cameo-live-validation

cameo-live-validation is a skill for Claude Code, Codex from ajhcs/cameo-mcp-bridge. It costs 27 tokens per session (377 once invoked), scanned A, original, MIT.

A workflow for checking and using a local Cameo bridge, including its connection, open project, available functions, and results. Cameo is the connected modeling tool this workflow is designed to inspect.

In plain words
What is it for?
Probing the bridge, reading compact project or diagram data, checking matrices, and validating live model changes.
Why use it?
It prevents agents from claiming that a live model change worked without checking the bridge and verifying the result.

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

cameo-live-validation 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 11d 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.

What it actually says

Cameo Live Validation

Use this skill when working against the local Cameo bridge in Codex.

Operating rules

  1. Start every live session with:
    • cameo_probe_bridge
    • cameo_status
    • cameo_get_capabilities
    • cameo_get_project
  2. Treat bridge health and open-project readiness as separate checks.
  3. Prefer compact reads first:
    • view="compact"
    • filtered queries
    • paged containment reads
    • metadata-only image access before full image payloads
  4. Before claiming success, use verification tools when available:
    • cameo_verify_diagram_visual
    • cameo_verify_matrix_consistency
    • semantic validation helpers
  5. Escalate to live scripts only for real smoke or regression work, not every small read.

Compact defaults

  • Do not dump full containment trees unless the task truly needs them.
  • Prefer narrow package scopes and exact type filters.
  • For diagrams, read the artifact metadata before requesting rendered images.
  • For matrix work, inspect row and column counts plus populated cell summaries before pulling full details.
  • Summaries in Codex should separate done, failed, and blocked instead of pasting raw payloads.

Regression boundary

Use the repo's live scripts only when validating an end-to-end capability claim:

  • mcp-server/scripts/live_validate_bridge_surface.py
  • mcp-server/scripts/live_validate_flow_properties.py
  • mcp-server/scripts/live_validate_matrices.py

See the reference notes in references/preflight.md, references/compact-read-patterns.md, and references/live-regression.md.

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

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.
