converge-development

description

Use when the user wants to develop, debug, or improve the converge framework itself — running an example as a test bed, running the self-improvement loop, observing framework behavior, diagnosing framework bugs, and editing source under packages/. Triggers on phrases like "debug converge", "fix the framework", "run the self-improvement loop", "autonomous framework improvement", "why does the runner do X", "improve the journal", "add a feature to the CLI", "use this example to find bugs in converge".

Converge Development — observe-diagnose-fix the framework itself

Purpose

Use a real example playbook as a test bed. Run it. Watch what the framework does internally — not just the stdout event stream, but the target directory, runstate, and per-attempt forensics the runner writes to disk. When the framework misbehaves (crashes, corrupts state, fails to retry, mishandles a provider response), trace the symptom to the package and module responsible, patch packages/** source, rebuild, and re-run the example to verify.

This skill is only for changes to framework source under packages/ or for running framework-improvement playbooks that target packages/. It is the framework-developer counterpart to converge-control (which babysits a user's playbook and treats the framework as a black box).

Two modes

• Interactive: reproduce a named framework bug, patch packages/**, rebuild, verify.
• Autonomous: run self-improvement-loop for bounded framework hardening, then use its artifacts as the evidence trail.

When to invoke

Trigger on user requests like:

• "Debug converge using " / "Use this example to find bugs in the framework"
• "Why does the DAG runner ?" / "Why is the execution ?"
• "Fix the framework — " / "There's a bug in the manifest/mode/dispatcher/CLI"
• "Improve " / "Add a feature to the CLI" / "Refactor a DAG action"
• "Run the self-improvement loop" / "Autonomously improve the framework"
• "Profile / instrument / add logging to "

Do not invoke for:

• Running a user's playbook to completion → converge-control
• Fixing a stuck user playbook (stale outputs, stall, foreign-playbook hijack) → converge-control
• Designing a new playbook or setting up .converge/ from scratch → converge-planning

If the symptom is purely user-shape (the playbook author made a mistake), route to converge-control. If the symptom is framework-shape (the runner mishandles a valid user playbook), continue here.

Autonomous mode: self-improvement-loop

Run bounded framework hardening with:

converge run --playbook=self-improvement-loop --select improve+

Use only these surfaces unless debugging the playbook itself:

• source: .converge/playbooks/self-improvement-loop/README.md, tasks/improve/TASK.md, templates/epoch/TASK.md, scripts/*.mjs;
• evidence: .converge/artifacts/self-improvement-loop/{journal.md,metrics.jsonl,backlog.jsonl,touched-files.jsonl,convergence.md,epochs/<NNN>/}.

Keep epochs maintainer-grade: clean non-artifact start, real observations before selection, one evidence-backed framework change, patch manifest from git diff, mapped regression commands, command-backed verify/result.json, and stop rather than repeat low-value cleanup.

If the loop exposes a clear framework bug, use the interactive dev loop below for the patch and let the playbook verify the epoch.

The dev loop

Eight steps, in order. Stay in this loop until the example passes cleanly or you hit a structural decision that needs the user.

1. Pick a test bed

If the user named a test fixture or example in the trigger phrase, use it. The smallest one that exercises the suspected subsystem is best — see the fixture→subsystem table at the bottom of reference/framework-map.md.

Test fixtures (under tests/) are the primary dev-loop test beds — they're small, fast, and have corresponding vitest runners. Prefer these for most framework debugging:

Subsystem	Fixture
Navigator / convergence	tests/test-simple-run
Compile / discovery / manifest	tests/test-compile-discover
Multi-provider / agentfn routing	tests/test-mixed-model
mode: spawner / dynamic spawn	tests/test-seeding, tests/test-queue-pattern
Gap detection (input/output)	tests/test-gap-blocked-input, tests/test-gap-missing-output
Buggy-check relaxation	tests/test-buggy-check
Loop detection	tests/test-loop-detection
Multi-attempt convergence	tests/test-multi-attempt
Crash-safe resume	tests/test-resume

Full examples (under examples/) are heavier multi-phase projects. Use when debugging end-to-end behavior that doesn't surface in a single fixture.

2. Build current state

cd <repo-root>
pnpm build

Confirm it exits clean. If the build is already broken, that is the first bug — skip to step 5 with the build error as the symptom.

