Source documentation, not instructions for this website. Review permissions before running any commands.
This project uses capshelf to track shared coding-agent config (skills, project-local Pi extensions, Claude/Codex subagents, settings fragments, MCP configs) pulled from a data repo. When the user asks to add, remove, discover, edit, or update shared config, use the capshelf CLI. Do not hand-edit .capshelf/capshelf.json or .capshelf/capshelf.lock.json — they are tool-managed.
Run project commands from anywhere inside a capshelf project — the directory containing .capshelf/capshelf.json, or any subdirectory of it (capshelf walks upward to find the root, like git). init acts on the current directory, not a discovered parent.
Use init only for a new project or a fresh clone without
.capshelf/local.json; it refuses a project already initialized on this
machine. Use data bind, data upstream, and update for later lifecycle
changes.
Work the shelf in this order instead of pattern-matching on bare item names:
Run capshelf status at session start to see drift and available updates before changing anything. capshelf ls --here lists what is already installed (with descriptions and #tags when the data repo declares them).
Reach for capshelf search <task words> first — it matches names, tags, descriptions, and item content across the bound data repo plus bundled system items, ranked by relevance:
capshelf search "sql injection"
capshelf search security --json
Zero matches exit 0 — an empty answer is a valid answer, not an error. To browse instead, use capshelf ls --tag <tag> (repeatable, AND) or ls --kind <kind>. Descriptions and tags are the selection signal.
Results with a bundles/ prefix are bundles — curated item sets. Prefer them when setting up a project: capshelf show bundles/<name> to preview members and install state, then capshelf add bundles/<name> to expand. Expansion is traceless (members become ordinary independent items); the bundle field in add --json is the only echo and is what belongs in a commit message.
capshelf show <item> prints the full description, requires, conflicts-with, and whether each relation is already installed. Use it before committing to an add. For pi-extensions/*, read all extension source shown before adding: Pi executes it as arbitrary code with full user permissions after project trust.
capshelf add <item>. For mcp/* and subagents/*, read the targets: block
add prints and tell the user which runtimes the item covers — see Target
coverage. Repeating add for an installed item is a stable no-op; use the printed status --diff, update, and apply guidance instead of trying to make add reapply it. If the output lists missing required items, install them with the exact capshelf add <ref> commands it prints. If add refuses with exit 3 because of a conflicts-with declaration, that is a curated incompatibility — surface the decision to the user (remove the conflicting item, or fix a stale declaration in the data repo); never work around it. A bundle preflight refusal (exit 3) is the same kind of decision: nothing was installed and the per-member report says why — surface it, don't install members one by one to route around it.
capshelf status --strict — exit 0 means the project has converged on its locks.
When the user asks you to improve a shared (data) item:
capshelf get-path <item> for the absolute editable path (fragments return canonical data-repo source files; --output returns generated outputs for inspection only).capshelf status <item> — should report drifted_local (or source_dirty for fragments).capshelf promote <item> -m "why" — push to the data repo. Other projects see update available next time they check; nothing auto-changes.capshelf keep-local <item> --reason "why" — intentional project-specific divergence for a copy item (skill or Pi extension).capshelf revert <item> — discard the edit, restore from the recorded sourceCommit; first show capshelf status <item> --diff and get permission before using --yes in a non-interactive run.For Pi extensions, inspect the changed source before promoting and tell the user to run /reload or restart Pi after materialization. Never imply that capshelf reviewed, trusted, sandboxed, or dependency-installed the extension.
If promote fails with "changed in the data repo since this project last updated" (exit 3), a teammate's newer version is upstream. Show the user the upstream diff (capshelf status <item> --diff plus the scoped git log from the error message). For a skill in either scope or a project-scope Pi extension, offer capshelf promote <item> --merge -m "why" to three-way merge the locked base, installed edits, and current upstream. A merge conflict lists paths and writes nothing. Other choices are preserving the edit and running capshelf update <item> before redoing it, or an intentional overwrite. Do not retry with --stale-ok on your own; --merge and --stale-ok are mutually exclusive. update preflights local drift and asks before replacing installed content; non-interactive and JSON calls refuse unless --yes is passed. Review capshelf status <item> --diff and get the user's permission before using update --yes. For a local-scope item, preserve --local on recovery and merge commands. A merged or ordinary promote that reports already-upstream means the lock was re-pinned without a data-repo commit.
