feat: store and index tool inputs and results - #79
Merged

Conversation
Issue #28 settles what ccvault keeps of a tool call: inputs whole and indexed, non-bulk results whole and indexed, bulk file reads and image payloads reduced to a length. The decision has to be identical for all five sources, and the code that extracts payloads is split between pkg/parser (claude-code, nanoclaw) and the individual adapters (codex, jeff) with no shared layer underneath, so the policy gets its own package rather than being written twice. Re-measured against the whole 965,061-turn archive rather than the 2,824-block sample the issue was specified from. The sample held up on the question that mattered — nothing non-bulk comes near a size that needs capping — but got the proportions wrong, so the constants and comments here carry the full-corpus numbers: inputs 259,836 calls 78.6 MB p50 72 B max 99,792 non-bulk result 211,892 results 397 MB p50 525 B max 51,557 bulk file reads 47,444 results 205 MB max 67,313 image payloads 476 results 54.9 MB max 512,497 The 128 KB backstop is confirmed as a backstop: not one of the 211,892 non-bulk results exceeds even 64 KB, so it fires on nothing that exists and exists only for the tool nobody has classified yet.

… dropping them pkg/parser had every tool call's input in hand and used it for one thing — extracting a file path — then let it go. Tool results it recognised only to set a has_error flag. models.ToolUse had nowhere to put either, and adapter.ParsedToolUse was two fields wide. ExtractToolUses now runs two passes, because a call and its result live in different turns: Claude Code writes the tool_use into an assistant message and the tool_result into a later user message, joined by tool_use_id. Pairing by position would cross results from one turn's concurrent calls, which real transcripts produce. How the five sources express the link, checked against real data rather than inferred from the adapters: claude-code content block id "toolu_…"; result block tool_use_id nanoclaw identical — same JSONL, same parser codex payload call_id on both halves, for two tool shapes jeff data.tool_id on both halves, EMPTY on 633 of 742 requests hex no tool calls at all; messages are role/content/timestamp Jeff's mostly-empty tool_id is why it links by order instead: keying on an id would collapse 85% of its calls onto each other. Its files pair requests and results one for one, so the oldest unanswered call is a sound fallback, and an exact tool_id match still wins when jeff recorded one. Codex's custom_tool_call is now recorded. The adapter skipped that payload kind outright, which meant apply_patch — codex's edit tool — left no trace in the archive at all. It is wired here rather than filed separately because its output half is one of the two payload kinds this change has to start reading, and leaving one of a symmetric pair unhandled is harder to explain than handling both. The three places that copy these fields — two adapters and the sync layer — go through one conversion pair in pkg/adapter rather than nine field assignments each, and a reflection test walks the structs so a field added without being threaded through fails. That is the failure shape from PR #35: compiles, lints clean, carries the wrong data. turns.content is deliberately untouched. models.UserContentBlock.Content is typed as a string, so a turn carrying an array-valued tool_result fails the whole content unmarshal and stores "" — which is how image base64 has been kept out of turns_fts, accidentally. Retyping that field would rewrite turns.content for a third of the archive, so the new payloads reach search through their own index instead. Filing the accident separately.