For faster iteration when changes are scoped to one package:

pnpm --filter @openplaybooks/converge-core build && pnpm --filter @openplaybooks/converge build

3. Run the test bed & monitor

From the test fixture or example directory:

cd tests/<fixture-name>
node <repo-root>/packages/cli/dist/index.js playbook validate default
node <repo-root>/packages/cli/dist/index.js run --playbook=default --dry
node <repo-root>/packages/cli/dist/index.js run --playbook=default

If the fixture uses a non-default playbook name, swap default for the actual name.

Common flags for debugging:

Flag	Use
--force	Force-run a task even if completed/cached
--select <expr>	Run only matching tasks (--select '02-something+' = task + descendants)
--dry	Plan only — show what would execute without running
--verbose, -v	Verbose output

Arm a Monitor on the event stream:

tail -f .converge/journal/<playbook>/events.jsonl | grep -E '(NODE_START|NODE_COMPLETE|NODE_FAIL|CHECK_FAIL|ERROR)'

Then — and this is what makes this skill different from converge-control — also read the internal state:

# DAG state after run
cat .converge/journal/<playbook>/runstate.json

# Per-task forensics
ls .converge/journal/<playbook>/tasks/<taskId>/
cat .converge/journal/<playbook>/tasks/<taskId>/FEEDBACK.md
cat .converge/journal/<playbook>/tasks/<taskId>/LEARN.md

4. Classify the symptom

Symptom shape	Class	Action
Example completes cleanly, no anomalies	none	nothing to fix; ask the user what they wanted to investigate
Stale paths, missing inputs from user playbook	user-shape	wrong skill; route to converge-control
DAG runner crashes / unhandled exception during execution	framework	continue to step 5
Runstate corruption (node status flip-flops, fingerprint mismatch cascade)	framework	continue to step 5
mode: spawner apply fails despite valid converge spawn CLI calls (or, for legacy playbooks, a valid spawn.plan.jsonl)	framework	continue to step 5
agentfn provider throws on a valid response	framework	continue to step 5
Node retries without progress (same CHECK_FAIL across attempts)	framework	continue to step 5
Fingerprint caching broken (unchanged node re-executed unnecessarily)	framework	continue to step 5
CLI arg parsing / exit code wrong	framework	continue to step 5

5. Diagnose

Open reference/framework-map.md. Find the subsystem that owns the symptom. Read the source files listed there. Form a hypothesis.

Then check troubleshooting/playbook.md for a matching past entry. If found → apply the recipe.

If the diagnosis is straightforward and confined to one file, proceed. If it crosses package boundaries (e.g. core/navigator ↔ an agentfn provider, or core/journal ↔ cli/commands-clean), STOP and surface the hypothesis to the user before editing. Same escalation pattern as converge-control.

6. Edit + rebuild

Patch packages/**. Then rebuild — the CLI runs from dist/, not source:

# whole monorepo (safe default)
pnpm build

# or single package (faster when the change is scoped)
pnpm --filter @openplaybooks/<package-name> build

7. Verify

Clear target state from the failing run (so you're testing the fix, not a stale runstate):

# Remove runtime state for a clean re-run
rm -rf tests/<fixture>/.converge/journal
rm -rf tests/<fixture>/.converge/inventory
# Also clean output files the fixture may have produced
rm -f tests/<fixture>/*.txt

Or use the CLI for targeted cleanup:

node packages/cli/dist/index.js clean --select '*' --dir=tests/<fixture>

Re-run from step 3. Confirm:

• Original symptom is gone.
• No new symptoms appeared.
• Run reaches exit 0 clean.

Run the existing vitest suite for the subsystem you touched:

# Run tests for the fixture you're using
npx vitest run tests/<fixture-related>.test.ts

# Or run all tests (slower, use for hot-path changes)
npx vitest run tests/

If no vitest runner exists for the fixture, create one (see tests/compile-discover.test.ts for the pattern — compile + run + verify outputs).

If the symptom returns or a new one shows up → loop back to step 5.

8. Record the recipe

Append a new entry to troubleshooting/playbook.md in the format established there: Symptom / Root cause / Fix / Verification / Files touched. Skip if the fix was a one-off typo. The point is to grow institutional memory so the next invocation of this skill recognizes the symptom faster.

