From 5c4ed74252be850df28e857947c27ae82d2c2e69 Mon Sep 17 00:00:00 2001 From: karthickmk2001 Date: Wed, 11 Nov 2026 21:18:09 +0000 Subject: [PATCH 1/2] feat(skills): custom skills from user folders, config paths and --skill-file (#79) Load skills from ~/.secfoo/skills, [skills] paths, SECFOO_SKILLS_PATH and secfoo run --skill-file -- never from the scan target. Custom skills may reuse a built-in's output contract and findings lifecycle (output: sast) without ever closing the built-in scan's findings. Malformed or clashing user skills are skipped with a warning naming the files; built-ins still fail hard; user folders reload on mtime change. Adds secfoo skills list/new/validate/show, runs.skill_version/skill_source/skill_sha256 with a migration, a Custom skills sidebar group and picker badge, docs/SKILLS.md, examples/skills/ and a CI validation step.