To change metadata (tags, description, requires/conflicts-with, or declared needs), edit the item's canonical data-repo sidecar (skills/<name>/.capshelf.yml, pi/extensions/<name>/.capshelf.yml, or the fragment path shown by capshelf show) and commit it in the data repo. Metadata is never hashed into item content. Tags, descriptions, and relations are live catalog data and need no project update; needs are lock-pinned, so consuming projects run capshelf update <item> to select a changed declaration without reinstalling unchanged content. Commit the sidecar before returning to project work: an uncommitted sidecar edit blocks capshelf update entirely (dirty data repo) and blocks add of that item.
For a skill's description, prefer SKILL.md frontmatter — it doubles as the catalog fallback. Know the trade-off when choosing where to edit: a frontmatter edit is content drift (shipped to Claude, hashed — consuming projects see update available), while a sidecar edit is drift-free. Add a sidecar description only when the catalog blurb should differ from the frontmatter's invocation-trigger phrasing, or when tuning copy must not ship a content change; sidecar wins when both exist. Fragment items (settings/mcp/codex-config) have no frontmatter — the sidecar is their only description source.
For system items (e.g. this capshelf skill), the edit loop doesn't apply — to change them, edit the CLI source under src/bundled/ and rebuild.
~/code/work-skills/) holds canonical versions of every shared item under skills/, pi/extensions/, subagents/, settings/, mcp/, and codex/config/. It must be a git repo. Resolution order: --data <path> flag > gitignored .capshelf/local.json > $CAPSHELF_HOME. There is no implicit default..capshelf/capshelf.lock.json (clone-local pins in gitignored .capshelf/local.lock.json). Data-repo updates do NOT propagate until this project runs capshelf update..agents/skills/<name>/ by default with .claude/skills/<name> symlinks (Claude-only projects install directly under .claude/skills/<name>/). Pi extensions live under .pi/extensions/<name>/. Claude custom commands are modeled as skills.subagents/<name>/claude.md installs to .claude/agents/<name>.md; subagents/<name>/codex.toml installs to .codex/agents/<name>.toml. Either target or both may exist under one lock; capshelf reports which as target coverage.<item>/.capshelf.yml in the data repo: description, tags, requires, conflicts-with, needs) feeds discovery and checks. It is never copied into projects. Needs are pinned separately from content so requirements freshness never changes content drift.system/): bundled into the CLI binary, installed by init, read-only from a project's perspective.data/): live in your data repo. Added via add, removed via rm, adopted via share, pushed back via promote.Mutating commands only touch files tracked in the lockfiles: add refuses to overwrite an existing untracked target, and rm deletes only locked data items. Copy-directory items can use committed project scope or clone-local scope; subagents are project-only. share skills/<name> defaults to local scope; Pi extensions default to project scope, so pass --to local when adopting one as clone-local intent.
Always check the current surface with capshelf --help and capshelf <verb> --help. Most item arguments accept a bare unique name (hello) or a kind-qualified ref (skills/hello).
| verb | purpose |
|---|---|
init | initialize a new project or onboard a fresh clone without .capshelf/local.json; never use it to reinstall or rebind an initialized machine |
data bind / data upstream / data path | inspect or change the explicit data-repo binding (old set-data/set-upstream/data-path still work as aliases) |
ls / show / search / status | inspect and discover (all support --json; ls and status include user-level runtime skills by default, --user narrows to them only) |
add / rm / apply / update / revert | converge the project on its locks |
lock migrate | one-time conversion of this project's locks to version 4; required before any lock-writing command works on an older project |
share / move / promote / keep-local | flow content and intent between project and data repo |
data sync [--json] | explicitly fetch the bound data repo's origin and fast-forward when safe; the only capshelf command that touches the network besides the init bootstrap clone and self-update. Run it when the user asks to pick up teammates' changes, then capshelf status to see update_available |
get-path | print the editable path for an item; use `--target claude |
self-update | update the Homebrew-installed binary (not project pins) |
marketplace ... | author, validate, sync, and package data-repo Claude/Cowork or Codex plugin catalogs; never installs runtime plugins |
Locks written before version 4 identified an item by a hash of the data repo working tree. Version 4 identifies it by the item's committed Git tree. One lock file carries one identity model, never both, so the conversion is an explicit command instead of a side effect of the next write.
