skill-frontmatter's files: pattern matched any SKILL.md, so it ran twice per
sync -- once on the .apm/ source and again on the compiled flat-mirror copy.
Scoped it to .apm/skills/ like its sibling hooks (skill-size-check,
vale-audit-prefilter-skill), which already only check the source.
sync-plugin-content.sh ran `apm pack` once per plugin, serially -- each
invocation is dominated by fixed CLI startup cost rather than per-plugin
work, so 6 plugins paid that cost 6 times over (~3.1s). Backgrounds the
per-plugin work instead, buffering each plugin's output so concurrent
DRIFT/FAIL messages can't interleave, then flushes in stable order after
`wait` (~1.3s, confirmed idempotent on a real sync).

apm pack silently skips regenerating plugin.json when it already exists
("already exists; skipping plugin.json generation. Re-run with --force to
overwrite it."). sync-plugin-content.sh never passed --force, so
.claude-plugin/plugin.json and .github/plugin/plugin.json were written
once on first sync and never refreshed again -- a name/version/description
edit in a plugin's apm.yml would silently stop propagating, with no gate
catching it (check-manifests.sh only checks presence; check-plugin-content-
sync explicitly excludes plugin.json; apm-pack-check-clean is scoped to
marketplace.json only).
Pass --force on real-mode syncs only (--check must not mutate the plugin
root, so plugin.json staleness there stays a known, undetected gap until
the next real sync -- documented in the script's header comment).
Regenerating surfaced a second, unrelated bug: apm's writer and
pretty-format-json's --autofix disagree on JSON key order (semantic vs.
alphabetical), so every real sync would otherwise flip plugin.json's key
order right back after a commit re-alphabetized it. Excluded the four
apm-generated manifests (plugin.json x2, marketplace.json x2) from
pretty-format-json -- their exact formatting is dictated by apm's own
writer as compiled output, not this repo's generic JSON prettifier.
Verified idempotent: a second real sync after this fix produces zero
further diff.

Claude Code's (and Copilot's) native plugin installer has zero awareness of
.apm/ nesting -- it convention-scans only flat skills/, agents/, commands/,
hooks.json at each plugin's root. Confirmed via strings on the installed
claude binary and live installs of git@holocron/gitea@holocron/kyberforge@
holocron, all reporting Skills(0) Agents(0) Hooks(0) post ADR-0015's apm
conversion. Root cause (apm_cli/core/plugin_manifest.py): apm's plugin.json
compiler deliberately strips skills/agents/commands keys, assuming the host
already auto-discovers those convention directories -- it has no model of
.apm/ being host-visible at all. Separately, apm's own bundle exporter
(apm_cli/bundle/plugin_exporter.py, behind `apm pack --format plugin`)
implements the correct .apm/ -> flat mapping, but only ever targeted
build/<name>-<version>/, a path nothing in marketplace.json's source: points
at.
scripts/sync-plugin-content.sh wraps that bundle exporter and copies its
agents/, skills/, commands/, instructions/, extensions/, and merged
hooks.json back into each plugin's own root as a second tracked
compiled-output category -- same governance status as
.claude-plugin/plugin.json: generated from .apm/, never hand-edited. tests/
subdirectories are excluded from the mirror (dev fixtures, not host-visible
runtime content; several hardcode a relative repo-root walk-up sized for the
.apm/-nested depth, which breaks when duplicated one level shallower).
Applied for real across all 6 plugins and verified two ways: `claude plugin
validate --strict` passes on every real plugin directory, and a live
`claude --plugin-dir <path> -p "list skills/agents"` behavioral test
confirms content is now actually discovered.
Also, from the same issue #90 review round:
- scripts/check-manifests.sh pointed at each plugin's root-level plugin.json
(checking skills/hooks/mcpServers/agents pointer fields) -- that file was a
stale near-duplicate of .claude-plugin/plugin.json nothing else read or
wrote, now deleted across all 6 plugins. check-manifests.sh is rewritten to
validate .claude-plugin/plugin.json instead, and drops the pointer-field
checks entirely (nothing to check -- those fields are correctly absent by
design). Content-presence drift is now check-plugin-content-sync's job, a
new pre-push hook wired in .pre-commit-config.yaml.
docs/adr/0017 records the root cause and decision in full, including two
rejected alternatives (patching plugin.json's path fields directly -- apm's
compiler strips them on every run; pointing marketplace.json at apm pack's
build/ output -- a version-suffixed non-source directory nothing can install
from without an extra build step). ADR-0015 and CONTEXT.md are updated to
point at it.
