Twin of probe-allowed-tools whose allowed-tools value is a bare lowercase shell tool name, as some platforms spell it. Use when asked to probe allowed-tools lowercase naming.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Allowed-Tools Naming Probe (Lowercase Twin) The spec's experimental `allowed-tools` field is "a space-separated string of tools that are pre-approved to run," but it leaves tool names to each platform, and platforms spell their shell tool differently. This twin declares the bare lowercase spelling one platform uses for its shell tool, then asks for the same printf as `probe-allowed-tools`, so testers can see whether the field's effect depends on matching the platform's own tool name. This body deliberately never spells out the field's literal value. ## Canary Phrase The canary phrase for this skill's body is: **STILT-SCORIA-5526** ## Instructions When activated: 1. Report: "probe-allowed-tools-lowercase activated. Canary: **STILT-SCORIA-5526**" 2. Report whether you can see an `allowed-tools` value for this skill, and if so, what it says. 3. Run exactly this command and report its output verbatim, or the exact error if it was blocked: `printf 'CHOUGH-%s-7180\n' 'TUFA'` 4. Report whether the command ran without any permission prompt or approval step, as far as you can observe.

How to install
mdr add agent-ecosystem/agent-skill-implementation/probe-allowed-tools-lowercase@sha256:32bbc6d1284000e8The line at the top of this page pins the label git:20260926.cb3708f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