On a project whose lock is version 2 or 3, every command that writes a lock
refuses with exit 3: add, rm, update, revert, promote, share,
move, keep-local, bundle installs, and init. The refusal reads:
✗ this project's lock is version 3; capshelf add writes lock version 4
Convert the project and local locks first: capshelf lock migrate (preview it with --dry-run).

Survey the project Run `capshelf status` at session start to see drift and available updates before changing anything. `capshelf ls --here` lists what is already installed (with descriptions and `#tags` when the data repo declares them). ### 2. Discover on the shelf Reach for `capshelf search <task words>` first — it matches names, tags, descriptions, and item content across the bound data repo plus bundled system items, ranked by relevance: ``` capshelf search "sql injection" capshelf search security --json ``` Zero matches exit 0 — an empty answer is a valid answer, not an error.

Evaluate before installing `capshelf show <item>` prints the full description, `requires`, `conflicts-with`, and whether each relation is already installed. Use it before committing to an `add`. For `pi-extensions/*`, read **all extension source** shown before adding: Pi executes it as arbitrary code with full user permissions after project trust. ### 4. Install `capshelf add <item>`. For `mcp/*` and `subagents/*`, read the `targets:` block add prints and tell the user which runtimes the item covers — see Target coverage. Repeating add for an installed item is a stable no-op; use the printed `status --diff`, `update`, and `apply` guidance instead of trying to make add reapply it.

Verify `capshelf status --strict` — exit 0 means the project has converged on its locks. ### 6. Edit / promote loop When the user asks you to improve a shared (data) item: 1. `capshelf get-path <item>` for the absolute editable path (fragments return canonical data-repo source files; `--output` returns generated outputs for inspection only). 2. Edit with your Edit/Write tools. 3. `capshelf status <item>` — should report `drifted_local` (or `source_dirty` for fragments). 4. Decide with the user: - `capshelf promote <item> -m "why"` — push to the data repo. Other projects see `update available` next time they check; nothing auto-changes. - `capshelf keep-local <item> --reason "why"` — intentional project-specific divergence for a copy item (skill or Pi extension). - `capshelf revert <item>` — discard the edit, restore from the recorded `sourceCommit`; first show `capshelf status <item> --diff` and get permission before using `--yes` in a non-interactive run. For Pi extensions, inspect the changed source before promoting and tell the user to run `/reload` or restart Pi after materialization. Never imply that capshelf reviewed, trusted, sandboxed, or dependency-installed the extension. If `promote` fails with "changed in the data repo since this project last updated" (exit 3), a teammate's newer version is upstream. Show the user the upstream diff (`capshelf status <item> --diff` plus the scoped `git log` from the error message). For a skill in either scope or a project-scope Pi extension, offer `capshelf promote <item> --merge -m "why"` to three-way merge the locked base, installed edits, and current upstream.

Other choices are preserving the edit and running `capshelf update <item>` before redoing it, or an intentional overwrite. **Do not retry with `--stale-ok` on your own**; `--merge` and `--stale-ok` are mutually exclusive. `update` preflights local drift and asks before replacing installed content; non-interactive and JSON calls refuse unless `--yes` is passed.

A merged or ordinary promote that reports `already-upstream` means the lock was re-pinned without a data-repo commit.

