From 8c999702680f246364500ffdcec07f8f91f223f7 Mon Sep 17 00:00:00 2001 From: Dean Sharon Date: Sat, 11 Apr 2026 15:50:08 +0300 Subject: [PATCH 01/42] =?UTF-8?q?feat(learning):=20phase=20A=20=E2=80=94?= =?UTF-8?q?=20core=20infrastructure=20for=20unified=20self-learning=20+=20?= =?UTF-8?q?project=20knowledge?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the four-component detection pipeline: 1. Channel-based transcript filter (D1, D2): - scripts/hooks/lib/transcript-filter.cjs — testable CJS module - Rejects isMeta, sourceToolUseID/toolUseResult, framework XML wrappers, tool_result arrays, empty turns (<5 chars) - Produces USER_SIGNALS (workflow/procedural) and DIALOG_PAIRS (decision/pitfall) 2. Per-type thresholds + 4-type detection (D3, D4): - THRESHOLDS constant: workflow(req=3,spread=3d), procedural(req=4,spread=5d), decision(req=2,spread=0), pitfall(req=2,spread=0) - calculateConfidence(count, type) — per-type required count - process-observations extended: all 4 types valid, quality_ok stored/honoured, per-type promotion gate requires quality_ok===true - filter-observations updated to include all 4 types 3. Deterministic renderers (D5): - render-ready — dispatches by type: workflow → .claude/commands/self-learning/.md procedural → .claude/skills/self-learning:/SKILL.md decision → .memory/knowledge/decisions.md#ADR-NNN (with lock, capacity=50) pitfall → .memory/knowledge/pitfalls.md#PF-NNN (with lock, dedup, capacity=50) - All writes atomic (tmp+rename), manifest schemaVersion=1 maintained 4. Reconciler + feedback loop (D6, D13): - reconcile-manifest — session-start op, detects deletions (confidence×0.3, status=deprecated) and edits (hash update only, no penalty per D13) - Anchor-based checks for knowledge file entries (ADR/PF missing = deletion) - Stale manifest entries (no matching obs) silently dropped - session-start-memory: reconciler call added before TL;DR injection 5. Additional ops: - merge-observation : in-place dedup/reinforce (D14), FIFO cap 10 (D12), ID collision recovery _b suffix (D11), Levenshtein mismatch flagging - knowledge-append: standalone knowledge file writer - acquireLock()/releaseLock(): shared lock helper extracted from shell patterns 6. New background-learning pipeline: - extract_batch_messages: uses transcript-filter.cjs, produces USER_SIGNALS + DIALOG_PAIRS - build_sonnet_prompt: new 4-type prompt, no artifact sections (D10, D5) - render_ready_observations: calls render-ready after process_observations - check_staleness: grep-based code-ref staleness pass (D16) Unit tests: 9 test files, 80 new tests (100% passing) Known regressions: 2 tests in shell-hooks.test.ts encode old behaviour (confidence formula, quality_ok promotion gate) — Coder 3 will update --- scripts/hooks/background-learning | 344 ++++++---- scripts/hooks/json-helper.cjs | 781 ++++++++++++++++++++++- scripts/hooks/lib/transcript-filter.cjs | 171 +++++ scripts/hooks/session-start-memory | 8 + tests/learning/filter.test.ts | 268 ++++++++ tests/learning/merge-observation.test.ts | 313 +++++++++ tests/learning/reconcile.test.ts | 326 ++++++++++ tests/learning/render-decision.test.ts | 180 ++++++ tests/learning/render-pitfall.test.ts | 137 ++++ tests/learning/render-procedural.test.ts | 128 ++++ tests/learning/render-workflow.test.ts | 133 ++++ tests/learning/staleness.test.ts | 199 ++++++ tests/learning/thresholds.test.ts | 261 ++++++++ 13 files changed, 3096 insertions(+), 153 deletions(-) create mode 100644 scripts/hooks/lib/transcript-filter.cjs create mode 100644 tests/learning/filter.test.ts create mode 100644 tests/learning/merge-observation.test.ts create mode 100644 tests/learning/reconcile.test.ts create mode 100644 tests/learning/render-decision.test.ts create mode 100644 tests/learning/render-pitfall.test.ts create mode 100644 tests/learning/render-procedural.test.ts create mode 100644 tests/learning/render-workflow.test.ts create mode 100644 tests/learning/staleness.test.ts create mode 100644 tests/learning/thresholds.test.ts diff --git a/scripts/hooks/background-learning b/scripts/hooks/background-learning index 446033e..0cb822d 100755 --- a/scripts/hooks/background-learning +++ b/scripts/hooks/background-learning @@ -132,19 +132,28 @@ check_daily_cap() { } # --- Batch Transcript Extraction --- +# DESIGN: D1 — two-channel filter produces USER_SIGNALS and DIALOG_PAIRS. +# D10 — single LLM call per batch processes all channels together. extract_batch_messages() { local encoded_cwd encoded_cwd=$(echo "$CWD" | sed 's|^/||' | tr '/' '-') local projects_dir="$HOME/.claude/projects/-${encoded_cwd}" local batch_file="$CWD/.memory/.learning-batch-ids" + local filter_module="$SCRIPT_DIR/lib/transcript-filter.cjs" if [ ! -f "$batch_file" ]; then log "No batch IDs file found" return 1 fi - USER_MESSAGES="" + if [ ! -f "$filter_module" ]; then + log "transcript-filter.cjs not found at $filter_module" + return 1 + fi + + USER_SIGNALS="" + DIALOG_PAIRS="[]" local session_count=0 while IFS= read -r sid; do @@ -155,48 +164,43 @@ extract_batch_messages() { continue fi - # Single-pass extraction: pipe all user-type lines through one jq/node process - local session_msgs - if [ "$_HAS_JQ" = "true" ]; then - session_msgs=$(grep '"type":"user"' "$transcript" 2>/dev/null \ - | jq -r 'if .message.content then - if (.message.content | type) == "string" then .message.content - else [.message.content[] | select(.type == "text") | .text] | join("\n") - end - else "" end' 2>/dev/null \ - | grep -v '^$' || true) - else - session_msgs=$(grep '"type":"user"' "$transcript" 2>/dev/null \ - | node -e " - const lines = require('fs').readFileSync('/dev/stdin','utf8').trim().split('\n'); - for (const line of lines) { - try { - const d = JSON.parse(line); - const c = d && d.message && d.message.content; - if (typeof c === 'string') { if (c) console.log(c); } - else if (Array.isArray(c)) { - const t = c.filter(x=>x.type==='text').map(x=>x.text).join('\n'); - if (t) console.log(t); - } - } catch {} - } - " 2>/dev/null \ - | grep -v '^$' || true) - fi - - if [ -n "$session_msgs" ]; then - # Per-session cap: 8,000 chars ensures each session contributes proportionally - if [ ${#session_msgs} -gt 8000 ]; then - session_msgs="${session_msgs:0:8000}...

