Conciseness

The body is command-dense and assumes competence — no tutorial prose explaining Kubernetes or Falco basics — with Falco-specific semantics ('spawned_process — a new process was exec'd') legitimately included. Minor over-explanation remains: Mode: alerts step 4 ('Deduplication: set slack.minimumpriority: warning...') restates the minimumpriority already configured in step 2's YAML, and the harden Recovery section's re-apply-the-label logic is muddled, fitting anchor 4 ('minor instances... that could be trimmed') better than anchor 5's every-token-earns-its-place.

Actionability

Nearly everything is concrete and executable: copy-paste helm/kubectl commands, a complete Falco rule in YAML, Falcosidekick config, a Kyverno ValidatingPolicy, and an ordered debug checklist with exact commands. The gap: 'helm install falco ... -f examples/runtime-security/falco-values.yaml' and 'helm upgrade --install ... -f examples/runtime-security/falcosidekick-values.yaml' reference values files that do not exist in the bundle, so the flagship commands are not copy-paste runnable as written — anchor 4 ('minor gaps') rather than anchor 5's fully-executable standard.

Workflow Clarity

Each mode is a clearly numbered sequence with explicit validation checkpoints — 'Verify DaemonSet is running on all nodes', 'Confirm Falco is receiving events' with expected log output, the ordered six-step debug checklist ('Is Falco running? Is the rule loaded? Is the condition correct?...'), and event-generator as a synthetic test. The destructive harden path includes a feedback loop (Recovery: remove the label, grace-period pod deletion to drain in-flight requests), matching anchor 5's explicit validation, error-recovery loops, and checklists; anchor 4 would require missing checkpoints, and the destructive-operation cap does not apply since validation and recovery are present.

Progressive Disclosure

In-file structure is good (wizard up front, one clearly headed section per mode, a single load-more pointer), but scored against the actual bundle: no references/, scripts/, or assets/ directories exist, so the body's pointers — 'load references/runtime-security.md' and both '-f examples/runtime-security/*.yaml' values files — are dangling references to files not in the bundle. That fits anchor 3 ('references present but not clearly/fully resolvable; content that should be separate is inline' — all five modes live inline in a ~230-line SKILL.md) rather than anchor 4's well-organized one-level-deep references.

Specificity

Names the domain ('in-container threats at the syscall level using Falco') and multiple concrete actions — 'installation on EKS/GKE with eBPF driver, custom rule authoring, alert routing via Falcosidekick, rule debugging, and bridging Falco runtime signals to Kyverno admission enforcement' — covering all five skill modes comprehensively. The parenthetical '(eBPF-based, CNCF, open-source, no license cost)' is mild padding but not enough to drop below the anchor-5 bar; anchor 4 would require actual coverage gaps, and there are none.

Completeness

Explicitly answers both: the 'what' ('Detect and respond to in-container threats... Covers Falco installation... custom rule authoring, alert routing...') and the 'when' ('Use when asked to...') with concrete trigger phrases. This matches the anchor-5 good-example pattern exactly; anchor 4 would require the 'when' clause to be less explicit, and it is not.

Trigger Term Quality

Five natural quoted triggers — 'detect privilege escalation in containers', 'set up runtime threat detection', 'write a Falco rule', 'route Falco alerts to Slack', 'debug why my Falco rule is not firing' — plus tool keywords (Falco, Falcosidekick, Kyverno, EKS/GKE, Slack). A few natural variations are missing (e.g. 'eBPF monitoring', 'syscall alerts', 'Kubernetes runtime security'), which fits anchor 4 ('good keyword coverage; a few natural terms missing') rather than anchor 5's comprehensive synonym coverage.

Distinctiveness Conflict Risk

Mostly distinct — three of the five triggers name Falco explicitly ('write a Falco rule', 'route Falco alerts to Slack', 'debug why my Falco rule is not firing'). However, 'set up runtime threat detection' and 'detect privilege escalation in containers' are tool-agnostic and could also match sibling runtime-security skills (the body itself acknowledges a Kubescape overlap), giving minor overlap risk with closely related skills — anchor 4 rather than anchor 5's 'minimal conflict risk'.
