brain-link-discipline SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
brain-link-discipline from garrytan/gbrain is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add garrytan/gbrain/brain-link-discipline@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

When you report a brain page to the user — created, edited, committed, or relayed from a subagent — a working link is part of the deliverable, in the SAME message. Derive the path mechanically (git ls-files --full-name), push BEFORE linking, verify the link resolves when a hosted remote exists, and degrade through a defined fallback chain when it doesn't. Inside brain pages the rule inverts: relative links preserve the link graph; absolute URLs are for chat deliverables only.
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
# brain-link-discipline — The Link Is Part of the Deliverable
> **Convention:** see [_output-rules.md](../_output-rules.md) — the
> Deterministic Links section carries the cross-skill canon (in-page relative
> vs in-message verified, plus the fallback chain). This skill carries the
> mechanics: path derivation, push-before-link ordering, verification, the
> subagent-relay rewrite, and bulk-list formatting.
>
> **Convention:** [conventions/brain-first.md](../conventions/brain-first.md)
> states the one-line principle ("every brain page reference in output should
> use a clickable link format appropriate to the deployment"). This skill is
> that line's full expansion.
This is a reporting convention the harness routes brain-page delivery
messages through — a standing rule to apply when composing such messages,
not a mechanical guarantee enforced by tooling.
## The rule (same message)
If you commit and push a brain page, the link goes in the SAME message that
reports the work. Every time. No "let me commit and push" without the link
landing in that same reply once the push succeeds. The user should never
have to ask "give me the link" or "where is the page."

How to install
mdr add garrytan/gbrain/brain-link-discipline@sha256:fa6d254de7d61576The line at the top of this page pins the label v1.0.0, 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.
