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.

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 | $0.00114 | $0.01390 |
| Opus 5 | $0.00057 | $0.00695 |
| Sonnet 5 | $0.00023 | $0.00278 |
| Haiku 4.5 | $0.00011 | $0.00139 |
Grade B, and why
cline-session-history scanned grade B with 1 finding 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 10d 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.
Asks the agent to reveal its instructionsmediumSystem prompt leakage
Directions to print, repeat or translate the system prompt extract configuration the operator did not intend to expose.

Cline Session History
Search and browse Cline session history stored on the local machine. Sessions live in ~/.cline/data/sessions/ as individual JSON metadata files and conversation transcript (.messages.json) files. Older sessions may also be in a sessions.db SQLite database.
When to Use This Skill
- "Find my session from the last hour about..."
- "Find my session that started with this prompt..."
- "Find the session where I asked about..."
- "Show me sessions that used model X"
- "What sessions failed yesterday?"
- "Show me the transcript for session "
- "Export sessions from last week to a folder"
- "What was that session where..."
- Any request involving past Cline conversation history
How to Use
The search script lives alongside this file at scripts/search_sessions.py, relative to the skill's own directory. Resolve it against the directory that contains this SKILL.md — not the current working directory — so it works regardless of where the command is run from.
Script path: scripts/search_sessions.py (relative to this skill's directory)
The examples below use scripts/search_sessions.py; prefix it with the skill directory's absolute path when running from elsewhere.
All filters are optional and combine with AND logic.
Quick Examples
# Sessions from the last 10 minutes
python3 scripts/search_sessions.py --since 10m
# Sessions between two dates with "chatgpt" in the prompt
python3 scripts/search_sessions.py --since 2026-06-01 --until 2026-06-21 --prompt chatgpt
# Find a session by its starting prompt (quoted substring match)
python3 scripts/search_sessions.py --since 1d --prompt "find some code that should be improved" --full-prompt
# Non-interactive sessions that failed
python3 scripts/search_sessions.py --no-interactive --status failed
# VS Code extension sessions using Claude models, full prompts
python3 scripts/search_sessions.py --source vscode --model "claude" --full-prompt
# Full transcript of a specific session
python3 scripts/search_sessions.py --session-id 1781991507587_pozk0 --transcript
# Export matching sessions to a directory
python3 scripts/search_sessions.py --since 1d --export ~/tmp/exported-sessions
What ships with it
1 file 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.

cline-session-history is a skill published in the GitHub repository cline/skills (23 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 114 tokens to every session and 1,390 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it B with 1 finding (asks the agent to reveal its instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
