{"base":"main","body":"## What\n\nFixes #68: `grep_search`'s `max_results` was implemented as a `| head -n N` pipe, which caps **raw output lines** instead of **matching lines**. With `context_before`/`context_after`, a single match spans several lines (match + context + `--` separators), so `head` silently dropped matches — e.g. `max_results=10` with `-A 2` returned only 3 full matches plus a truncated 4th.\n\n## Changes\n\n- **`internal/tools/grep_search.go`**\n  - Replaced the `head -n` pipe with grep's native `--max-count=N`, which stops a file after N *matching* lines (still emitting their trailing context).\n  - Updated the `max_results` description: it now says \"per file\" (that's how grep counts with `--max-count`), and drops the false \"0 means no limit\" claim — 0 is the unset sentinel that maps to the default of 100, and passing 0 to `--max-count` would make grep stop immediately without reading input.\n  - Updated the now-stale comment about the pipeline's exit status (without the pipe, a grep failure like a bad regex surfaces directly as a non-zero exit with its stderr diagnostic).\n- **`internal/tools/tools_test.go`**\n  - Updated the two tests that asserted the old `| head -n 100` suffix.\n  - Added `TestGrepSearchLimitsMatchesNotLines` (custom `max_results` → `--max-count=5`, no `head` in the command) and `TestGrepSearchDefaultMaxResults` (omitted → `--max-count=100`).\n\n## Verification\n\n- `go build ./...`, `go vet`, and the full `go test ./...` suite pass.\n- Manual check against real grep: with `-A 2` and 5 matches in a file, the old `head -n 10` returned 3 matches (4th truncated); `--max-count=2` returns exactly 2 matches with full context, exit 0.\n\n## Note\n\n`--max-count` is inherently **per-file** (that's grep's semantics), so a recursive search across many files can return up to N matches *per file*. That's the behavior the issue asked for; if a strict global cap is ever wanted, it would need post-processing in Go rather than a shell flag.","head":"issue-68-greg","title":"grep_search: cap matches with --max-count instead of head -n"}

{"body":"Fixed — PR is up. Replaced the `| head -n N` pipe with grep's native `--max-count=N`, as suggested.\n\n**What was wrong:** `head -n` caps raw output *lines*. With `context_before`/`context_after`, one match spans several lines, so the limit silently dropped matches — I verified against real grep: with `-A 2` and 5 matches, `head -n 10` returned only 3 full matches plus a truncated 4th. `--max-count` stops a file after N *matching* lines (still emitting their trailing context), which is the promised semantics.\n\n**Also fixed while in there:**\n- The `max_results` description claimed \"0 means no limit\", but 0 is the unset sentinel that maps to the default of 100 (and passing 0 to `--max-count` would make grep stop immediately without reading anything). The description now says \"per file (default: 100)\" — per file because that's how grep counts with `--max-count`.\n- A stale comment about the pipeline's exit status being `head`'s; without the pipe, a grep failure (e.g. bad regex) surfaces directly as a non-zero exit with its stderr diagnostic.\n\n**Tests:** updated the two tests asserting the old `head` suffix, added `TestGrepSearchLimitsMatchesNotLines` and `TestGrepSearchDefaultMaxResults`. Full `go test ./...` passes.\n\nOne caveat worth knowing: `--max-count` is per-file by grep's design, so a recursive search can return up to N matches *per file*. If you ever want a strict global cap, that would need post-processing in Go rather than a shell flag — happy to do that as a follow-up if you'd prefer."}
