+### Discover loops from your work
+
+Discovery looks for recurring engineering work in the sources you put in
+scope. In a codebase, that can include scripts, CI and deployment configuration,
+tests, runbooks, maintenance commands, and repeated lifecycle patterns. In
+coding threads, it groups equivalent completed work even when the wording
+differs.
+
+The skill requires at least two distinct thread occurrences before calling work
+repeated. A code pattern without run history is labeled as a potential loop, not
+proven recurrence. It then checks whether fresh feedback can change the next
+action, whether success can be verified, and whether the work has clear limits,
+stopping behavior, and approval boundaries. It also checks the live catalog to
+avoid recreating an existing loop.
+
+The skill can inspect only repositories and coding threads that your agent can
+access and that you place in scope. If thread history is unavailable, it uses
+the codebase evidence and says so. A discovery result includes compact source
+evidence and either a new loop, an adaptation of a published loop, a short
+candidate slate when your choice matters, or a clean no-op when nothing truly
+fits.
+
 When the skill finds or creates the right loop, it gives you a prompt to use
 with your agent. Review any placeholders, then ask the agent to run that prompt
 in the project you want it to work on. Selecting a loop does not start a

+# Loop Discovery
+
+Use this workflow when the user asks to mine a codebase, coding-thread history,
+or both for work that should become a loop.
+
+## Inspect the evidence
+
+1. Confirm the smallest discoverable scope from the request. Inspect the current
+   repository when it is clearly in scope. Use available thread listing, search,
+   and reading tools only for coding threads the user authorized. If thread
+   history is unavailable, continue with codebase evidence and disclose the
+   limitation.
+2. In code, inspect the operational paths that reveal recurring work: scripts,
+   CI and deployment configuration, maintenance commands, tests, contributor
+   instructions, issue templates, runbooks, and repeated lifecycle patterns.
+   Similar-looking functions alone are a refactoring signal, not proof of a
+   loop.
+3. In threads, identify completed actions and their outcomes. Group semantically
+   equivalent work even when the wording differs. Count distinct occurrences,
+   not repeated discussion of the same occurrence. Record a compact source
+   handle such as a thread title or identifier and the action performed; do not
+   copy secrets or unnecessary private content.
+4. Corroborate thread claims against the repository or runtime when practical.
+   Thread history can be stale, incomplete, or mistaken.
+
+## Qualify and rank candidates
+
+A repeated task is not automatically a good loop. Require the candidate to
+follow the feedback-cycle and validation rules in `SKILL.md`, not merely to
+appear multiple times in code or thread history.
+
+A candidate is loop-shaped only when all of these are present or can be derived
+from scoped evidence:
+
+- a recurring event or state to observe;
+- a next action that can change in response to fresh feedback;
+- an observable check for whether the action helped;
+- a bounded scope and a success, no-op, blocked, approval-required, or
+  no-progress stop as appropriate.
+
+Require at least two distinct occurrences before describing a thread-derived
+task as repeated. A codebase pattern without run history may be reported as a
+potential loop, but not as proven recurrent. Reject one-shot migrations,
+straight-line checklists, vague goals, and tasks where another pass receives no
+new evidence.
+
+Rank qualified candidates by evidence of recurrence, time or failure cost,
+quality of available feedback, reversibility, and safe authority. Do not invent
+frequency, effort saved, owners, schedules, metrics, or permissions. Prefer the
+smallest high-value loop over a broad loop that bundles unrelated work.
+
+## Convert the best candidate
+
+1. Search the live catalog using the candidate's outcome, trigger, action, and
+   verification terms. Adapt a strong published match instead of duplicating
+   it. If the catalog is unavailable, continue with an explicitly unpublished
+   design and disclose that duplication could not be checked.
+2. If several candidates are similarly strong or differ materially in
+   authority, show a short ranked slate and ask the user which one to convert.
+   Otherwise convert the strongest candidate directly.
+3. Derive the trigger, fresh observation, bounded action, reproducible
+   verification, record, and terminal behavior from the evidence. Apply every
+   design rule in `SKILL.md`; do not weaken the standard because recurrence is
+   well documented. Ask one short question only when a missing decision would
+   materially change safety or success.
+4. Run the mandatory crafted-loop preflight in `SKILL.md`. Repair material
+   weaknesses before delivery without expanding authority or inventing missing
+   details.
+5. Return the compact evidence and the loop using the standard delivery format
+   in `SKILL.md`. Label it as an unpublished design or adaptation. If no
+   candidate qualifies, report a clean no-op and explain the missing feedback
+   or recurrence evidence; do not manufacture a loop.
