## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - An agent's runtime mounts only its own enabled skills; nothing tells
the model what else the company skill library holds
> - From inside a sandbox, "installed but not enabled for me" and "does
not exist" look identical, so agents tell users freshly installed skills
are not installed
> - This pull request renders the library as a deterministic markdown
section appended to claude-local agent instructions, and adds a
paperclipListSkills MCP tool
> - The benefit is that agents report the true state ("installed, not
enabled for me — ask an operator to enable it") instead of a false
negative
## Linked Issues or Issue Description
**What existing behavior does this improve?**
How agents reason about the company skill library at runtime.
**Subsystem affected**
`packages/adapter-utils` (new pure builder),
`packages/adapters/claude-local` (instructions append),
`packages/mcp-server` (new tool).
**Current behavior**
The runtime hands adapters the full library list, but only the agent's
enabled skills are mounted, and no prompt content or MCP tool describes
the rest. Agents inspect their sandbox, find nothing, and report
installed skills as not installed.
**Proposed behavior**
A "Company skill library" markdown section lists every skill as
`enabled`, `installed, not enabled for you`, or `enabled but
unavailable: <cause>`, with instructions to report the not-enabled state
accurately and ask an operator to enable it. claude-local appends it to
the agent instructions text. A `paperclipListSkills` MCP tool exposes
the same list on demand.
**Breaking changes**
None. Other adapters are untouched (they can adopt the builder later);
the manifest is deterministic, so the claude-local prompt-bundle cache
only busts when the library actually changes.
## What Changed
- New `packages/adapter-utils/src/skill-library-manifest.ts` with
`buildSkillLibraryManifestMarkdown` (pure, key-sorted, deterministic;
renders the missing-cause detail from #12146).
- `packages/adapters/claude-local/src/server/execute.ts` appends the
manifest to `combinedInstructionsContents` (creating it when no
instructions file is configured).
- `packages/mcp-server/src/tools.ts` adds `paperclipListSkills` hitting
`GET /companies/:companyId/skills`.
## Verification
- `npx vitest run
packages/adapter-utils/src/skill-library-manifest.test.ts` (from repo
root) — 3 tests: byte-identical output for shuffled input, state
rendering incl. the unavailable cause, change detection.
- `cd packages/mcp-server && npx vitest run` — new tool routing test
passes (13 passed; 1 pre-existing failure on my machine reproduces
unchanged at the branch base).
- `cd packages/adapters/claude-local && npx vitest run` — 244 passed, 1
skipped.
- `pnpm run typecheck` clean in adapter-utils, mcp-server, claude-local.
## Risks
- Prompt growth is one line per installed skill plus a five-line header
— bounded and only present when the library is non-empty. Stacked on
#12146 so the manifest's "enabled but unavailable" state reflects real
materialization failures.
## Model Used
- Claude Fable 5 (`claude-fable-5`, Anthropic) with extended thinking
and tool use, via Claude Code.

@paperclipai/adapter-utils
Shared utilities for Paperclip adapters: process spawning, environment injection, sandbox/SSH transport, workspace sync, and the round-trip helpers that move code between the local execution-workspace cwd and wherever the agent actually runs.
For the adapter-author guide see
docs/adapters/creating-an-adapter.md
and the in-repo notes at packages/adapters/AUTHORING.md.
No-remote-git contract
The local execution-workspace cwd is the only persistence boundary across runs. No adapter may depend on a git remote for cross-run state.
Adapters that run the agent on a different host should use the SSH round-trip
helpers in src/ssh.ts:
prepareWorkspaceForSshExecution({ spec, localDir, remoteDir })— bundles the local cwd (tracked files, dirty edits, untracked additions, and the git history needed to reconstruct it) toremoteDirbefore the run starts. Runs with nogit remoteconfigured.restoreWorkspaceFromSshExecution({ spec, localDir, remoteDir, ... })— syncs the remote cwd back intolocalDirafter the run, including any new commits the agent created. Also runs with nogit remoteconfigured.
prepareRemoteManagedRuntime in
src/remote-managed-runtime.ts wraps both
calls for adapters that want a per-run remote workspace and an automatic
restoreWorkspace() finally hook.
The invariant is pinned by the no-remote-git contract case in
src/ssh-fixture.test.ts, which asserts that a
remote-only commit propagates to the local worktree through the
prepare → restore round-trip with no git remote configured at any point. Do
not regress that test.
