Resolve one correctness-blocking external or version-specific technical uncertainty through bounded investigation. Use when cheap local inspection cannot establish framework, library, tool, runtime, protocol, or platform behavior needed by the current task.
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
# Technical Spike Own extended technical investigation while the calling workflow retains its planning, implementation, or validation decision. ## Workflow 1. State the exact question, applicable versions, decision it blocks, and stopping condition. 2. Check local manifests, lockfiles, configuration, code, tests, installed versions, and command help first. 3. When local evidence is insufficient, use the most authoritative relevant primary source: official documentation, specifications, upstream source, release notes, or a bounded reproduction. 4. Read public documentation and upstream source when the host allows network access, and never put private repository or customer data in a query. Require explicit authority before dependency changes, repository edits, external writes, or experiments with side effects. Keep temporary reproductions outside the repository unless the task authorizes a durable test. 5. Separate observed facts from inference and record only conclusions that affect the current task. 6. Translate evidence into concrete design, compatibility, implementation, or verification implications. …

How to install
mdr add yarlson/yarstack/technical-spike@sha256:1ed44c97ca934232The line at the top of this page pins the label git:20261017.2f2e03b, 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.
