is_available() only caught FileNotFoundError and TimeoutExpired. On WSL,
a /mnt/c/.../WindowsApps entry on $PATH returns EACCES during exec, and
Python raises PermissionError. That escaped is_available() and crashed
pipeline.diagnose() before any source ran.
Catch OSError instead. It covers FileNotFoundError, PermissionError, and
any other spawn-time OS error, so a non-executable xurl on PATH falls
through to the next backend instead of aborting the run.
bird_x.py and youtube_yt.py had four near-identical copies of the same
subprocess cleanup dance (Popen + os.setsid + communicate(timeout) +
SIGTERM via killpg + proc.kill() fallback + wait(5)). Extract to
lib.subproc.run_with_timeout(), which:
- runs the child in its own process group via os.setsid where available
- raises SubprocTimeout on timeout
- on timeout: SIGTERM the group, fall back to proc.kill(), wait up to 5s
- accepts an on_pid callback so bird_x can still register child PIDs
with last30days.register_child_pid for whole-process cleanup
- captures stdout/stderr as strings in a SubprocResult dataclass
Migrated call sites: _run_bird_search, search_handles inner worker,
search_youtube, fetch_transcript. With the helper in place, the signal
and subprocess imports became dead in both files (plus os in
youtube_yt) and went with them.
Tests: 9 new subproc tests cover success, non-zero exit, stderr capture,
timeout-raises, timeout-kills-group, missing-command, env passthrough,
PID callback, and callback-exception suppression. test_env_v3 and
test_youtube_yt patch subproc.run_with_timeout instead of the removed
bird_x.subprocess and yt-dlp subprocess.
1. N+1 queries in store.store_findings()
The old loop ran one SELECT per finding to check existence, then one
INSERT or UPDATE. 100 findings cost 200 serial SQLite roundtrips.
Now: one batch SELECT with WHERE source_url IN (...) builds a lookup
dict, then executemany() handles all inserts and updates. Query count
stays constant regardless of batch size. Benchmark on 500 findings:
~30ms to ~20ms; gap widens on slower storage.
2. O(n^2) source_items dedup in fusion.weighted_rrf()
Merging an item into an existing candidate ran any(existing.source ==
... for existing in candidate.source_items), linearly scanning a list
that grew with each merge. At 40 candidates with 20 source_items each,
fusion went quadratic. Now tracks (source, item_id) tuples in a
per-candidate set for O(1) lookup. The source_items list itself is
unchanged since other code iterates it.
3. Dead code removal
- providers.GeminiClient.ground_search() and .url_context_json(): zero
callers. Deleted.
- render._top_comment_excerpt(): zero callers. Deleted.
- env.is_reddit_available(): one-line wrapper around get_reddit_source.
Callers can check get_reddit_source(config) is not None directly.
Scoring hot path (_normalize_score_dedupe) re-tokenized the same
ranking_query ~240x per stream: once per item for local_relevance,
plus ~5x per item across snippet windows. Query tokens are immutable
within a stream, so compute them once as relevance.PreparedQuery and
thread through signals.annotate_stream and snippet.extract_best_snippet.
dedupe._PreparedText called normalize_text twice: once in __init__ and
again via get_ngrams. Factor out _ngrams_of_normalized so the prepared
path skips the redundant pass while get_ngrams keeps its public contract.
Behavior unchanged.
_normalize_reddit, _normalize_hackernews, and _normalize_github inlined
the same 5-line comprehension to stringify and space-join the first 3
top_comments' excerpt field. Extract one helper, call it from all three.
The comment field name varies per source (Reddit/GitHub use 'excerpt',
HN uses 'text'), so it's passed as a parameter. Behavior unchanged.
Three independent Opus 4.7 self-debugs on 2026-04-18 converged on the same
root cause of the v3.0.6/v3.0.7 canonical-compliance regression: SKILL.md is
42,860 tokens / 1,478 lines, LAWs lived at line 1094+, every realistic reading
strategy failed to reach them before synthesis.
Unit 1 - Moved the BADGE MANDATORY block and VOICE CONTRACT LAW 1-5 (plus
the formatting-authority preface) from line ~1090 to line ~75 (right after
the SKILL CONTRACT preface, before HOW TO INVOKE THIS SKILL). Every reading
strategy now lands the LAWs in active context before synthesis.
Unit 2 - Engine now emits the badge as the first line of --emit=compact
stdout. Passing through the script output becomes the default-correct
behavior; emitting the badge no longer depends on model compliance. Reads
version from .claude-plugin/plugin.json at runtime with graceful fallback.
Unit 3 - Deleted skills/last30days/SKILL.md stub (231-line v3-spec file).
This was the wrong-file-capture hazard Ron Conway's self-debug identified:
model grabbed the first SKILL.md find surfaced and treated it as
authoritative. Only ONE SKILL.md in the plugin package now.
Diagnoses verbatim:
- Kanye thread: "I read lines 1-600 in chunks, jumped to 300-899, then
stopped. File is 1478 lines. I never saw past ~900."
- Peter thread: "I tried Read once, hit the 25K token cap on a 42,860-token
file, and bailed instead of chunked-reading with offset/limit. I never
opened SKILL.md at all."
- Ron Conway thread: "I read one SKILL.md (231 lines)... the v3 spec stub.
I never opened the operational SKILL.md sitting next to the script."
Validation: direct engine invocation confirms badge at line 1 of compact
output. Module imports clean.

