PROFILE
Feist Josselin
Josselin Feist contributed to the crytic/slither repository by delivering features that enhanced code quality, documentation, and static analysis capabilities. He improved the call graph printer’s formatting using Python and Black, ensuring consistent Graphviz DOT output for better maintainability. Josselin advanced Slither’s analysis of Solidity smart contracts by refining SSA generation and storage pointer tracking, addressing Yul assembly’s sstore/sload operations for more accurate vulnerability detection. He overhauled documentation structure and CI workflows, optimizing onboarding and build reliability. His work demonstrated depth in code refactoring, technical writing, and CI/CD configuration, resulting in a more robust and developer-friendly analysis toolchain.

Mar 1, 20252025-03 monthly summary for crytic/slither highlighting delivered features, fixes, impact, and skills demonstrated. Key features delivered include a comprehensive Documentation overhaul with clearer navigation, dedicated tool docs, standardized links/naming, and wording improvements across README, SUMMARY, and tool docs to enhance user experience. CI and docs quality improvements were implemented by excluding docs from markdownlint checks and tightening workflows to reliably reflect repository structure and tooling usage, with small README/workflow adjustments to prevent CI issues. Major bugs fixed revolve around CI workflow reliability and linting-related false positives, achieved by adjusting lint rules and workflows. Overall impact includes improved onboarding, reduced CI churn, more reliable builds, and clearer guidance for tool usage, contributing to higher developer productivity and faster user adoption. Technologies and skills demonstrated include documentation engineering, CI/CD optimization, markdownlint customization, and GitHub Actions workflow hygiene.
