subagent-driven-development — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited subagent-driven-development (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.

Execute plan by dispatching fresh subagent per task, with two-stage review after each: spec compliance review first, then code quality review.
Core principle: Fresh subagent per task + two-stage review = high quality, fast iteration.
Continuous execution: Do not pause between tasks unless BLOCKED, genuinely ambiguous, or all tasks complete.
Use when you have a written implementation plan with independent tasks and want to stay in the current session. For parallel-session execution, use executing-plans instead.
At the start of each dispatch round (before dispatching any subagent) — if tessera MCP is configured:
1. graph_continue (mandatory first call for the coordinator too)
2. graph_retrieve with the current task's key termsThis keeps the coordinator's routing accurate as files change during execution.
Every implementer subagent prompt you dispatch MUST include these instructions:
Tessera graph policy (if tessera MCP is configured in this session):
1. Call graph_continue as your FIRST tool call
2. Call graph_retrieve with this task's key terms
3. Read all recommended_files via graph_read before exploring
4. After each file edit, call graph_register_edit with file::symbol notation
- If graph_continue returned an active_checklist, include the checklist_item_id
for the task you just completed
5. Call graph_lock_decision when you make an architectural choiceThis ensures Tessera's compliance tracker stays updated as each subagent works.
git diff HEAD~1)graph_register_edit marks the checklist item doneIf tessera MCP is configured: run tessera-verify to confirm plan compliance before finishing.
All checklist items done? → tessera-verify passes → proceed
Missing items? → complete them firstThen invoke finishing-a-development-branch skill.

[Exact test commands and expected output]
**Tessera graph policy (if tessera MCP is configured):**
- Call graph_continue as your FIRST tool call
- Read recommended_files via graph_read
- After each edit: graph_register_edit(files=["file::symbol"], summary="...")
