steve 95f564ac4e P4: contrib/store — second module (pure-Go SQLite), budget store
Establish the nested persistence module — the architectural reason the core
stays lean: a SEPARATE go.mod carrying modernc.org/sqlite (pure Go, no cgo), so
the SQLite driver NEVER enters the executus core go.sum. A static-binary host
(gadfly) importing only the core stays static; a host wanting turnkey
persistence imports contrib/store.

- sqlite.go: store.Open(dsn) -> *DB (one SQLite file), accessor-per-seam.
- budget_store.go: db.Budget() satisfies budget.BudgetStorage; Add() does the
  7-day window rollover atomically inside a transaction (concurrent Adds can't
  race the read-modify-write — the in-memory store's one weak spot).
- Conformance test: budget.NewDBBudget over the SQLite store passes the SAME
  rolling-window contract as the in-memory store.
- CI: a new step builds + tests contrib/store on its own AND asserts it carries
  the sqlite driver the core forbids (proof the split works). Verified: core
  go.sum has 0 sqlite refs; contrib/store go.sum has it.

persona/skill/audit SQLite stores follow next (same JSON-blob + indexed-columns
pattern, sidestepping the three-layer field-loss footgun).

Raw Blame History

executus

⚠️ This project is vibe-coded. executus is written almost entirely by an AI coding agent (Claude), with a human steering at the design and review level rather than typing the code. That's a deliberate choice, stated up front — the same way gadfly is. Read the code before you depend on it, pin a version, and file issues if something looks off. It is offered as-is.

A batteries-included base for building LLM agent harnesses in Go. Import it, do a little wiring, and you have agentic capabilities: a bounded run loop, a tool registry with a suite of common tools, context compaction, config-driven model tiering and failover, structured output, and parallel fan-out — with sensible defaults so a brand-new project is agentic with almost no setup, and pluggable seams so a serious host can swap in its own storage, config, delivery, and tools.

executus sits strictly above majordomo — the lean LLM substrate (agent loop, canonical llm types, providers, media normalization, model parsing / failover / tiering). majordomo stays the substrate; executus is the opinionated, batteries-included layer on top. executus requires no changes to majordomo.

Status

Early. Being extracted, phase by phase, from the agent layer of mort (a Discord bot) — mort and gadfly are the first two consumers (heavy and light). See CLAUDE.md for the architecture and the extraction roadmap (P0P6).

Available today:

  • run/executus is runnable. run.Executor ties model resolution, the tool registry, majordomo's agent loop, context compaction, run-bounding, and step/audit instrumentation into one Run(ctx, RunnableAgent, inv) Result, with every host concern behind a nil-safe run.Ports (Audit/Budget/Critic/ Checkpointer/PaletteSource/Delivery). See examples/minimal.
  • model/ — config-driven tier resolution + failover over majordomo, with pluggable UsageSink/TraceSink and GenerateWith[T] structured output.
  • tool/ — the tool registry + 3-stage permission model + SSRF guard.
  • compact/ — the per-run context compactor.
  • lane/ — bounded worker pool with fair-share queueing (run- and provider-concurrency).
  • fanout/ — programmatic N×M swarm with bounded global + per-key concurrency.
  • config/, deliver/, identity/ — host seams (config / output / identity), each with a shipped default.
  • dispatchguard/, pendingattach/ — run-safety primitives.

Design

Two tiers in one module (go.mod = majordomo + stdlib only):

  • Core — everything a light host needs to be agentic: run loop, tool registry + common tools, model resolution, compaction, lanes, fan-out, structured output. No persistence, no scheduling.
  • Batteries (opt-in sibling packages) — persona/agent nouns, saved skills, audit, run-critic, scheduling, budgets, checkpointing. Each is nil-safe and ships a default, so you add only what you use.

Persistence that needs a real database lives in a separate nested module (contrib/store, pure-Go SQLite — the budget store landed first, conformance-tested) so the core never drags in a DB driver — a static-binary host (gadfly) stays static.