PROCEDURAL — durable \"how to do X in this project\" knowledge +Source: USER_SIGNALS only. +Examples: \"when debugging hook failures, check the lock dir first, then tail the log\"; \"to regenerate the grammar, always run \`make lex\` first\"; \"the way to update classification rules is to edit classification-rules.md, then update the router, then align tests\" +Strong signals: \"when , \" phrasing, \"to , \" phrasing, references to specific project tools/files/commands by name. +Weak signals (reject): single imperative with no explanation, generic advice applicable to any project. +Evidence requirement: 2+ user statements describing the same how-to, OR 1 statement with strong instructional tone referencing project-specific entities. + +## 3. DECISION — architectural or scope commitment with explicit rationale +Source: DIALOG_PAIRS. The prior assistant turn is used only to disambiguate what the user is committing to. +The key signal is INTENT + RATIONALE in a single user statement or adjacent sentences. The user must say BOTH what they want AND why. +Template patterns: \"I want X because Y\"; \"let's go with X — Y\"; \"X is better than Y because Z\"; \"not X, but Y, because Z\" +Strong rationale anchors (must be present in user text for a valid observation): \"because\", \"since\", \"so that\", \"to avoid\", \"the reason\", \"the point is\". +Weak signals (reject): one-word approvals (\"yes\", \"ok\"), preferences without reasoning, restatement of the assistant's recommendation. +Quality gate: before emitting, ask — \"if I delete the 'because ___' clause from the user's words, does the statement still capture a decision worth recording?\" If yes, the rationale is not load-bearing and the observation should be skipped. +Evidence requirement: 1 user statement with the rationale anchor present AND quotable. + +## 4. PITFALL — user correction of something the assistant did or proposed +Source: DIALOG_PAIRS. Both the prior assistant content AND the user correction MUST be cited in the evidence array. +Examples: +- prior: \"I'll add a try/catch around the Result parsing\"; user: \"no — we use Result types precisely to avoid try/catch. Do not wrap.\" +- prior: \"Let me amend the previous commit\"; user: \"don't amend pushed commits. Create a new one.\" +- prior: \"I'll delete the \`.pending-turns.jsonl\` file\"; user: \"stop, that's transient state — the queue may still be processing.\" +Strong signals: explicit negation after an assistant action (\"no\", \"don't\", \"stop\"), question-form redirects, re-emphasis (\"please plan carefully, make sure X\"), counter-instructions. +Weak signals (reject): stylistic preferences, typo corrections, clarifying questions, generic warnings, \"thanks\" responses. +PRIOR CONTEXT REQUIREMENT: You CANNOT emit a pitfall observation without quoting the prior assistant text. If DIALOG_PAIRS does not contain an assistant turn immediately before the user's correction, skip the observation. +Quality gate: the pitfall must be tied to a concrete file, tool, command, or subsystem named in the dialog.

