compare — Same-Epoch Training Run Comparison
Compares training runs across wandb, neptune, mlflow, or tensorboard by aligning them at the same training step instead of current-vs-final.

What it does
- Auto-detects your experiment tracker from env vars and directories (wandb, neptune, mlflow, tensorboard, local JSON results).
- Pulls the full metric history rather than only the final summary value.
- Finds the in-progress run's current step and slices the baseline at that same step, killing the classic "epoch 11 vs epoch 100" error.
- Separates proxy metrics (kNN top-1, loss, perplexity) from downstream targets (linear probe, task F1) and reports them in a compact table.
- Enforces full run names, flags single-seed comparisons, and warns about metrics logged inconsistently across runs.
Who it's for
- ML researchers and engineers tracking many concurrent training runs against a baseline
- Grad students who repeatedly build experiment comparison tables for papers
- Anyone who gets asked "is this run winning?" mid-training
Examples
- "Is my running fastvit experiment catching up to the conv baseline?" → fetches both histories, slices at the current epoch, prints a delta table.
- "Rank the 5 runs in this sweep" → aligns all at a common step, ranks proxy and downstream separately, notes single-seed caveats.
- "Has my run converged?" → shows the last five epochs of the curve instead of asserting a winner prematurely.

Try it now, no install
Paste this into Claude to use the skill without installing anything.
Read the instructions in this file and follow them to help me: https://raw.githubusercontent.com/fcakyon/phd-skills/HEAD/plugin/skills/compare/SKILL.md What I want: (describe your task here)
If Claude can't open the link, open it yourself and paste the contents instead.
↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.
Install in the Claude app (no terminal)
- Download the ZIP with the button below.
- In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
- Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
Install in Claude Code
Let Claude do it — paste this into Claude Code
Install the skill I found on Claude Skill Mart. Copy the plugin/skills/compare folder from the GitHub repo fcakyon/phd-skills into my ~/.claude/skills/compare/. When it's done, tell me in one line what this skill can do.
Install with a command instead
git clone https://github.com/fcakyon/phd-skills.git && mkdir -p ~/.claude/skills && cp -r phd-skills/plugin/skills/compare ~/.claude/skills/⚠ This is a third-party skill. Check the source repository before installing.
- Open a terminal.
- Clone the repository:
git clone https://github.com/fcakyon/phd-skills.git - Create the skills directory:
mkdir -p ~/.claude/skills - Copy the skill:
cp -r phd-skills/plugin/skills/compare ~/.claude/skills/ - Restart Claude Code and try a prompt like "compare my wandb run to the baseline".
- Prerequisites: set your tracker credentials (
WANDB_API_KEY,NEPTUNE_API_TOKEN,MLFLOW_TRACKING_URI) and install the matching Python client before running comparisons.
