Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • gmem.diff

    Show how memory state changed between two points in time. Accepts ISO 8601 timestamps OR git commit refs (HEAD, HEAD~3, branch names, full or short SHAs) — refs are resolved via `git show -s --format=%cI` in the active project root. v0.5 milestone.

  • gmem.ingest_agent_activity

    Pull Solana activity for an autonomous-agent wallet via Helius RPC, aggregate it (txCount, distinct peers, failure ratio, age, sanctioned-neighbor count), score it with the transparent v1 heuristic, and write one Agent entity per (cluster, pubkey). Use `fixturePath` to run offline against a snapshot; otherwise set HELIUS_API_KEY or pass `apiKey`. v1.2 milestone — the missing trust layer for agent-to-agent payments.

  • gmem.ingest_anchor

    Auto-ingest an Anchor workspace: parses `Anchor.toml`, captures the IDL SHA-256 for each program from `target/idl/<name>.json`, and records the current git HEAD as the source commit. Writes one Program entity per (program, cluster) pair. v0.3 milestone.

  • gmem.ingest_hardhat

    Auto-ingest a Hardhat (EVM) workspace: walks up to the nearest hardhat.config.{ts,js,cjs,mjs}, reads every deployment artifact under deployments/<network>/<Contract>.json (hardhat-deploy convention), classifies the network into a canonical chain id, computes a stable ABI sha256, records git HEAD as sourceCommit. Writes one Contract entity per (chain, address). v1.1 milestone. Companion to gmem.ingest_anchor for Solana.

  • gmem.list_decisions

    List all Decision entries for the active project, newest first.

  • gmem.recall

    Retrieve memory entries relevant to a natural-language query for the active Solana project. Ranked by BM25 over entity fields with a recency boost.

  • gmem.score_agent

    Look up the latest stored Agent entity for (cluster, pubkey) and return its trust score with the heuristic breakdown showing which factors moved it. Read-only: does not call Helius or write a new version — use gmem.ingest_agent_activity for that. v1.2 milestone.

  • gmem.solana_context

    Read the active Solana CLI context (`~/.config/solana/cli/config.yml`) and return the configured cluster, RPC URL, and the public address of the active keypair. Used to auto-attribute Decision writes to a developer wallet. v0.4 milestone. Does not return the secret key.

  • gmem.write

    Persist a typed memory entry (Program / Account / Instruction / Decision / Finding / Integration). Append-only: re-writing the same logical entity creates a new version, never overwrites.
