Creates and improves a plugin's chain contract (agents/_chain-permitted.yaml) to the Advanced Skill Library Standard. Use when a skill or subagent invokes another component and you need to declare the permitted inter-component invocations, or to resolve S4 orphan or phantom findings.
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
# askit-build-chain-contract ## Purpose Author a plugin's chain contract: the explicit declaration of which components may invoke which others (Standard sec 3.6). A chain contract is a CONDITIONAL MUST - required if and only if a component invokes another, so a plugin with no inter-component invocation ships no contract (no empty governance files). Two modes: `create` authors `agents/_chain-permitted.yaml` (and the optional `agents/_pairing.yaml`); `improve` resolves S4 findings. Authoring depth is in [references/authoring-chain-contracts.md](references/authoring-chain-contracts.md). Follows the shared builder contract ([../../docs/reference/builder-pattern.md](../../docs/reference/builder-pattern.md)). ## When to use When a skill or subagent declares a `chain:` to another component and you need to permit it, or when `evaluate` reports an S4 orphan (an invocation not permitted) or phantom (a contract entry naming a missing component). ## create mode 1. Scan components for `chain:` declarations (which caller invokes which callees). Skip the contract entirely if nothing chains (the conditional MUST). …

How to install
mdr add product-on-purpose/agent-skills-toolkit/askit-build-chain-contract@sha256:0dd9bfb1ac2e75f1The line at the top of this page pins the label v0.1.0, 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.
