lfx-self-serve: Skill for Claude Code

.claude/skills/lens-persona/SKILL.md

lens-persona is a skill for Claude Code from linuxfoundation/lfx-self-serve. It costs 74 tokens per session (671 once invoked), scanned A, original, MIT.

A set of instructions for code that changes its screens or behavior by user role, called a persona or lens. Examples include Contributor, Maintainer, executive director, board member, and admin views.

In plain words
What is it for?
Use it when changing Self Serve dashboards, persona-aware components, lens switching, or services that decide what a user can see or edit.
Why use it?
It helps developers apply the right permissions and navigation for each type of user. It also points them to the relevant architecture and impersonation guidance before making changes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

lens-persona scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Self Serve Lens & Persona Skill

You are working on code that depends on the Self Serve lens/persona system: dashboards, persona-aware components, the lens switcher, or any conditional behavior driven by LensService or ProjectContextService.

When to use

  • The user mentions "lens", "persona", "PCC", "ED mode", "Admin Mode", "Maintainer view", or any persona variant.
  • A change touches dashboards/ modules.
  • A component needs to gate UI behind persona checks (isMaintainer, isVisitor, canEdit, hasPMOAccess, or an ED check via PersonaService / executiveDirectorGuard).
  • A change touches LensService, ProjectContextService, or persona helpers.
  • A change touches apps/lfx-one/src/server/utils/persona-helper or auth-helper.

Workflow

  1. Re-read docs/architecture/frontend/lens-system.md (the reference linked below) plus docs/architecture/frontend/permission-persona-navigation-model-preread.md for the navigation/permission model.
  2. For backend persona work, also read docs/architecture/backend/impersonation.md.
  3. Identify which persona(s) the change applies to and call them out explicitly in the plan. Self Serve personas are: Contributor, Maintainer, ED, Board Member. Admin Mode is a privileged variant for EDs and admins.
  4. Gate UI with the right signal — !myRoleLoading() && !isVisitor() (not just !isVisitor()) so content does not flash while the role is loading. This is a documented learnings-reviewer pattern.
  5. Do not duplicate persona detection — funnel through LensService / ProjectContextService / the relevant persona helper.
  6. For permission changes (adding/removing/changing canEdit(), isVisitor(), hasPMOAccess()), document the change in the PR description.
  7. Coordinate with the persona backend service when shapes change — lfx-v2-persona-service owns the persona aggregation contract; treat it as a peer repo.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
