contradiction-map

contradiction-map is a skill for Claude Code from HirogaKatageri/hirokata. It costs 120 tokens per session (814 once invoked), scanned A, original, MIT.

A method for comparing sources or viewpoints to show where they agree, disagree, or leave important questions unanswered.

In plain words
What is it for?
Use it with research files, articles, reports, or pasted opinions. It can compare existing STORM perspective files or other sets of viewpoints.
Why use it?
It makes conflicts and gaps easier to see instead of hiding them in a summary that suggests false agreement.

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

contradiction-map 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 10d 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.

Contradiction Map — Find Where Understanding Lives

The most valuable understanding lives where credible sources disagree. Consensus is comfortable; contradiction is where the real questions are — and the angle nobody covered is often the gap in the entire field. This skill maps disagreement, agreement, and blind spots across any set of viewpoints. It's STORM Phase 2, usable on its own.

When to Use vs. storm-research

Use this directly when you already have the viewpoints to compare:

  • A prior multi-perspective-scan left a workspace at .storm/{slug}/
  • The user has several documents, reports, or articles to reconcile
  • The user pastes a handful of competing positions and wants them mapped

For generating the perspectives first, then mapping them, use multi-perspective-scan or the full storm-research.

Workflow

Step 1 — Locate the Inputs

Determine what's being compared:

  • STORM workspace: if .storm/{slug}/ exists with perspective files, use those.
  • Files/documents: the user names paths or a directory — gather the relevant files.
  • Pasted viewpoints: the positions are in the conversation — you'll pass them to the agent directly in the prompt.

If the source is unclear, ask one question to pin it down. Establish (or derive) a topic label and, for file-based runs, a workspace .storm/{slug}/ for the output (mkdir -p it).

Step 2 — Spawn the Contradiction Mapper

Launch the contradiction-mapper agent with one Task call:

"Topic: {topic}. Workspace: .storm/{slug}/. Inputs: {list of files, OR the pasted viewpoints inline}. Read every input in full and write .storm/{slug}/contradiction-map.md per your output contract — major contradictions with verdicts, the reliable core of agreement, and the blind spots none of the inputs addressed."

For purely pasted viewpoints with no workspace, instruct the agent to return the map inline instead of writing a file.

Step 3 — Present the Map

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.

contradiction-map is a skill published in the GitHub repository HirogaKatageri/hirokata (5 stars, last pushed 2d ago), licensed MIT. It adds 120 tokens to every session and 814 once invoked, about $0.0006 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 2026-08-31.
