Colin McDonnell cb0dbcd371 feat(action): make prepush hook non-blocking after one failure (#777)
* feat(action): make prepush hook non-blocking after one failure

push_branch now treats the repository's prepush hook as best-effort: it
runs at most once per run, surfaces the failure output if the script
exits non-zero, and every subsequent push_branch call this run skips
the hook so the agent isn't blocked by failures unrelated to its
change. The agent can iterate by running the hook command itself via
the shell tool when shell access is available; push_branch will not
re-run the hook automatically after a failure.

Why: a one-line OSS-allowlist change took 9 minutes (#776) because the
agent retried push_branch six times against a prepush hook that was
failing for env-leak and missing-build-artifact reasons unrelated to
the change. CI catches the same checks on the GitHub side; the local
prepush gate was duplicating work and blocking unrelated fixes.

- ToolState: new prepushFailureCount counter (per-run, never resets)
- executeLifecycleHook: returns structured failure (kind/output/exitCode)
  so prepush can compose its own agent-facing message instead of
  inheriting the generic retry/no-retry advice meant for setup
- push_branch: composes a shell-mode-aware error message; surfaces
  prepushSkipped on the success payload + appends a note to the message
- instructions.ts + wiki/prompt.md + docs/comparisons.mdx: updated to
  reflect best-effort semantics

* fix(action): clarify prepush latch semantics + soften static guidance

review fixes from PR #777:

- toolState comment, instructions, success message, tool description:
  replace "runs at most once per run" / "first call only" wording with
  the actual semantic — successful prepush keeps running on later
  push_branch calls; only a hook FAILURE latches the bypass.
- tool description: drop hardcoded "via the shell tool" guidance so
  the static description doesn't mislead in shell:disabled runs (the
  dynamic agent prompt in instructions.ts already does shell-conditional
  messaging).
- LifecycleHookFailure.output JSDoc: match the implementation
  (stderr-preferred fallback to stdout, empty for timeout/spawn).

* fix(action): shorten prepush-skip log to terse operator telemetry

the previous log line tried to address the agent ("re-run the hook
command yourself via shell"), but log.info writes to the action
runtime's stdout — the agent never sees it. agent-facing skip
guidance already lives in the error message from
buildPrepushFailureMessage, the success message when bypassed, and
the system prompt in instructions.ts. log line is now just operator
telemetry.

* refactor(action): drop slop from prepush soft-fail

self-audit pass after the previous review-fix round. removed
duplication between code-level comment and the five other places that
already explain the same behavior, tightened verbose JSDoc, and
collapsed redundant clauses in agent-facing strings.

- LifecycleHookFailure → discriminated union. drops the optional
  exitCode/spawnError fields (and the empty-output sentinel for
  timeout/spawn) plus the corresponding ?? fallbacks in the helper.
- PushBranchTool: 7-line code comment above the latch removed
  (toolState field comment + tool description + error message +
  success message + system prompt all already cover it). tool
  description third sentence dropped (restated the second). success
  message tightened to a parenthetical.
- buildPrepushFailureMessage: 4-line JSDoc → 1 line. shared "if you
  think the failure could indicate a real bug in your code" prefix
  factored out across the shell-conditional branches.
- ToolState.prepushFailureCount comment: 8 lines → 3. the "what" is
  in git.ts; comment now only documents the invariant (never
  decremented within a run).
- instructions.ts prepush guidance: collapsed nested bullets + ternary
  into one paragraph; dropped the "so re-running via shell is the only
  way…" tail that restated "push_branch will NOT re-run it".

* fix(action): hint prepush bypass on dirty tree after hook failure

When push_branch blocks on a dirty working tree and the prepush latch
is already set, tell the agent the hook will be skipped once the tree is clean.

* fix(test): narrow CI matrix for lifecycle and toolState changes

Remove lifecycle.ts from ALWAYS_RUN_ALL and add lifecycle.ts + toolState.ts
to push/git agnostic test coverage so PRs touching prepush latch logic run
targeted tests instead of the full matrix.

