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.

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 | $0.00040 | $0.00953 |
| Opus 5.5 | $0.00016 | $0.00381 |
| Sonnet 5.5 | $0.00008 | $0.00191 |
| Haiku 4.5 | $0.00004 | $0.00095 |
Grade A, and why
session-review 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 7d 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 — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Session review
Start with the session map, narrow to relevant events, and inspect the screen only when needed.
MCP tools
| Goal | Tool |
|---|---|
| Read a transcript without opening a session | fullstory:review-summary |
Open a session and get its map, first event slice, and client_id |
fullstory:review-open |
| Read a time window with detail chosen per event kind | fullstory:review-zoom |
| Capture a screenshot, component tree, or both at a timestamp | fullstory:review-snapshot |
| Release the open session's resources | fullstory:review-close |
For transcript-only questions, use review-summary in an isolated context. It needs neither client_id nor cleanup. For multi-moment visual inspection, delegate to the session-replay agent to keep images out of the main context. If the client cannot load agents, use its isolated-task mechanism with the same workflow.
Workflow
1. Choose the lightest entry point
Use fullstory:review-summary when a transcript answers the question. Otherwise:
fullstory:review-open(session_url="https://app.fullstory.com/ui/<org-id>/session/<device-id>:<session-id>")
Pass the whole URL as session_url. session_id is only the session part and requires device_id. Other supported selectors are trace_id, trace_url, email_address, and user_uid. Use the tool's advertised schema for the selector you have.
The open response contains the session map (span, flow, and event counts), an initial event slice, and client_id. The initial slice is not the complete session.
2. Narrow to key moments
Use the map to locate relevant navigations, clicks, frustration signals, custom events, console errors, and network requests. Read the relevant window:
fullstory:review-zoom(client_id="<id>", t0_ms=<start_ms>, t1_ms=<end_ms>)
Choose detail per event kind using the live tool schema: request full error detail, standard network detail, and summarize unrelated events. Do not invent parameter names for detail controls. Follow returned coverage information rather than treating an omitted event as evidence it never happened.
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-review is a skill published in the GitHub repository reatlat/fullstory-claude-plugin (35 stars, last pushed 7d ago), licensed MIT. It adds 40 tokens to every session and 953 once invoked, about $0.0002 per session on Opus 5.5. 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.
