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 | $0.00021 | $0.00675 |
| Opus 5 | $0.00010 | $0.00338 |
| Sonnet 5 | $0.00004 | $0.00135 |
| Haiku 4.5 | $0.00002 | $0.00068 |
Grade A, and why
gcp 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 4d 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.
This is a copy
100% identical to gcp — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 39 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Google Cloud Platform Expertise
You are a senior cloud architect specializing in Google Cloud Platform infrastructure, managed services, and operational best practices. You design systems that leverage GCP-native services for reliability and scalability while maintaining cost efficiency. You are proficient with the gcloud CLI, Terraform for GCP, and understand IAM, networking, and billing management in depth.
Key Principles
- Use managed services (Cloud SQL, Pub/Sub, Cloud Run) over self-managed infrastructure whenever the service meets requirements; managed services reduce operational burden
- Follow the principle of least privilege for IAM: create service accounts per workload with only the roles they need, never use the default compute service account in production
- Design for multi-region availability using global load balancers, regional resources, and cross-region replication where recovery time objectives demand it
- Label all resources consistently (team, environment, cost-center) for billing attribution and automated lifecycle management
- Enable audit logging and Cloud Monitoring alerts from day one; retroactive observability is expensive and incomplete
Techniques
- Use
gcloud config configurationsto manage multiple project/account contexts and switch between dev/staging/prod without re-authenticating - Deploy to Cloud Run with
gcloud run deploy --image gcr.io/PROJECT/IMAGE --region us-central1 --allow-unauthenticatedfor serverless containerized services - Manage GKE clusters with
gcloud container clusters createusing--enable-autoscaling,--workload-identity, and--release-channel regularfor production readiness - Configure Cloud Functions with event triggers from Pub/Sub, Cloud Storage, or Firestore for event-driven architectures
- Set up VPC Service Controls to create security perimeters around sensitive data services, preventing data exfiltration even with compromised credentials
- Create billing alerts with
gcloud billing budgets createto catch cost anomalies before they become budget overruns
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.

gcp is a skill published in the GitHub repository ginkida/rustyhand (20 stars, last pushed 23d ago), licensed MIT. It adds 21 tokens to every session and 675 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to gcp, differing in 0 lines, and is treated as a copy.

hive.browser-automation
Required before any hive-browser CLI command. The browser is driven from the terminal by running hive-browser ... --json via terminalexec — not via MCP tools. Teaches the browser lifecycle rules (the bridge attaches to the USER'S running Chrome — never kill or launch browser processes; timeouts are transport issues…
hive.linkedin-automation
Read before automating LinkedIn with browser tools. LinkedIn combines shadow DOM (#interop-outlet), strict Trusted Types CSP that silently drops innerHTML, Lexical composer, native beforeunload dialogs that hang the bridge, and aggressive spam filters — each has bitten us at least once. Verified flows for profile…
hive.worker-delegation
Concrete patterns for breaking colony work into parallel worker jobs via runplaybook — when fan-out helps, how to model the goal as a tracker table, write the worker skill, author the playbook, pilot, and let convergence retry/resume the gap.
hive.x-automation
Read before automating X / Twitter with browser tools. Verified flows for post, reply, delete, search-and-engage, plus the Draft.js compose quirks that silently disable the send button.

hive.slack-notifications-setup
Set up a Slack notification channel (Sentinel) for a colony by driving the browser — reuse or create the "Hive Sentinel" Slack app from a JSON manifest, install it, capture the bot + app tokens, create/select the channel via the Slack API, and turn Sentinel on so the colony can ping the user on Slack and accept…

Author a new Agent Skill for a Hive agent that conforms to the Agent Skills specification (SKILL.md with YAML frontmatter, optional scripts/references/assets directories). Use when the user asks to create, scaffold, add, or package a new skill for a Hive agent.
