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 medium
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 →

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 | $0.00048 | $0.02795 |
| Opus 5 | $0.00024 | $0.01398 |
| Sonnet 5 | $0.00010 | $0.00559 |
| Haiku 4.5 | $0.00005 | $0.00280 |
Grade A, and why
enable-ssi 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 9d 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.

Enable APM on Kubernetes via Single Step Instrumentation
Before doing anything else: Fully resolve all variables in
## Context to resolve before acting. Do not begin Step 0 until every variable has a concrete value.
Silent failure — check this before any other step:
If the application has
ddtrace,dd-trace, or any OpenTelemetry SDK in its dependency manifest (requirements.txt,package.json,Gemfile,go.mod,pom.xml) — even with no import statements in code — SSI will silently disable itself at runtime.The failure is invisible: init containers run and complete, the pod starts healthy, no errors appear in
kubectlorpup, but no traces arrive. The injector detects the user-installed tracer and exits cleanly without logging anything.Claude runs
grep -rE "ddtrace|dd-trace|opentelemetry" \ requirements.txt package.json Gemfile go.mod pom.xml 2>/dev/null \ || echo "No tracer dependency found"If any match — stop. Remove the package entirely (not just the import), rebuild the image, reload it into the cluster, and restart the pod before continuing. A package present in the manifest is enough to trigger this even if it is never imported.
Triggers
Invoke this skill when the user expresses intent to:
- Enable APM on a Kubernetes cluster
- Instrument Kubernetes applications with Datadog tracing
- Set up Single Step Instrumentation (SSI)
Do NOT invoke this skill if:
- The Datadog Agent is not yet installed — run
agent-installfirst - The user wants to verify SSI after setup — use
verify-ssi - The user wants to enable Profiler, AppSec, or Data Streams — use
dd-apm-k8s-sdk-features
Prerequisites
These are not a reading exercise — actively verify each one before proceeding.
Environment
- Datadog Agent is installed and healthy —
agent-installcomplete - Kubernetes v1.20+
- Linux node pools only — Windows pods require explicit namespace exclusion
- Cluster is not ECS Fargate — unsupported
- Not a hardened SELinux environment — unsupported
- Not a very small VM instance (e.g. t2.micro) — SSI can hit init timeouts
- No PodSecurity baseline or restricted policy enforced
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.

enable-ssi is a skill published in the GitHub repository datadog-labs/agent-skills (166 stars, last pushed 13d ago), licensed MIT. It adds 48 tokens to every session and 2,795 once invoked, about $0.0002 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 2026-08-30.
