Skill: haipipe-end-trig

Per-Fn-type specialist for TrigFn — the inference function that decides whether (and when) to run prediction based on incoming data. One of the 5 inference Fn-types inside an Endpoint_Set. See ref/concepts.md for TrigFn semantics.

Verb axis: design | review | list | concepts Use case: each TrigFn impl is scoped to ONE input cadence (e.g., CGM 5-minute stream, weight day entry, generic any-invocation). design and review take a use_case argument.

Commands

/haipipe-end-trig                                       -> show TrigFn ref (concepts mode)
/haipipe-end-trig concepts                              -> same
/haipipe-end-trig list                                  -> list known use-case impls in fn_trig/
/haipipe-end-trig design <use_case> [endpoint_set]      -> scaffold a new TrigFn for <use_case>
/haipipe-end-trig review <use_case> [endpoint_set]      -> structural audit of one use-case impl

Use cases (concrete impls in code/haifn/fn_endpoint/fn_trig/, as of 2026-04-25 — discover current impls with ls code/haifn/fn_endpoint/)

AnyInv_v250205         generic any-invocation trigger (always fires)
CGM5Min_v260101        CGM 5-minute stream trigger
WeightDayEntry_v260305 weight day-entry trigger

If <use_case> is omitted, the skill should Bash("ls code/haifn/fn_endpoint/fn_trig/") and ask the user to pick.

Step-by-Step Protocol

Step 0: Read ref/concepts.md — TrigFn semantics, condition evaluation, gate logic. Step 1: For design, also read ../haipipe-end/fn/fn-design.md + ../haipipe-end/ref/0-overview.md. For review, also read ../haipipe-end-endpointset/fn/fn-review.md. Step 2: Execute the procedure scoped to TrigFn. Step 3: Emit the structured tail.

Scope

Owns:

• TrigFn concept ref (ref/concepts.md)
• TrigFn design + review scoped to ONE Fn-type

Does NOT own:

• Other 4 Fn-types — sibling skills -meta, -post, -src2input, -input2src
• Whole-artifact verbs — /haipipe-end-endpointset
• Deployment — /haipipe-end-deploy-*
