Refresh Agent Skills is an agent skill from wcygan/dotfiles. Refresh the pinned wcygan/agent-skills catalog for this dotfiles checkout, install it into Codex user scope, verify every skill and path, and optionally commit and push the update. Use when asked to update, refresh, reinstall, reconcile, or publish the project's agent skills.
Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows. The repository describes itself as: Configuration for Development Environments. The licence is MIT.
7 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit b385ffa. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
gitmakeghpython3uvFrom the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
github.comFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Refresh Agent Skills loads about 2.4k tokens when it runs. Until then it costs about 74 tokens; SKILL.md has 668 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
The full file from wcygan/dotfiles at commit b385ffa, republished under its MIT licence (© wcygan). 668 words, ~2,441 tokens.
.claude/skills/refresh-agent-skills/SKILL.md (or your agent's skills folder).Update the repository's pinned reusable-skill catalog and reconcile the local Codex installation. Keep wcygan/agent-skills as the source of truth and use the dotfiles bootstrap command as the only consumer-side installer.
The task is complete only when all of these are true:
Start with repository and provider status. The provider checkout is useful for review, but it is not a second source or installation implementation.
git status --short
git -C ../agent-skills status --short 2>/dev/null || true
sed -n '1,40p' agent-skills.lock.toml
gh skill list --dir "$HOME/.agents/skills" \
--json skillName,sourceURL,scope,version,pinned,pathResolve origin/main from the live GitHub remote on every run. Do not use the
local ../agent-skills checkout, its current branch, or the existing lock as
the latest-version oracle:
remote_refs="$(git ls-remote \
https://github.com/wcygan/agent-skills.git refs/heads/main)" || exit
if [ "$(printf '%s\n' "$remote_refs" | awk 'NF == 2 { count++ } END { print count + 0 }')" -ne 1 ]; then
printf '%s\n' "expected exactly one origin/main ref" >&2
exit 1
fi
latest_sha="$(printf '%s\n' "$remote_refs" | awk 'NR == 1 { print $1 }')"
if ! printf '%s\n' "$latest_sha" | grep -Eq '^[0-9a-f]{40}$'; then
printf '%s\n' "origin/main did not return a full lowercase SHA" >&2
exit 1
fi
printf '%s\n' "$latest_sha"Require exactly one 40-character lowercase hexadecimal SHA from that command.
If the remote cannot be resolved, or returns no or multiple refs, stop and
report the network/authentication failure. Do not guess a tag, branch, or
abbreviated SHA. If the locked commit equals latest_sha, keep the lock
unchanged and continue with install/reconcile. Otherwise replace the lock with
latest_sha before discovering or installing the catalog.
Review the provider delta before pinning when a provider checkout is present:
git -C ../agent-skills diff --stat \
"$(sed -n 's/^commit = "\([0-9a-f]\{40\}\)"$/\1/p' agent-skills.lock.toml)..$latest_sha"
git -C ../agent-skills log --oneline --decorate \
"$(sed -n 's/^commit = "\([0-9a-f]\{40\}\)"$/\1/p' agent-skills.lock.toml)..$latest_sha"Use apply_patch to replace only the commit = "..." line in agent-skills.lock.toml. If tests/test_agent_skills.py contains a hard-coded fixture commit, update that fixture to the same full SHA; do not alter the test's behavior or other files.
Then inspect the diff:
git diff -- agent-skills.lock.toml tests/test_agent_skills.py
git diff --checkThe bootstrap installer rejects duplicate or foreign-source collisions. Before using it, inspect the current inventory and, when possible, compare it with the provider tree:
gh skill list --dir "$HOME/.agents/skills" \
--json skillName,sourceURL,scope,version,pinned,path
find ../agent-skills/skills -mindepth 2 -maxdepth 2 -name SKILL.md \
-print 2>/dev/null | sortgh skill install does not prove that removed upstream skills are pruned. If the provider tree is available, identify installed names absent from that tree and report them. Do not delete them automatically; removal is a separate user-authorized cleanup.
Run the focused, journaled mutation only:
./bootstrap.sh agent-skillsRecord the reported catalog count and the actual destination. The expected
command uses --dir "$HOME/.agents/skills" --all --pin <full-sha> internally;
do not replace it with a clone, copy, symlink, or direct write to the shared
directory.
Run both the strict read-only check and the Make target:
./bootstrap.sh agent-skills --check
make agent-skills-checkRun this normalized audit so timestamps in GitHub CLI tracking state cannot mask an inventory or metadata problem:
python3 - <<'PY'
import json
import subprocess
from pathlib import Path
import tomllib
with open("agent-skills.lock.toml", "rb") as f:
lock = tomllib.load(f)
inventory = json.loads(subprocess.check_output([
"gh", "skill", "list", "--dir",
str(Path.home() / lock["directory"]),
"--json", "skillName,sourceURL,scope,version,pinned,path",
], text=True))
names = [item["skillName"] for item in inventory]
assert len(names) == len(set(names)), "duplicate installed skill names"
assert {item["sourceURL"] for item in inventory} == {
f"https://github.com/{lock['repository']}"
}
assert {item["scope"] for item in inventory} == {"custom"}
assert {item["version"] for item in inventory} == {lock["commit"]}
assert all(item["pinned"] is True for item in inventory)
parents = {str(Path(item["path"]).resolve().parent) for item in inventory}
assert len(parents) == 1, parents
print(f"verified {len(inventory)} skills at {next(iter(parents))}")
PYIf the provider checkout is available, validate its source as an additional provider-side check:
for skill_dir in ../agent-skills/skills/*; do
[ -f "$skill_dir/SKILL.md" ] || continue
uv tool run --from skills-ref agentskills validate "$skill_dir" || exit 1
done
gh skill publish --dry-runWarnings from the provider's dry run are reportable; validation errors are blocking.

