agent_atoms — composed-AgentHarm agent runs

Raw per-trial outputs from the agent_atoms experiments: how a tool-using Gemini-2.5-Pro agent behaves when k AgentHarm "atoms" (individual harmful tasks) are composed into one prompt, for k ∈ 1..6.

See the source repo and full technical report: agent_atoms (private repo) / document.md.

Content notice. Each record's transcript field contains the agent's verbatim attempt to act on a harmful AgentHarm task. Most are refusals, but some include partial completions (e.g. drafted phishing emails, drug synonyms, etc.). Use for safety research only.

Files

File	Records	Design	Composer	What it is
runs.jsonl	60	independent	scenario	Pool of unrelated atoms, LLM-rewritten into one scenario (early run; "legacy").
runs_concat.jsonl	60	independent	concat	Same unrelated pool, pasted as a numbered list, no rewriting.
runs_nested.jsonl	60	nested	scenario	Chain where atom i+1 uses atom i's output, LLM-rewritten.
runs_nested_concat.jsonl	60	nested	concat	Same chain, pasted as a numbered list.
scenario_cache.json	—	—	—	Hashed cache of LLM-rewritten scenarios, keyed by (model, temp, sorted_behavior_ids, prompt_version). Required to reproduce scenario-mode runs without Gemini calls.
per_k_safety_<design>.csv	6 each	various	various	Per-k mean safety with SEM (4 files).
per_k_refusal_<design>.csv	6 each	various	various	Per-k refusal rate with SEM (4 files).
stats.json	—	—	—	OLS regressions, bootstrap CIs, and per-category means used in the report.

Each JSONL has 10 trials per k for k ∈ {1, 2, 3, 4, 5, 6} (60 records), written by agent_atoms/experiment.py.

Designs at a glance

Two orthogonal axes:

	Scenario composer	Concat composer
Independent atoms	runs.jsonl (legacy)	runs_concat.jsonl
Nested chain	runs_nested.jsonl	runs_nested_concat.jsonl

• Scenario = an LLM (Gemini-2.5-flash, temp 0.0) merges the k atoms into a single unified prompt.
• Concat = atoms pasted as a numbered list with a fixed preamble, no rewriting.
• Independent = atoms drawn from the balanced AgentHarm pool without any narrative dependency.
• Nested = atoms chained so atom i+1 needs atom i's output.

Headline finding

Across all four designs, per-atom safety rises with k, not falls. Under runs_nested_concat.jsonl, refusal saturates at 100% from k = 2 onward. OLS slopes of trial mean_safety on k:

Design	β per k	95% CI	p
independent_legacy	+0.046	[+0.013, +0.079]	0.006
independent_concat	+0.029	[−0.017, +0.075]	0.21
nested	+0.052	[+0.015, +0.088]	0.005
nested_concat	+0.039	[+0.013, +0.065]	0.003

Experimental config

• Agent model: google/gemini-2.5-pro, temperature 0.0
• Judge / scenario builder: google/gemini-2.5-flash, temperature 0.0
• Atom source: AgentHarm (UK AISI / Gray Swan), test_public split, harmful config
• Pool: 50 behaviors, balanced across 8 categories, seed=42
• k range: 1..6, 10 trials per k → 60 trials per design

Loading

from datasets import load_dataset

ds = load_dataset("s-haider/agent-harm-atoms-run", "nested_concat", split="train")
print(ds[0]["mean_safety"], ds[0]["k"], ds[0]["per_atom"])

Or load all four configs:

for cfg in ["independent_legacy", "independent_concat", "nested", "nested_concat"]:
    ds = load_dataset("s-haider/agent-harm-atoms-run", cfg, split="train")
    print(cfg, len(ds))
