stable v0.4 embeddingsdeduplicationmemoryllmgeminicloudflare-ai-gateway

Semantic deduplication for zeitgeist drafts. Compares each topic section of a candidate zeitgeist memory against the N most-recent stored zeitgeists using Gemini embeddings (via Cloudflare AI Gateway) and emits a delta-only compressed version.

Scopes

compute.llm-inference read, write cf-api-token (coarse; full AI Gateway access)

Each check_delta call sends the candidate draft and N prior memory sections to Gemini's text-embedding model, consuming tokens against the user's Cloudflare AI Gateway quota. Cost is variable in candidate length × N.
memory.tracking read turso-libsql-token (coarse; full DB access)

Reads the N most-recent `zeitgeist`-tagged memories from Turso to compare against. Read-only; the tool returns a delta but does not write it back — the caller decides whether to store.
net.outbound read, write gateway.ai.cloudflare.com, *.turso.io

Talks to gateway.ai.cloudflare.com (which forwards to Gemini's embedding endpoint) and to the configured Turso libSQL host for memory reads.

Actions

Compare a candidate zeitgeist draft against recent stored zeitgeists and return per-section duplicate flags plus a compressed delta-only version. · compute.llm-inference memory.tracking net.outbound

Goal

Identify which sections of a candidate zeitgeist memory duplicate prior entries, and emit a compressed delta.

Inputs

draft (req markdown), n_recent (int, default 5), threshold (float, default 0.85)

Outputs

{report: [{section, verdict, similarity, ref_id?}], delta_text: string, total_sections: int, redundant_count: int}

Errors

tracking_unconfigured, gateway_unreachable, embed_failed, draft_empty

Example

check_delta draft='# Topic A\n...' n_recent=5 threshold=0.85

Environment

`CF_ACCOUNT_ID`	Cloudflare account ID hosting the AI Gateway used to proxy Gemini embedding calls. The tool routes through Cloudflare for caching, observability, and rate-limit pooling. required · secret: no
`CF_GATEWAY_ID`	Cloudflare AI Gateway slug — the gateway name chosen when it was created in the Cloudflare dashboard. required · secret: no
`CF_API_TOKEN`	Cloudflare API token scoped to AI Gateway access. Treat as a secret. Required. required · secret: yes
`TURSO_TOKEN`	Turso libSQL auth token for the Muninn memory database. The tool reads recent zeitgeist memories to compare against. Required. required · secret: yes · obtain
`TURSO_URL`	Hostname of the Muninn memory libSQL database, e.g. 'mydb-username.turso.io'. required · secret: no

Runtime

runtime: python-module · install method: preinstalled · entrypoint: python -m muninn_utils.zeitgeist_delta

Reads recent `zeitgeist`-tagged memories from Turso, splits the candidate draft into topic sections by markdown header, embeds each section + each prior memory's sections via Gemini's text-embedding model (proxied through Cloudflare AI Gateway), and computes cosine similarity. Sections above a duplicate threshold are flagged as redundant; the rest pass through into a compressed delta-only version that can be stored without bloating the memory store. Like `verify_patch` (LLM-as-judge with Anthropic + optional Turso writes) but with embeddings instead of completions and a different cloud surface (Cloudflare AI Gateway → Gemini, not Anthropic). Issue #5 calls this out as the test for whether two LLM-as-judge tools share a manifest pattern.
