detect-tensions

detect-tensions is a skill for Claude Code, Codex from Abilityai/cornelius. It costs 20 tokens per session (967 once invoked), scanned A, original, MIT.

A knowledge-base analysis that finds similar notes with conflicting conclusions. These conflicts can reveal opportunities to combine or rethink ideas.

In plain words
What is it for?
Use it to find tension pairs in a collection of notes and identify subjects for new articles or frameworks.
Why use it?
It helps surface contradictions that are easy to miss when notes are stored separately.

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

detect-tensions 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.

Detect Productive Tensions

ℹ️ First, set expectations: before anything else, print one short line with this skill's version and its most recent change - the top entry of metadata.changelog above - e.g. detect-tensions vX.Y - recent: <summary>. Then proceed.

Scans the knowledge base for productive contradictions: note pairs with high semantic similarity but opposing conclusions. These tension zones are where the most valuable articles and frameworks emerge.

Metadata resources/local-brain-search/data/brain_metadata.pkl Note content

Process

Step 1: Run tension detection

Default thresholds (similarity > 0.75, divergence > 0.3):

cd $PROJECT_ROOT/resources/brain-graph
../local-brain-search/venv/bin/python cli.py tensions

Broader search (more results, lower quality):

../local-brain-search/venv/bin/python cli.py tensions --similarity 0.70 --divergence 0.2

Step 2: Filter false positives, then present synthesis opportunities

The raw count is dominated by false positives - discard them before presenting:

  • Boilerplate / near-duplicate pairs. The signature is high similarity with maximal divergence (e.g. sim ≈ 1.00, divergence ≈ 1.00), and pairs where both notes are changelogs, registries, or near-identical restatements of one principle. These are detector artifacts, not contradictions.

Keep only pairs that assert genuinely opposing conclusions about the same question. For each surviving tension, explain:

  • What the two notes assert
  • Why they contradict
  • What synthesis opportunity exists (article topic, framework potential)

Step 3: Track existing tensions

../local-brain-search/venv/bin/python cli.py status --json

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.

detect-tensions is a skill published in the GitHub repository Abilityai/cornelius (105 stars, last pushed 11d ago), licensed MIT. It adds 20 tokens to every session and 967 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.
