At a glance

- Binding the current Claude Code or Codex session before building a result package
- SKILL.md covers 子命令, 证据规则 and 边界
- Runs Python scripts from its folder; calls python3
- Recording a session ID and transcript hash without copying the transcript
What it does
A fixed-path report named session-binding-report.json is generated for Nucleus V2 workflows, inside the run's session-binding folder. It records only the native session ID, an explicit transcript path and a hash, and never copies transcript or JSONL contents. The SKILL.md is written in Chinese.
A Python script offers three subcommands: collect, freeze and validate-report. Evidence rules put explicit context or CLI metadata first, treat Codex JSON events and Claude hook JSON as reliable, accept the CODEX_THREAD_ID variable only as a candidate that strict modes reject on its own, and forbid guessing a transcript by latest file, modification time or only file. Strict modes, or a constraint requiring binding, produce a blocker when no reliable binding exists, and the hash is computed only for completed, cancelled or freeze-requested runs.
When your agent uses it
- Binding the current Claude Code or Codex session before building a result package
- Recording a session ID and transcript hash without copying the transcript
- Validating an existing session binding report
- Freezing the binding when a run completes or is cancelled
Example prompts
- “Collect the session binding for this Nucleus workflow run before we build the result package.”
- “Validate the session-binding-report.json from the last run.”
- “Freeze the session binding now that the run is complete.”
Requirements
- Python 3 to run scripts/session_binding.py
- A Nucleus V2 workflow with its context file
What it can do on your machine
Read from SKILL.md and the folder at commit 3c82085. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Nucleus Session Binding Report loads about 477 tokens when it runs, and up to ~813 if it reads all its reference files. Until then it costs about 45 tokens; SKILL.md has 92 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Session Binding
本 Skill 为 Nucleus V2 workflow 生成固定路径的 session binding report：
.nucleus/runs/<workflowRunId>/session-binding/session-binding-report.json
它只记录原生会话 ID、显式 transcript 路径和 hash，不复制 Claude/Codex transcript 或 JSONL 正文。

- explicit context / CLI metadata 优先。
- Codex JSON event 和 Claude hook JSON 是可靠 event evidence。
CODEX_THREAD_ID只能作为local-verified-env-candidate；strict/PMS 模式不接受单独 env candidate。- Claude transcriptPath 只接受 hook JSON、explicit metadata、CLI 参数或 PMS connector 明确输出。
- 禁止
discoveryMethod=latest|mtime|only-file。 - 禁止 transcript 正文、message array、JSONL event array 进入 report。
- strict/PMS 或
constraints.sessionBindingRequired=true缺可靠绑定时必须输出 blocker。
边界
- 不 import 根
harness/。 - 不写
docs/requirement/**。 .nucleus/runs/<workflowRunId>/session-binding若是 symlink，runtime 输出 stdout blocked payload，不写仓库文件。- transcript hash 只在
