Goal Capsule

Objective
Remove the unmaintained ce-work-beta skill (the Codex shell-out delegation experiment) and complete every cleanup the repo's conventions require, while preserving the reusable external-delegation learnings.
Authority
Trevin Chow (plugin maintainer). The Product Contract is the source of truth; planning corrections to it are noted below.
Execution profile
Single small PR off a feature branch. Mechanical removal plus one documentation edit; no architectural risk.
Stop conditions
Stop and surface if removing the skill breaks a test whose intent is to verify live delegation behavior in a way the plan didn't anticipate, or if release:validate fails for a reason other than the skill count. Do not expand scope into the historical plan docs or CHANGELOG.
Tail ownership
Implementer runs bun test and bun run release:validate to green, then opens a PR with a chore(ce-work-beta):-scoped title. All changes to main go through the PR; no direct push.
Open blockers
None.

Product Contract

Product Contract preservation Requirements unchanged in intent. R5 clarified: there is no skill count stored in a release manifest — the count lives in README prose (R4) and one test assertion (tests/release-metadata.test.ts), and release:validate auto-derives counts from disk. R5 is reframed from "sync the release manifest count" to "fix the README + test count and run release:validate to confirm sync." No product-scope change.

Summary

Delete the ce-work-beta skill from the plugin and perform the full set of cleanups its removal triggers: stale-install registries, the README inventory and skill count, the delegation-parity contract tests, and the release-metadata test count. The skill is beta and disable-model-invocation: true with no downstream handoffs, so removal is a hard delete rather than a deprecation. The Codex token-economics learnings are kept as a standalone reference; the now-moot promotion checklist is deleted.

Problem Frame

ce-work-beta was a beta surface for routing implementation work to the Codex CLI via codex exec. The delegation machinery — config parsing, per-batch effort selection, sandbox routing, and the ~23 KB delegation-workflow reference — has ongoing carrying cost. Keeping the shell-out path correct as ce-work evolves means maintaining a parallel orchestration surface that stayed beta, manual-only, and isolated from planning/workflow handoffs by design. The maintenance burden now outweighs the value the experiment returns, so the experiment ends.

Requirements

Skill removal
IDRequirement
R1Delete the entire skills/ce-work-beta/ directory tree, including SKILL.md and all files under references/.
Stale-install cleanup
IDRequirement
R2Add ce-work-beta (dash variant) to STALE_SKILL_DIRS in src/utils/legacy-cleanup.ts so upgrades sweep the flat-install skill directory. The colon variant ce:work-beta is already present and stays.
R3Add ce-work-beta to EXTRA_LEGACY_ARTIFACTS_BY_PLUGIN["compound-engineering"].skills in src/data/plugin-legacy-artifacts.ts for the same reason.
Inventory and release sync
IDRequirement
R4Update README.md: remove the /ce-work-beta inventory row and change the stated skill count from 27 to 26.
R5Fix the hardcoded skill-count assertion in tests/release-metadata.test.ts (27 to 26) and run bun run release:validate to confirm metadata is in sync. The count auto-derives from skill directories; do not hand-bump release-owned versions.
Knowledge preservation
IDRequirement
R6Edit docs/solutions/best-practices/codex-delegation-best-practices.md to read as a standalone external-delegation reference: keep the token-economics and batching learnings, remove the parts that depend on ce-work-beta existing as a live skill.
R7Delete docs/solutions/skill-design/ce-work-beta-promotion-checklist.md — no longer applicable once the skill is removed rather than promoted.
Tests
IDRequirement
R8Remove the ce-work-beta delegation-parity assertions in tests/pipeline-review-contract.test.ts (the tests that read the deleted skill to verify it mirrors ce-work).
R9Repair the remaining test references so bun test passes: fix the stale-install cleanup tests to stop reading the deleted SKILL.md while keeping their sweep assertions, drop ce-work-beta from the user-invoked-skills set, and repoint the converter example off the dead name.

