swarm: Skill for Claude Code

.skills/synthesize/SKILL.md

synthesize is a skill for Claude Code from swarm-ai-research/swarm. It costs 63 tokens per session (1,704 once invoked), scanned A, original, MIT.

A workflow for turning an experiment run into structured research notes. It reads run metadata and results, creates an experiment note, checks related claims, and updates the master index.

In plain words
What is it for?
Use it to document one run, batch-process unsynthesized runs, connect findings to existing claims, and maintain a research index.
Why use it?
It prevents experiment findings from remaining as unorganized output that is difficult to compare or reuse.

SkillSpector: 2 findings, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.
    Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.
  • medium Excessive Agency · line 117
    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

synthesize scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 198 lines — stays where its author put it; the contents beside it link to each section on GitHub.

EXECUTE NOW

Target: $ARGUMENTS

Parse immediately:

  • If target is a run_id: synthesize that specific run
  • If target is empty: list recent runs without experiment notes and ask which to synthesize
  • If target is --all: synthesize all runs that lack experiment notes
  • If target is --batch N: synthesize the N most recent unsynthesized runs

Execute steps 0 through 6 in order. Do not ask for confirmation between steps.


Step 0: Validate Target

  1. Check that runs/{run_id}/ exists
  2. Check that runs/{run_id}/run.yaml exists — if not, run python scripts/backfill-run-yaml.py --run-id {run_id} to generate it
  3. Check if vault/experiments/{run_id}.md already exists — if so, report "Already synthesized" and stop (unless --force)

Step 1: Read Run Metadata

Read runs/{run_id}/run.yaml and extract:

  • slug, created_utc
  • experiment.type, experiment.hypothesis, experiment.swept_parameters, experiment.seeds, experiment.total_runs
  • results.status, results.primary_metric, results.primary_result, results.significant_findings
  • artifacts.* — what files are available
  • tags
  • links.claims — any pre-linked claims

If experiment.type is sweep or study, also read the summary JSON file referenced in artifacts.summary.


Step 2: Read Summary Data

Based on experiment.type:

For sweep: Read summary.json. Extract:

  • total_runs, total_hypotheses
  • n_bonferroni_significant or bonferroni_survivors
  • swept_parameters
  • Top 3 most significant results (by effect size)
  • p_hacking_audit

For redteam: Read report.json. Extract:

  • robustness_score, grade
  • attacks_tested, attacks_successful
  • vulnerabilities (critical and high severity)

For study: Read analysis/summary.json or summary.json. Extract:

  • descriptive statistics per condition
  • pairwise_tests — significant comparisons
  • bonferroni_survivors

For single: Read history.json. Extract:

  • Final epoch metrics: welfare, toxicity, acceptance rate
  • Agent-type breakdown if available

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

synthesize is a skill published in the GitHub repository swarm-ai-research/swarm (42 stars, last pushed yesterday), licensed MIT. It adds 63 tokens to every session and 1,704 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