… raw_json Six columns on tool_uses — tool_use_id, input_json, input_length, result_content, result_length, result_omitted_reason — plus tool_uses_fts over the two that hold stored text. On tool_uses rather than a new table: the relationship is 1:1, the row already carries turn_id and session_id, and a join table buys nothing. Its own FTS table rather than folded into turns_fts, because the material belongs to a tool_uses row and there is no turns column it could live in without being duplicated there. result_length carries two facts, which is why there is no has_result column: NULL means nothing ever answered the call, 0 means it answered with nothing. A second column would say the same thing twice and could disagree with itself. idx_tool_uses_tool_use_id is deliberately not unique. The provider id is stored verbatim so a follow-up can join it against the toolUseId in a subagent's meta.json (#31), and a unique index would be a hazard rather than a guarantee: one transcript ingested under two sources legitimately repeats an id, and #29 found INSERT OR REPLACE resolves a unique conflict by silently deleting the conflicting row. Backfilled from turns.raw_json, so an existing archive upgrades instead of re-ingesting 44,840 sessions. The join is per turn by position — the Nth tool_uses row by rowid to the Nth tool_use block by array index — with tool_name required to agree so a bad match stays NULL rather than being labelled with another call's input. Measured end to end against a copy of the author's 965,061-turn, 261,138-tool-use, 5,057 MB archive: migration 009 total 2m26s, +665 MB payload columns 442 MB (74 MB inputs, 368 MB results) tool_uses_fts 130 MB over 261,138 documents rows given an id and input 259,836 of 261,138 results stored whole 211,869 (378 MB of original) results omitted: bulk_read 47,444 (195 MB) results omitted: image 476 (52 MB) results omitted: oversize 0 results omitted: undecodable 0 The 128 KB backstop fired on nothing, which is what a backstop should do. The 1,302 rows left without an id are all duplicates: 1,288 turns in that archive carry more tool_uses rows than their message has tool_use blocks, left behind by the #30 recovery import. Filling the first and leaving the extras NULL is the right outcome — two rows sharing a provider id would make the id useless as a join key. The FTS table and its triggers are created after the backfill UPDATEs and populated with one rebuild, so the full-table update pays no per-row index cost. Triggers are scoped to exactly input_json and result_content, the two indexed columns; migration 008 measured a wider scope costing 377 MB of dead segments. The docsize shadow table ends with exactly 261,138 rows — no orphans, checked the way #42 established is the only way to see one. TestMigrator_BootstrapPartial simulated "only the initial schema" with a turns table missing raw_json and no tool_uses table at all, neither of which migration 001 omits. It bootstraps the database to version 1, which asserts everything 001 creates is present, so the fixture now creates it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
A text query now matches against tool_uses_fts as well as turns_fts, so the command you ran and the error a tool printed are findable. That was the point of issue #28: the turn that issued a call summarises itself as "[Tool: Bash]" and holds none of the command, so the material existed in the archive and was unreachable by search. Driven off a UNION of turn rowids rather than two outer joins with an OR between them. Each index answers a MATCH with a small set, so joining turns to that set is an index lookup, where an OR across outer joins would make the planner scan all 965,000 turns. UNION also collapses a turn whose content and several of whose payloads matched into the one row the caller asked for. The payload lookup is applied to the page, not to the candidates. SQLite evaluates result-column subqueries while feeding the sorter, which is before LIMIT, so selecting them alongside the page would run two correlated lookups for every row a common word matched — tens of thousands — to use twenty. Results carry matched_tool_name, and the snippet for such a hit comes from the payload rather than the turn. Without that a payload hit renders a snippet with nothing of the query in it and no indication why it came back. The snippet is fts5's own snippet() with column -1, which asks fts5 which of input_json and result_content matched: a command lives in the input and an error message in the result, so picking one of them statically shows the wrong half about as often as the right one. Surfaced on all three read surfaces — `ccvault search` prints "Matched in <tool> payload", the TUI prefixes the snippet with the tool name, and MCP adds matched_tool_name (null for a conversational hit, so an agent can test it rather than infer). One thing found while testing: `tool:` filters by session, not by turn — it joins tool_uses on session_id, so it asks "did this session use the tool". That predates this change and is left alone, but the reference now says so instead of leaving a reader to assume turn scope. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…ve takes
Three integration tests against the built binary:
* TestUpgrade_BackfillsPayloadsWithoutReparsingAnything syncs, strips the
payload columns back off to recreate a pre-009 archive, and re-syncs.
The session file never changes, so the second sync reports 0 indexed
and writes no turns and no tool_uses rows — meaning everything in a
payload column afterwards came from the migration reading raw_json.
* TestSync_WritesPayloadsOnAFreshArchive pins the live path against the
same transcript, because the backfill and the parser are the same
policy implemented twice and have to agree.
* TestSync_ReSyncLeavesNoOrphanedFTSEntries touches the file so sync
re-parses it, then compares tool_uses_fts_docsize against tool_uses.
That shadow table is the only place an orphan is visible: #42
established COUNT(*) on an external-content FTS table resolves through
the base table, and integrity-check with no argument does too.
The rehearsal was also run with a genuinely pre-change binary built from
main, which is the part a Go test cannot do — this binary ships the
migration, so merely opening the archive applies it and the pre-upgrade
state is unobservable. The old binary answers "No results found." for both
needles; the new one finds both and labels them "Matched in Bash payload";
turns.content is byte-identical across the upgrade.
Picking the fixture's tokens corrected a wrong assumption worth recording.
turns.content was never empty of tool material: a call renders as
"[Tool: Bash] $ <command>" cut at 100 characters and a string-valued
result as "[Tool Result: <text>]" cut at 200, so short commands and short
string results have always been findable in summary form. The first draft
of this test asserted a short command was unfindable and failed, correctly.
The two needles it uses now sit where turns.content genuinely cannot reach:
past the 100-character cut, and inside an array-valued tool_result — the
shape half the archive's results use, which fails the content unmarshal
outright and leaves the turn with no content at all.

