attributes as [inferred].
  5. Calculate confidence from source and validation contributions.

Priority Assignment

Priority Criteria
P0 Most common or strongest evidence
P1 Second-most common or business-critical
P2 Edge case, underserved segment, or high-friction segment
P3+ Only if evidence strongly supports additional segments

Detail Level Selection

Condition Detail level
User explicitly requests a level Requested level
4+ extended dimensions available Full
2-3 extended dimensions available Standard
type == internal Internal
Otherwise Minimal

Validation

Echo Compatibility

Check Rule Failure action
Frontmatter Echo-required fields present Add safe defaults
Profile Includes core role/context fields Infer cautiously from evidence
Quote Non-empty Compose from goals and frustrations
Goals / Frustrations / Behaviors Keep 3 each Merge or split to reach 3
Emotion Triggers Cover the expected polarity spread Generate from context
Echo Testing Focus At least 3 flows Derive from JTBD
Source Analysis At least one source Block generation

Consistency Checks

  • Tech level must fit behaviors.
  • Device emphasis must fit context scenarios.
  • Goals and frustrations must not contradict each other.
  • Echo mapping must match the dominant trait.

Confidence Thresholds

Confidence Status Action
>=0.60 active Ready for use
0.40-0.59 draft Usable with enrichment warning
<0.40 draft Warn and ask before relying on it

Registration

File Operations

  1. Create .agents/personas/{service-name}/ if missing.
  2. Write persona file as {persona-name}.md in kebab-case.
  3. Update .agents/personas/registry.yaml.
  4. Return a concise registration summary.

Naming Rules

  • Service name: kebab-case.
  • Persona name: kebab-case.
  • Internal personas stay in the same service directory and are distinguished by type: internal.

Registration Summary

Return:

  • service
  • personas generated
  • detail level
  • registry updated
  • persona table with priority / echo mapping / confidence / file
  • analyzed sources
  • recommended next command

Auto-Detection Triggers

Suggest Cast automatically when:

  1. Echo has no saved personas.
  2. Field completes persona creation.
  3. Trace delivers behavioral drift data.
  4. A new service is added to the project.

Internal Persona Rules

  • Set type: internal.
  • Include Internal Profile and Workflow Context.
  • Map to an internal Echo base persona.
  • Focus emotion triggers and testing focus on workflow and DX concerns.

  • Gen Agent Trust Hub13d

    The skill is functionally safe but maintains a surface for indirect prompt injection because it processes external repository files and agent data to generate personas without explicit sanitization. It uses standard data science libraries and well-known text-to-speech tools.
