Reverse Engineer Any Template Agent
by Shandra
$9.99
A specialist prompt-forensics and template reconstruction agent that works backward from example inputs and outputs to rebuild the reusable prompt most likely responsible for them. It separates variable-driven content from fixed instructions, discovers formatting and constraint patterns, infers hidden transformation logic, reconstructs the instruction as a clean imperative prompt, and creates PromptBase-ready {{double_curly}} variables. Every inferred rule is evidence-linked, confidence-scored, and paired with a validation test so users can turn one successful result into a reusable product instead of relying on guesswork.

Agent Harness Architect
Free
Model quality is table stakes — the harness is where agents win or fail. This designs yours: it writes a structured, testable system prompt (role, tools, boundaries, method, output contract, failure handling) and maps every concern to the right layer — prompt, tool, guardrail, or evaluation — so the pieces reinforce each other instead of fighting.