Adds commands/last30days.md so /last30days registers as a Claude Code
slash command for plugin users. Users type /last30days and autocomplete
prefix-matches to the canonical /last30days:last30days form (same as
/ce:plan resolving to /compound-engineering:ce-plan).
Removes skills/last30days-nux/, a byte-identical duplicate of the root
SKILL.md that created confusing /last30days:last30days-nux autocomplete
entries via Claude Code's plugin namespacing. Root SKILL.md remains
the canonical skill source; natural-language skill-selector invocation
is unchanged.
Recovery for users on v3.0.4: /plugin update last30days then /reload-plugins.
Closes#239 (path-escape error was already fixed in v3.0.4 by dropping
the rogue 'skills' key; v3.0.5 adds the slash command on top).
Supersedes #257 (suggested './' -> '.' workaround is obsolete since
v3.0.4 dropped the 'skills' key entirely, matching ecosystem standard).

Atomic bump across all four manifests:
- SKILL.md (root)
- skills/last30days/SKILL.md (internal spec)
- .claude-plugin/plugin.json
- gemini-extension.json
CHANGELOG entry documents the skill-upload packaging fix, vendor/ removal,
legacy plans/ removal, and the new scripts/build-skill.sh builder.
Two SKILL.md files declared `name: last30days` with `user-invocable: true`,
which caused strict marketplace validators to reject the plugin with "Some
plugins in this marketplace have validation errors":
- ./SKILL.md (canonical, also reachable via skills/last30days-nux/ symlink)
- ./skills/last30days/SKILL.md (v3 architecture spec, real file)
In v2.9.6, skills/last30days/SKILL.md was a symlink to ../../SKILL.md so
only one skill existed. Commit 0a9ff16 (v3.0.0) added a new real file at
skills/last30days-v3/SKILL.md, and commit 9be0780 then renamed that
directory to skills/last30days/, replacing the original symlink with a
different real file. The collision has been live since v3.0.0 shipped.
This change:
- Renames skills/last30days/SKILL.md to name: last30days-v3-spec and sets
user-invocable: false. The file stays in place as internal architecture
documentation, but it no longer competes with the canonical skill.
- Fixes README.md link that pointed to the deleted skills/last30days-v3/
path (left over from the rename).
- Removes a stale variants/open/SKILL.md reference (variants/open was
deleted in v3.0.0).
After the change, only one canonical name=last30days user-invocable=true
skill exists (the root SKILL.md, also reachable via the
skills/last30days-nux/ symlink, same inode).
Closes#204.

gemini-extension.json still referenced v2.9.5 and
skills/last30days-v3/SKILL.md still said 3.0.0-alpha.
Both now match pyproject.toml's canonical 3.0.0 version.
Addresses items from #190. Structural decisions (SKILL.md
consolidation, SKILL-original.md cleanup) left for maintainer.
This contribution was developed with AI assistance (Claude Code).
Add gemini-extension.json manifest with correct array-format settings,
symlink skills/last30days/SKILL.md to root SKILL.md for Gemini skill
discovery, add Gemini install paths to bash for-loop in both main and
open variant, and add Gemini CLI install instructions to README.
Incorporates the good parts of PR #53 (manifest, paths, README) while
avoiding duplicate SKILL.md, tool name scattering, and allowed-tools
pollution that would have created maintenance issues.
Closes#45
