pm init writes a malformed .gitignore entry that merges two paths into one line #514
Description
Summary
When pm initializes a repository-local tracker (.agents/pm) it appends runtime/cache ignore rules to .gitignore, but one generated line is malformed — it concatenates two separate ignore paths into a single line, so neither is actually ignored.
Observed .gitignore content (block written by pm init)
# PM CLI runtime and cache files
.agents/pm/runtime/
.agents/pm/search/
plus these individual lines:
.agents/pm/search/.agents/pm/runtime/metadata-cache-bodies.json <-- MALFORMED
.agents/pm/runtime/metadata-cache-collections.json
.agents/pm/runtime/history-drift-cache.json
The first individual line is two entries merged:
.agents/pm/search/(should ignore the whole search cache dir).agents/pm/runtime/metadata-cache-bodies.json(should ignore that one file)
Because they are concatenated as .agents/pm/search/.agents/pm/runtime/metadata-cache-bodies.json, the path does not exist and matches nothing.
Impact
metadata-cache-bodies.jsonis never ignored.- The primary runtime cache
metadata-cache.jsonis not covered by any effective rule (it is also missing from the explicit list), so in repositories that version.agents/pmevery pm command mutates tracked files, producing spurious git churn. - The blanket
.agents/pm/runtime/rule only protects untracked future files; already-tracked cache files stay tracked, so the merge/garble above is the actual root cause of the noise.
Expected behavior
pm should emit two clean, separate entries:
.agents/pm/search/
.agents/pm/runtime/metadata-cache-bodies.json
and should also explicitly list .agents/pm/runtime/metadata-cache.json (or rely solely on the .agents/pm/runtime/ blanket rule applied before the files are first tracked).
Steps to reproduce
pm init --workspace .(orpm initin a git repo) with an existing/empty.gitignore.- Inspect the pm-authored block in
.gitignore. - Observe the concatenated path on the
metadata-cache-bodies.jsonline.
Environment
- pm CLI: latest (10.x line)
- OS: Linux
- Reproduced in the simworld monorepo where
.agents/pm/runtime/metadata-cache*.jsonshow up as tracked modifications after normalpmcommands.

pm-hous— pm init writes a malformed .gitignore entry that merges two paths into one line #514: pm init writes no .gitignore rules — runtime/search caches churn as tracked files in downstream reposunbraind commentedon Jul 12, 2026
Resolved in merged PR #520: pm init now reconciles a canonical fenced workspace .gitignore block for runtime/search caches, repairs malformed content, remains idempotent, and handles nested invocation correctly.
