Before you rent the GPUs, check the map: hardware inventory, memory math, and dated engine-support matrix to pick the right LLM serving engine.

The 2-second pre-merge gate for AI-assisted diffs: complexity, duplication and growth checks on changed code only. No model, no account, no network.
sessguard: local, read-only, zero-network CLI that inventories AI-assistant session and credential material on your machine and gives you a per-app revocation checklist. Never prints token values.
Measure your app across installed JS runtimes and get an upgrade verdict with reasons.
A local, deterministic, read-only behavioral detector for the Gheist planted-workflow attack shape: one command, one verdict per repository, one rotate checklist. No model, no account, no secret values ever printed.
A local, deterministic pre-execution gate for software an agent is about to install.
A deterministic diet for agent context: shrink logs, outputs, and repeated turns with an exact manifest. No model, no network, nothing invented.
Find the first real error in a failed CI log, tell flaky tests apart from real breakage, and cluster repeat failures. Zero dependencies.
Vendor-neutral policy, evidence and credential layer for AI agents: deterministic policy decisions outside the model process, a tamper-evident action ledger, and coverage accounting that fails loudly when an action leaves no record.
Open vendor-neutral DevSecOps operating layer: reference architecture, policy-as-code packs, CI security gates and audit-evidence automation for regulated organisations.
Audit .env files: drift vs .env.example, placeholders, risky secrets, unused vars. Zero dependencies.
Audit Agent Skills packs: duplicates, overlapping triggers, missing metadata. Zero dependencies.
Trim verbose logs and tool output to a token budget — keep the errors, drop the noise. Zero dependencies.
Catch tests that lie: fake passes, retry loops, swallowed assertions, deleted tests — Python + JS/TS, zero dependencies.
Scan a project for things that will break or leak: deprecated deps, EOL runtimes, unpinned CI actions, over-broad permissions, unpinned Docker bases, removed APIs. Zero dependencies.
Map where your API keys actually live — local, read-only auditor for agent-tool configs. Never prints key material, never sends anything anywhere.
Decision memory with provenance: record decisions, facts and constraints as a graph, trace why anything was decided, and catch contradictions and stale dependencies.
Will this GGUF model actually fit your GPU? Offline, zero-dependency VRAM check — weights + KV cache vs your card, in one command.
Approval leases for agent-run commands — approvals that expire by construction.
Check the numbers in AI-generated prose against their cited sources — zero-dependency Python CLI.
Shrink JSON for LLM prompts by folding long keys into short aliases — lossless, reversible, with a receipt.
How to use a tool
- Open the tool on GitHub for install + run + expected output (env-doctor also has a tool page).
- Clone from GitHub — code is never gated.
- Report bugs on GitHub Issues. For hands-on help, see deployment help.
