fix: close four review findings from #41 (0.7.2) - #43
Merged
Conversation
Four findings landed on #41 after it was merged. Each was checked against the code rather than taken on trust; all four held. **A repository name could carry instructions into Tier 1.** `currentRepo` is `basename(git rev-parse --show-toplevel)` — a directory name, which on POSIX may contain newlines and arbitrary prose. That value was interpolated into the description loaded into every conversation, and `writeSkillDescription` only JSON-quotes the line, which keeps the YAML valid and does nothing about the content. Clone into a chosen directory name and the text is in front of the model on every turn. The exposure predates the capture nudge: `buildDigest` has interpolated repo names for many releases. `safeRepo` closes it in one place for both, constraining to `[A-Za-z0-9._-]` and 64 characters. Display only — every query still matches on the real name, because a repository whose notes stopped being found would be worse than the bug being fixed. **The recent-capture list was unbounded.** `write --from-json` takes an array and `import` exists, so one bulk write stamps every note with the same minute and the next brief printed all of them — spending the context the brief exists to conserve, while reading as the whole list. That is the silent truncation the tree already refuses to make. Now capped at `briefRecentIds` with the remainder counted and stated. **ARCHITECTURE.md said Tier 2 fires "only when recall fires".** It fires for remember too, as `brief` — added in the same PR that left the label alone. **A test was time-bombed.** It pinned `now` to 2027-01-01, and `recentlyCaptured` filters `updated >= cutoff` with no upper bound, so the assertion stops holding once the calendar passes that date. Derived from `Date.now()` instead. 108 tests, up from 106. Zero dependencies.

Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to This PR sanitizes repository labels and bounds recent-capture output, but repository-controlled text can still preserve instruction-like content in generated assistant descriptions, with one scoped output path bypassing the sanitizer; fractional briefRecentIds values can also make brief fail. The remaining security exposure is high-impact and should be fixed before merge. Sequence Diagram(s)sequenceDiagram

…ractional cap broke brief Two more findings on #43, both confirmed against the code before fixing. **The charset filter was not enough.** `safeRepo` allowed `[A-Za-z0-9._-]`, which is exactly the charset a GitHub repository name is drawn from — so `SYSTEM-ignore-previous-instructions` survived it unchanged and arrived by nothing more exotic than `git clone`. Hyphens separate words as well as spaces do. Shape decides instead: a repository name is one to three segments and short, an instruction needs more words than that. Anything else renders as a stable `repo-<hash>`, which still distinguishes one repository from another and still tells a reader in the wrong tree that the numbers are not theirs — the only job the name had. A legitimate four-segment name pays for that, deliberately. Filtering also must not be able to *make* a name look ordinary: stripping the spaces out of "Ignore previous instructions" collapses it into one plain token that would have passed the shape test. A name that had to be modified at all is already outside the shape. **A fractional cap threw.** `loadConfig` accepted any positive finite number, and `briefRecentIds` is bound into SQLite's `LIMIT ?`, which answers `datatype mismatch` rather than rounding — verified, not assumed. Every cap in DEFAULTS counts something, so `loadConfig` now requires a safe integer. The floor also lives at the use site, because callers may pass a cfg that never went through `loadConfig`, and every test does exactly that. 109 tests, up from 108.

Four CodeRabbit findings landed on #41 after it was merged. Each was verified against the code rather than taken on trust; all four held.
🟠 A repository name could carry instructions into Tier 1 (CWE-1427)
currentRepoisbasename(git rev-parse --show-toplevel)— a directory name, which on POSIX may contain newlines and arbitrary prose. It was interpolated into the description loaded into every conversation.writeSkillDescriptiononly JSON-quotes the line, which keeps the YAML valid and does nothing about the content.Being precise about scope: this predates the capture nudge.
buildDigesthas interpolated repo names intorecall's description for many releases. 0.7.0 widened the surface to a second description; it did not create the hole.safeRepocloses it in one place for both.Display only. Every query still matches on the real name — a repository whose notes stopped being found would be a worse bug than the one being fixed.
🟠 The recent-capture list was unbounded
write --from-jsontakes an array andimportexists, so one bulk write stamps every note with the same minute and the nextbriefprinted all of them. That spends the context the brief exists to conserve, while reading as the whole list — the exact silent truncation the tree already refuses to make.Now capped at
briefRecentIds(default 10), with the remainder counted and stated:One row past the cap is the overflow probe; the exact count costs a second query only when there is something to report.
🟡 ARCHITECTURE.md Tier 2 label
