CEG — AppWorld Hidden-API Discovery Benchmark

Benchmark specification for the hidden-API discovery setting used in the CEG project (Observation-Verified Partial-Skill Memory for Training-Free LLM Agents).

A set of advanced-feature APIs is removed from the agent's documentation (their existence, signature, and docs are redacted) while they remain executable, forcing a frozen agent to (i) discover each capability from its own observations and (ii) use it reliably to complete multi-requirement AppWorld tasks.

This repo ships the selection spec, not raw task content. The actual AppWorld tasks come from the appworld Python package (pip install appworld); these files tell you which tasks to run and which APIs to hide.

Contents

appworld_hidden_api/
  config_13api/        # main paper set — 48 tasks, 13 hidden APIs
    hidden_apis.json   #   {"hard": [ 13 fully-qualified API names to redact ]}
    task_ids.json      #   [ 48 AppWorld task ids ]  (16 templates × 3 variations)
    task_meta.json     #   task_id -> {"split": ..., "gold_hidden": [APIs the gold solution calls]}
  config_30api/        # larger variant — 75 tasks, 30 hidden APIs (same schema)

How the sets were built (reward-free, no hardcoding)

1. Pool AppWorld tasks across train+dev splits.
2. Keep a task only if its ground-truth solution genuinely calls one of the hidden APIs (recorded per task in task_meta.json["gold_hidden"]) — so discovery is required, not optional.
3. The hidden APIs are non-basic "new-feature" actions (e.g. spotify.follow_artist, spotify.add_to_queue, venmo.remind_payment_request, file_system.compress_directory); each app's authentication, reads (show_/list_/search_), and primary create/send/play actions stay visible.

Usage

import json
hidden = json.load(open("appworld_hidden_api/config_13api/hidden_apis.json"))["hard"]
task_ids = json.load(open("appworld_hidden_api/config_13api/task_ids.json"))
# Run each task_id in AppWorld while redacting `hidden` from the API catalog
# (show_api_descriptions / show_api_doc / search_api_docs) but keeping them CALLABLE.

The 13-API config is the headline benchmark; official Task Goal Completion (TGC) is the metric.
