GitHub post attribution (shared)

Skills that post content to GitHub should append a small footer: link to the invoking skill's SKILL.md at the current agents commit (the revision in use when the post was made), plus the model name that executed the skill.

When to use

• Any gh command that creates or updates issue/PR text visible on GitHub.
• Invoked by name from other skills (e.g. "follow skills/github-post-attribution/SKILL.md before posting").

Resolve repository root, commit, and GitHub base URL

REPO_ROOT = the directory that contains skills/ (the agents checkout). The path to this file is always known from the Read call that loaded it. Use it directly -- no additional filesystem exploration needed.

Every skill file lives at <REPO_ROOT>/skills/<SKILL_DIR>/SKILL.md. Resolve symlinks (e.g. ~/.agents/skills → ~/src/agents/skills) and capture all values in one call:

SKILL_MD_DIR=$(dirname "$(readlink -f /path/to/this/SKILL.md)")
REPO_ROOT=$(cd "$SKILL_MD_DIR" && git rev-parse --show-toplevel)
SKILL_COMMIT=$(cd "$REPO_ROOT" && git rev-parse HEAD)
SKILL_SHORT_SHA=${SKILL_COMMIT:0:7}
REMOTE_URL=$(cd "$REPO_ROOT" && git remote get-url origin)

Replace /path/to/this/SKILL.md with the absolute path used in the Read call. readlink -f resolves any symlinks before git sees the path, so --show-toplevel always returns the real repo root.

From REMOTE_URL, normalize to https://github.com/{owner}/{repo}:

• [email protected]:owner/repo.git → https://github.com/owner/repo
• https://github.com/owner/repo.git → https://github.com/owner/repo

Call that {BASE}.

Resolve model name

The model that executed the skill is identified by its short name (e.g. glm-5.1, claude-sonnet-4-20250514). The agent knows its own model at runtime from its environment. Set MODEL_NAME to the model's human-facing label:

MODEL_NAME="glm-5.1"  # replace with the actual model name at runtime
