case-forensics

case-forensics is a skill for Codex from dzhokhov/markdown-agent-vault-ru. It costs 88 tokens per session (704 once invoked), scanned A, original, MIT.

A method for extracting a repeatable case study from long threads, comments, or chat discussions about AI work. It records the timeline, evidence, steps, results, limits, and missing information.

In plain words
What is it for?
Use it to reconstruct decisions and actions, map supporting evidence, document how to repeat the work, measure outcomes, and list questions that still need answers.
Why use it?
It turns scattered conversation into a method another person can follow and check. It also separates confirmed facts from assumptions and gaps.

Skill for Codex

Written for Codex: agents/openai.yaml present.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is Навигация: [Индекс скиллов](../README.md).

Good fit Use it to reconstruct decisions and actions, map supporting evidence, document how to repeat the work, measure outcomes, and list questions that still need answers.

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

case-forensics 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 8d 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.

Case Forensics

Навигация: Индекс скиллов

Overview

Преобразуй неструктурированное обсуждение в воспроизводимый кейс уровня инструкции.

Скилл отвечает за фазу thread -> evidence map -> method extraction -> reproducibility report.

Workflow

1) Parse Timeline

Восстанови хронологию:

  • кто действовал,
  • какие решения принимались,
  • какие изменения вносились,
  • что было результатом.

2) Build Evidence Map

Каждый тезис маркируй:

  • EVIDENCE — подтверждён сообщением/артефактом
  • ASSUMPTION — вывод без прямого доказательства
  • GAP — критично не хватает данных

3) Extract Method

Собери метод в последовательные шаги:

  • входные условия
  • действия
  • инструменты/промты
  • контроль качества
  • критерий завершения

4) Quantify Outcome

Зафиксируй:

  • метрики before/after
  • тип эффекта (время/деньги/качество/риск)
  • что не сработало

5) Reproducibility Score

Оцени воспроизводимость по контракту из case-data-contract:

  • input_completeness
  • method_specificity
  • artifact_availability
  • metric_verifiability

6) Prepare Final Case

Выдай:

  • структурированный кейс
  • инструкцию «как повторить за 120 минут»
  • блок GAP + вопросы для доуточнения из gap-interview-questions

Output

Возвращай разделы:

  1. Контекст и цель
  2. Исходные условия
  3. Метод (шаги)
  4. Материалы/промты/инструменты
  5. Результат и метрики
  6. Что не сработало
  7. Репликация за 120 минут
  8. Границы переносимости
  9. GAP и вопросы

Quality Gates

  • Нет шагов без входа/выхода.
  • Любая числовая метрика имеет источник в треде.
  • Любая гипотеза без подтверждения помечена как ASSUMPTION.
  • Есть явные ограничения применимости кейса.

Anti-Patterns

  • Не выдавать «историю успеха» как методологию.
  • Не скрывать провалы/ограничения.
  • Не подменять GAP догадками.

What ships with it

6 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.

case-forensics is a skill published in the GitHub repository dzhokhov/markdown-agent-vault-ru (2 stars, last pushed yesterday), licensed MIT. It adds 88 tokens to every session and 704 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
