Verification

The gate this pull request declares, run on the box that wrote it: bin/setup then bin/check, before these changes (base) and after them (head); then bin/stop, the teardown the platform runs when every session ends; then bin/setup and bin/stop once more on the same box (reuse), the way every later session meets it.

Proof: proved — every command ran green at head.

Queued from what this pass found, and none of them runs before this merges:

  • Verify the base runs clean
  • Refine CLAUDE.md into a tight project brain
  • Establish a first-class test harness

Merging

This rewrites how agents read your repo, on a repo the platform has not worked before,
so it is yours to merge — not the bot's. Merging it is also what marks the repo
onboarded; until then coding tasks on it are held (issue triage, PR review and
report-only tasks are unaffected).

major · security bunx @​sentry/mcp-server resolves the newest npm release at every agent start and runs it with the developer's environment, so a hijacked publish executes with SENTRY_ACCESS_TOKEN and DEVELOPERZ_API_KEY in scope. Pin the package to an exact version in the args array.

Not changing this: The finding is correct, but .mcp.json is a platform-owned merge gate this pull request cannot edit — any change to it leaves the PR unmergeable by machine. Pinning bunx @​sentry/mcp-server to an exact version belongs in a separate pull request that owns that file. (.env.example now documents SENTRY_ACCESS_TOKEN, SENTRY_HOST and DEVELOPERZ_API_KEY, but the pin itself needs the .mcp.json edit.)

The decline does not hold at be548e5235c0: the finding still stands at .mcp.json:6. At head, .mcp.json:6 still runs "args": ["@​sentry/mcp-server"] with no version pin, so the supply-chain defect the finding describes is unchanged. The reply concedes "The finding is correct" and only defers the pin to a future PR — a deferral, not a decline the code proves true — so the finding stands until the args are pinned.

The repo-side guard already on the branch records exactly this defect with owner and route — tools/test_rx.py:613-626 (PLATFORM_OWNED_FLOATING_SPECS entry for (".mcp.json", "bunx @​sentry/mcp-server"), suggested pin @​sentry/mcp-server@​0.49.0), scanned by the gate at tools/test_rx.py so the record cannot go stale unnoticed.

The defect stays recorded with its owner and its route at tools/test_rx.py:613-627 (route now names the exact spec to write, bunx @​sentry/mcp-server@​0.49.0, three components, because npm's @​1 is a range), and the gate that keeps that record live and routed is tools/test_rx.py:1042.

Not changing this: The pin can only land in .mcp.json itself, a platform-owned merge gate whose bytes this repo's tools refuse to write (the merge proof accepts only the platform's own bytes), so the change belongs in a separate pull request to the platform's setup template — exactly the route recorded at tools/test_rx.py:613-627 (bunx @​sentry/mcp-server@​0.49.0, full three-component, re-check registry.npmjs.org/@​sentry/mcp-server/latest at pin time). The class is already guarded on this branch: tools/test_rx.py:998 fails on any floating package spec in repo-owned files, :1012 keeps the .mcp.json occurrence as a live routed open defect owned by the platform, and both uv run tools/rx.py check (knowledge base clean) and the pinned suite (88 passed) are green at this head.

Not changing this: The pin cannot land in this PR: .mcp.json:6 is a platform-owned merge gate whose bytes the merge proof accepts only as the platform's own, so args: ["@​sentry/mcp-server"] must be pinned to a full three-component version in a separate pull request against the platform's setup template (the open defect, its owner and that route are recorded at tools/test_rx.py:615-629; re-measured today: 0.49.0 is the registry's latest, and bun and npm both read a partial version as a range). What this PR does close is the repo side of the class: the gate now reads every equals-form spelling (--with=, --from=, --package=, -p=) at tools/test_rx.py:717-747 and 774-820, so no file this repo owns can resolve a package at its newest version unnoticed, and the recurring checkup asks for that class at .dz/schedules/devops.md:21.

Not changing this: .mcp.json is owned by the platform's setup template and is write-locked in this lane — the merge proof accepts only the platform's own bytes for it, so the pin cannot land in this PR and belongs in a separate pull request against that template (.mcp.json:6 args → ["@​sentry/mcp-server@​0.49.0"], the registry's latest on 2026-11-12). The defect stays live and routed meanwhile: tools/test_rx.py:615 records it with owner and route, tools/test_rx.py:1094 fails the gate on any floating spec in a platform-owned file that is not recorded, and every repo-owned file is clean (tools/test_rx.py:1080).

File fence widened for a findings fix. The fix_pr follow-up for this pull request needed to change file(s) this PR did not touch, to fix what its review thread requires (an existing file the finding names, or a new module it needs) — review thread: PRRT_kwDOT1agKs62R6iF:

  • tools/test_rx.py

Why: Thread PRRT_kwDOT1agKs62R6iF asks for a test asserting each project's ruff and pytest step is present in bin/check. bin/check is in my set, but the repo's only root-level test suite — the one bin/check itself runs and CI exercises — is tools/test_rx.py, outside my set. The guard must live there to run in CI.

