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 | $0.00011 | $0.02055 |
| Opus 5 | $0.00005 | $0.01027 |
| Sonnet 5 | $0.00002 | $0.00411 |
| Haiku 4.5 | $0.00001 | $0.00205 |
Grade A, and why
history 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 11d ago.
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 — 244 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Claude History Query Skill
You are using the claude-history CLI tool to query Claude Code's agent history storage.
Note: If
claude-historyis not installed or you encounter issues, see README.md for installation and troubleshooting instructions.
Agent Delegation (Required)
This skill must delegate all tool use to the history-search agent. Do not call claude-history directly from the skill.
- Invoke the
history-searchagent (from.claude/agents/registry.yaml). - Pass a fenced JSON payload that matches the agent's Input Contract.
- Receive a fenced JSON envelope and format the result for the user.
Usage Instructions
Available Commands
-
list - List projects or sessions
claude-history list [path] -
query - Query history with filters
claude-history query <path> [flags] -
tree - Show agent hierarchy
claude-history tree <path> --session <session-id> -
find-agent - Find agents by task description
claude-history find-agent <path> [search-terms...] -
export - Export session to HTML
claude-history export <path> --session <session-id> [flags] -
resolve - Resolve paths (debugging)
claude-history resolve <path> [flags]
Common Flags
--session <id>- Filter by session ID (supports git-style prefixes)--agent <id>- Filter by agent ID (supports git-style prefixes)--type <types>- Filter by entry types (user,assistant,system,etc.)--start <date>- Filter entries after date (YYYY-MM-DD)--end <date>- Filter entries before date--tool <name>- Filter by tool name (exact match)--tool-match <pattern>- Filter by tool name pattern (regex)--format <fmt>- Output format: text, json, tree, html (default: text)--output <file>- Write output to file
Workflow Based on User Request
When user provides a path:
- Delegate
listto the agent to see available sessions - If they want to explore a specific session, delegate
treeto see agent hierarchy - Delegate
querywith appropriate filters to get detailed information - Delegate
find-agentto search for agents working on specific topics
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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 is a skill published in the GitHub repository randlee/claude-history (5 stars, last pushed 3mo ago), licensed MIT. It adds 11 tokens to every session and 2,055 once invoked, about $0.0001 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 2026-08-31.