./bootstrap.sh recoverrecover must report that no interrupted dotfiles operation needs recovery. Linux, Docker, or evaluation-only results do not establish macOS acceptance; record the actual platform used.
When the user explicitly requested commit/push, first confirm the diff contains only the lock/test expectation and this skill. Stage paths explicitly:

git diff --cached --check
git diff --cached --stat
git commit -m "chore(skills): refresh pinned agent skills"
git push origin "$(git branch --show-current)"If the pin was unchanged and the skill file is the only change, use a concise skill-specific commit subject instead. Do not create an empty commit. After a successful push, report the commit SHA, branch, provider SHA, catalog count, destination, checks, stale-name review, and any provider warnings.

Refresh the pinned wcygan/agent-skills catalog for this dotfiles checkout, install it into Codex user scope, verify every skill and path, and optionally commit and push the update.
Refresh Agent Skills fits situations like: asked to update; publish the projects agent skills.
Run `npx skills add wcygan/dotfiles --skill refresh-agent-skills -a claude-code`. Or copy the skill folder (.agents/skills/refresh-agent-skills in wcygan/dotfiles) into .claude/skills/refresh-agent-skills in your project. Claude Code loads it when a task matches its description.
Run `npx skills add wcygan/dotfiles --skill refresh-agent-skills -a codex`. Or copy the skill folder (.agents/skills/refresh-agent-skills in wcygan/dotfiles) into .agents/skills/refresh-agent-skills in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add wcygan/dotfiles --skill refresh-agent-skills -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/refresh-agent-skills, .gemini/skills/refresh-agent-skills, .github/skills/refresh-agent-skills and .opencode/skills/refresh-agent-skills in your project.
Going by SKILL.md and its folder, Refresh Agent Skills needs the command-line tools its instructions call (git, make, gh, python3 and uv). Our summary lists: Python 3; Docker.
SKILL.md names 1 domain. In commands or code: github.com; the agent is likely to contact it when it follows the instructions. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Refresh Agent Skills is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.4k tokens (SKILL.md is roughly 9.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Refresh Agent Skills: MCP Server Builder (anthropics/skills, 180k stars), Hook Development for Claude Code Plugins (anthropics/claude-plugins-official, 38k stars), Using Superpowers (farm-fe/farm, 5.6k stars) and Executing Plans Inline (obra/superpowers, 297k stars).