Measured on a copy of the author's 965,061-turn archive against the same binary minus this change: "git commit" 0.56s -> 1.67s, "deploy" 0.38s -> 0.87s, a query matching nothing unchanged at 0.03s, and "the" — which matches almost every turn — 17.0s before and 15.5s after, because that query's cost is the sort rather than the match. A UNION has to materialise both hit sets where the single-index form could stream one. Recording it rather than discovering it later. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The no-text query branch wrapped an ORDER BY ... LIMIT query in a subquery with no outer ORDER BY, so a filter-only search (tool:Bash after:thisweek) relied on SQLite preserving a subquery's order, which it does not promise. The ordering is what keeps which rows fall inside LIMIT stable between runs over the same data. The two match-attribution columns are now selected inline as literals instead, so the query keeps its original shape, and a test pins the ordering. jeff's toolResultData declared a Success field nothing reads; these adapters declare only the fields they use. input_json does not always parse as JSON, despite the name inherited from agentsview. codex's custom_tool_call records a plain-text body — that is how apply_patch sends a diff — so the model field and the migration column now say to check json_valid before json_extract.

…t an unmatched id
Two silent-mislabel defects, same category: no error, wrong data, and the
wrong data lands in a full-text index where it becomes a search hit
attributed to the wrong thing.
## Migration 009: the result join was keyed on the provider id alone
migration_009_results grouped by tool_use_id, the blocks table likewise,
and the final UPDATE matched on tool_use_id only. Two sessions carrying
the same provider call id would have the GROUP BY collapse them and write
one session's output onto the other's row — and into the other's FTS
document.
Not reachable on the archive as it stands: no id there appears in more
than one session across all 965,061 turns, checked. But that archive
holds no codex sessions at all, so codex's call_… ids are untested, and
whether they are globally unique or numbered per conversation is the
provider's choice rather than ccvault's — call_1-style numbering would
collide immediately. idx_tool_uses_tool_use_id is deliberately
non-unique, which remains the right call and also means nothing in the
schema would catch it.
session_id now travels through both temp tables, both GROUP BYs, the
LEFT JOIN between them, and the UPDATE predicate. tool_uses already
carries it, so the scope costs nothing, and a tool result is always
recorded in the same transcript as its call, so it cannot lose a
legitimate match.
TestMigration009KeepsResultsWithinTheirSession seeds two sessions whose
calls both carry "call_1". Before the fix it failed exactly as predicted:
sess-beta's row held "alpha-only-output", and beta's own output matched
nothing in the index.
The live path never had this defect — ExtractToolUses only ever sees one
transcript's turns, so it is session-scoped by construction.
## jeff: an unmatched tool_id fell back to order
attachJeffResult took the oldest pending call whenever an id-bearing
result matched nothing, which happens when the request preceded any
assistant turn or the call was already answered. The result then landed
on an unrelated call, storing the wrong output under the wrong tool name.
Split into two rules that cannot fall through into each other:
* a result carrying a tool_id matches on that id alone, and is dropped
if nothing pending has it;
* a result carrying no tool_id falls back to order — which the data
forces, tool_id being empty on 633 of 742 real requests — but only
among calls jeff also left unidentified, since an identified call's
own result is still coming and taking its slot mislabels both.
The second test showed the old code swapping two outputs outright:
search_drive got the calendar's output and calendar got search_drive's.
## Also
The migration's note on the 1,302 rows left without an id claimed a
precise duplicate distribution. Three counts of it disagree — two query
shapes of mine and an independent one that found a longer tail — turning
on whether turns with no parseable tool_use block are folded in. The
directly observed figure stays; the distribution is left to the
data-hygiene issue the duplicates need, since the migration behaves the
same either way.

