agent-session-parser: Instructions file for Codex

AGENTS.md

agent-session-parser AGENTS.md is an instructions file for Codex, OpenCode from BobDLA/agent-session-parser. It costs 645 tokens per session, scanned A, original, MIT.

A set of project instructions for working on a Python library that parses session files from Claude Code, Codex CLI, and Gemini CLI. It defines the project boundaries, documentation to read, shared data format, output formats, and test-first development process.

In plain words
What is it for?
Use it when modifying session parsing, JSON or Markdown export, batch processing, fixtures, golden files, integration tests, or provider-specific parsers.
Why use it?
It gives coding agents the context needed to make compatible changes without treating the project as a wrapper for an unrelated Go tool or expanding its scope accidentally.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions Claude Code; mentions AGENTS.md; mentions Codex.

This is BobDLA/agent-session-parser's own configuration. It tells Codex and OpenCode how to work on agent-session-parser 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 agent-session-parser 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

agent-session-parser AGENTS.md 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.

What it actually says

AGENTS.md

本文件给进入 session-parser 仓库工作的代理一个最小但明确的上下文。

项目定位

  • 这是一个独立的 Python 库,目标是解析 Claude Code、Codex CLI、Gemini CLI 的会话文件。
  • 当前主线目标是:稳定解析、批量导出、可复用库接口。
  • 不要把当前仓库当成任何现有 Go CLI 的 Python 包装层。

先读这些文档

  • 当前现状与一期边界:docs/PROJECT_STATUS_ZH.md
  • 使用说明:docs/USAGE_ZH.md
  • 监控/状态快照:docs/MONITORING_ZH.md
  • SessionData contract:docs/SESSION_DATA_CONTRACT_ZH.md
  • TDD 工作方式:docs/TDD_WORKFLOW_ZH.md
  • 项目约束:docs/PROJECT_CONSTRAINTS_ZH.md
  • 二期 backlog:docs/PHASE2_BACKLOG_ZH.md

当前边界

当前已完成的一期能力:

  • Claude / Codex / Gemini 的基础解析
  • 统一 SessionData schema
  • JSON / Markdown emitter
  • 批量导出与对拍脚本
  • fixture / golden / 集成回归

当前不要主动扩进去的范围:

  • watcher
  • ExecAgentAndWatch
  • provider 安装检测
  • 云同步 / analytics / debug raw 写盘
  • 新 provider 扩展

开发方式

  • 采用 TDD:先加失败测试,再实现,再跑全量测试。
  • 优先使用共享 fixture / golden,而不是只写理想化 mock。
  • 修改解析行为时,优先确认:
    • SessionData contract 是否保持稳定
    • JSON / Markdown golden 是否需要同步
    • 是否需要补 Go / Python 对拍

仓库结构

  • 顶层 API:src/session_parser/api.py
  • 共享 core:src/session_parser/core/
  • provider 解析器:src/session_parser/providers/
  • 输出器:src/session_parser/emitters/
  • 测试:tests/

补充:

  • Claude 的 rebuilder 逻辑当前在 src/session_parser/providers/claude/parser.py 的内部辅助函数里。
  • Codex 当前以单文件会话解析为主。
  • parse_project(...) 目前只支持 Claude 与 Gemini。

提交前检查

默认执行:

./scripts/check.sh

如果变更涉及参考项目对拍,优先考虑补或运行:

PYTHONPATH=src python scripts/export_reference_compare.py ...

修改原则

  • 优先保持当前公共 API 稳定。
  • 优先保持 fixture / golden 回归稳定。
  • 优先修“结构性差异”和“真实样本差异”,不要先追长尾展示细节。

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.
