* chore: retire the Everything Claude Code name, ECC only
Replace the expanded product name and the everything-claude-code slug
with ECC across READMEs, translated docs, harness folders, skills,
commands, scripts and examples. Repo URLs now point at affaan-m/ECC.
Rename repo-internal artifacts to ecc forms (ecc-conventions skill,
ecc-guardrails, ecc-research-playbook, ecc-team-config, ecc-instincts
with ecc-* ids) and update .claude/ecc-tools.json.
Legacy install ids, plugin dirs, package names and MCP prefixes stay
where existing installs resolve against them. The codex global-state
check and harness-audit repo detection accept the new name first and
the legacy one as a fallback. The Discord bot prefers ~/GitHub/ECC and
falls back to the nested legacy checkout path.
Refresh the skill-triggers registryDigest for the changed skill text.
* fix(ecc-tools): drop managed paths to the removed Claude repo skill
.claude/skills/<repo-skill>/SKILL.md was deleted in #2770 but stayed listed in
ecc-tools.json and the team config. Remove those entries and point the Claude
Code adapter at the existing .agents/skills/ecc-conventions/SKILL.md.
Address review: the frontmatter guard only rejected the `everything-claude-code:`
prefix, so a hypothetical future `<other-plugin>:agent` value could slip through.
opencode registers its inline agents unscoped, so assert the id carries no `:` at
all — rejecting the whole scoped class — alongside the existing
registered-agent-map membership check.
The `.opencode/commands/*.md` frontmatter referenced agents with the Claude
Code plugin namespace (`agent: everything-claude-code:<name>`), but ECC's
opencode integration registers its agents unscoped in `opencode.json`'s
`agent` map (`code-reviewer`, `planner`, ...), and that file's own `command`
section already references them unscoped. The `everything-claude-code:` scope
resolves under no opencode config (the opencode plugin package is
`ecc-universal`, and inline-config agents are bare), so subtask commands like
`/code-review` hard-fail with `Agent not found: everything-claude-code:code-reviewer`.
Non-subtask commands fall back to the default agent and appear to work — which
is why only some commands failed.
Strip the `everything-claude-code:` prefix from all 30 command frontmatter
agent ids so they match the registered agents, fix the MIGRATION.md example,
and replace the test that enforced the broken scoped invariant with one that
asserts each command agent id is a registered opencode agent (fails on the old
scoped ids, passes on the fix).
Fixes#2477
