What is history-explorer?

A read-only tool for examining recent conversation turns and tool activity in an agent session.

Use it to inspect turn counts, recent messages, tool usage, skill runs, and recurring tool or skill combinations.

It provides structured history when you need to understand what happened earlier, which tools were used, or how skills were combined.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add clawdotnet/openclaw.net --skill history-explorer

Clone the repo

git clone --depth 1 https://github.com/clawdotnet/openclaw.net

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00065	$0.00770
Opus 5	$0.00032	$0.00385
Sonnet 5	$0.00013	$0.00154
Haiku 4.5	$0.00006	$0.00077

Security

Grade A, and why

history-explorer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/explore.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.

History Explorer

Read-only helper that inspects OpenClaw.NET session history for downstream workflows (especially meta-skill-creator).

What It Does

Parses a JSON session snapshot and returns structured analytics:

Key	Description
`turns`	Turn count, role distribution (`user` vs `assistant`), time span, recent turn previews
`tools`	Tool invocation frequency, top tools, tool co-occurrence in the same turn
`meta_runs`	Meta-skill execution history: skill name, status, step counts, failure codes
`co_occurrences`	Skill/tool pairs that appear together across turns
`placeholder`	Emitted when no session data is available; downstream workflows treat this as a signal to rely on user intent only

Input Contract

The script expects JSON session data on stdin. The calling agent should pipe a JSON object matching the Session schema — specifically:

{
  "id": "session-guid",
  "history": [
    { "role": "user", "content": "...", "timestamp": "..." },
    { "role": "assistant", "content": "...", "timestamp": "...", "toolCalls": [...] }
  ],
  "metaRunHistory": [
    {
      "runId": "...", "skillName": "...", "status": "completed",
      "startedAtUtc": "...", "completedAtUtc": "...",
      "stepResults": [
        { "id": "...", "kind": "...", "status": "...", "durationMs": 123 }
      ]
    }
  ]
}

Output Contract

Always returns a JSON object. When session data is available, includes the requested analytics keys. When unavailable or unparseable, returns a single placeholder key so downstream workflows degrade deterministically.

When to Use

Before running meta-skill-creator: feed co-occurrence and meta-usage data into the creator's proposal draft
When the user asks "what skills did I use recently" or "show my session history"
When debugging: inspect recent tool failures or meta-run error codes
When the agent needs to recall conversation context from earlier turns

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

history-explorer is a skill published in the GitHub repository clawdotnet/openclaw.net (495 stars, last pushed 3d ago), licensed MIT. It adds 65 tokens to every session and 770 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
