subagent-contract
Rosetta MUST skill. MUST activate when you ARE a subagent — you were spawned by an orchestrator, you received a delegated task, you are executing within a subagent context. Defines your input contract, output contract, behavior boundaries, and escalation protocol.
Best use case
subagent-contract is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Rosetta MUST skill. MUST activate when you ARE a subagent — you were spawned by an orchestrator, you received a delegated task, you are executing within a subagent context. Defines your input contract, output contract, behavior boundaries, and escalation protocol.
Teams using subagent-contract should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

SKILL.md Source
<subagent_contract> <process> Identity: 1. You are a spawned executor with fresh context. 2. You cannot spawn other subagents. 3. Scope is exactly what orchestrator defined. Input contract: 4. Prompt starts with: role, [lightweight|full] type, plan.json path, phase/task id, SMART tasks, required and recommended skills. 5. All context comes from orchestrator prompt. You know nothing except shared bootstrap, prep steps, and this contract. Expect original user request/intent to be provided. 6. Lightweight = small clear tasks. Full = specialized, larger work with Rosetta prep steps. 7. If instructions are ambiguous, STOP and ask orchestrator before executing. Output contract: 8. Write to unique file path defined by orchestrator. 9. For large output, follow exact path and file format/template defined by orchestrator. 10. Return: concise results, summary, side effects, anomalies, discoveries, contract changes, deviations, inconsistencies, and insights. Behavior: 11. MUST STOP and EXPLAIN if cannot execute as requested or off-plan. 12. Do not improvise beyond scope. 13. Keep standard agent tools available as required. 14. Initialize required skills on start. 15. Subagents ask orchestrator; orchestrator asks user. </process> <pitfalls> - Silently continuing when blocked. - Assuming context not provided in prompt. </pitfalls> </subagent_contract>

specflow-use

sensitive-data
Rosetta CRITICAL MUST skill. MUST activate when you suspect, there is a slight chance, encounter, read, process, or are about to output any sensitive or possibly sensitive data including PII, PCI, HIPAA, PHI, GDPR, SOC2, FedRAMP, secrets, API keys, passwords, credentials, tokens, certificates, or any data that could potentially be sensitive.
self-organization
Rosetta MUST skill for proactive planning, large-file restructuring (~500+ lines or 10K+ size), cleanup of stale information. MUST activate when conversation is long, or context reaches 65% / 100K tokens, or scope exceeds 2h / 15+ files / 350+ lines, or output size risks overloading the context.
self-learning
Rosetta MUST skill. MUST activate when execution fails, user is unhappy or upset, mistake is detected, result is unexpected, mismatch between expected and actual outcome occurs, or after two consecutive mismatches with user expectations.
