Lifecycle events (where skills can be applied) The template defines these key events: - `PromptSubmit` (blocking, AI-visible) - `PreAbilityCreate` (blocking, AI-visible) - `PreAbilityCall` (blocking, AI-visible) - `PostAbilityCall` (non-blocking, infra-only) - `SessionStop` (non-blocking, infra-only) See `/.system/skills/ssot/repo/architecture-core-mechanisms/runtime-model/SKILL.md` for details. --- ## 2. Suggested usage patterns ### PromptSubmit (suggest) Goal: suggest relevant skills based on prompt keywords/intent patterns. Inputs: - user prompt text - (optional) current working scope inferred from routing Output: - a short list of recommended skill entrypoints under `/.system/skills/ssot/**` ### PreAbilityCreate / PreAbilityCall (guard) Goal: enforce guardrails when executing risky abilities. Inputs: - ability id / operation key - target files/paths (if known) Output: - allow/deny/requires_human (policy decision), plus recommended skills to consult --- ## 3. Safety notes - Avoid over-blocking: prefer `suggest` unless the risk is truly stop-the-line. - Any enforcement change that can block execution should require explicit human approval. --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/willyu1007) — claim your Tome and manage your conversions.
