reap-02-feature-tracing-any-program SKILL.md skillA
reap-02-feature-tracing-any-program from joasasantos/rea-prompts is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

REA prompt pack: Feature tracing (any program) (3 ready-to-paste prompts). Use when doing reverse-engineering investigation of feature tracing (any program) with REA (rea.tools) via an AI coding agent.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# REAP — 2. Feature tracing (any program) Part of REAP (REA Investigation Prompts). Replace everything in <angle brackets>; keep each request focused on one feature. Demand file/function/address evidence and separate facts from hypotheses. ### Explain one feature ```text Use REA to investigate how <FEATURE> works in <PATH TO APPLICATION>. Identify the entry point, the functions involved, the data flow, the dependencies and the observable effects. For every conclusion, present evidence: file, function, address or relevant snippet. Separate confirmed facts, inferences and points that remain unknown. Do not execute the application in this step. ``` ### Trace a button to its effect ```text Use REA on <app>. Start at the <button name> button and trace what happens until the result is written, sent or shown. Name every module or function on the path and what each one does. ``` ### Recover a rule and rebuild it ```text Use REA to find the rule that controls <behaviour> in <program>. Write the rule in plain words, then build a minimal standalone version I can run, and give me one input that proves it matches the original. ``` ---

How to install
mdr add joasasantos/rea-prompts/reap-02-feature-tracing-any-program@sha256:e9919b65ccd2e7dfThe line at the top of this page pins the label git:20261025.9bd45a8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