The platform granted it under the same area lock a new task takes (no other in-flight task holds these files), after checking the path is not a secret, CI configuration or a human-merge path.

No code change warranted. The fix_pr follow-up for this pull request investigated its feedback and concluded no code change is warranted:

No file changed this round.

Sole finding (PRRT_kwDOT1agKs62R6f5, major · security) targets .mcp.json:6 and is
verified accurate: "args": ["@​sentry/mcp-server"] resolves the newest npm release at
every agent start, with SENTRY_ACCESS_TOKEN and DEVELOPERZ_API_KEY in scope. The fix —
pinning an exact version in the args array — can only land in .mcp.json.

Refusal: .mcp.json is in this run's file set but write-locked by the platform ("the
merge proof accepts our App's change to it only as the platform's own bytes, so any edit
here leaves this pull request unmergeable by machine, and the land refuses it"). Per the
same instruction, the reviewer is told the change belongs in a separate pull request.
Widen_file_set was not called: the file is inside the set (the lock, not set membership,
blocks it), and merge-gate bytes are always refused.

Pattern sweep: grep for bunx/npx invocations across the repo found no other unpinned
package execution — .mcp.json:6 is the only occurrence, so there is no in-scope partial
fix to take elsewhere.

Adds package-pinning guard tests and documents the gate's exact pytest pin in the verify-change skill. One guard defect: the text runner regex misparses flags and omits pnpx/dlx, so pinned commands like npx -y pkg@​1.2 are false-flagged while unpinned pnpm dlx passes.

Include .mcp.json in the scan or narrow…
  • tools/test_rx.py:605 minor · test SCAN_SUFFIXES has no .py, so no Python file is ever read — tools/rx.py already shells out to uv — and a subprocess.run(["uvx", "pkg"]) in any .py file resolves the newest publish with the developer's environment in scope. Add .py to the scanned suffixes.
  • tools/test_rx.py:643 minor · test The text scan's _UNPINNED_RUNNER grabs the first token after the runner as the package, so a correctly pinned npx -y pkg@​1.2.3 or uvx --from pkg==1.0 cmd line is falsely reported, while pnpx/dlx — runners this file's own PACKAGE_RUNNERS names — pass text files unchecked.

No code change warranted. The fix_pr follow-up for this pull request investigated its feedback and concluded no code change is warranted:

Round outcome: no repository file changed. The threads file (tmp/dz/threads.json) is the answer to the one open review thread; this file is the round record.

Why nothing changed
The single open thread (PRRT_kwDOT1agKs62R6f5) asks for the @​sentry/mcp-server spec at .mcp.json:6 to be pinned to an exact version. .mcp.json is a platform-owned merge gate: the merge proof accepts only the platform's own bytes for it, so this pull request may not edit that file — the file is write-locked in this lane. Writing the pin here would leave the pull request unmergeable by machine, so .mcp.json was left byte-for-byte as it is.

The finding itself is correct: bunx spawns the MCP server with the agent's environment, so SENTRY_ACCESS_TOKEN (.mcp.json:8) and DEVELOPERZ_API_KEY (.mcp.json:26) are in scope for whatever npm serves newest.

What the fix needs, and where it lands
In the platform's setup template that generates .mcp.json, one line:

  •  "args": ["@​sentry/mcp-server"],
    
  •  "args": ["@​sentry/mcp-server@​0.49.0"],
    

0.49.0 is what the npm registry's dist-tags.latest names at the time of this round (registry.npmjs.org/@​sentry/mcp-server); the template should pin whichever exact release it has reviewed. That change is a separate pull request against the platform's template, not against this repository — it cannot land on this branch.

Class check across the files this pull request touches
The finding names a class: a package resolved at latest, with the developer's environment in scope. Every file this pull request touches was searched for it. No repo-owned file resolves a package at latest; the only occurrence is .mcp.json:5-6, in the platform-owned file. The repo-side guard is tools/test_rx.py:687 (test_no_repo_owned_file_resolves_a_package_at_latest): it scans every repo-owned text file for npx/bunx/uvx/dlx/pnpm-exec package specs and for unpinned --with, and the four platform-owned files are excluded from it by name (tools/test_rx.py:580-587, .mcp.json at line 585).

Follow-up, only after the template pins the version
Remove ".mcp.json" from PLATFORM_OWNED_FILES (tools/test_rx.py:580-587) so the repository's own guard covers that file too. It cannot happen before the template changes: until then the guard would go red on a file this repository is not allowed to edit.

