At a glance

Locates, lists, filters, and extracts structured data from Claude Code native session logs.

  • Works in 4 steps: locate-logs.sh → list-sessions.sh → extract-data.sh → …
  • Tasks that involve Schema markup
  • SKILL.md covers Core Responsibility, Available Scripts, Working Process and Context Budget Management, plus 6 more sections
  • Runs Shell scripts from its folder; calls jq and bash

What it does

Extracting Session Data is an agent skill from bitwarden/ai-plugins, published by the product's own GitHub organization. Locates, lists, filters, and extracts structured data from Claude Code native session logs. Supports both single and multiple session analysis.

Its SKILL.md is about 2.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts (for example `README.md`, `scripts/extract-data.sh` and `scripts/filter-sessions.sh`).

It sits in Product & Project Management, covering Schema markup. The repository describes itself as: AI plugin marketplace.

When your agent uses it

  • Tasks that involve Schema markup

Example prompts

  • “/extracting-session-data”

Requirements

  • A Bash shell

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. locate-logs.sh
  2. list-sessions.sh
  3. extract-data.sh
  4. filter-sessions.sh

What it can do on your machine

Read from SKILL.md and the folder at commit 0047fdf. 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 4 files in scripts/ (Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • jq
    • bash

    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

Extracting Session Data loads about 2.5k tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 644 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~42
When it runs · the whole SKILL.md, loaded when a task matches
~2.5k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 644 words (~2,472 tokens).

“Provide raw access to Claude Code session logs stored in ~/.claude/projects/{project-dir}/{session-id}.jsonl.”
