probe

probe is a skill for Claude Code from pantheon-org/tekhne. It costs 69 tokens per session (2,222 once invoked), scanned A, a copy of probe, MIT.

A two-stage method for testing a hypothesis in a complex situation through a small, low-risk experiment and then interpreting what happened.

In plain words
What is it for?
Use it to try a safe experiment, check its result, and decide what to investigate or change next.
Why use it?
It helps reveal useful patterns when cause and effect are not clear in advance.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: model in frontmatter; names the AskUserQuestion tool; mentions Claude Code.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./scripts/run-query-benchmarks.sh --env staging --compare main.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

probe 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 5d 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.

Origin

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.

Probe

Safe-to-fail experiment in Complex domain. Cause-effect only visible in retrospect — probe to sense patterns, not to prove.

Probing: $ARGUMENTS

Check for handoff context: if $ARGUMENTS references a probe-to-probe-llm.md file, load it before Phase 1 — carried context accelerates qualification.

⚠️ AskUserQuestion Guard

CRITICAL: After EVERY AskUserQuestion call, check if answers are empty/blank. Known Claude Code bug: outside Plan Mode, AskUserQuestion silently returns empty answers without showing UI.

If answers are empty: DO NOT proceed with assumptions. Instead:

  1. Output: "⚠️ Questions didn't display (known Claude Code bug outside Plan Mode)."
  2. Present the options as a numbered text list and ask user to reply with their choice number.
  3. WAIT for user reply before continuing.

Phase 1: Qualify (foreground — MANDATORY)

ENTRY GATE: Phase 2 does not start until Phase 1 is complete. No bypass path exists.

1.1 Parse hypothesis

Extract from $ARGUMENTS or handoff context:

  • Hypothesis statement (what you believe might be true)
  • Enabling constraints already known (carry forward from prior cycles — do NOT rediscover)
  • Confirm/refute criteria already defined (carry forward, update if refined)

If no hypothesis present: AskUserQuestion — ask user to state the hypothesis. Do not proceed without one.

1.2 Identify enabling constraints

Bounds without prescribing path:

  • Scope: time, access, reversibility boundary
  • Immutable: production systems, data integrity, user-facing state
  • Variable: what can be freely changed within experiment

Carry forward from prior cycles unchanged unless explicitly updated.

1.3 Define confirm/refute criteria

Before running: define observable signals. For each criterion:

  • Confirmed: observable evidence that supports the hypothesis
  • Refuted: observable evidence that contradicts the hypothesis
  • Surprise: unexpected result that suggests a different hypothesis

Criteria must be defined before Phase 2 executes. Gate on this.

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.

probe is a skill published in the GitHub repository pantheon-org/tekhne (10 stars, last pushed today), licensed MIT. It adds 69 tokens to every session and 2,222 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 89% identical to probe, differing in 94 lines, and is treated as a copy.
