📝 Walkthrough

The CLI adds a command for retrieving bounded source ranges from pinned commits. In JSON mode, code-search results can include bounded source context for matches. Non-JSON search output remains unchanged. Tracking redacts repository, commit, and file values.

Changes: Pinned Source Context

Layer / File(s) Summary
Validate and slice pinned source
comfy_cli/command/code_search.py, tests/comfy_cli/command/test_code_search.py
Pinned-source retrieval validates the repository, commit, path, and line range. It limits file and snippet sizes, enforces a request deadline, and returns scrubbed source text with a pinned GitHub URL. Tests cover validation, slicing, sanitization, and fetch handling.
Attach context to JSON search results
comfy_cli/command/code_search.py, tests/comfy_cli/command/test_code_search.py
In JSON mode, code search attaches bounded source snippets to matches. Missing commits, stale previews, fetch or range failures, and omitted snippets produce per-match errors. Tests cover fetch limits and stale-preview handling.
Expose pinned range retrieval
comfy_cli/command/code_search.py, comfy_cli/cmdline.py, comfy_cli/error_codes.py, comfy_cli/tracking.py, tests/comfy_cli/test_tracking.py
The code-search-context command returns a requested pinned source range as JSON or text. Invalid arguments exit with code 2; source retrieval failures exit with code 1. The root CLI registers the command lazily, and tracking redacts repository, commit, and file values.

Duplicate error guidance and a narrow stale-file case remain. The latter can abort a JSON search; fix both before merge if practical. Failed context fetches are now capped.

Review comments at @comfy_cli/command/code_search.py:
- Line 708: Update the source display at console.print(snippet["text"]) to wrap
the untrusted text in a Rich Text object before printing, matching the
search-result preview renderer so source markup is displayed literally.
- Line 259: Update the source-line splitting in the code-search flow at
`source.splitlines()` to count only `\n` line breaks, handling a trailing
newline explicitly so U+2028 does not shift the pinned range’s line numbers.
- Line 289: Update _attach_context to bound source-fetch attempts independently
of successful attachments, so failed fetches cannot trigger requests for every
match; also reuse fetched-file results for matches sharing the same repository,
commit, and path. Keep MAX_CONTEXT_FILES as the attempt limit.
- Line 243: Update the source-fetch streaming loop around response.iter_content
to enforce a monotonic total deadline, following the deadline behavior in
_fetch_results; stop consuming and abort the fetch when the deadline expires,
even if the response keeps delivering data below the 1 MiB cap.
- Line 274: Update _strip_control_chars or the source-snippet assembly so
sanitization preserves newline separators, keeping multiline snippets readable
and representative of their pinned lines. Add a multiline text assertion to the
slice test to verify the returned snippet retains its line breaks.

christian-byrne added a commit that referenced this pull request Oct 17, 2026
`build / Run tests` is red on #1017 at its exact head: `code-search-context`
emits `bad_args` and `context_unavailable` as JSON envelope codes, and
`tests/comfy_cli/output/test_error_code_registry.py` enforces that every code
raised anywhere under `comfy_cli/` appears in `error_codes.REGISTRY`. It reads
`"code": "..."` out of dict literals, which is exactly how those two are
written. 1 failed, 10107 passed.

The names are load-bearing and are not changed: cloud's `search_code` adapter
reads `error.code` off this envelope and its tests assert both strings, so
renaming either would break that contract to satisfy a registry it can simply
be added to.

Each entry carries a navigation hint, as `test_every_error_code_is_a_navigation_signal`
requires, and says what the caller should do next — for `context_unavailable`
that is to continue from the bounded window already on the match rather than
retry, since the search hit itself is still good.

Found while measuring this surface for localvibe-56; #1017's hosted checks were
still running when it was written up, so nobody had seen this yet.

Implemented the ten pinned-context review findings in 33528b5:

  1. Added a total streaming deadline.
  2. Preserved snippet newlines by sanitizing each source line before joining.
  3. Capped fetch attempts, including failed attempts, at MAX_CONTEXT_FILES.
  4. Rendered fetched source as literal Rich Text.
  5. Counted source lines using \n only.
  6. Redacted repository, commit, and file from command analytics.
  7. Refused to attach context when the pinned line no longer matches the indexed preview.
  8. Closed streamed responses on success and every early error path.
  9. Rejected repository owner/name segments made only of dots.
  10. Sent X-Comfy-Code-Search-Origin only for attributed agent calls.

The code-search and tracking tests pass locally (287 tests), along with repository lint, format, and package-build checks. Exact-head CI is running now.

🟡 Minor · Keep out-of-range context failures per match. · code_search.py:358

comfy_cli/command/code_search.py:358
🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Keep out-of-range context failures per match.

When a match line is beyond the pinned file but its context start is valid, _source_slice returns an EOF-truncated snippet. The source-line lookup then indexes past that snippet outside the try, so IndexError aborts the JSON search instead of setting context_error.

Suggested fix
             try:
                 snippet = _source_slice(
                     result["repository"], commit, result["file"], start, end, agent_origin=agent_origin
                 )
+                source_line = snippet["text"].split("\n")[match["line"] - snippet["start_line"]]
+                if source_line.rstrip() != match["preview"]:
+                    match["context_error"] = "context unavailable: pinned source does not match indexed preview"
+                    continue

                 match["context_error"] = f"context unavailable: {type(exc).__name__}"
                 continue
-            source_line = snippet["text"].split("\n")[match["line"] - snippet["start_line"]]
-            if source_line.rstrip() != match["preview"]:
-                match["context_error"] = "context unavailable: pinned source does not match indexed preview"

Comment thread comfy_cli/error_codes.py
An earlier fixup commit registered bad_args/context_unavailable under
the pre-rename command text (`comfy code-search context`) before the
command became the standalone `code-search-context`. #1019 added the
correct pair but left the stale one in, so test_no_duplicate_codes
failed CI.

Resolved the last open thread (duplicate bad_args/context_unavailable registration): fixed by 6273c55 ("drop the duplicate context error codes"), which removed the stale pre-rename registration and is why test_no_duplicate_codes now passes. Exact head 6273c55 is green on all 18 required checks; 0 unresolved threads remain. Still waiting on greenlight bot re-evaluation (it last commented at 07:22Z, against a head two pushes stale) — not retriggering the label per the one-shot rule.

…dary

A snippet truncated at EOF could put match["line"] - snippet["start_line"]
past the end of the split text, raising IndexError outside the try block
around _source_slice and aborting the whole JSON search instead of
recording context_error for that one match.
