Common skills scripts

These scripts help consuming repositories install, remove, and verify shared agent skills from warpdotdev/common-skills.

Files

• resolve_common_skills: resolves and executes scripts from this directory, a local override directory, or raw GitHub.
• install_common_skills: installs or updates common skills, then verifies the installed contents.
• update_common_skills_lock: regenerates an existing common-skills lockfile without installing skills.
• remove_common_skills: removes installed common skills from a selected target.

Quick start

Install common skills into the current checkout:

scripts/install_common_skills --project

Install common skills globally:

scripts/install_common_skills --global

Install only when the lock hash has changed or a locked skill is missing:

scripts/install_common_skills --project --if-needed --non-interactive

Verify the installed skills without installing:

scripts/install_common_skills --verify-only

Remove installed common skills:

scripts/remove_common_skills --project

Invoking from client repositories

Client repositories do not need to vendor these scripts. They should keep a small script/resolve_common_skills shim that loads this repository's scripts/resolve_common_skills and forwards arguments to it. For example, a client repo's script/resolve_common_skills shim can look like this:

#!/usr/bin/env bash

set -eo pipefail

COMMON_SKILLS_REPO="warpdotdev/common-skills"
COMMON_SKILLS_REF="${WARP_COMMON_SKILLS_REF:-main}"
RAW_BASE_URL="${WARP_COMMON_SKILLS_RAW_BASE_URL:-https://raw.githubusercontent.com/${COMMON_SKILLS_REPO}/${COMMON_SKILLS_REF}/scripts}"

if [[ -n "${WARP_COMMON_SKILLS_SCRIPTS_DIR:-}" ]]; then
  exec "${WARP_COMMON_SKILLS_SCRIPTS_DIR%/}/resolve_common_skills" "$@"
fi

curl -fsSL "${RAW_BASE_URL%/}/resolve_common_skills" | bash -s -- "$@"

The shim's default path executes this repository's shared resolver through curl:

curl -fsSL "https://raw.githubusercontent.com/warpdotdev/common-skills/${WARP_COMMON_SKILLS_REF:-main}/scripts/resolve_common_skills" | bash -s -- install_common_skills -- --repo-root "${REPO_ROOT}" --if-needed --prompt-for-target

Consumer bootstrap and run scripts call the shim instead of calling curl directly:

./script/resolve_common_skills install_common_skills -- --repo-root "${REPO_ROOT}" --if-needed --prompt-for-target

With an explicit target, client repos pass the same installer flags they would pass locally:

./script/resolve_common_skills install_common_skills -- --repo-root "${REPO_ROOT}" --global --if-needed
./script/resolve_common_skills install_common_skills -- --repo-root "${REPO_ROOT}" --project --force

The resolver supports these development overrides:

• WARP_COMMON_SKILLS_REF=<git-ref>: fetch scripts from a branch, tag, or commit in warpdotdev/common-skills; also forwarded to the installer so missing-lock creation and interactive lock update checks use the same ref.
• WARP_COMMON_SKILLS_SCRIPTS_DIR=/path/to/common-skills/scripts: execute scripts from a local checkout or worktree instead of fetching from GitHub.
• WARP_COMMON_SKILLS_RAW_BASE_URL=https://...: override the raw URL base used by the resolver.

Developing against these scripts from a client repo

For normal client-repo development, test the remote path first:

WARP_COMMON_SKILLS_REF=<your-common-skills-branch> ./script/bootstrap --install-common-skills-globally
WARP_COMMON_SKILLS_REF=<your-common-skills-branch> ./script/run --install-common-skills

Use WARP_COMMON_SKILLS_SCRIPTS_DIR when iterating on unpushed local script changes:

WARP_COMMON_SKILLS_SCRIPTS_DIR=/path/to/common-skills/scripts ./script/run --install-common-skills

Client repos should keep their own skills-lock.json checked in. Normal install flows use that lock as the source of truth; interactive flows may ask to update it when this repo would produce a different lock. Review and commit lock changes in the client repo separately from changes to this repo.

