Session State Tracker

External Endpoints#

This skill does not call any external endpoints. All operations are local to the workspace.

Security & Privacy#

• Fully local operation: No network access; all state is stored in SESSION_STATE.md within the workspace.
• File scope: The skill reads and writes only SESSION_STATE.md in the workspace root. No other files are accessed.
• Session discovery: The session_state_discover tool uses memory_search, which may query indexed session transcripts. This is governed by your OpenClaw memorySearch configuration (local vector DB). No external API calls are made by the skill itself.
• No data exfiltration: Nothing leaves your machine unless you have configured external memory backends separately.

Model Invocation Note#

The skill registers three lifecycle hooks:

• pre-compaction: runs automatically before compaction to persist state.
• post-compaction: runs automatically after compaction to inject a state reminder.
• session-start: runs automatically at session start to load fresh state.

These hooks are triggered by OpenClaw's core; no agent intervention is required. The tools ( session_state_read, session_state_write, session_state_discover) are available for manual use when desired.

Trust Statement#

By using this skill, all state management remains local and transparent. The code is open-source and operates solely on your SESSION_STATE.md file. Only install if you trust the author and understand the hook automation.

Overview#

The Session State Tracker solves context loss during OpenClaw session compaction and restarts by automatically persisting and restoring working state through lifecycle hooks.

Key Features#

• Automatic state persistence via OpenClaw hooks (no manual steps during compaction).
• Schema-validated state file ( SESSION_STATE.md) with YAML frontmatter.
• Atomic writes to prevent corruption.
• Discovery tool to rebuild state from session transcripts if needed.
• CLI for manual inspection and updates.
• Zero external dependencies beyond Node.js and js-yaml.

File Format#

SESSION_STATE.md (workspace root):

markdown

---
project: "my-project"
task: "Describe current task"
status: "active"          # active | blocked | done | in-progress
last_action: "Latest update"
next_steps:
  - "Step 1"
  - "Step 2"
updated: "2026-02-14T23:20:00.000Z"
---

## Context
Optional freeform notes, constraints, links, etc.

All frontmatter fields are required except body (the Context section). Timestamps must be ISO 8601.

---

Installation#

bash

clawhub install qsmtco/session-state-tracker

Or copy the skill folder into skills/session-state-tracker/ and enable in openclaw.json:

json

"skills": { "entries": { "session-state-tracker": { "enabled": true } } }

Then restart the gateway.

---

Configuration#

The skill works out of the box with hooks enabled. Ensure session transcript indexing is active for session_state_discover to be effective:

json

"agents": {
  "defaults": {
    "memorySearch": {
      "sources": ["memory", "sessions"],
      "experimental": { "sessionMemory": true }
    }
  }
}

No other configuration required.

---

Tools#

• session_state_read – read current state (frontmatter + body)
• session_state_write – update fields (auto-timestamps, validates schema)
• session_state_discover – synthesize state from recent sessions and write it

---

CLI#

bash

# Show state
session-state show

# Update a field
session-state set task "New task"
session-state set next_steps '["A","B"]'

# Refresh from session transcripts (requires memory_search)
session-state refresh

# Clear state
session-state clear

---

How It Works#

1. Session start: session-start hook reads SESSION_STATE.md; if present and fresh (<24h), injects a summary into the initial system context.
2. During work: You may call session_state_write to record progress. The file is the single source of truth.
3. Pre-compaction: pre-compaction hook automatically saves the current state (via discovery if needed) without agent involvement.
4. Post-compaction: post-compaction hook injects a [State Anchor] reminder so the agent re-anchors instantly.
5. Restart: The cycle repeats; state persists across restarts.

---

Migration from v1.x#

v2.0.0 introduces lifecycle hooks. No changes to SESSION_STATE.md format. To upgrade:

• Install v2.0.0 (or later).
• Ensure the skill is enabled.
• The hooks replace the old memoryFlush.prompt convention; you may remove any custom prompt from your config.
• Existing SESSION_STATE.md files continue to work unchanged.

---

Troubleshooting#

• Hooks not firing? Verify the skill is enabled and the plugin manifest ( openclaw.plugin.json) is present. Restart the gateway after installation.
• session_state_discover returns empty? Enable session transcript indexing ( memorySearch.experimental.sessionMemory = true) and ensure recent conversation exists.
• State file not updating? Check file permissions; the skill writes atomically to SESSION_STATE.md in the workspace root.

Minimal, reliable, and automatic.
