Interface: SessionSummarizerOptions

Defined in: packages/agentos/src/memory/ingest/SessionSummarizer.ts:81

Options for constructing a SessionSummarizer.

Properties

cacheDir?

optional cacheDir: string

Defined in: packages/agentos/src/memory/ingest/SessionSummarizer.ts:89

Optional directory for persistent disk cache. When set, summaries survive across process restarts and re-runs. Mirrors the CachedEmbedder cache layout.

---

invoker

invoker: SessionSummarizerInvoker

Defined in: packages/agentos/src/memory/ingest/SessionSummarizer.ts:83

LLM invoker — produces the summary text.

---

maxTokens?

optional maxTokens: number

Defined in: packages/agentos/src/memory/ingest/SessionSummarizer.ts:100

Maximum tokens to ask the LLM to emit. Default 140 (generous headroom over the 50–100 target; truncate post-hoc if needed).

---

modelId

modelId: string

Defined in: packages/agentos/src/memory/ingest/SessionSummarizer.ts:95

Model identifier baked into the cache key so switching models invalidates the cache automatically. Should match the invoker's underlying model.

---

onCallCost()?

optional onCallCost: (tokensIn, tokensOut, model) => void

Defined in: packages/agentos/src/memory/ingest/SessionSummarizer.ts:108

Optional cost-tracker hook. Called after every uncached call.

Parameters

tokensIn

number

tokensOut

number

model

string

Returns

void

---

templateVersion?

optional templateVersion: string

Defined in: packages/agentos/src/memory/ingest/SessionSummarizer.ts:106

Template version. Bump whenever the summarization prompt changes so disk caches from prior versions are invalidated. Current: 'v1-2026-04-19'.