Scope Boundaries

Not in scope
  • The historical plan docs in docs/plans/ that mention ce-work-beta as an active work surface stay untouched — they record past state, and version control holds history.
  • Existing CHANGELOG.md entries referencing ce-work-beta are left as-is — release-owned history, not hand-edited here.
Explicitly rejected Promoting Codex delegation into stable ce-work. The decision is to end the experiment, not graduate it; the promotion path is being deleted, not taken.

Planning Contract

Key Technical Decisions

KTD1Hard delete, not a deprecation stub The skill is beta, disable-model-invocation: true, and no other skill (planning, brainstorm, lfg, compound) hands off to it, so there is no user path to soften. The directory is removed outright and the name is added to the cleanup registries so existing flat installs get swept on upgrade.
KTD2Add the dash variant only to the two registries that lack it legacy-cleanup.ts already carries ce-work-beta in STALE_PROMPT_FILES, LEGACY_SKILL_DESCRIPTION_ALIASES, LEGACY_PROMPT_CURRENT_SKILL_FOR_FILE, and LEGACY_PROMPT_DESCRIPTION_ALIASES from the earlier ce:ce- rename. Only STALE_SKILL_DIRS (R2) and the artifacts skills array (R3) are missing the dash variant. Add only those two; do not duplicate the existing entries.
KTD3Keep the stale-install cleanup tests; delete only the delegation-parity tests The registries continue to target ce-work-beta, so "a leftover ce-work-beta install gets swept" stays a tested behavior. The legacy-cleanup tests keep that assertion but must stop reading the deleted skills/ce-work-beta/SKILL.md (replace the runtime pluginDescription(...) read with the literal historical description already encoded in LEGACY_SKILL_DESCRIPTION_ALIASES). The pipeline-review-contract tests verify a capability that no longer exists and are deleted whole.
KTD4The skill count is README prose plus one test assertion, not a release manifest value getCompoundEngineeringCounts in src/release/metadata.ts derives the count from on-disk skill directories. release:validate reports it but does not fail on a README mismatch and does not write the count back. The only enforced copy is tests/release-metadata.test.ts:150 (caught by bun test). So the count fix is two hand-edits (README prose + that assertion), not a manifest bump.

Assumptions

Sources & Research


Implementation Units

U1. Delete the ce-work-beta skill tree

Goal
Remove the skill itself.
Requirements
R1
Dependencies
None
Files
skills/ce-work-beta/ (entire tree: SKILL.md + references/)
Execution noteLand U1 together with U3 in the same PR — deleting the tree red-lines the tests that read it until U3 lands. The PR tip must be green.
Approach & verification

Pure deletion of the directory. After this, countSkillDirectories returns 26 automatically. No code references the skill at import time — all remaining references are string literals in tests and registries handled by other units.

Test expectation: none — pure file deletion; the absence is proven by U3's suite repair and the Verification Contract grep.

Verification: skills/ce-work-beta/ no longer exists.

U2. Add dash variant to the two cleanup registries

Goal
Ensure existing installs sweep the now-stale ce-work-beta skill directory on upgrade.
Requirements
R2, R3
Dependencies
None
Files
src/utils/legacy-cleanup.ts, src/data/plugin-legacy-artifacts.ts
Approach, patterns & test scenarios

Approach: Add the string "ce-work-beta" to STALE_SKILL_DIRS (next to the existing "ce:work-beta") and to EXTRA_LEGACY_ARTIFACTS_BY_PLUGIN["compound-engineering"].skills (next to its "ce:work-beta"). Per KTD2, do not touch the prompt-file / description-alias registries — they already carry the dash variant.

Patterns to follow: mirror the adjacent ce:work-beta entries; keep alphabetical/grouped ordering consistent with neighbors.

Test scenarios:

  • Cleanup sweep: a fixture containing a stale ce-work-beta skill directory is removed by the cleanup routine (extends the existing prompt-file sweep coverage to the skill-dir registry entry).
  • Registry membership: STALE_SKILL_DIRS and the artifacts skills array each contain both ce:work-beta and ce-work-beta.

Verification: the cleanup tests in U3 pass with the new entries.