Transcript content is split into two channels by `scripts/hooks/lib/transcript-filter.cjs`: `USER_SIGNALS` (plain user messages, feeds workflow/procedural detection) and `DIALOG_PAIRS` (prior-assistant + user turns, feeds decision/pitfall detection). Detection uses per-type linguistic markers and quality gates stored in each observation as `quality_ok`. Per-type thresholds govern promotion (workflow/procedural: 3 required; decision/pitfall: 2 required), each with independent temporal spread requirements. Observations accumulate in `.memory/learning-log.jsonl`; their lifecycle is `observing → ready → created → deprecated`. When thresholds are met, `json-helper.cjs render-ready` renders deterministically to 4 targets: slash commands (`.claude/commands/self-learning/`), skills (`.claude/skills/{slug}/`), decisions.md ADR entries, and pitfalls.md PF entries.

Severity-scaled colors: dim (50-69), yellow (70-89), red (90-100). Picks highest severity across all per-file entries (D27). Dismissed notifications are re-shown when a new threshold is crossed.

Loaded artifacts are reinforced locally (no LLM) on each session end. Single toggle mechanism: hook presence in `settings.json` IS the enabled state — no `enabled` field in `learning.json`. Toggleable via `devflow learn --enable/--disable/--status` or `devflow init --learn/--no-learn`. Configurable model/throttle/caps/debug via `devflow learn --configure`. Use `devflow learn --reset` to remove all artifacts + log + transient state. Use `devflow learn --purge` to remove invalid observations. Use `devflow learn --review` to inspect observations needing attention. Debug logs stored at `~/.devflow/logs/{project-slug}/`. The `knowledge-persistence` skill is a format specification only; the actual writer is `scripts/hooks/background-learning` via `json-helper.cjs render-ready`. **Claude Code Flags**: Typed registry (`src/cli/utils/flags.ts`) for managing Claude Code feature flags (env vars and top-level settings). Pure functions `applyFlags`/`stripFlags`/`getDefaultFlags` follow the `applyTeamsConfig`/`stripTeamsConfig` pattern. Initial flags: `tool-search`, `lsp`, `clear-context-on-plan` (default ON), `brief`, `disable-1m-context` (default OFF). Manageable via `devflow flags --enable/--disable/--status/--list`. Stored in manifest `features.flags: string[]`. **Two-Mode Init**: `devflow init` offers Recommended (sensible defaults, quick setup) or Advanced (full interactive flow) after plugin selection. `--recommended` / `--advanced` CLI flags for non-interactive use. Recommended applies: ambient ON, memory ON, learn ON, HUD ON, teams OFF, default-ON flags, .claudeignore ON, auto-install safe-delete if trash CLI detected, user-mode security deny list. +**Migrations**: Run-once migrations execute automatically on `devflow init`, tracked at `~/.devflow/migrations.json` (scope-independent; single file regardless of user-scope vs local-scope installs). Registry: append an entry to `MIGRATIONS` in `src/cli/utils/migrations.ts`. Scopes: `global` (runs once per machine, no project context) vs `per-project` (sweeps all discovered Claude-enabled projects in parallel). Failures are non-fatal — migrations retry on next init. **D37 edge case**: a project cloned *after* migrations have run won't be swept (the marker is global, not per-project). Recovery: `rm ~/.devflow/migrations.json` forces a re-sweep on next `devflow init`. + ## Project Structure ``` diff --git a/docs/self-learning.md b/docs/self-learning.md index 3486eb0..ef83d11 100644 --- a/docs/self-learning.md +++ b/docs/self-learning.md @@ -93,9 +93,10 @@ npx devflow-kit learn --configure # Interactive config (model, thr npx devflow-kit learn --clear # Reset all observations npx devflow-kit learn --purge # Remove invalid/corrupted entries npx devflow-kit learn --review # Inspect observations needing attention (stale, capped, low-quality) -npx devflow-kit learn --purge-legacy-knowledge # Remove pre-v2 command-phase-written knowledge entries ``` +Removal of pre-v2 low-signal knowledge entries (ADR-002, PF-001, PF-003, PF-005) and orphan `PROJECT-PATTERNS.md` now runs automatically as a one-time migration on `devflow init` — no CLI flag needed.

