Session Logger

Create a compact recovery artifact without treating raw conversation history as durable memory.

Use This Skill When

• The user explicitly asks to save or record the current session.
• A supported host invokes the Agent Playbook SessionEnd hook with a transcript path.
• A later task needs a concise handoff artifact and the user has authorized writing it.

Do not silently persist raw transcripts, credentials, private customer data, or unbounded agent output. Host support and write authority must be visible; skill metadata alone does not execute a hook.

CLI Runtime Contract

Claude Code installation can invoke:

agent-playbook session-log

The command reads the host-provided JSONL transcript and stores only bounded, redacted details:

• message counts;
• the last user prompt, truncated after redaction;
• up to 12 detected commands and file references;
• up to 8 detected questions;
• a hashed session reference and project identity.

By default, files are private local artifacts:

~/.agent-playbook/sessions/<project-id>/YYYY-MM-DD-<topic>.md

Set AGENT_PLAYBOOK_DATA_DIR or pass --data-dir to move the private data root. Writing inside a repository is opt-in only:

apb session-log --session-dir ./sessions

If a repository-local directory is selected, verify its ignore and retention policy before writing. Never assume another repository ignores sessions/.

Manual Summary Contract

When the host cannot provide a transcript event, create a user-authorized summary from the context actually visible in the current session. Include only:

1. outcome and current state;
2. decisions that affect future work;
3. relevant files or commands;
4. open questions and next proof gate.

State omissions honestly. Do not claim full conversation capture, structured decision extraction, automatic append behavior, or cross-session recall unless the active runtime demonstrably provides it.

Privacy and Safety

• Redact common credentials, bearer tokens, private keys, email addresses, and password/secret assignments before writing.
• Replace the current project root with a project identity in generated metadata.
• Write generated summaries with owner-only permissions where the platform supports it.
• Keep the artifact local unless the user separately authorizes commit, upload, or sharing.
• Treat redaction as risk reduction, not a guarantee that arbitrary confidential text is safe.

Completion Check

• Destination and write authority are clear.
• The summary is bounded and contains no known raw secret.
• Repository-local storage was explicitly selected and ignore policy checked.
• The returned path exists and is readable by the user.
