universal-live-check

universal-live-check is a skill for Claude Code, Codex from lindoelio/spec-driven-steroids. It costs 108 tokens per session (3,192 once invoked), scanned A, original, MIT.

A software validation framework that checks changed code and configuration according to the software area and type of change, such as a feature, bug fix, migration, or documentation update.

In plain words
What is it for?
Use it to select and run incremental checks for backends, frontends, command-line tools, mobile apps, embedded software, libraries, and related configuration.
Why use it?
It helps catch issues specific to the project’s domain instead of relying only on generic checks that may miss configuration or platform problems.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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

universal-live-check 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 10d 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.

Universal Live Check Framework

Validate code changes in real-time with domain-adaptive, change-type-aware checks. Every check is incremental (only validates what changed), fast (<2s), and deterministic.

Gotchas

Generic checks miss domain bugs: A TypeScript-only check will miss Docker misconfigurations, missing environment variables, or mobile-specific API level issues. Always detect the domain first.

Blocking on slow checks kills flow: Live checks must be fast. Offload heavy checks (integration tests, full test suites) to async pipelines. Live checks verify immediately-correctable issues.

Change type changes strategy: A hotfix needs minimal validation to unblock deployment. A feat needs full API contract verification. Always determine change type before selecting checks.

Scope creep in libs: Library changes affect downstream consumers. A libs domain check must verify public API surface and semver compliance even for "minor" changes.

Quick Start

Input:  Files changed (or files to check), optional change type (feat|fix|hotfix|refactor|migrate|docs)
Output: Structured check report with pass/fail per check category

Workflow:
1. Classify domain(s) affected by the change
2. Determine change type via branch/commit/message analysis
3. Select checks per domain + change type
4. Run incremental checks (file-level first, then module-level)
5. Aggregate results into structured report
6. If failures: provide specific fix actions, not just symptoms

Activation

Load this skill when:

  • User asks for live checks, lint validation, or code quality checks
  • User mentions pre-commit, pre-push, or CI pre-flight
  • Agent is about to complete a coding session and needs validation
  • User asks to "verify", "check", "validate", or "test" code changes
  • User asks to "run checks" or "check my work"
  • Agent detects domain change (CLI→backend, frontend→mobile, etc.)

Do NOT load this skill for:

  • Running full test suites (delegate to CI async pipeline)
  • Questions about code without validating anything
  • Already-passed checks that don't need re-running

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.