Colin McDonnell d857e06731 postrun: tighten unsubmitted-review gate to require create_pull_request_review for Review mode (#724)
The gate at `getUnsubmittedReview` accepted `toolState.finalSummaryWritten`
as a valid Review exit, contradicting the post-failure error message which
already says Review's only valid exit is `create_pull_request_review`.
This let any caller that flipped `finalSummaryWritten` — including a
`task`-dispatched `reviewfrog` subagent calling `pullfrog_report_progress`
in violation of its prose-only read-only contract — silence the gate even
when the orchestrator never submitted a review.

Split per-mode: Review requires `toolState.review`, IncrementalReview keeps
the existing `||` (its post-failure message explicitly accepts
`report_progress` as a "no review warranted" exit). Test split mirrors the
new semantics.

closes #648

Colin McDonnell 8e36f76cfa postrun: thread AgentRunContext through the retry loop instead of repackaging (#652)
* postrun: thread AgentRunContext through the retry loop instead of repackaging

drop the per-gate plumbing in `runPostRunRetryLoop`: the loop now receives
`ctx: AgentRunContext` whole and reads `ctx.stopScript` + `ctx.toolState.*`
directly. `getUnsubmittedReview` becomes a pure utility in postRun.ts
instead of a closure shipped over `AgentRunContext`. `AgentRunContext`
loses 4 fields that duplicated `toolState` (`summaryFilePath`,
`summarySeed`, `learningsFilePath`, `getUnsubmittedReview`) and gains
`toolState: ToolState`. both harness call sites collapse from 11 lines to
7; main.ts deletes the inline closure.

`ToolState` and friends move from `action/mcp/server.ts` to
`action/toolState.ts` so non-MCP code (agents, post-run loop) stops
importing run-state types from the MCP server module.

no behavior change. 503/503 tests green.

* toolState: relocate `CommentableLines` to break dep cycle with mcp/review

`action/toolState.ts` was importing `CommentableLines` from
`mcp/review.ts`, which pulled the entire MCP server compile graph (24
files) into any consumer of `ToolState` — including `cf-worker-indexing`
via the `pullfrog/internal` re-export chain through `utils/log.ts` →
`agents/shared.ts` → `toolState.ts`. that exposed a pre-existing TS
error in `mcp/issueEvents.ts` (octokit types resolve differently under
cf-worker's `moduleResolution: bundler`).

move `CommentableLines` (a small `{ RIGHT: Set<number>; LEFT: Set<number> }`
state-shape type) to `toolState.ts` where it's used; re-export from
`mcp/review.ts` for back-compat with test and call-site imports. cuts
cf-worker's mcp/ compile inclusion from 24 files back to 0.

* postRun: drop mock-heavy retry-loop tests; keep pure gate predicate

`runPostRunRetryLoop` and `executeStopHook` were covered by ~560 lines
of mock-heavy regression-gate tests that stubbed `spawn` / `getGitStatus`
and fabricated `AgentRunContext` to drive orchestration paths. per
AGENTS.md ("prefer no test over a mock-heavy test that only catches the
most obvious form of regression") and the empirical track record — the
one real production failure of this code path (#646) was a missing npm
release, not a logic bug a unit test could catch — the value-to-ceremony
ratio is poor. delete them.

keep only the pure predicate: `getUnsubmittedReview(toolState)` is a
decision function whose four input conditions have user-visible
consequences when wrong. 5 assertions, no mocks, no ctx fabrication.

488 tests still pass.

* toolState: import PrepResult from prep/types.ts, not the barrel

same dep-cycle class as the previous CommentableLines fix. importing
PrepResult from prep/index.ts pulled prep/installNodeDependencies.ts
into the Next.js production build's typecheck graph (via
pullfrog/internal → utils/log.ts → agents/shared.ts → toolState.ts →
prep/index.ts → installNodeDependencies.ts), and Next.js's stricter
NODE_ENV-required ProcessEnv shape rejected an existing
`env: { PATH: ... }` literal.

prep/types.ts is a leaf module with zero imports — re-routing the type
import severs the chain. Vercel preview deploy goes from Error → Ready;
preview-sync stops racing the deploy.

