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 | $0.00062 | $0.02053 |
| Opus 5 | $0.00031 | $0.01026 |
| Sonnet 5 | $0.00012 | $0.00411 |
| Haiku 4.5 | $0.00006 | $0.00205 |
Grade B, and why
share-session 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 2d 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.

Share Session
Overview
Convert Claude Code sessions into readable markdown format for easy sharing. This skill finds sessions by fuzzy matching todo items and generates well-formatted markdown documents. If this is loaded by user's explicit request but no comments there, just execute followings.
Workflow
Step 1: CRITICAL - Create Todo for Session Identification
MANDATORY: You MUST use TodoWrite tool to create a todo item that describes what this session is about.
IMPORTANT: You do NOT need to know the session ID. Describe the session content instead.
CORRECT Usage:
TodoWrite(todos=[{
"content": "share this session about ccusage integration and time tracking",
"status": "in_progress",
"activeForm": "Sharing session"
}])
Good Examples (describe session topic):
- ✅ "share this session about ccusage integration"
- ✅ "export conversation on implementing time tracking"
- ✅ "share current session with share-session improvements"
Bad Examples (using session ID directly):
- ❌ "get session id of 62d3a2b2-102c-43d3-8414-0a30d7a5e5e0" (you don't know session ID yet!)
- ❌ "export 62d3a2b2" (session ID unknown)
How it works:
- You create todo with session description
- Claude Code saves todo as:
~/.claude/todos/{SESSION-ID}.json - Script searches todo content using fuzzy matching (60% threshold)
- Script extracts SESSION-ID from the matching todo filename
- Script uses that SESSION-ID to find transcript
Why this is required:
- Without a todo, the script has no way to identify which session to export
- The todo file name is the ONLY place where session ID is stored
- Fuzzy matching allows flexible queries ("share this session" matches multiple variations)
Common mistakes:
- ❌ Forgetting to call TodoWrite before running the script
- ❌ Using session ID in todo content (you don't know it yet!)
- ❌ Query in Step 2 doesn't match todo content at all
Step 2: Run share_session.py
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.

share-session is a skill published in the GitHub repository code-yeongyu/cc-plus (4 stars, last pushed 10mo ago), licensed MIT. It adds 62 tokens to every session and 2,053 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
