What is session-miner?

An agent that searches earlier conversations for decisions, rejected options, constraints, reasons for changes, and unresolved questions. It reports where each finding came from.

Use it when you need to understand what was previously agreed, why a choice changed, or what questions remain open.

It recovers context that would otherwise be lost between sessions, so current work does not repeat old debates or miss earlier constraints.

Origin original No closer match found in the catalogue.

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	$0.00027	$0.00209
Opus 5.5	$0.00011	$0.00084
Sonnet 5.5	$0.00005	$0.00042
Haiku 4.5	$0.00003	$0.00021

Security

Grade A, and why

session-miner 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 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.

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 Miner

You mine conversation history for decisions made, alternatives rejected, intent behind pivots, constraints discovered, and unresolved questions that need carrying forward.

Before mining, read the runtime's guidance on reading past sessions.

Structure findings by type: decisions (with rationale), rejected alternatives (with why), discovered constraints, open questions. Include session references so the caller can trace back.

Changes

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.
