Agent Plugins 0.8.0

• Fix Connector readiness evaluation for Claude Bash/command and Codex
  exec_command/cmd traces. A shared Rust command checker runs alongside AEP's session checks
  in replay and live CI; parsed help commands no longer count as mutations. Regression cases
  reject real mutations, missing doctor evidence, and mutations chained after help.

• Publish the connectors plugin in the release-pinned installation guides for both hosts.

• Repair YAML quoting in the ESS skill description so every released plugin validates.

• Add the focused connectors plugin to both marketplaces, with one shared skill for the
  Connectors 0.6.0 CLI, secret-safe onboarding, readiness diagnostics, and governed operation
  invocation. Include host installation guidance and a readiness eval case.

• The planning skill says how to take an edge back. AEP 0.53.0 adds
  aep plan artifact unrelate <id> <relation> <target>, and the skill now names it in the write-verb
  list, in guardrail 2, in the mutation-ownership table and in the renaming paragraph. Until this
  landed the skill described a store where a relation could be added and never removed, so a session
  that made a backwards blocks edge had nowhere to put the correction but the artifact's body —
  which is what a recorded run did on 2026-09-04. A refusal naming unrelate as an unknown verb now
  means the installed CLI predates 0.53.0, and the skill says so.

• Every authored document teaches the grouped CLI spelling. AEP 0.52.0 replaced a flat first
  level of twenty-three verbs with four areas plus doctor, and ESS 0.12.0 replaced twenty with
  four;
  both keep every flat spelling as a hidden alias with identical stdout, stderr and exit status, so
  nothing here was broken and nothing is fixed — what changes is what a skill, a charter, a
  reference, a page and an eval case teach a reader to type.

  was	is
  aep validate resolve inspect evaluate explain describe schema workflow	aep govern <verb>
  aep artifact serve entity audit workspace conformance reverse	aep plan <verb>
  aep eval {matrix,run}	aep drive eval {matrix,run}
  aep trace contract property specification evidence	aep observe <verb>
  ess validate compile compose inspect graph realization runtime	ess specify <verb>
  ess synthesize project schema build release stack deployment	ess generate <verb>
  ess conform diff impact	ess verify <verb>
  ess import	ess infra import

  aep drive run|status|resume|transition, aep doctor and ess generate --path … are what they
  were: those verbs did not move. The protocol spelling follows aep's, since they are two names
  for one binary.

• The eval corpus's command matchers accept either spelling rather than moving to the grouped
  one. '(aep|protocol) artifact +move' is now '(aep|protocol) +(plan +)?artifact +move': the
  committed transcript of golden-path-end-to-end was recorded under the flat spelling and a row
  that stopped matching it would be a specification describing a run other than the one recorded,
  while a row that only matched the flat spelling would report never_occurred against the next
  recording made by an agent reading the migrated skills. Widening witnesses a claim; it does not
  widen one. The same holds for the tool.absent row in adversary-tests-only, where accepting
  both spellings is what keeps "no artifact command ran" from being satisfiable by typing the
  other one.

• agentplugins-check refuses a flat spelling in any .md, .yaml or .yml this repository
  authors, rather than leaving AGENTS.md § Invariants to a person remembering to grep. Sweeping
  the tree found 360 of them across 47 files, five of which were in a file no hand list had — the
  paid eval workflow.

  The sweep exempts four prefixes, each visible in a diff:

  exempt	why
  CHANGELOG.md	what a command was called
  changes/	a dated record, written on the day
  .engineering/	the planning store, whose only writer is the aep CLI
  .github/workflows/	a program, not a lesson: eval.yml pins AEP_VERSION: '0.44.0', so its spelling has to be the surface that version has

  Rust sources are not swept for the same reason as the last row: evals.rs spawns
  aep eval run --stream against whichever binary is on PATH, and that call is a call.

• The install page pins AEP 0.52.0 and ESS 0.13.1, the latest published release of each, and
  the versions whose --version lines it quotes. The grouped spelling the pages now teach exists in
  AEP from 0.52.0 and in ESS from 0.12.0; the previous pins (0.51.0 and 0.11.1) have neither.
