discoverTemplates() scans subdirectories for SKILL.md.tmpl files but
only skips node_modules, .git, and dist. Hidden directories like
.claude/, .agents/, and .codex/ (which contain symlinked skill
installs) were being scanned, allowing a malicious .tmpl in a
symlinked skill to inject into the generation pipeline.
Fix: add !d.name.startsWith('.') to the subdirs() filter. This skips
all dot-prefixed directories, matching the standard convention that
hidden dirs are not source code.
SKILL, OUTCOME, SESSION_ID, SOURCE, and EVENT_TYPE values go directly into printf %s for JSONL output. If any contain double quotes, backslashes, or newlines, the JSON breaks — or worse, injects arbitrary fields. Fix: strip quotes, backslashes, and control characters from all string fields before JSONL construction via json_safe() helper.
gstack-review-log appends its argument directly to a JSONL file with no validation. Malformed or crafted input could corrupt the review log or inject arbitrary content. Fix: validate input is parseable JSON via python3 before appending. Reject with exit 1 and stderr message if invalid.
Codex-generated skills hardcoded a Claude co-author trailer in commit
messages. Users running gstack under Codex pushed commits attributed
to the wrong AI assistant.
Add {{CO_AUTHOR_TRAILER}} resolver that emits the correct trailer
based on ctx.host:
- claude: Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- codex: Co-Authored-By: OpenAI Codex <noreply@openai.com>
Replace hardcoded trailers in ship/SKILL.md.tmpl and
document-release/SKILL.md.tmpl with the resolver placeholder.
Fixes #282. Fixes #383.

When a just-upgraded-from marker persists across sessions, the update check would write UP_TO_DATE to cache and exit immediately — never fetching the remote VERSION. Users silently miss updates that landed after their last upgrade. Remove the early exit and premature cache write so the script falls through to the remote check after consuming the marker. This ensures JUST_UPGRADED is still emitted for the preamble, while also detecting any newer versions available upstream. Fixes #515
The build script chains gen:skill-docs and bun build --compile with &&, so a doc generation failure (e.g. missing Codex host config, template error) prevents the browse binary from being compiled. Users end up with a broken install where setup reports the binary is missing. Replace && with ; for the two gen:skill-docs steps so they run independently of the compilation chain. Doc generation errors are still visible in stderr, but no longer block binary compilation. Fixes #482

Never passed reliably. Tests ambiguous routing ("think bigger" →
plan-ceo-review) but Claude legitimately answers directly instead
of invoking a skill. The other 10 journey tests cover routing
with clear, actionable signals.
