The red → green → refactor loop is anchored by leading words the model
already holds, so the step-by-step Workflow mostly restated the loop and
duplicated the horizontal-slicing anti-pattern. Drop the Workflow and
per-cycle checklist; fold their durable idea (vertical slices / tracer
bullets) into Anti-patterns and a short Rules-of-the-loop list.
Introduce **seam** as the leading word for where tests go, collapsing the
old Philosophy "public interfaces" prose and the Planning "confirm
interface / behaviors" handshake into one rule: test only at pre-agreed
seams, confirmed with the user before any test is written.

Tests whose assertion is recomputed the way the code computes it pass by
construction and give zero confidence. Add it as a peer of the existing
implementation-coupling anti-pattern: a Philosophy principle, a per-cycle
checklist gate, and a BAD/GOOD example pair in tests.md. Includes a patch
changeset.

Replace numeric ticket ids (#1, #2…) with short, token-efficient
dash-case slugs (e.g. relational-db) that read as mini-titles. Update
the Structure example, the next-ticket selection rule (lowest-numbered →
first in document order), the optional-arg wording, and the Handoff
copy-paste examples accordingly.

Add `publish: npx changeset tag` to the release workflow and enable
tagging for private packages in the changesets config, so merging a
Version PR creates a git tag and GitHub release.

Add changesets for tracking and versioning skill changes:
- package.json (private) + @changesets/cli and @changesets/changelog-github
- .changeset/config.json using the GitHub release-style changelog
- release workflow that opens a version PR on push to main (no npm publish)
- initial changeset recording recent skill updates

Add a Pruning directive to run the no-op test sentence by sentence and
delete whole failing sentences rather than trim words. References the
existing no-op test as single source of truth — no restated definition.

- Validate the fixed point resolves and diff is non-empty before spawning sub-agents
- Single-source the tooling-enforced and two-axis rationale (point to Why two axes)
- Fix rerank contradiction: summarize worst issue per axis, not across axes
- Drop dead "Read X, then read the diff" preambles from both briefs

Adds a new engineering skill that turns loose ideas with many
interdependent open decisions into a sequenced DAG of one-session
investigation tickets, driving them to resolution one at a time.
Sits at the front of the pipeline, before /to-prd.
