Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00053 | $0.00446 |
| Opus 5 | $0.00026 | $0.00223 |
| Sonnet 5 | $0.00011 | $0.00089 |
| Haiku 4.5 | $0.00005 | $0.00045 |
Grade A, and why
connected-services-bridge 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 11d 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 — 36 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Connected Services Bridge
Use this skill to discover available connected-service capabilities and perform scoped, user-authorized actions across approved services.
Workflow
- Identify the requested service, data scope, intended action, and expected output. Ask a focused question if any of these are ambiguous.
- Discover the relevant connector and inspect its documented operation and parameter schema. Do not assume tool names, permissions, or data locations.
- Use the least-privileged operation that can satisfy the request. Prefer a read-only check before any write.
- For a consequential action, present the target service, destination, affected files or records, and rollback option. Obtain explicit approval before creating, updating, sending, deleting, committing, or sharing anything.
- Perform the approved action. Verify the returned identifier, link, or status without exposing credentials, tokens, or private content.
- Report the result, the exact scope completed, and any local fallback artifact if the service was unavailable.
Reliability
Retry only transient, idempotent operations and stop after a small bounded number of attempts. For unavailable connectors, permission errors, or ambiguous results, preserve the local work and explain the blocker rather than guessing or escalating privileges.
Safety & Ethics
Required approvals
Require explicit user approval before remote writes, outbound communication, repository pushes, calendar changes, retention changes, or deletion. Treat a request to prepare an artifact as distinct from authorization to upload or publish it.
Prohibited actions
- Do not collect, reveal, store, or transmit credentials, tokens, or private data unnecessarily.
- Do not enable background synchronization, recurring jobs, or automatic cross-service actions without the user's specific approval.
- Do not bypass service permissions, authentication, access controls, CAPTCHAs, or platform safeguards.
- Do not silently create, update, share, delete, commit, or push remote content.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
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.

connected-services-bridge is a skill published in the GitHub repository Stijnman/grok-custom-skills (9 stars, last pushed today), licensed MIT. It adds 53 tokens to every session and 446 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
