footprint SKILL.md skillA

footprint from footprintjs/footprint is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add footprintjs/footprint/footprint@git:20261106.259c0a5

Pins git:20261106.259c0a5 in mdr.lock. Pin the fingerprint instead.

Use when building flowchart pipelines with footprintjs: stages, decide and select branches, subflows, loops, retries, $call and $attempt, time budgets, pause and resume, recorders, narrative, redaction, contracts, saved records and foottrace queries. Also use when someone asks how FootPrint works or wants to understand the library.

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

# FootPrint: connected runtime logs for people and AI agents

<!-- Generated from ai-instructions/source by scripts/ai-instructions/generate.mjs. Edit the source, then run npm run ai:generate. -->

## Which copy to trust

This skill is a copy and can lag. `node_modules/footprintjs/AGENTS.md` holds the same text for the installed version, so trust it over this file.

## What FootPrint is

**Connected runtime logs for people and AI agents.**

FootPrint runs your logic as a flowchart of named stages. While it runs, it records what each stage read and wrote, which decision was taken and why, and every retry. No model is involved and nothing is rebuilt afterwards. A person or an agent follows a result back through the record instead of guessing from separate log lines.

The one law: collect during the run, and never walk the tree afterwards. Evidence that was not collected stays unknown. The record shows what the program did, not whether it was right.

## How a chart runs

- **Build:** `flowChart<T>()` starts a chart. `.addFunction()` and the branch methods add stages. `.build()` fixes its shape.

How to install

The exact contents, by fingerprint
mdr add footprintjs/footprint/footprint@sha256:de9edbd1ae1f0256

The line at the top of this page pins the label git:20261106.259c0a5, 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.
