AI code pakka

One disease, three symptoms — wasted tokens, shipped bugs, lost decisions. Pakka treats all three. A small, opinionated harness that wraps Claude Code with compression, gating, and recall.

The treatments

Three primitives.
One harness.

Each command earns its place by removing a category of failure. No flags, no config. Auto-invoked from the conversation when needed.

In session

What you'll actually see.

A request comes in. Pakka quietly chains plan → review → gate. You ship when the gate is green, not when the model says "done."

Recent versions. Each tagged in main, signed, pushed to the marketplace.

most recent first
v0.11.0 2026-06-11 review · guard · bench. performance reviewer (fourth lens); guard learned allowlist + secret-write protection; claude -p A/B bench, no API key; output-tokens re-based. shipped
v0.10.0 2026-06-11 audit hardening. gate-bypass fix, hot-path, accounting + recall/meter fixes. shipped
v0.9.0 2026-06-02 commit-gate. AST parser for chained shapes — git add then commit then push, env prefix, subshells, redirects. Output-token meter monotonic across releases. prior
v0.8.1 2026-06-01 commit-gate. substring fallback no longer rejects non-git bash that mentions "git commit" in quoted arguments. prior
v0.8.0 2026-05-09 orchestrator. user edits to live compressed files survive level changes; snapshot refresh failure aborts pass instead of overwriting. prior
v0.7.0 2026-05-09 validator. ten fixes across validator, meter, recall, report — single-char identifiers, env vars, semver suffixes preserved. prior
