query-code

Python import-graph + symbol queries via `scan-query` CLI (on PATH after codemap install).

Module: central [--top N], coupled [--top N], deps <mod>, rdeps <mod>, path <from> <to> Symbol (~70–94% token reduction vs Read): symbol <name> [--with-imports], symbols <mod>, find-symbol <pat> Function call-graph (v3 index): fn-deps <qname>, fn-rdeps <qname>, fn-central [--top N], fn-blast <qname> qname format: mypackage.auth::validate_token

NOT for: repo rebuild (use /codemap:scan-codebase); renaming symbols (use /codemap:rename-refs); non-Python files.

Step 0: Index freshness (once per task — skip if already ran this turn)

# timeout: 5000
_CM_PROJ=$(git rev-parse --show-toplevel 2>/dev/null | xargs basename 2>/dev/null || echo "cm")
python "${CLAUDE_PLUGIN_ROOT:-plugins/codemap}/bin/resolve_index_env.py" \
    --output-prefix "codemap-${_CM_PROJ}" 2>/dev/null
INDEX=$(cat "${TMPDIR:-/tmp}/codemap-${_CM_PROJ}-resolve-index" 2>/dev/null || echo "")
[ -n "$INDEX" ] && { [ -f "$INDEX" ] && STATE="present" || STATE="missing"; } || STATE="unresolved"

Branch on $STATE. Auto-build opt-out via SCAN_NO_AUTOBUILD=1 (set to run queries against index exactly as-is — no refresh, no full build); build wall-time echoed when it runs, keeps build cost separable from query cost.

• present → refresh in place (honors the opt-out, echoes build time):

# timeout: 8000
if [ "${SCAN_NO_AUTOBUILD:-0}" = "1" ]; then
    echo "[codemap] SCAN_NO_AUTOBUILD=1 — using existing index as-is (no refresh)"
else
    _CM_BUILD_T0=$(date +%s)
    "${CLAUDE_PLUGIN_ROOT:-plugins/codemap}/bin/scan-index" --incremental
    echo "[codemap] index built in $(( $(date +%s) - _CM_BUILD_T0 ))s"
fi

• missing → no index to query yet; auto-build is refused when opted out:

# timeout: 5000
if [ "${SCAN_NO_AUTOBUILD:-0}" = "1" ]; then
    echo "! codemap index missing and SCAN_NO_AUTOBUILD=1 — refusing to auto-build."
    echo "  Build it manually first: /codemap:scan-codebase"
    exit 1
fi

If not refused → run scan-index in the foreground (wait until it finishes), then re-read INDEX from tmpfile. (Not the codemap:scan-codebase skill — it is disable-model-invocation:true, user-slash-only; build via the scan-index binary.)

• unresolved → surface error, stop

Step 1: Query

Direction — choose before calling:

• rdeps <mod> — callers: what imports X, blast radius of X
• deps <mod> — forward: what X imports

Common mistake: "modules affected if X changes" = rdeps (callers), not deps.

Missing binary fallback:

SQ=$(python "${CLAUDE_PLUGIN_ROOT:-plugins/codemap}/bin/locate_scan_query.py" 2>/dev/null || echo "scan-query")

scan-query rdeps "mypackage.auth"  # timeout: 5000
scan-query symbol "MyClass.method" --with-imports  # timeout: 5000
scan-query fn-rdeps "mypackage.auth::validate_token"  # timeout: 5000

Goal	Command
callers / blast radius	rdeps <mod> [--exclude-tests]
forward deps	deps <mod>
central modules	central --top 10
import path	path <from> <to>
symbol source	symbol <name> [--with-imports]
all symbols in module	symbols <mod>
symbol search	find-symbol <pattern>
outgoing calls	fn-deps module::function
incoming calls	fn-rdeps module::function [--exclude-tests]
blast radius of current git change set	diff-impact [--base REF]

Quality / coverage / test-graph queries (each needs the index version noted — auto-build upgrades):