U3. Repair the test suite

Goal
Make bun test green after the skill and its parity surface are gone.
Requirements
R5, R8, R9
Dependencies
U1, U2
Files
tests/pipeline-review-contract.test.ts, tests/legacy-cleanup.test.ts, tests/skill-conventions.test.ts, tests/copilot-converter.test.ts, tests/release-metadata.test.ts
Approach & test scenarios

Approach (per file):

  • pipeline-review-contract.test.ts — delete the four named ce-work-beta tests and the ce:work-beta codex delegation contract describe block (all read the deleted skill to assert delegation parity). (R8)
  • legacy-cleanup.test.ts — keep both tests that assert a stale ce-work-beta.md wrapper is removed, but replace the pluginDescription("skills/ce-work-beta/SKILL.md") runtime read with the literal historical description string (already encoded in LEGACY_SKILL_DESCRIPTION_ALIASES), so the test no longer depends on the deleted file. (R9, KTD3)
  • skill-conventions.test.ts — remove "ce-work-beta" from EXPECTED_USER_INVOKED_SKILLS. (R9)
  • copilot-converter.test.ts — repoint the multi-colon transform example off the dead skill name (use a live or neutral example) so no test references a removed skill. (R9)
  • release-metadata.test.ts — change the skills: 27 assertion to 26. (R5)

Test scenarios:

  • Full suite green: bun test passes with no ce-work-beta SKILL.md reads.
  • Count assertion: getCompoundEngineeringCounts reports skills: 26.
  • Stale-install sweep still asserted: the ce-work-beta.md removal tests pass without touching the filesystem skill dir.
  • Converter transform still correct after the example swap (colon→dash output unchanged in behavior).

Verification: bun test green.

U4. Update README inventory and count

Goal
Keep the public inventory accurate.
Requirements
R4
Dependencies
None
Files
README.md
Approach & verification

Approach: Remove the | /ce-work-beta | ... | inventory row and change "currently ships 27 skills" to "26 skills".

Test expectation: none — documentation prose; no test asserts README contents (verified).

Verification: no ce-work-beta row remains; count reads 26.

U5. Decouple the best-practices doc

Goal
Preserve the delegation learnings as a standalone reference.
Requirements
R6
Dependencies
None
Files
docs/solutions/best-practices/codex-delegation-best-practices.md
Approach & verification

Approach: Keep the token-economics crossover (~5–7 unit threshold) and batching guidance. Remove or rewrite passages that frame the doc as ce-work-beta usage (references to the live skill, its config keys, the promotion path) so it reads as general external-delegation knowledge. Update frontmatter tags if they name the skill.

Test expectation: none — documentation.

Verification: the doc stands alone; no dangling references to ce-work-beta as a live skill.

U6. Delete the promotion checklist

Goal
Remove the now-moot promotion doc.
Requirements
R7
Dependencies
None
Files
docs/solutions/skill-design/ce-work-beta-promotion-checklist.md
Approach & verification

Approach: Delete the file. Grep docs/solutions/ for inbound links to it and fix any (likely none).

Test expectation: none — documentation.

Verification: file gone; no broken links to it.


Verification Contract

  • bun test — full suite green, including the repaired cleanup, conventions, converter, and release-metadata tests.
  • bun run release:validate — reports compound-engineering currently has 0 agents, 26 skills, ... and exits in sync (no metadata errors).
  • rg -n "ce-work-beta" . — the only surviving matches are historical files in docs/plans/, CHANGELOG.md history, and this plan document. No live skill, registry-absent reference, README row, or test reading the deleted SKILL.md remains.

Definition of Done

  • R1–R9 satisfied.
  • bun test and bun run release:validate both green; release:validate reports 26 skills.
  • No reference to ce-work-beta as a live skill anywhere except historical plan docs, CHANGELOG history, and this plan.
  • The best-practices doc reads standalone; the promotion checklist is deleted.
  • No abandoned or experimental code left in the diff; changes land in one PR with a chore(ce-work-beta): title via the standard PR flow (no direct push to main).
