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.

SkillSpector: 4 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Privilege Escalation · line 466 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

- medium Rogue Agent · line 43 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
- medium Prompt Injection · line 301 Subtle instructions detected that may alter agent decision-making or introduce hidden biases.Fix: Review content for implicit steering or bias. Ensure instructions are explicit and align with the skill's stated purpose.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00086 | $0.05803 |
| Opus 5.5 | $0.00034 | $0.02321 |
| Sonnet 5.5 | $0.00017 | $0.01161 |
| Haiku 4.5 | $0.00009 | $0.00580 |
Grade B, and why
dev-cluster scanned grade B with 2 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.
Subtle steeringmediumPrompt injection
Instructions that bias recommendations or shape behaviour without the user noticing.
**CRITICAL:** Never tell the user "the cluster is ready" or provide a URL without first confirming the frontend responds. A URL that doesn't load is worse than no URL. Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

Development Cluster Management Skill
Multi-cluster support: Each worktree/branch automatically gets its own isolated Kind cluster via
CLUSTER_SLUG. The Makefile derivesKIND_CLUSTER_NAME,KIND_HTTP_PORT,KIND_HTTPS_PORT,KIND_FWD_FRONTEND_PORT, andKIND_FWD_BACKEND_PORTfrom the slug. Runmake kind-statusto see the current assignments. Never hardcode cluster names or ports — always use the Makefile variables (in make targets) or their exported env-var equivalents (in shell commands).
You are an expert Ambient Code Platform (ACP) DevOps Specialist. Your mission is to help developers efficiently manage local development clusters for testing platform changes.
Your Role
Help developers test their code changes in local Kubernetes clusters (kind) by:
- Understanding what components have changed
- Determining which images need to be rebuilt
- Managing cluster lifecycle (create, update, teardown)
- Verifying deployments and troubleshooting issues
Platform Architecture Understanding
The Ambient Code Platform consists of these containerized components:
| Component | Location | Image Name | Purpose |
|---|---|---|---|
| Backend | components/backend |
vteam_backend:latest |
Go API for K8s CRD management |
| Frontend | components/frontend |
vteam_frontend:latest |
NextJS web interface |
| Operator | components/operator |
vteam_operator:latest |
Kubernetes operator (Go) |
| Runner | components/runners/ambient-runner |
vteam_claude_runner:latest |
Python Claude Code runner |
| State Sync | components/runners/state-sync |
vteam_state_sync:latest |
S3 persistence service |
| Public API | components/public-api |
vteam_public_api:latest |

What ships with it
2 files 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.
- 1mo ago First seen · 644 lines · 86 tokens per session scan B ac54b09f67a8
dev-cluster is a skill published in the GitHub repository ambient-code/platform (131 stars, last pushed yesterday), licensed MIT. It adds 86 tokens to every session and 5,803 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it B with 2 findings (subtle steering, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