Do not assign payloads to ambiguous historical rows.
Migration 009 matches each tool_uses row to a parsed block by position and tool_name. For pre-009 rows imported through MergeFrom, that position is not a call identity: the import does not preserve ordering or the incoming ID. If repeated calls use the same tool name, the guard still passes after a permutation, so the migration can persist another call's tool_use_id and input_json.
The migration cannot recover the original identity from these rows. Leave matches unverifiable when the historical order is not established, rather than assigning potentially incorrect payloads. Ordering future imports does not repair rows already present when migration 009 runs; those rows require a full re-sync when source files remain available.

Backfill payloads after importing a pre-009 archive.
When the destination already has migration 009, db.Open runs the migration before MergeFrom. A pre-009 archive lacks the payload columns, so sharedColumns excludes them. MergeFrom inserts the older columns and returns without running the turns.raw_json backfill.
The imported tool_uses rows therefore keep NULL payloads. The FTS insert trigger indexes those NULL values, so searches omit the imported input and result content. Extract the migration backfill into a reusable operation and run it for the merged sessions before the import completes. A later sync --full is only a workaround when the source files still exist.

Extract the payload backfill represented by the migration’s UPDATE of tool_uses
into a reusable operation, then invoke it for the imported sessions in MergeFrom
before the import completes. Ensure it handles pre-009 archives whose payload
columns were excluded by sharedColumns, so imported tool input and result
content is populated and available to FTS without relying on a later full sync.

