From a49623c448c89df5e5ef7018c64b879f30226287 Mon Sep 17 00:00:00 2001 From: Dmitry Kropachev Date: Mon, 26 Oct 2026 00:51:27 -0400 Subject: [PATCH 1/2] Bound provider failure diagnostics after redacting prompt echoes Remove raw and JSON-escaped prompt echoes before classifying and bounding provider errors, including text-capture newline normalization. Preserve real authentication and usage-limit handling and adapter fallback context. Add a serialized request-size check for callers while keeping unrelated native requests accepted. Cover transport capture and error envelopes, and synchronize the plugin release declarations at version 1.1.23. --- .claude-plugin/marketplace.json | 2 +- .claude-plugin/plugin.json | 2 +- .codex-plugin/plugin.json | 2 +- README.md | 2 +- runtime/shared/executors.py | 29 +++++- tests/test_executors.py | 159 ++++++++++++++++++++++++++++++++ 6 files changed, 188 insertions(+), 8 deletions(-) diff --git a/.claude-plugin/marketplace.json b/.claude-plugin/marketplace.json index 586e1a1..ca1c4db 100644 --- a/.claude-plugin/marketplace.json +++ b/.claude-plugin/marketplace.json @@ -8,7 +8,7 @@ "name": "dk-workflows", "source": "./", "description": "dk-workflows", - "version": "1.1.22" + "version": "1.1.23" } ] } diff --git a/.claude-plugin/plugin.json b/.claude-plugin/plugin.json index 6ee3478..007741b 100644 --- a/.claude-plugin/plugin.json +++ b/.claude-plugin/plugin.json @@ -1,6 +1,6 @@ { "name": "dk-workflows", - "version": "1.1.22", + "version": "1.1.23", "description": "Portable repository workflows, configurable reviewers, and guarded drafting.", "author": { "name": "Dmitry Kropachev" diff --git a/.codex-plugin/plugin.json b/.codex-plugin/plugin.json index 6113d33..ad66ff0 100644 --- a/.codex-plugin/plugin.json +++ b/.codex-plugin/plugin.json @@ -1,6 +1,6 @@ { "name": "dk-workflows", - "version": "1.1.22", + "version": "1.1.23", "description": "Portable repository workflows, configurable reviewers, and guarded drafting.", "author": { "name": "Dmitry Kropachev" diff --git a/README.md b/README.md index baaf572..557ddfe 100644 --- a/README.md +++ b/README.md @@ -1,6 +1,6 @@ # dk-workflows -Independent MIT plugin for Claude Code and Codex.

Suggestions alone do not establish agreement. +- `suggest [--source code|description|all]`: optionally discover candidates without recording or publishing them. The default is `code`, which inspects the complete PR patch and can be costly on large PRs. Use `description` for description-only candidates, or `add` to record an already-established choice. Code discovery retains the complete pinned patch, permalink ranges, and existing decisions in private files beside the decision cache and gives the analysis process a compact manifest for bounded reads. Whole-PR discovery requires inspecting the complete patch; unavailable inspection blocks discovery without deleting recorded choices. Code-discovery requests have a conservative serialized-size limit; provider failure messages are bounded. Description candidates come from outside the existing Decisions section. Suggestions alone do not establish agreement. - `add --json '{"text":"...","references":["EXACT_URL"]}'`: record a selected decision locally. Use exact current discussion URLs or an exact cached code/description suggestion. For a choice authorized directly by the user without a URL, pass `--user-instruction 'exact user instruction'` with an empty references array. - `replace --id DECISION_ID --json '{"text":"...","references":["EXACT_URL"]}'`: record an explicit replacement for an active decision; accepts the same evidence and user-instruction options as `add`. Use this when a new agreement supersedes an existing choice. Do not silently replace published text during analysis. - `publish`: publish the recorded choices and staged replacements from the cached snapshot. This is the only publishing command besides `scan --publish`. Run it when the user requests updating the PR description; existing authorization is sufficient. diff --git a/runtime/dk-pr-decisions/scripts/decisions.py b/runtime/dk-pr-decisions/scripts/decisions.py index 3c34e77..2ac4fb0 100644 --- a/runtime/dk-pr-decisions/scripts/decisions.py +++ b/runtime/dk-pr-decisions/scripts/decisions.py @@ -6,7 +6,7 @@ sys.path.insert(0, str(next(p for p in Path(__file__).resolve().parents if (p / 'shared').is_dir()))) import argparse import base64 -from shared.executors import execute, execute_json +from shared.executors import check_prompt_size, execute, execute_json, provider_failure from shared.repository_scope import inside_checkout import hashlib import json @@ -240,7 +240,12 @@ def pr_diff(pr): owner, repo, _, number = parts target = f"{owner}/{repo}" try: - return run(["gh", "pr", "diff", number, "--repo", target]) + diff = run(["gh", "pr", "diff", number, "--repo", target]) + live = gh_json(["pr", "view", number, "--repo", target, "--json", DIFF_SNAPSHOT_FIELDS]) + if any(live.get(key) != pr.get(key) for key in ( + "baseRefOid", "baseRefName", "headRefOid")): + raise RuntimeError("PR base or head changed while fetching the pinned diff") + return diff except RuntimeError as original_error: # gh pr diff can fail for patches above GitHub's 20,000-line API limit. # Never substitute a diff from the current working tree: it may be stale. @@ -832,6 +837,10 @@ def decision_context(state, local_decisions=None): 'local_decisions': local, 'verified': True} +# Conservative discovery-only headroom for native host envelopes and instructions. +MAX_CODE_DISCOVERY_PROMPT_CHARS = 900_000 + + def suggest_from_code(state, path): previous = state.get('code_suggestions', {}) head = state['pr']['headRefOid'] @@ -842,28 +851,64 @@ def suggest_from_code(state, path): diff = pr_diff(pr) head_repo = (pr.get('headRepository') or {}).get('nameWithOwner') or '/'.join(parts[:2]) links = code_links(diff, f"{urlparse(pr['url']).scheme}://{urlparse(pr['url']).hostname}/{head_repo}", head) - payload = {'diff': diff, 'head_sha': head, 'code_permalinks': compact_code_links(links), - 'existing_decisions': state['decisions']} + # Keep complete evidence outside the request, including after a provider failure. + # A unique directory prevents concurrent discoveries from replacing each other's inputs. + evidence_dir = Path(tempfile.mkdtemp(prefix='code-evidence-', dir=Path(path).resolve().parent)) + evidence = {} + for name, content in { + 'diff.patch': diff, + 'code-permalinks.json': json.dumps(compact_code_links(links), ensure_ascii=False), + 'existing-decisions.json': json.dumps(state['decisions'], ensure_ascii=False)}.items(): + artifact = evidence_dir / name + artifact.write_text(content, encoding='utf-8') + evidence[name] = {'path': str(artifact.resolve()), 'characters': len(content), + 'sha256': hashlib.sha256(content.encode('utf-8')).hexdigest()} + manifest = {'pr_url': pr['url'], 'head_sha': head, 'artifacts': evidence} + (evidence_dir / 'manifest.json').write_text(json.dumps(manifest, indent=2), encoding='utf-8') + schema = {'type': 'object', 'additionalProperties': False, 'required': ['decisions'], + 'properties': {'decisions': SCHEMA['properties']['decisions']}} prompt = ('Suggest only material decisions established by the changed code.
