interlinked-cowork

interlinked-cowork is a skill for Claude Code, Codex from QuentinCody/interlinked-cli. It costs 64 tokens per session (1,280 once invoked), scanned A, original, MIT.

A workflow for packaging, testing, and diagnosing an experimental plugin for Claude Desktop's Cowork mode. It covers plugin packages, lifecycle hooks, runtime paths, and checks of whether hooks work as expected.

In plain words
What is it for?
Use it to package and upload the plugin, inspect available capabilities, probe hook behaviour, and verify the installed version and runtime.
Why use it?
It helps distinguish desktop, cloud, device, and host problems when hooks fail or behave differently. A hook is code that runs at a particular stage of a tool's operation.

Skill for Claude CodeCodex

Written for Claude Code and Codex: PostToolUse hook event, but also agents/openai.yaml present. Also seen: mentions subagents; names the NotebookEdit tool; mentions Claude Code.

Good fit Use it to package and upload the plugin, inspect available capabilities, probe hook behaviour, and verify the installed version and runtime.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

interlinked-cowork scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Interlinked Cowork

Cowork uses an uploaded plugin, separately from Claude Code settings. Ordinary Desktop Chat supports plugin skills but does not expose Cowork's hooks. Do not run enable --clients cowork; use interlinked cowork package --output <fresh-directory> and upload the resulting .plugin in Desktop Customize → Plugins. Requires the built standalone runtime, Node in the hook environment, and zip on the packaging host. After replacement, verify the displayed version/hooks and start a fresh task.

Native evidence and limitations

Run interlinked cowork capabilities --json. Dated native evidence is distinct from the current installation, which remains unmeasured until probed. On Desktop 1.49585.0 cloud mode, native deny, ask, input rewrite, and post-tool context were observed. Hook crashes and provider timeouts allowed synthetic writes. The guard launcher converts child failures, missing Node, and a 12-second internal deadline to explicit denial before the 15-second native deadline. If the provider never launches or kills the entire hook, this wrapper cannot enforce anything.

The ordinary plugin installs six lifecycle/tool hooks. A separate --probe package registers the larger Claude Code event catalog, including failure/subagent events, to measure availability; registration does not establish emission or enforcement. Keep fault injection confined to synthetic tasks, then disable the probe plugin. Do not retry denied actions through another tool.

Normal PostToolUse hooks match only Write, Edit, MultiEdit, NotebookEdit, Bash and the exact device Bash tool; reads/searches and unrelated connector tools do not trigger them. Probe subscriptions remain broad. Host guidance is encoded in PreToolUse additionalContext, including ordinary allows without a permission override; post-write artifact feedback is appended to host findings. Receipts still exclude guidance text. Pre-tool context delivery on the current native installation needs its own probe; local encoder tests are not native enforcement evidence.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
