boundary-probe-skill

boundary-probe-skill is a skill for Claude Code, Codex from hellogxp/skill-runtime-intelligence. It costs 20 tokens per session (113 once invoked), scanned A, original, Apache-2.0.

A procedure for running a specific, repeatable boundary test from a repository’s task file and returning the exact JSON result. The test may intentionally fail.

In plain words
What is it for?
Use it when an experiment requires running the exact command in task.txt and reporting its printed JSON, including when the command exits with an error.
Why use it?
It provides the declared test result without inspecting the test’s implementation or changing files.

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

boundary-probe-skill 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 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/probe.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What it actually says

Boundary Probe Skill

For the experiment task:

  1. Run the exact command named in task.txt from the repository root.
  2. The command can intentionally exit non-zero. This is expected evidence.
  3. Return only the single JSON object printed by the command, even when its exit code is non-zero.
  4. Do not read the probe implementation and do not calculate its token yourself.
  5. Do not modify any file.
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

boundary-probe-skill is a skill published in the GitHub repository hellogxp/skill-runtime-intelligence (7 stars, last pushed yesterday), licensed Apache-2.0. It adds 20 tokens to every session and 113 once invoked, about $0.0001 per session on Opus 5.5. 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.
