What is session-context?

An isolated assistant context for analysing one FullStory session, which is a recorded sequence of a user's interactions with a website or app. It loads the session's event transcript and answers a focused question about it.

Use it to investigate a particular session by providing its device ID, session ID, and a focused question.

It keeps detailed session events separate from the main conversation and directs analysis to one specific task.

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.

Clone the repo

git clone --depth 1 https://github.com/fullstorydev/fullstory-skills

Made for: Claude Code.

Or install fullstory, the plugin that ships this one along with the rest of its 5 skills, 1 agent, 1 MCP server.

Token cost

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	$0.00074	$0.00229
Opus 5.5	$0.00030	$0.00092
Sonnet 5.5	$0.00015	$0.00046
Haiku 4.5	$0.00007	$0.00023

Security

Grade A, and why

session-context 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 15d 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 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.
