What it does
Session Reader is an agent skill from HazAT/pi-config. Efficiently read and analyze pi agent session JSONL files. Use when asked to "read a session", "review a session", "analyze a session", "what happened in this session", "load session", "parse session", "session history", "go through sessions", or given a .jsonl session file path.
Its SKILL.md is about 810 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts and reference files (for example `references/session-format.md` and `scripts/read_session.py`).
It sits in Development. The repository describes itself as: My personal pi coding agent configuration - skills and extensions. The licence is MIT.
When your agent uses it
- Asked to read a session
- Review a session
- Analyze a session
- What happened in this session
Example prompts
- “read a session”
- “review a session”
- “analyze a session”
- “/session-reader”
Requirements
- Python 3
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 655acd4. 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:
uv
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.
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
Session Reader loads about 808 tokens when it runs, and up to ~2.2k if it reads all its reference files. Until then it costs about 74 tokens; SKILL.md has 284 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.

- description
- Efficiently read and analyze pi agent session JSONL files. Use when asked to "read a session", "review a session", "analyze a session", "what happened in this session", "load session", "parse session", "session history", "go through sessions", or given a .jsonl session file path.
Read Pi Sessions
Parse pi session JSONL files into readable output. Sessions live in ~/.pi/agent/sessions/<project>/ as .jsonl files.
Step 1: Find the Session
ls -t ~/.pi/agent/sessions/*<project>*/*.jsonl | head -10Step 2: Start with Table of Contents
Always start with toc to get a numbered map of the session:
uv run ${CLAUDE_SKILL_ROOT}/scripts/read_session.py <path> --mode tocThis prints a compact numbered list of every user exchange with timestamps and tools used.
Step 3: Read the Conversation
Default mode — shows only user messages and assistant text responses. Tool calls are hidden but hinted at with [used: tool1, tool2].
# Full conversation (default mode)
uv run ${CLAUDE_SKILL_ROOT}/scripts/read_session.py <path>
# Specific range
uv run ${CLAUDE_SKILL_ROOT}/scripts/read_session.py <path> --offset 5 --limit 3
# Search for specific topic
uv run ${CLAUDE_SKILL_ROOT}/scripts/read_session.py <path> --search "error"Step 4: Drill Into a Turn
See everything about a specific exchange — thinking, tool calls, tool results, costs:
uv run ${CLAUDE_SKILL_ROOT}/scripts/read_session.py <path> --mode turn --turn 7Mode Reference
| Mode | Shows | Use for |
|---|---|---|
conversation | User + assistant text only (default) | Reading what happened |
toc | Numbered exchange list | Navigation, finding the right turn |
turn | Full detail for one exchange | Drilling into specifics |
issues | Errors, failures, retries, user complaints | Finding what broke |
overview | Metadata + exchange summaries | Quick session assessment |
full | Everything including tool I/O | Deep debugging |
tools | Tool calls and results only | Understanding agent actions |
costs | Token usage and cost per turn | Cost analysis |
subagents | Subagent task/status/cost/paths | Reviewing delegated work |
Flags
| Flag | Effect |
|---|---|
--offset N | Skip first N exchanges |
--limit N | Show at most N exchanges |
--turn N | Exchange number to drill into (with --mode turn) |
--search TERM | Filter exchanges containing TERM (case-insensitive) |
--max-content N | Max chars per block (default: 3000, 0=unlimited) |
Typical Workflow
--mode toc→ scan the session, find interesting exchanges- Default (conversation) → read the human-readable flow
--mode turn --turn N→ drill into specific exchanges--mode subagents→ review delegated work and follow subagent session paths
Subagent Drill-Down
Subagent session files can be read with the same script:
# From --mode subagents output, grab the JSONL path
uv run ${CLAUDE_SKILL_ROOT}/scripts/read_session.py <subagent-jsonl-path> --mode tocSession Format Reference
Read ${CLAUDE_SKILL_ROOT}/references/session-format.md only if custom parsing is needed.

Can I use Session Reader in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add HazAT/pi-config --skill session-reader -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/session-reader, .gemini/skills/session-reader, .github/skills/session-reader and .opencode/skills/session-reader in your project.
What does Session Reader need to run?
Going by SKILL.md and its folder, Session Reader needs Python for the scripts in its folder and the command-line tools its instructions call (uv). Our summary lists: Python 3.
Does Session Reader access the network?
SKILL.md contains no URLs. Its commands use uv, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Is Session Reader safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Session Reader use?
Session Reader is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Session Reader use?
About 808 tokens (SKILL.md is roughly 3.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 1.4k tokens, read only when the agent opens those files.
