systematic-debugging — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited systematic-debugging (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

<!-- Adapted from obra/superpowers — Tessera graph_impact added to Phase 1 -->
Random fixes waste time and create new bugs. Quick patches mask underlying issues.
Core principle: ALWAYS find root cause before attempting fixes. Symptom fixes are failure.
Violating the letter of this process is violating the spirit of debugging.
NO FIXES WITHOUT ROOT CAUSE INVESTIGATION FIRSTIf you haven't completed Phase 1, you cannot propose fixes.
Before starting Phase 1 — if tessera MCP is configured in this session:
1. graph_continue (mandatory first call)
2. graph_impact(changed_files=["<file where bug was reported>"])graph_impact shows which other files depend on the broken code. This tells you:
Surface this impact map before investigating root cause.
You MUST complete each phase before proceeding to the next.
BEFORE attempting ANY fix:
graph_retrieve(query="<working component similar to broken one>") if tessera MCP is configured to find similar code in the codebasegraph_read to read the working implementation completely, not just skimtest-driven-development skill graph_register_edit(
files = ["path/to/fixed/file::function_name"],
summary = "Fixed: <root cause description>",
checklist_item_id = <id if this maps to an active plan item>
)All of these mean: Return to Phase 1.
| Phase | Key Activities | Success Criteria |
|---|---|---|
| 1. Root Cause | Read errors, reproduce, check changes, gather evidence | Understand WHAT and WHY |
| 2. Pattern | Find working examples, compare | Identify differences |
| 3. Hypothesis | Form theory, test minimally | Confirmed or new hypothesis |
| 4. Implementation | Create test, fix, verify | Bug resolved, tests pass |
