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 | $0.00050 | $0.00421 |
| Opus 5 | $0.00025 | $0.00211 |
| Sonnet 5 | $0.00010 | $0.00084 |
| Haiku 4.5 | $0.00005 | $0.00042 |
Grade A, and why
session-detail 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 4d 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.
What it actually says
Session Detail
Show comprehensive details about a single session.
Step 1: Get session detail
bun run ${CLAUDE_PLUGIN_ROOT}/lib/session-store.ts session-detail <session-id>
This returns: session summary, token usage (input/output/cache), models used, tools called, and associated task lists with their tasks.
Step 2: Present summary
Show a formatted summary:
- Session: ID, project, date, duration
- Tokens: input, output, cache read, cache create
- Models: which models were used and how many turns each
- Tools: top tools used with counts
- Tasks: associated task lists and task status summary
Note on resumed sessions
If is_resumed is true in the stats, this session was started via claude --resume or claude --continue. The JSONL only contains messages from the resumed portion — earlier context from the parent session is not included. Mention this to the user so they understand why the transcript may appear to start mid-conversation.
Step 3: Show messages (optional)
If the user wants to see the conversation:
bun run ${CLAUDE_PLUGIN_ROOT}/lib/session-parser.ts messages <session-path> --limit 20
For more messages, increase --offset and --limit:
bun run ${CLAUDE_PLUGIN_ROOT}/lib/session-parser.ts messages <session-path> --offset 20 --limit 20
To include tool call details:
bun run ${CLAUDE_PLUGIN_ROOT}/lib/session-parser.ts messages <session-path> --include-tools --limit 20
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.

session-detail is a skill published in the GitHub repository apappascs/claude-code-sessions (4 stars, last pushed 3mo ago), licensed MIT. It adds 50 tokens to every session and 421 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 2026-08-31.