Goal	Command	Min index
test files that mock a symbol via patch()	`mock-rdeps <mod::sym \	mod>`
public symbols missing a docstring	undocumented [<mod>] [--all]	v4.4
public symbols with no test callers and no mocks	`uncovered [] [--all] [--sort loc\	name\
stdlib / third-party / internal import groups	import-types <mod>	v4.3
doc xrefs for a symbol / find broken refs	xrefs <qname> · xrefs <mod> --broken	v4.5
public symbols with zero callers anywhere	dead-symbols [--min-loc N]	v4.6
modules with zero external importers	dead-modules	v4.6
what a module spawns as a subprocess	subprocess-deps <mod>	v5.2
what spawns a module as a subprocess	subprocess-rdeps <mod>	v5.2
test files that use a pytest fixture	fixture-rdeps <fixture-name>	v5.3
fixture dependency tree for a test file	fixture-graph <test-file>	v5.3
coverage_pct + covered_by for a symbol / module	`coverage <mod::sym \	mod>`
symbols below a coverage threshold	coverage-gap [<mod>] [--all] [--threshold P]	v5.4

Missing/old index → query needing newer version exits with "requires vN+ index" message; re-run auto-build (Step 0) or /codemap:scan-codebase to upgrade.

Anything not listed here — scan-query --help has full reference.

tool_use_error / skill unavailable: do NOT count as query attempt. Run $SQ <same-args> via Bash directly (timeout: 5000). Apply STOP rule after Bash result.

query_complete: true → STOP ALL TOOL CALLS. List complete and authoritative for THIS query's direction. Write answer immediately. Do NOT call codemap again. Do NOT grep/glob/bash to verify. (query_complete direction-scoped: a deps/symbols query on healthy module can be complete even while another file degraded, but rdeps/central/path complete only when degraded: 0. Legacy exhaustive field mirrors query_complete for one deprecation cycle — prefer query_complete.) (Enforced: guard hook denies import-greps for any module already returned complete this session — re-grep wastes turn, blocked. Trust index; holds for every model tier.)

query_complete: false → result direction-incomplete. Check degraded_files (files failed to parse — may hide edges), untracked_py (new files not yet git add-ed — invisible to staleness diff), stale; verify with grep only for those named gaps.

Truncation check: result count = 20 AND --limit 0 not passed → re-run once with --limit 0 (1 budget slot), then apply STOP rule.

Budget: max 3 calls. Non-exhaustive after 3 → report what found, stop.

find-symbol: Python regex — ^Auth.*Handler$ (anchored) or auth (substring). Escape . for literal dot. Always use --limit 0 when counting/ranking to avoid 20-item truncation.

Symbol staleness: stale: true + empty source → Read(path) fallback. stale: false + empty → [source not available — re-run /codemap:scan-codebase].

Targeted edit (known symbol, file >~300 lines): symbol <mod::name> → take line span → Read(offset=span_start−10, limit=span_len+20) → Edit. Slice Read suffices — Edit needs only slice containing target, not whole file. Spans come from index; file changed since scan → spans may drift (self-heal usually covers it). Edit errors "Found N matches" (old_string not file-wide unique) or no-match (drifted out of slice) → do full Read, then Edit with larger unique old_string.

Step 2: Parse JSON + render

scan-query always emits JSON.

Command	JSON key	Render as
rdeps/deps	imported_by/direct_imports	list modules, one per line
central/coupled	central/coupled array	name — N importers, one per line
path	path array or null	A → B → C; null (with reason: "no-import-path", exit 0) → "No import path found."
symbol	symbols[].source	fenced code block; caption = module + line range
symbols	symbols array	type name (lines start–end), one per line
find-symbol	matches array	module:qualified_name (type), one per line
fn-deps/fn-rdeps	calls/called_by	module::fn (resolution), one per line
fn-central	fn_central	count module::fn, one per line
fn-blast	blast_radius	depth module::fn, sorted by depth then name
diff-impact	changed_modules array	module (risk) — changed symbols, one per line; end with test_impact.pytest_cmd

index.stale: true → scan-query already attempted bounded inline self-heal (scan-index --incremental) before answering; stale remaining true means heal was skipped (change set over cap, or git unavailable). Re-run /codemap:scan-codebase --incremental manually, then retry. index.not_covered non-empty → note scope caveat in response. index.degraded > 0 → caveat some modules unparsable; path results may be incomplete. index.confidence == "exact" → skip verification caveats.
