# Skill activation check A skill only earns its keep if the model reaches for it at the right moment. That decision is made almost entirely from the skill's frontmatter `description` — so "does my skill trigger?" is a measurable question, and this is how you measure it: build a labelled set of user requests, run a real agent against each one, and score whether the skill was engaged. The user's request is: `$ARGUMENTS` ## Step 1 — Locate the target skill `$ARGUMENTS` may be a path to a `SKILL.md`, a path to the skill's **directory**, a skill name, or empty. - Empty: glob `.claude/skills/*/SKILL.md` and `**/skills/*/SKILL.md`. One match → use it. Several → list them and ask which. None → say so and stop. - A directory: use the `SKILL.md` inside it. - A name: find the matching skill directory. The **bare skill name is the directory name** containing `SKILL.md`. Read the frontmatter `description` and keep it in front of you: that string is what the model matches against, so it is the primary input to row design and the thing you will end up recommending edits to. **Measure its length while you are there — two separate budgets truncate it, and either one produces a low-recall result that looks exactly like bad wording.** 1. **Per-skill truncation.** `description` and `when_to_use` are concatenated and cut at a fixed character budget — **1,536 characters**, configurable via the `skillListingMaxDescChars` setting. Trigger text past the cutoff cannot affect

Forward Implementation First
181Vuk97/forward-implementation-first
Keeps an agent building and validating real output instead of servicing its own bookkeeping. Use for multi-stage pipelines, capability roadmaps, long-running implementation loops, migrations, staged data or build runs, and any run where administrative hashes, locks, receipts, dashboards, certification markers, or progress metadata can block correct work. Use when an agent refuses to advance, rewinds finished stages, or reruns unchanged work because a marker is missing or stale.