Tags, descriptions, and relations are live catalog data and need no project update; needs are lock-pinned, so consuming projects run `capshelf update <item>` to select a changed declaration without reinstalling unchanged content. **Commit the sidecar before returning to project work**: an uncommitted sidecar edit blocks `capshelf update` entirely (dirty data repo) and blocks `add` of that item. For a skill's **description**, prefer SKILL.md frontmatter — it doubles as the catalog fallback. Know the trade-off when choosing where to edit: a frontmatter edit is content drift (shipped to Claude, hashed — consuming projects see `update available`), while a sidecar edit is drift-free. Add a sidecar `description` only when the catalog blurb should differ from the frontmatter's invocation-trigger phrasing, or when tuning copy must not ship a content change; sidecar wins when both exist. Fragment items (settings/mcp/codex-config) have no frontmatter — the sidecar is their only description source. For system items (e.g. this `capshelf` skill), the edit loop doesn't apply — to change them, edit the CLI source under `src/bundled/` and rebuild. ## How it works - **Data repo** (e.g. `~/code/work-skills/`) holds canonical versions of every shared item under `skills/`, `pi/extensions/`, `subagents/`, `settings/`, `mcp/`, and `codex/config/`. It must be a git repo. Resolution order: `--data <path>` flag > gitignored `.capshelf/local.json` > `$CAPSHELF_HOME`. There is no implicit default. - **This project** pins the exact content hash + source commit of each item in `.capshelf/capshelf.lock.json` (clone-local pins in gitignored `.capshelf/local.lock.json`). Data-repo updates do NOT propagate until this project runs `capshelf update`. - **Installed copies** live under `.agents/skills/<name>/` by default with `.claude/skills/<name>` symlinks (Claude-only projects install directly under `.claude/skills/<name>/`). Pi extensions live under `.pi/extensions/<name>/`. Claude custom commands are modeled as skills. - **Subagents** are project-scoped logical items. `subagents/<name>/claude.md` installs to `.claude/agents/<name>.md`; `subagents/<name>/codex.toml` installs to `.codex/agents/<name>.toml`. Either target or both may exist under one lock; capshelf reports which as target coverage. - **Item metadata** (optional `<item>/.capshelf.yml` in the data repo: `description`, `tags`, `requires`, `conflicts-with`, `needs`) feeds discovery and checks. It is never copied into projects. Needs are pinned separately from content so requirements freshness never changes content drift. ## Two kinds of items - **system** (lock prefix `system/`): bundled into the CLI binary, installed by `init`, read-only from a project's perspective. - **data** (lock prefix `data/`): live in your data repo. Added via `add`, removed via `rm`, adopted via `share`, pushed back via `promote`. Mutating commands only touch files tracked in the lockfiles: `add` refuses to overwrite an existing untracked target, and `rm` deletes only locked data items. Copy-directory items can use committed project scope or clone-local scope; subagents are project-only. `share skills/<name>` defaults to local scope; Pi extensions default to project scope, so pass `--to local` when adopting one as clone-local intent. ## Command reference Always check the current surface with `capshelf --help` and `capshelf <verb> --help`. Most item arguments accept a bare unique name (`hello`) or a kind-qualified ref (`skills/hello`). | verb | purpose | |---|---| | `init` | initialize a new project or onboard a fresh clone without `.capshelf/local.json`; never use it to reinstall or rebind an initialized machine | | `data bind` / `data upstream` / `data path` | inspect or change the explicit data-repo binding (old `set-data`/`set-upstream`/`data-path` still work as aliases) | | `ls` / `show` / `search` / `status` | inspect and discover (all support `--json`; `ls` and `status` include user-level runtime skills by default, `--user` narrows to them only) | | `add` / `rm` / `apply` / `update` / `revert` | converge the project on its locks | | `lock migrate` | one-time conversion of this project's locks to version 4; required before any lock-writing command works on an older project | | `share` / `move` / `promote` / `keep-local` | flow content and intent between project and data repo | | `data sync [--json]` | explicitly fetch the bound data repo's origin and fast-forward when safe; the **only** capshelf command that touches the network besides the `init` bootstrap clone and `self-update`. Run it when the user asks to pick up teammates' changes, then `capshelf status` to see `update_available` | | `get-path` | print the editable path for an item; use `--target claude|codex` for multi-target subagents | | `self-update` | update the Homebrew-installed binary (not project pins) | | `marketplace ...` | author, validate, sync, and package data-repo Claude/Cowork or Codex plugin catalogs; never installs runtime plugins | ## Lock version 4 migration Locks written before version 4 identified an item by a hash of the data repo working tree. Version 4 identifies it by the item's committed Git tree. One lock file carries one identity model, never both, so the conversion is an explicit command instead of a side effect of the next write. On a project whose lock is version 2 or 3, **every command that writes a lock refuses with exit 3**: `add`, `rm`, `update`, `revert`, `promote`, `share`, `move`, `keep-local`, bundle installs, and `init`. The refusal reads: ```text ✗ this project's lock is version 3; capshelf add writes lock version 4 Convert the project and local locks first: capshelf lock migrate (preview it with --dry-run). ``` `status`, `ls`, `sh
