Opplan Converter

Documents
opplan-converter

Opplan Converter is an Agent Skill for documents published in the PurpleAILAB/Decepticon repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.

Convert engagement documents into machine-readable OPPLAN for the ralph loop — objective decomposition, acceptance criteria, MITRE mapping, priority ordering.

QUICK START

How to use this skill

Bring this guide into your coding agent with a prompt tailored to the tool you use.

  1. Open your project in Codex.
  2. Copy and paste the prompt below.
  3. Review files and risks before approving any action.
Prompt to paste
Inspect the Agent Skill at https://github.com/PurpleAILAB/Decepticon/blob/HEAD/packages/decepticon/decepticon/skills/standard/soundwave/opplan-converter/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/opplan-converter, but wait for my approval before writing files or running scripts.

Copying this prompt does not install or run the skill. Review third-party files before use.

OPPLAN Converter — CONOPS to Ralph Loop Format

The OPPLAN is the direct analogue of ralph's prd.json — it's the file the autonomous loop reads each iteration to decide what to do next. Each objective must be completable by one agent in one context window.

When to Use

  • After both plan/roe.json and plan/conops.json exist
  • User wants to convert planning docs into executable tasks
  • Starting the autonomous red team loop

Prerequisites

Read both plan/roe.json and plan/conops.json first. The RoE constrains what's allowed; the CONOPS defines the kill chain and threat profile.

See ../references/schema-quick-reference.md for the OPPLAN and Objective schema fields, valid status values, and enum types.

Workflow

Step 1: Extract Kill Chain from CONOPS

Read the CONOPS kill chain phases. Only create objectives for authorized phases.

Step 2: Decompose into Objectives

Each objective must follow the one context window rule — if an agent can't complete it in a single session, it's too big. Split it.

See references/objective-templates.md for recon-phase templates and references/objective-rules.md for the complete decomposition rules.

ID Convention: OBJ-{NUMBER} (auto-generated as OBJ-001, OBJ-002, ...)

post-exploitpostexploitTA0003-TA0009 (Persistence thru Collection)
c2postexploitTA0011 Command and Control
exfiltrationpostexploitTA0010 Exfiltration

Step 3: Write Acceptance Criteria

Every objective MUST have three mandatory criteria types:

  1. Scope check — "All targets verified against plan/roe.json in-scope list"
  2. OPSEC check — At least one OPSEC-related criterion (rate limit, timing, etc.)
  3. Output persistence — "Results saved to /recon/..." (or exploit/, post-exploit/) with specific file path

Beyond these, add criteria specific to what the objective accomplishes. Every criterion must be mechanically verifiable — no vague statements like "good coverage."

Step 4: Assign Metadata

For each objective:

  • priority — Sequential, respects kill chain ordering and dependencies
  • mitre — List of MITRE ATT&CK technique IDs (e.g. ["T1190", "T1059.004"])
  • opsec — OPSEC level: loud, standard, careful, quiet, silent
  • opsec_notes — Specific OPSEC constraints for this objective
  • c2_tier — C2 tier matching OPSEC level: interactive, short-haul, long-haul
  • concessions — Pre-authorized assists if objective is blocked (TIBER/CORIE concept)
  • blocked_by — Objective IDs that must complete first

Step 5: Generate OPPLAN

Use add_objective (one at a time, set engagement_name and threat_profile on first call) → list_objectives to review → present for user approval. No mode switching needed — OPPLAN tools are always available.

Step 6: Validate

See references/objective-rules.md validation checklist before finalizing.

Output

Present a summary table showing all objectives with phase, priority, title, OPSEC level, and MITRE mapping. Wait for user approval before starting execution.
