1c-ssl-skills: Skill for Claude Code

.agents/skills/evaluation/SKILL.md

evaluation is a skill for Claude Code, Codex from brake71/1c-ssl-skills. It costs 40 tokens per session (3,152 once invoked), scanned A, a copy of evaluation, MIT.

An evaluation framework for measuring how well AI agents perform over time. It uses repeatable checks, comparison baselines, scoring criteria, quality gates, and production monitoring.

In plain words
What is it for?
It helps build regression suites, outcome measurements, multi-part scoring rubrics, deployment checks, and ongoing monitoring for agent pipelines.
Why use it?
AI agents can make different decisions on different runs and may not have one correct answer. This helps find regressions, compare changes, and decide whether an agent is ready to use.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is brake71/1c-ssl-skills's own configuration. It tells Claude Code and Codex how to work on 1c-ssl-skills itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything 1c-ssl-skills configures →

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

evaluation 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 17d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/evaluator.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Evaluation Methods for Agent Systems

Evaluate agent systems differently from traditional software because agents make dynamic decisions, are non-deterministic between runs, and often lack single correct answers. Build evaluation frameworks that account for these characteristics, provide actionable feedback, catch regressions, and validate that context engineering choices achieve intended effects.

When to Activate

Activate this skill when:

  • Testing agent performance systematically
  • Validating context engineering choices
  • Measuring improvements over time
  • Catching regressions before deployment
  • Building quality gates for agent pipelines
  • Comparing different agent configurations
  • Evaluating production systems continuously

Do not activate this skill for adjacent work owned by other skills:

  • Designing the LLM judge itself, pairwise comparison, judge calibration, or bias mitigation: advanced-evaluation.
  • Designing autonomous control surfaces, novelty gates, rollback, or PR approval boundaries: harness-engineering.
  • Debugging a specific context failure mode before measuring it: context-degradation.

Core Concepts

Focus evaluation on outcomes rather than execution paths, because agents may find alternative valid routes to goals. Judge whether the agent achieves the right outcome via a reasonable process, not whether it followed a specific sequence of steps.

Use multi-dimensional rubrics instead of single scores because one number hides critical failures in specific dimensions. Capture factual accuracy, completeness, citation accuracy, source quality, and tool efficiency as separate dimensions, then weight them for the use case.

Use model-judged evaluation only after deterministic checks and rubrics are stable. When the work centers on judge prompts, pairwise comparison, calibration, or bias mitigation, switch to Advanced Evaluation.

Run deterministic validation before LLM judgment whenever the artifact has machine-checkable structure. Schema validity, duplicate keys, rubric math, manifest sync, retrieval status, and required evidence paths should fail fast before an evaluator spends tokens or returns a subjective score.

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.