Remove dead DEVFLOW_E2E_TEST env var (never read in codebase). Issue 2 (staleness reimplementation): Extract the staleness detection algorithm from background-learning's inline shell loop into scripts/hooks/lib/staleness.cjs — a proper CJS module that is both callable by the shell script and importable by tests. Update background-learning to delegate to it via node. Update staleness.test.ts to import the real implementation instead of a TypeScript reimplementation. Issue 3 (runMigrations seam): Add a runMigrations integration seam test suite in tests/init-logic.test.ts that exercises runMigrations with probe migrations injected via registryOverride, verifying correct devflowDir context, per-project root distribution, and idempotency.

All 3 TS atomic-write call sites (learn.ts, legacy-knowledge-purge.ts, migrations.ts) now import from this single source. - Create src/cli/utils/notifications-shape.ts: consolidated NotificationEntry interface and isNotificationMap guard using the STRONGER definition (validates both top-level map and each entry value). Imported by learn.ts and notifications.ts, eliminating the two incompatible local definitions. - Rebase legacy-knowledge-purge.ts D35 → D39 (D35 was colliding with the per-project concurrency cap decision in migrations.ts). - Extract runGlobalMigration and runPerProjectMigration helpers from the 112-line runMigrations body. Each helper encapsulates one scope's dispatch logic including error handling; runMigrations now orchestrates loading/saving state + dispatches. - Remove direct as Migration<'global'>/'per-project' casts from the original inline dispatch (HIGH #4). Casts are re-introduced only at the new helper-call boundary with explicit comments explaining the generic-narrowing constraint. - MED #7 (init.ts warn/info level): confirmed already correct — no change needed.

Removes the 17-line, 5-branch reporting block from runMigrationsWithFallback in init.ts; init.ts now delegates to the extracted helper. MigrationLogger and reportMigrationResult are exported from migrations.ts; init.ts re-exports MigrationLogger for backward compat. MED #6+#8: Split isRawObservation into two phases. Introduce VALID_OBSERVATION_TYPES constant as the single source of truth for valid type values — drives both the guard (phase 1: required fields + includes check) and the exhaustiveness check in the switch (the const type union constrains ObservationType). Extract isOptBool() helper for the three optional flag checks (phase 2), eliminating the mixed-concern boolean chain. MED #10: Add adversarial-input tests for all four type guards. - isRawObservation: 7 cases via getLearningCounts (invalid type, missing required fields, null/array JSON, non-boolean optional flag, valid minimal entry) - isNotificationMap: 11 cases testing null/undefined/array/number/string/primitive-entry/ null-entry/array-entry/empty-map/valid-entry/multi-entry - isSeverity: 2 behavioral cases via getActiveNotification (unknown + null severity fall back to 'dim') - reportMigrationResult: 8 cases covering all branches (empty, failure with/without project, infos, warnings, newlyApplied, verbose on/off) MED #9: Add TOCTOU test for json-helper.cjs writeExclusive (via exported writeFileAtomic). 4 cases: basic write, overwrite, symlink pre-placed at .tmp path (sentinel unchanged), stale .tmp from prior crash. Mirrors pattern from legacy-knowledge-purge.test.ts:218-244. Tests: 884 total (852 prior + 32 new). Build: clean.

Update both comments to state the actual per-holder values and the reason for the deviation. - learn.ts: collapse the verbose JSDoc over `export type { NotificationFileEntry }` into a one-line comment; the D-SEC1 runtime-guard description belongs in notifications-shape.ts (where the guard actually lives), not at the re-export site. - knowledge-usage-scan.test.ts: remove the dead `run` wrapper function and its `void run` suppression. The function wrapped spawnSync (synchronous) in a Promise that resolved immediately and was never called — the two direct spawnSync calls at resultA/resultB were doing the real work. --- src/cli/commands/learn.ts | 13 ++++--------- src/cli/utils/legacy-knowledge-purge.ts | 4 ++-- tests/learning/knowledge-usage-scan.test.ts | 17 +---------------- 3 files changed, 7 insertions(+), 27 deletions(-) diff --git a/src/cli/commands/learn.ts b/src/cli/commands/learn.ts index 8dd0188..6a647fb 100644 --- a/src/cli/commands/learn.ts +++ b/src/cli/commands/learn.ts @@ -10,12 +10,7 @@ import { cleanSelfLearningArtifacts, AUTO_GENERATED_MARKER } from '../utils/lear import { writeFileAtomicExclusive } from '../utils/fs-atomic.js'; import { type NotificationFileEntry, isNotificationMap } from '../utils/notifications-shape.js'; -/** - * D-SEC1: Runtime guard for `.notifications.json` parse results imported from - * notifications-shape.ts.