Colin McDonnell 85d25a6fe6 post-run gate: fail review-mode runs that don't submit a review or progress (#638)
* post-run gate: fail the run when review mode finishes without a review or progress

review-mode runs that ended in a text-only assistant turn ("now I have enough
to draft the review...") were silently swallowed: the progress comment was
deleted by stranded-comment cleanup and no review appeared on the PR. user-
visible result was identical to "the agent never ran." caught in
https://github.com/pullfrog/app/actions/runs/25583698781.

new post-run gate alongside stopHook / dirtyTree / summaryStale: derived
inline from toolState (selectedMode in {Review, IncrementalReview} && !review
&& !finalSummaryWritten && hadProgressComment) — no parallel toolState flag.
when it fires, the resume prompt nudges the agent to call either
create_pull_request_review or report_progress; persistent failure after
MAX_POST_RUN_RETRIES surfaces as AgentResult.error.

also: when the post-run loop returns success=false, write the error to the
progress comment before the stranded-comment cleanup runs, and skip the
delete in that case. previously a !success run from the loop would lose the
error message into the void.

IncrementalReview's trivial-skip branch now calls report_progress with a
brief "no review warranted" note instead of exiting silently — keeps the
contract symmetric with the gate and gives the user a visible signal even
on no-op review runs.

documents the literal-record design rule on the ToolState interface so
future fields don't drift back into derived/absence-encoding state.

* review feedback: mode-aware nudge, gate-error preservation, prompt order

addresses three findings from the auto-review on this PR:

1. Review mode nudge no longer offers `report_progress` as an exit. Review
   mode's contract (modes.ts step 5) forbids it; the gate previously sent
   contradictory copy. IncrementalReview's nudge still offers both since
   its trivial-skip path legitimately allows `report_progress`.

2. `writeJobSummary` is now wrapped in try/catch on the success-path
   cleanup. without this, a throw there jumped to the outer catch and
   overwrote the gate's failure message in the progress comment with the
   (less actionable) writeJobSummary error — restoring exactly the
   invisible-failure UX this PR fixes. step-summary writes are
   informational; let them fail silently.

3. `buildPostRunPrompt` reorders gates to match the terminal hard-fail
   order: `stopHook` → `unsubmittedReview` → `dirtyTree` → `summaryStale`.
   when both hard-fail gates co-fire (rare in review modes), the prompt's
   emphasis now matches the user-visible failure message.

new test asserts the IncrementalReview nudge offers both exits while the
Review nudge offers only `create_pull_request_review`. e2e validation
already passed against pullfrog/preview-638-review-stop-hook PR #1
(gate fired once; agent recovered on second turn).

* mode-aware terminal error copy

second auto-review caught a residual contradiction: the terminal hard-fail
error string reported "create_pull_request_review or report_progress" for
both modes, even though the new mode-aware nudge tells Review-mode agents
"Review mode does not have a no-submit exit". the error message now mirrors
the nudge — Review names only `create_pull_request_review`,
IncrementalReview lists both. additional Review-mode hard-fail test asserts
the absence of `report_progress` in the error.

Colin McDonnell d6de1c369a learnings: edit-in-place tmpfile (drop update_learnings tool) (#635)
* learnings: edit-in-place tmpfile (drop update_learnings tool)

learnings now follow the PR-summary file pattern: server seeds
`pullfrog-learnings.md` from `Repo.learnings` at startup, agent reads
it as part of context, may edit in place during the post-run reflection
turn, server reads back at end-of-run and PATCHes if changed.

motivation: `update_learnings` required the agent to pass the FULL
merged list as a string parameter — an output-token tax that grew
linearly with the learnings size, and a constant prompt-context
expansion since the contents were also inlined into the LEARNINGS
section. for repos with mature learnings the prompt was getting
visibly noisy in CI logs.

key changes:
- new `action/utils/learnings.ts` (seed/read helpers + 10k cap)
- `main.ts`: always seed; `persistLearnings` mirrors `persistSummary`
  (success path, error path, exit-signal handler, idempotent guard,
  byte-trim equality skip); forwards `model` for `LearningsRevision.model`
- `LEARNINGS` prompt section now contains only the file path + a
  one-line "read it" instruction (no contents inlined)
- `update_learnings` MCP tool deleted; `action/mcp/learnings.ts` removed
- reflection turn (`buildLearningsReflectionPrompt`) reframed around
  file editing with explicit prune-stale + leave-alone-if-nothing-new
  framing
- `learningsStep` removed from every mode checklist — surface lives only
  in the LEARNINGS prompt section + the reflection turn now