Install script

install_common_skills installs common agent skills from warpdotdev/common-skills. When skills-lock.json is missing, the script creates it by running the skills CLI against the source repo and selecting all valid skills. This is intentionally dynamic: the script should not hardcode a fixed list of common skill names. Set WARP_COMMON_SKILLS_REF=<git-ref> to create the lock from a branch, tag, or commit such as warpdotdev/common-skills#my-branch. When skills-lock.json already exists and the script is running interactively, it checks whether warpdotdev/common-skills would produce an updated lock before prompting for a project/global install target. If WARP_COMMON_SKILLS_REF is set, the check uses that branch, tag, or commit as the candidate source. If a different lock is available, it asks before updating skills-lock.json and reinstalling from the updated lock. Non-interactive and verify-only runs skip this upstream update prompt and use the existing lock. When skills-lock.json already exists, the script installs from the lock file:

• Project target: npx --yes skills@1.5.6 experimental_install
• Global target: npx --yes skills@1.5.6 add warpdotdev/common-skills --global --agent warp --skill <locked skills> --yes --copy The script supports:
• --repo-root <path>: repository containing skills-lock.json.
• --project: install into .agents/skills.
• --global: install into ~/.agents/skills.
• --if-needed: skip when the stamp matches the lock and locked skills are present.
• --prompt-for-target: prompt for project/global when no explicit target is set.
• --non-interactive: do not prompt; fail when no target is explicit.
• --force: install even if already up to date.
• --quiet: suppress no-op output.
• --verify-only: verify installed skills match skills-lock.json without installing. Successful install and skip paths verify that exactly one install target contains the locked common skills and that each installed skill matches skills-lock.json. Project installs add local Git exclude entries for only the locked common-skill directories so unrelated project skills in .agents/skills remain visible to Git. Global installs are shared across client repositories. A second repo pinned to the same lock verifies and succeeds without unnecessarily reinstalling; a repo pinned to a different lock fails with a version-mismatch error instead of overwriting the shared global install.

Update lock script

update_common_skills_lock non-interactively regenerates an existing skills-lock.json from the default branch of warpdotdev/common-skills without installing skills into the target repository. It generates a candidate in a temporary Git repository, then copies back only a changed skills-lock.json. Generator failures and missing candidate output fail the command instead of retaining the existing lock. Run it from a consuming repository:

/path/to/common-skills/scripts/update_common_skills_lock --repo-root /path/to/consumer

The downstream lockfile update workflow uses this command before opening lockfile-only pull requests.

Downstream lockfile workflow

.github/workflows/update-downstream-skill-locks.yml runs after every push to main and opens lockfile-only pull requests against warpdotdev/warp and warpdotdev/warp-server when their locks change. Each pull request requests the author of the originating common-skills pull request when possible and enables squash auto-merge. Direct pushes and authors who cannot review a target repository do not prevent pull request creation. The workflow requires a dedicated GitHub App installed on both downstream repositories with contents and pull-request write access. Configure its App ID as the COMMON_SKILLS_SYNC_APP_ID Actions variable and its private key as the COMMON_SKILLS_SYNC_APP_PRIVATE_KEY Actions secret in common-skills.

Remove script

remove_common_skills removes common agent skills listed in skills-lock.json. The script supports:

• --repo-root <path>: repository containing skills-lock.json.
• --project: remove from .agents/skills.
• --global: remove from ~/.agents/skills.
• --clear-lock: remove skills-lock.json after removing locked skills. The remove script only deletes paths derived from the lock file and includes path checks before removing project skill directories.

Verification

install_common_skills --verify-only checks that exactly one install target contains the locked common skills and that each installed skill matches skills-lock.json. Verification also runs after successful install and skip paths. Verification fails if:

• skills-lock.json is missing.
• Locked skills are installed in both project and global targets.
• Locked skills are missing from both targets.
• Any installed skill directory hash differs from the lock file.

Environment variables

• WARP_SKIP_COMMON_SKILLS_INSTALL=1: skip installation.
• WARP_COMMON_SKILLS_INSTALL_TARGET=project|global: explicit install or removal target.
• WARP_COMMON_SKILLS_TARGET_REPO_ROOT=/path/to/repo: repository containing skills-lock.json and project-local .agents/skills.
• WARP_COMMON_SKILLS_REF=<git-ref>: use a specific warpdotdev/common-skills branch, tag, or commit when creating a missing lock or checking interactively for lock updates.

Lock hash stamps

After a successful install, install_common_skills writes a stamp with the current skills-lock.json hash.

• Project installs use git path warp/common-skills-lock.hash, or .agents/skills/.common-skills-lock.hash when git metadata is unavailable.
• Global installs use ~/.agents/warp/common-skills-lock.hash. The stamp lets --if-needed avoid reinstalling when the lock file and installed skills are already current.