Hard rules — STOP and re-route

• Don't edit framework source without first reproducing the bug against an example. No speculative fixes. The reproducible run is also the verification baseline for step 7.
• Don't skip pnpm build between source edit and re-run. The CLI binary runs from packages/cli/dist/index.js, not source. Edits to packages/**/src/*.ts have zero effect until rebuilt.
• Don't clear state mid-debug with converge clean --all. That wipes fingerprints and can mask caching bugs. Use rm -rf .converge/journal/<playbook> .converge/inventory/<playbook> to clear state for a clean re-run.
• Don't bundle unrelated improvements. One bug, one patch (CLAUDE.md §3 — surgical changes). If you notice adjacent dead code or a refactor opportunity, mention it to the user; don't ship it in the diagnostic fix.
• Don't run pnpm test as a gate for every edit. Too slow for the dev loop. But if your fix touches a hot path — core/src/dag/, core/src/manifest/, core/src/journal/ — flag that to the user and suggest they run pnpm test before commit.
• Don't leave console.log debugging in the source. If you added logging to diagnose, remove it before declaring the fix done.
• Apply known recipes; ask before novel ones. If troubleshooting/playbook.md has a matching entry → apply and continue. If it doesn't, and the diagnosis crosses package boundaries → STOP, state hypothesis, wait for approval.
• Use current terminology. Runtime state lives under .converge/journal/<playbook>/; the task inventory (spawned manifests + ledger) lives under .converge/inventory/<playbook>/. Use runstate.json, not checkpoint.json. Use DAG node, not epic. Use fingerprint caching, not resume checkpoint.

Testing

Running tests

# All root-level integration tests
npx vitest run tests/

# Single test file (fast feedback)
npx vitest run tests/playbook-compile.test.ts

# Watch mode (re-run on file changes)
npx vitest tests/playbook-compile.test.ts

# Per-package unit tests
pnpm --filter @openplaybooks/converge-core test
pnpm --filter @openplaybooks/agentfn test

# Full monorepo test suite
pnpm test

Test file anatomy

Root-level tests live in tests/*.test.ts. They follow a pattern:

// 1. Spawn converge CLI with spawnSync
const CLI = resolve(__dirname, "..", "packages/cli/dist/index.js");
const result = spawnSync("node", [CLI, "run", "--dir=<dir>"], {
  cwd: REPO_ROOT, encoding: "utf-8",
  stdio: ["ignore", "pipe", "pipe"],
});

// 2. Verify outputs on disk
expect(existsSync(resolve(PROJECT_DIR, "EXPECTED_OUTPUT.txt"))).toBe(true);

// 3. Verify journal/manifest state
const manifest = JSON.parse(readFileSync(manifestPath, "utf-8"));
expect(manifest.nodes["task-id"]).toBeDefined();

Key conventions:

• Fixtures live under tests/test-<name>/ with full .converge/ structure
• Clean journal before each test (beforeAll), clean outputs after
• Use describe.skip + binary check for tests requiring external CLIs (claude, codex)
• vitest.config.ts has fileParallelism: false — tests run serially, safe to share fixture dirs
• For compile-only tests, use the parameterized pattern from tests/playbook-compile.test.ts
• For DAG structure tests, use the pattern from tests/playbook-dag.test.ts
• For mode/structure tests (no AI needed), use the pattern from tests/task/mode-*.test.ts and tests/task/run-spawner.test.ts

When to add tests

• Always when fixing a bug that manifested in a specific fixture — add a regression test
• Always when adding a new config schema field (ai:, new frontmatter key) — add a compile test
• Optionally when the fix is a comment, error message, or logging change
• Never skip adding a test for a bug that can reproduce deterministically

Hand-off

Situation	Hand off to
User wants to run a user playbook (not develop the framework)	converge-control
User wants bounded autonomous framework improvement	run self-improvement-loop here, then use its artifacts as evidence
User wants to design a new playbook	converge-planning
Bug is in the user's example/playbook (TASK.md typo, missing input, wrong path)	the user — surface it, don't patch the framework around bad user data
Fix touches a hot path and needs full test coverage before merge	the user — flag the path, suggest pnpm test