* learnings: harden seed step + refresh stale docs (review feedback)

Three findings from PR review, all implemented:

1. wrap learnings seed in best-effort try/catch (action/main.ts) —
   the always-on seed block ran unconditionally and an unwrapped
   `seedLearningsFile` (mkdir + writeFile) failure (ENOSPC, EACCES,
   hostile sandbox) would unwind into the outer main() catch and flip
   an otherwise-successful run to " Pullfrog failed" before the
   agent even started. asymmetric with `persistLearnings`'s own
   best-effort contract. wrap and log on failure; downstream
   consumers (`persistLearnings`, agent harnesses, `resolveInstructions`)
   already handle `learningsFilePath: undefined` cleanly.

2. refresh wiki/main.md — `resolveInstructions` parameter renamed
   from `learnings` to `learningsFilePath` in this PR; the data-flow
   diagram and the resolver dependency table both still showed the
   pre-refactor signature.

3. drop deleted `learnings.ts` from ROADMAP.md + RESEARCH.md
   "missing MCP tool tests" bullets — `action/mcp/learnings.ts` was
   removed in this PR; the bullets are otherwise still accurate.

David Blass c6a757424c Stop hook + learnings reflection via post-run loop (#515) (#548)
* add stop hook + learnings reflection to post-run loop (#515)

stop hook (#515): repo-configured script that runs after the agent
finishes. non-zero exit resumes the agent with the hook output as
guidance; persistent failure (3 attempts) marks the run failed. the
dirty-tree and stop-hook gates share a single retry loop so a fix +
push happen in one turn.

learnings reflection: per Colin, the learnings step baked into mode
checklists rarely fires — the agent stays focused on the task and the
meta-ask falls through. the post-run loop now delivers a dedicated
one-shot --continue turn asking the agent to call update_learnings if
relevant, nothing else competing for attention. reflection doesn't
consume the gate-retry budget; if it dirties the tree, the next loop
iteration catches it via the dirty-tree gate.

plumbing: Repo.stopScript column + migration, zod schema, run-context
api, AgentSettings UI. RepoSettings.stopScript threads through to
AgentRunContext and into each agent harness.

subprocess-dependent logic lives in action/agents/postRun.ts to keep
action/agents/shared.ts lean — shared.ts is reachable from
pullfrog/internal, and pulling node:child_process through it leaks
into root tsc (which uses bundler resolution, not NodeNext).

* fix: preserve successful run when reflection turn fails

The post-run reflection turn (update_learnings nudge) is a best-effort
one-shot; its failure must not flip a successful run to failed. Prior
code overwrote `result` with the reflection's return value, so a model
API error during reflection caused the whole run to be reported as
failed even though the gated work had already completed cleanly.

Now: save the pre-reflection result, and if reflection returns
`success: false`, log a warning, restore the prior success, and exit
without re-invoking the gates (re-running a freshly-green stop hook
risks a flaky false-positive failure).

Adds action/agents/postRun.test.ts covering the reflection path —
previously uncovered.

* fix: surface both stop-hook stdout and stderr to the agent

The `(stderr || stdout)` heuristic in executeStopHook dropped stdout
entirely whenever stderr had any content. Scripts that emit a benign
warning to stderr and the actionable error to stdout (common for
wrapper scripts) starved the agent of the information it needed to
fix the issue.

Now concatenate both streams (stderr first, stdout second, skipping
empty ones) before truncation. This keeps stdout's tail — usually
where summaries and totals live — intact under the 4096-char cap.

* test: lock in the core post-run retry + reflection invariants

PR #548's test plan ships four manual verification scenarios.
Convert three to vitest coverage, catching regressions on the hottest
code paths:

- persistent stop hook failure exhausts MAX_POST_RUN_RETRIES and
  surfaces as AgentResult.error with both the retry count and the
  verbatim hook output (so the GitHub-comment rendering stays
  actionable).
- every gate retry is fed the hook output as the resume prompt.
- usage aggregates across the initial run plus every retry (billing
  relies on this).
- reflection turn still fires when no stop hook is configured and the
  tree is clean.

Manual item remaining is the full UI round-trip of the settings form,
which is out of scope for unit tests.

