synthesize

synthesize is a command for coding agents from lhl/realitycheck. It costs 11 tokens per session (693 once invoked), scanned A, original, Apache-2.0.

A cross-source analysis tool that combines findings from separate source reviews into one conclusion. It compares where sources agree, disagree, and remain uncertain.

In plain words
What is it for?
Use it to answer a defined question using existing source analyses, identify gaps, and write a linked synthesis document.
Why use it?
It removes the need to manually reconcile several research notes and track which sources support each claim.

Command

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Part of the reality plugin — 8 commands, 2 hooks shipped together

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add commands/lhl/realitycheck/synthesize
Clone the repo
git clone --depth 1 https://github.com/lhl/realitycheck

Or install reality, the plugin that ships this one along with the rest of its 8 commands, 2 hooks.

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 4d 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.

/reality:synthesize - Cross-Source Synthesis

Create a cross-source synthesis across multiple source analyses and existing claims.

Use this after running /reality:check on multiple sources (or when relevant source analyses already exist and you want a higher-level conclusion).

Usage

/reality:synthesize <topic>

Output

Write a synthesis document to: analysis/syntheses/<synth-id>.md

The synthesis should link back to relevant source analyses in: analysis/sources/<source-id>.md

Workflow

  1. Define the question
    • What is this synthesis trying to answer?
  2. Collect inputs
    • Prefer existing source analyses in analysis/sources/
    • If a relevant source has no analysis yet, run /reality:check first (or explicitly record the gap)
  3. Write the synthesis
    • Points of agreement (which claims converge?)
    • Points of disagreement (where do they conflict, and why?)
    • Conclusions with calibrated credence + key uncertainties
    • Link claim IDs and source analysis files wherever possible
  4. Neutral Analyst Prose Pass
    • Apply this pass to the analyst's prose, not source text, direct quotes, titles, quoted slogans, or persuasion/rhetoric examples.
    • Remove rhetorical setup, marketing language, vague intensifiers, hedge stacks, and conclusion recaps from analyst prose.
    • Preserve source wording when it is evidence for rhetoric, framing, or persuasion; label it as source language instead of adopting it as the analyst's voice.
  5. (Optional) Register an argument chain
    • If the synthesis centers on a specific argument chain, register it and point --analysis-file at the synthesis document:
"${CLAUDE_PLUGIN_ROOT}/scripts/run-db.sh" chain add \
  --id "CHAIN-YYYY-NNN" \
  --name "..." \
  --thesis "..." \
  --claims "TECH-2026-001,ECON-2026-002" \
  --analysis-file "analysis/syntheses/<synth-id>.md"
  1. Validate
"${CLAUDE_PLUGIN_ROOT}/scripts/run-validate.sh"
  1. Update README
    • Add a row to the "Syntheses" table (kept above "Source Analyses") in your data repo README.md.
  2. Commit and push
    • If you ran a DB write command (e.g., chain add), the plugin hook may auto-commit.
    • Otherwise, commit your analysis/ + README.md changes manually.

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 command published in the GitHub repository lhl/realitycheck (41 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 11 tokens to every session and 693 once invoked, about $0.0001 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 2026-08-30.
