All notable changes to this project will be documented in this file.
- Clarified proportional rigor as a cross-cutting constraint rather than a thirteenth principle or a mandatory tier system.
- Added the smallest-decision-changing evidence rule and an explicit stop condition for additional validation.
- Clarified that user-reported symptoms are high-value evidence while proposed causes remain hypotheses to verify independently.
- Added source-backed evidence from invocation economics, fail-fast and early-exit workflows, hard/soft dependency policy, YAGNI architecture scoping, pruning, and fact/decision boundaries.
- Synchronized the English source documents, Chinese mirrors, installable skill, evidence boundary, case study, repository-engineering guide, notice, and plugin metadata.
- Added the source README's “Skills for Real Engineers” framing and its four engineering failure themes to the English and Chinese READMEs.
- Added a source-backed repository-engineering study covering lifecycle, manifests, harness metadata, configuration adapters, human documentation, Changesets, and release automation.
- Added a dedicated deprecated/in-progress evolution study with recorded-versus-interpreted labels.
- Added a separate Skill Creator Pro case study covering the OpenAI baseline, independent extensions, three real-skill studies, release evidence, and limitations.
- Extended the methodology, evidence map, examples, single-file guidelines, and installable skill with a conditional repository-engineering branch.
- Documented that the Matt source snapshot contains no Python compilation gate, repository-wide
validator, universal lint/test suite, or numeric
SKILL.mdlimit. - Updated Claude plugin and marketplace metadata to version 1.1.0.
- Added a dependency-free repository validator, four regression tests, and Windows/Linux validation CI for the study repository's own release contract.
- Published the twelve Matt Pocock-inspired skill-writing principles.
- Added English and Simplified Chinese README, methodology, evidence map, and examples.
- Added a single-file guideline and an installable Agent Skill.
- Pinned every source claim to
mattpocock/skills@66898f6and documented interpretation boundaries.