* test: cover executeStopHook soft-fail and truncation invariants

Three paths the PR documents but previously had no regression gates:

- timeout (SPAWN_TIMEOUT_CODE) and activity-timeout
  (SPAWN_ACTIVITY_TIMEOUT_CODE) must return null, not a failure. a
  hook that times out is an infra problem; retrying with an agent
  turn risks an infinite loop.
- spawn errors (ENOENT from a typoed binary, etc.) take the same
  soft-fail path for the same reason.
- oversize hook output is truncated to the last 4096 chars with a
  "truncated" marker, keeping the tail (where summaries live) and
  protecting the 65535-char GitHub-comment budget downstream.

Regression targets — a refactor that accidentally surfaces an infra
failure as a gate failure, or blows the comment budget, will now
fail loudly in CI.

* test: cover soft-fail, no-resume, and short-circuit invariants

Three more documented behaviors that previously had no regression
gates:

- dirty-tree-only is a soft-fail: persistent uncommitted changes log
  and warn but DO NOT flip the run to failed. a regression that
  started surfacing this as AgentResult.error would break every run
  that leaves a test fixture untracked.
- canResume=false + stop hook failure still surfaces the hook failure
  as AgentResult.error. the retry budget is zero so "N retry
  attempts" is correctly omitted from the message, but the run still
  reports WHY it failed rather than silently reporting success.
- initial result with success=false short-circuits the loop: no gate
  checks, no reflection, no resume calls. the original agent error
  flows through verbatim for clean triage.

Also reset mockedSpawn in beforeEach so test state doesn't leak
between cases.

* test: lock in the reflection-dirties-tree → dirty-tree-gate path

The PR description claims: "if the reflection turn dirties the tree,
the loop picks that up on the next iteration via the normal
dirty-tree gate." There was no regression gate on this invariant.

Without it, a refactor that moved the reflection out of the retry
loop (e.g., into a one-shot post-loop call) would silently bypass
the commit-before-you-finish contract whenever the agent misbehaves
during reflection — uncommitted changes would ship as part of the
run's "success" state.

The test sequences three getGitStatus returns (clean → dirty → clean)
and asserts two resume calls: REFLECTION first, then UNCOMMITTED
CHANGES with the dirtying file in the prompt.

* fix: preserve pre-reflection task output when reflection succeeds

the reflection turn's reply ("done" or "updated learnings with N bullets")
is a meta-ask, not a task summary. before this fix, result = reflectionResult
clobbered the original task's output on the returned AgentResult, so
downstream consumers (handleAgentResult's fallback path when toolState is
empty, programmatic callers of main()) saw the reflection's trivial reply
instead of the real summary.

spread reflectionResult to inherit fields subsequent gate retries need
(e.g. the new sessionId claude emits per --resume invocation), but keep
the pre-reflection output verbatim.

* fix: fall back to reflection's output when pre-reflection output is empty

the prior fix used `??` which only fell through on null/undefined. runs
that communicate exclusively through MCP tools (e.g. report_progress) and
emit no plain text leave result.output = "", which `??` preserved as-is —
dropping the reflection's reply and leaving handleAgentResult's fallback
path with nothing to show. switch to `||` so empty-string pre-reflection
output yields the reflection's output instead of ""; non-empty task output
still wins as intended.

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* test: drop reflection-failure-skips-hook test (over-specified control flow)

the test pinned the literal `break` in the post-reflection failure
branch with stopScript=null, asserting only that getGitStatus was
called once. that's not a behavior contract — a reasonable refactor
(e.g. `continue` to re-check gates with explicit flake guards) would
fail this test even though the new behavior would be fine. the
"does not flip a successful run to failed" test already covers the
only thing callers depend on.

* test: drop low-value mock-driven tests from postRun

- "fires the reflection turn when no stop hook is configured" — fully
  subsumed by the output-preservation test (asserts task output
  survives, which is only possible if reflection fired).
- "uses stdout alone" / "uses stderr alone" — pin format trivia
  (`filter(Boolean).join`) that LLMs ignore.
- "returns empty output (not undefined) when both streams are empty"
  — guards a TS-impossible case; every consumer uses `output || "(no output)"`.
- "returns null on activity-timeout" — duplicate of the timeout test;
  same `return null` branch with a different constant.
