* test: add code-understanding fixtures (fake codegraph CLI, repo builder)
* feat: add code_understanding module with builtin + codegraph providers
Provider abstraction behind code_understand(): builtin uses the regex
ast_extractor plus rg cross-file references (dependency-free fallback);
codegraph shells out to the codegraph CLI with defensive JSON parsing.
Focus-map output is ranked symbols with file:line citations, capped by
max_symbols, and never contains source bodies.
* feat(cli): wire code-understand command and doctor code-understanding checks
New 'obsidian-wiki code-understand --project' subcommand emits the focus
map JSON; doctor --project gains 5 code-understanding capability checks
(builtin, rg, codegraph, codegraph-index, codegraph-fresh). Missing
optional CodeGraph reports warn (exit 0); explicit CODE_UNDERSTANDING_
BACKEND=codegraph with a broken backend fails (exit 1).
* feat(skills): add optional code-understanding focus-map step to wiki-update
Step 3b runs 'obsidian-wiki code-understand --since <last_commit_synced>'
between deciding what to distill and distilling. GUARD-soft-fails like
wiki-ingest Step 1c; mandates file:line citations for architectural
claims and a pruning rule that removes relationships no longer
supported by the codebase. Registers CODE_UNDERSTANDING_BACKEND and
CODE_UNDERSTANDING_CODEGRAPH_BIN in the llm-wiki env reference.
* docs: document CODE_UNDERSTANDING_BACKEND and code-understand command
* docs: add CodeGraph install steps; teach wiki-update to offer install
configuration.md gains a Setup subsection under Code understanding
(npm install -g @colbymchenry/codegraph + verify + CODE_UNDERSTANDING_
CODEGRAPH_BIN fallback). wiki-update Step 3b gains an optional offer:
when codegraph is missing and the user wants the enhanced backend, the
agent may install it (with consent) and re-run the step.
* docs(readme): note code-graph-aware /wiki-update (EN + zh-TW parity)
* docs(readme): clarify zh-TW /wiki-update codegraph note
* fix(codegraph): cap impact queries at 25 seeds on full-project scans
Full scans (no --changed/--since) seed from every tracked file, so an
unbounded impact loop fired one subprocess per symbol — hundreds of
codegraph CLI calls on real repos (observed 120s+ timeout on a 4.3k-node
project). Cap impact at 25 seeds, matching the existing callers/callees
cap (seeds[:5]), keeping full scans bounded while --changed/--since
delta scans stay exhaustive for their small seed sets.
Regression test: test_codegraph_caps_impact_queries_on_full_scan pins the
25-call ceiling (RED: 30 calls -> GREEN: <= 25).
* feat(skills): add standalone code-understand skill
Exposes the code-graph-assisted focus map directly to any coding
agent session, not just as wiki-update Step 3b — so it can be invoked
on demand ("help me understand this codebase", "what breaks if I
change X") independent of a wiki sync.
