| description | Router to ECC LIBRARY skills for this Rust library crate. Use when a task needs an off-stack ECC skill that is turned OFF by default (any language other than Rust, frontend/web, database, cloud/infra, networking, ML, agent-harness meta, domain/business ops). Names the relevant skill so it can be invoked directly with the Skill tool. |
Skill Library (mmap-guard)
This repo is a pure Rust library crate (the safe mmap boundary). Only a lean
DAILY set of ECC skills loads by default; everything else is turned OFF in
.claude/settings.local.json to keep context clean.
OFF does not mean deleted. Every skill below is still installed and can be
invoked on demand with the Skill tool (e.g. Skill(skill="ecc:docker-patterns")).
This router exists so those skills remain discoverable by keyword.
DAILY (already loaded — no router needed)
rust-patterns, rust-testing — the crate itselfgit-workflow, github-ops — commits, PRs, mergify, release-plz, ghsecurity-review — the unsafe boundary this crate encapsulates
LIBRARY — invoke on demand by keyword
Rust adjacent (ordered by relevance to this crate)
- memory safety / the unsafe boundary →
systems-programming:memory-safety-patterns — the crate's whole reason to exist; reach for it before touching the single unsafe block in src/map.rs
- error handling on the failure paths →
ecc:error-handling — the value proposition is returning io::Error gracefully instead of crashing: empty file, concurrent truncation (SIGBUS), permission denied, advisory-lock WouldBlock
- TDD discipline →
ecc:tdd-workflow — the repo mandates write-tests-first; the proptest suites and fuzz/ targets that harden the boundary live under the DAILY rust-testing
- security audit / bounty →
ecc:security-bounty-hunter, ecc:security-scan, ecc:safety-guard
- benchmark / perf →
ecc:benchmark, ecc:benchmark-methodology, ecc:latency-critical-systems, ecc:data-throughput-accelerator
- architecture decisions →
ecc:architecture-decision-records
- codebase onboarding / tour →
ecc:codebase-onboarding, ecc:code-tour, ecc:repo-scan
- coding standards →
ecc:coding-standards (marginal — the pedantic/nursery clippy config in Cargo.toml already enforces most of this in-repo)
No serde, clap, tokio, thiserror, or async in this crate (deps are just
memmap2 + fs4), so the Rust library skills for those are noise here.

python, django, fastapi, laravel/php, golang, java/springboot/quarkus, kotlin,
swift/swiftui, cpp, csharp/dotnet, fsharp, perl, ruby, react/vue/nuxt/angular,
dart/flutter → ecc:<lang>-patterns, ecc:<lang>-testing, ecc:<lang>-security.
Web / frontend / design
ecc:frontend-patterns, ecc:frontend-a11y, ecc:design-system,
ecc:motion-foundations / ecc:motion-advanced, ecc:accessibility,
ecc:make-interfaces-feel-better, ecc:taste.
Data / infra / cloud

ecc:mongodb, ecc:prisma-patterns, ecc:database-migrations,
ecc:docker-patterns, ecc:kubernetes-patterns, ecc:deployment-patterns,
ecc:clickhouse-io.
Networking / homelab
ecc:cisco-ios-patterns, ecc:netmiko-ssh-automation,
ecc:network-bgp-diagnostics, ecc:network-config-validation,
ecc:homelab-*.
Agent / harness / meta (ECC internals)
ecc:configure-ecc, ecc:ecc-guide, ecc:skill-scout, ecc:skill-stocktake,
ecc:agent-sort, ecc:continuous-learning-v2, ecc:context-budget,
ecc:strategic-compact, ecc:eval-harness, ecc:autonomous-loops.
Domain / business ops
healthcare, finance/billing, logistics/ito/carrier, marketing/brand/seo,
scientific databases, blockchain/defi, video/media — search the OFF list in
.claude/settings.local.json and invoke ecc:<name> directly.
Re-promoting a skill to DAILY
If a LIBRARY skill becomes routine, flip its value from "off" to "on"
(or remove the entry) in .claude/settings.local.json → skillOverrides.
