Patinate
Render Strava activity into stylized heatmap posters and inline SVG. A single Rust binary keeps a SQLite activity cache, draws it over an OpenStreetMap basemap in one of four baked-in themes, trims every track inside a privacy circle before render, and can strip identifying attributes on the way out. The patina builds where you ride often: overlapping low-alpha strokes accumulate into brighter color the way actual patina builds on metal.

jig
An agent-shape harness that points a real agent at a real CLI and counts what happens: a battery declared in agent-shape.toml, a headless runtime spawned against the fixture, and an LLM judge scoring the transcript on a 4-point scale whose top mark is a first command that was real and worked. A companion check guards the rubric against drift in the tool's own help output.

kit
A tool-registry manager that resolved developer tool versions across git-based TOML registries, generated mise configuration from the result, and verified every install against a per-tool trust tier, from cosign down to a bare checksum. Three CI pipelines proposed and gated the bumps until mise covered the same ground.

rune
A Rust CLI that treated a git repository as the canonical home for an agent's skills, subagents, and rules, syncing them into each project's .claude directory behind a content-hash lockfile and a write hook that surfaced drift in the same turn as the edit. Retired once the portable SKILL.md layout made most of what it did a directory of markdown and a symlink.

The Hunt for Leverage
On test frameworks that tell agents what to do next, and the design patterns that make LLM-generated tests actually correct.

muxr
Harness session multiplexer for AI coding workflows. Owns the harness/campaign/session/segment address across tmux, the filesystem, and your AI runtime so a rename stays coherent in all three.

kebnf
Converts the OMG's KeBNF text for KerML and SysML v2 into ANTLR4 and tree-sitter grammars from one AST, all 640 rules, recording the metamodel annotations it strips. A mechanically faithful tree-sitter emitter timed out parsing a one-line file; inlining shared prefix keywords took it to 0.15ms and cut LR conflicts from 335+ to 199.

sysml
A single Rust binary that parses SysML v2 models into a queryable knowledge graph, exposed through a clap CLI for humans and CI and a stdio MCP server for agents, both over the same core. The open question is whether the CLI is the cheaper transport for an agent, and I have not measured it yet.

sysml-bench
An evaluation harness asking whether giving a tool-augmented LLM more tools actually helps it answer questions about a SysML v2 engineering model. 88 tasks scored per field against published schemas, run across four tool sets and six public corpora, with a pre-registered replication whose frozen hypothesis did not survive the independent corpus.

synthesist
A Rust CLI that records the process governing a body of code (what was planned, what was agreed, what phase the work is in) as an append-only claim graph an agent can query instead of inferring from a diff. Workflow state is a per-asserter JSON-LD log read back through a disposable index, under a phase machine that forbids every write until a human approves the plan.
