Guide for creating Claude Code skills following Anthropic's best practices
Safety guardrails for running Claude Code with reduced supervision. The guard-destructive PreToolUse hook matches against a normalized view of each command (heredoc bodies and comments stripped, quoted strings neutralized except interpreter arguments like ssh / sh -c / eval / su / doas), so a command that merely mentions a destructive pattern is not flagged. It hard-blocks catastrophic Bash commands (rm -rf /, rsync --delete, docker volume rm) and makes rm/rmdir scope-aware: operations whose operands all resolve inside the allowed workspace (the session project root, temp dirs, any $GUARD_ALLOWED_EXTRA root, or a variable assigned from a bare mktemp earlier in the same command) run silently, while anything outside it (or any glob/variable/escape it cannot resolve) raises a single reflective confirmation. git reset --hard / clean / restore, shred, dd, mkfs still always prompt.

Independent adversarial honesty reviewer for a DRAFT output: checks claims-vs-evidence (no fabrication, no overreach, no invented IDs) before a human approves. FULL mode reads an agentic-sop-kit run dir's trace; DEGRADED mode reviews any plain document with user-supplied inputs. Deterministic honesty checks in code + a capped ADVISORY adversarial LLM pass. The report is itself a DRAFT — a human owns the verdict; it never auto-approves or auto-rejects. An optional project-scoped Stop-hook can enforce that a human acknowledged a review before the session ends. Not a source-code reviewer.
Claude Code plugin linter + scaffolder. `lint` validates a plugin (or a whole marketplace) against a house grammar — a strict superset of the usual manifest/frontmatter checks plus stdlib-only, hook-protocol, and test-harness invariants; `scaffold` generates a grammar-conformant plugin skeleton that passes the linter by construction. Pure stdlib; self-hosting; runs standalone on any plugin or snaps onto this marketplace.
Deterministic ALCOA+ data-integrity linter for a record/dataset: checks Attributable / Contemporaneous / Complete / Accurate / Consistent in code, and surfaces the human-judgment slice (authorization, gap justification) as a 【待補】 checklist it never auto-concludes. DEGRADED mode lints any CSV/JSON record against a declared contract; FULL mode snaps onto an agentic-sop-kit run dir. The report is a DRAFT — a human owns the verdict. Domain-neutral engine, GMP-flavored ruleset. Pure stdlib.
