- New services/truncate.ts. Tmpfs storage at /tmp/boocode-truncations/
(BOOCODE_TRUNCATION_DIR env var overrides for tests). 12-char base32
opaque ids (~60 bits entropy, "tr_<id>"). Three exports: storeTruncation,
readTruncation, truncateIfNeeded (wrap-or-passthrough helper).
cleanupTruncations does TTL-pass (7 days) + orphan-reap (parts query on
payload->'output'->>'outputPath') in one shot.
- Wired four tools through truncateIfNeeded: view_file (raw full file),
list_dir (full filtered+secret-filtered entries serialized one-per-line),
web_fetch (textRaw pre-slice), codecontext_client (body.result pre-slice).
Each returns the existing sliced view plus an optional outputPath field
when truncation fires.
- New view_truncated_output ToolDef. Resolves opaque id → on-disk content
internally; model never sees the truncation dir. Same start_line /
end_line slicing semantics as view_file. Registered in ALL_TOOLS (alpha
sort places it after view_file automatically) and READ_ONLY_TOOL_NAMES.
- cleanupTruncations piggybacks on the v1.13.3 stuck-row sweeper's 60s
setInterval. No-op when truncation dir is empty.
Not wired (TODO follow-up): grep and find_files. file_ops returns post-cap
results to the tool execute path, so the "full content" isn't recoverable
without a refactor of fileOps.grep / fileOps.findFiles to expose the
uncapped result. web_search is silent-slice (no truncated flag); outside
scope. Five sites of seven covered; the remaining two are the only ones
needing a file_ops change.
Tests: 7 new in truncate.test.ts (roundtrip, unknown id, malformed id,
truncateIfNeeded false/true/over-cap/storage-failure paths). 186 total
(was 179). cleanupTruncations file-system half implicitly via TTL pass;
orphan-reap branch covered by the live container smoke.
Smoke verified end-to-end against the live container:
- view_file with start_line=1, end_line=3 on CLAUDE.md → tool_result part
carried outputPath "tr_cdpn1o04k6ma" + truncated=true.
- /tmp/boocode-truncations/tr_cdpn1o04k6ma exists, 15876 bytes, mode 0o600,
parent dir mode 0o700.
- Follow-up view_truncated_output(id, start_line=50, end_line=55) returned
the actual lines 50-55 of CLAUDE.md (the 808notes/BooCode bullets).
- ALL_TOOLS count=20 (was 19); alpha sort places view_truncated_output
between view_file and watch_changes.
Closes a v1.12 catalog row that was scoped but deferred. The v1.13 parts
table made outputPath ride on the existing tool_result payload with no
schema change beyond the storage helper itself.
