implement-mainspec

Implements a mainspec end-to-end by auto-detecting mode. Sequential mode (≤3 slices) commits slices in order on the current `feature/<feature>` branch. Parallel mode (>3 slices) uses dependency-aware tiered execution with per-slice worktrees, branches, PRs, and auto-merge into the feature branch. Agent-first — invoked headless by the harness dispatcher with the feature slug as its single argument. No human-in-the-loop, no approval gates.

Critical

E006: Malicious code pattern detected in skill scripts.

What this means

Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.

Why it was flagged

The skill enables fully automated, agent-driven code changes with elevated subagent privileges ("bypassPermissions"), automatic execution of repo-provided bootstrap scripts, and unattended creation/auto-merge/push of branches to origin with no human approval — a clear enabler for supply-chain/backdoor insertion, remote code execution, and unauthorized code/data exfiltration.

Medium

W013: Attempt to modify system services in skill instructions.

What this means

The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.

Why it was flagged

The skill explicitly instructs spawning subagents with mode "bypassPermissions" (an instruction to bypass security/permission controls) and performs automatic repository and remote state changes (git worktrees, commits, pushes, PR creation and auto-merges) with no approval gates, which together indicate a high risk of compromising the machine or environment state.