Closes #28.
ccvault parsed every tool call, took the tool name and a file path, and threw the rest away. Tool inputs were never stored. Tool results were recognised only to set a
has_errorflag. So you could not search for a command you ran, a diff you made, or an error a tool printed — a large part of what a session archive is for.This stores both, indexes what is worth indexing, and backfills the whole archive from
raw_jsonso nobody re-syncs.Storage impact — measured, not projected
Timed end to end against a copy of the author's archive (965,061 turns, 261,138 tool uses, 5,057 MB). The live archive was never opened except read-only.
tool_uses_ftsWhat the backfill produced:
bulk_readimageoversizeundecodabletool_uses_fts_docsizeends with exactly 261,138 rows — one per row, no orphans, checked the way #42 established is the only way to see one.integrity-check(1)is clean on the new index.The re-measurement contradicted the sample
The spec was written from 2,824 blocks sampled out of
raw_json. Re-measured over the whole corpus, it held on the question that mattered and got the proportions wrong:The sample had the split inverted. The cause is one tool it under-sampled:
mcp__nanoclaw__ssh_localhostalone is 130,534 results and 360 MB — 91% of all non-bulk result bytes. It is shell output, so indexing it is exactly right, but it means the "everything else" class is the big one, not the small one. The sample's "results max 512 KB" also turns out to have been an image misfiled as a text result.The 128 KB backstop is confirmed, for a stronger reason than the spec gave. Not one of the 211,892 non-bulk results exceeds even 64 KB. The backstop fires on nothing that exists; it is there purely for an unclassified future tool. Kept as specified.
Search behaviour change
A text query now matches
tool_uses_ftsas well asturns_fts. Results carrymatched_tool_nameand, for a payload hit, a snippet drawn from the payload via fts5'ssnippet(…, -1, …)— column-1asks fts5 which of input and result matched, because a command lives in the input and an error message in the result.Newly findable.
turns.contentwas never empty of tool material, which is worth being precise about: a call has always rendered as[Tool: Bash] $ <command>cut at 100 characters, and a string-valued result as[Tool Result: <text>]cut at 200. So short commands and short string results were already searchable, in lossy summary form. What was not reachable at all:models.UserContentBlocktypesContentas astring, so an array fails the whole content unmarshal and the turn stores no content at all. All 130,534ssh_localhostresults are in this class.formatToolUsedoes not special-case, which for most MCP tools is all of them.Still not findable, by design: the body of a
Read/NotebookReadresult and any image payload. Those rows stay findable through their input andfile_path;result_lengthandresult_omitted_reasonsay on the row that the content was left out.Cost. Measured old binary vs new on the full-scale copy:
"git commit"0.56s → 1.67s,"deploy"0.38s → 0.87s, a no-match query unchanged at 0.03s."the"— which matches nearly every turn — was 17.0s before and 15.5s after; that query's cost is the sort, not the match. A UNION has to materialise both hit sets where the single-index form could stream one. Searching two indexes for roughly twice the time of searching one, staying inside a second for a realistic query.Schema
Six columns on
tool_uses— payloads on the existing row, not a new table: the relationship is 1:1 and the row already carriesturn_id/session_id.result_lengthcarries two facts, which is why there is nohas_resultcolumn: NULL means nothing ever answered the call; 0 means it answered with nothing. A second column would say the same thing twice and could disagree with itself.idx_tool_uses_tool_use_idis deliberately not unique. The id is stored verbatim so the #31 follow-up can join it against thetoolUseIdin a subagent'smeta.json; a unique index would be a hazard, not a guarantee — one transcript ingested under two sources legitimately repeats a provider id, and #29 foundINSERT OR REPLACEresolves a unique conflict by silently deleting the conflicting row.FTS cost control (lesson from #29/#8): the FTS table and its triggers are created after the backfill
UPDATEs and populated with onerebuild, so the full-table update pays no per-row index work. Triggers are scoped to exactlyinput_json, result_content— the two indexed columns.How the five adapters express
tool_use_idChecked against real on-disk data, not inferred from the adapter code:
content[].idtoolu_…inputtool_result.contentbytool_use_idpayload.call_idcall_…arguments(JSON) orinput(text)*_output.outputbycall_iddata.tool_id— empty on 633 of 742paramsoutput_previewJeff's mostly-empty
tool_idis why it links by order instead: keying on an id would collapse 85% of its calls onto each other. Its files pair requests and results one for one (742 of each), so the oldest unanswered call is sound, and an exacttool_idmatch still wins when jeff recorded one.Codex's
custom_tool_callis now recorded. The adapter skipped that payload kind outright, soapply_patch— codex's edit tool — left no trace in the archive. Wired here rather than filed separately because its_outputhalf is one of the two payload kinds this change has to start reading, and handling one of a symmetric pair is harder to justify than handling both. Noteinput_jsontherefore does not always parse as JSON; documented on the column.Proof the backfill is non-vacuous
Tests seed under the pre-009 schema.

The backfill fills the first and leaves the 1,302 extras NULL, which is correct — two rows sharing a provider id would make the id useless as a join key — but the duplicates are a data-hygiene problem of their own.extractUserContentsilently swallows whole turns. Becausemodels.UserContentBlock.Contentis astring, a turn holding an array-valuedtool_resultfails the entire unmarshal and storescontent = ''— dropping any sibling text block in that turn too. It is also the accident that has been keeping base64 out ofturns_fts. Deliberately not touched: retyping that field would rewriteturns.content, andturns_ftsbehind it, for a third of the archive.