No code change warranted. The fix_pr follow-up for this pull request investigated its feedback and concluded no code change is warranted:

No file changed this round. One review thread was open, and its fix is refused by the lane.

Thread PRRT_kwDOT1agKs62R6f5 [major, security] on .mcp.json:6 asks to pin bunx @​sentry/mcp-server to an exact version in the args array. The finding is real: .mcp.json line 6 still reads "args": ["@​sentry/mcp-server"], which resolves the newest npm publish at every agent start.

Refusal: .mcp.json is listed in my file set but is write-locked — it is a merge gate whose bytes the platform's setup template owns, and the land refuses any edit to it. The lane contract says to reply that the change belongs in a separate pull request, which is what the threads.json verdict does. widen_file_set was not called: the path is not outside my set, it is a write-locked merge gate (a platform/human-merge path, always refused by widening).

What this branch already carries for the defect: tools/test_rx.py:604-611 records the floating spec (".mcp.json", "bunx @​sentry/mcp-server") in PLATFORM_OWNED_FLOATING_SPECS with its named route ("platform template: pin @​sentry/mcp-server to an exact version — it starts at every agent start with the developer's SENTRY_ACCESS_TOKEN and DEVELOPERZ_API_KEY in scope"), and tools/test_rx.py:757-773 fails the gate if any platform-owned file carries an unrecorded floating spec — so the pattern cannot recur unnoticed. Widening the pattern check: the same gate scans every repo-owned text file (test at tools/test_rx.py:743-754) and finds no unpinned npx/bunx/uvx spec anywhere else.

Checks run, both green:

  • PYTHONIOENCODING=utf-8 uv run tools/rx.py check → "knowledge base clean", exit 0
  • uv run --with 'pytest==9.1.1' pytest tools/test_rx.py -q → 55 passed, exit 0

No code change in this round

Thread PRRT_kwDOT1agKs62R6f5 — .mcp.json:6 — declined (fix not possible in this PR)

The finding asks for an exact-version pin of @​sentry/mcp-server in the args array of
.mcp.json:6. .mcp.json is a merge gate owned by the platform's setup template: the
platform refused this App's write to it, because the merge proof accepts only the
platform's own bytes for that file, so any edit here leaves #17
unmergeable by machine. The pin therefore belongs in the platform's setup template, in a
separate pull request. Nothing else in this branch can stop bunx @​sentry/mcp-server
from resolving the newest publish at every agent start.

What this branch already carries (unchanged this round)

  • tools/test_rx.py:604-611 — PLATFORM_OWNED_FLOATING_SPECS records the floating spec
    bunx @​sentry/mcp-server in .mcp.json with the route that fixes it.
  • tools/test_rx.py:757-773 — the four platform-owned files are scanned and the gate
    fails on any floating package spec that is not on that list, so a new floating spec
    in a platform-owned file is red, not silent.
  • tools/test_rx.py:743-754 — the gate fails on any floating package spec in a
    repo-owned file, which covers every file this pull request touches.

Evidence (repo's own commands, this run)

  • PYTHONIOENCODING=utf-8 uv run tools/rx.py check → knowledge base clean (exit 0)
  • uv run --with 'pytest==9.1.1' pytest tools/test_rx.py -q → 55 passed in 1.77s (exit 0)
  • direct scan through the gate's own helpers:
    • .mcp.json → ['bunx @​sentry/mcp-server'] — platform-owned, recorded defect
    • .dz/maintainer/reviewer.md → ['--with pytest'] — platform-owned, recorded defect
    • .dz/maintainer/maintainer.yml, .github/workflows/ci.yml → none
    • repo-owned files → none

The defect class the finding names — a package resolved at its newest publish with the
developer's environment in scope — has no occurrence left in any file this pull request
touches. The one remaining occurrence is in the platform's own file, which this branch
may not edit.

No injection or secret surface widens; the gate rewrite strengthens runner detection, but the rewritten _EXACT_VERSION accepts npm partial ranges like pkg@​1 as exact pins, so a certified-pinned spec can still resolve the newest matching publish at run time.

Tightens the repo's package-resolution gate: npm partial versions (@​1, @​1.2) are no longer read as pins, with tests for the npm and PEP 440 grammars. Low risk; the only defect is a wrong PEP 440 rationale in a new comment, which leaves the gate's behaviour unchanged.

  • tools/test_rx.py:830 minor · docs PEP 440 does not zero-pad ==: packaging compares the release segment as a tuple, so ==1 matches only a version published as exactly 1 — it does not match 1.0.0 (pip install 'pytest==6.2' fails although 6.2.0 exists). The conclusion (one publish at most) still holds, so fix the wording at…

No code change warranted. The fix_pr follow-up for this pull request investigated its feedback and concluded no code change is warranted:

No file changed this round. One review thread, and its fix is refused.

Thread PRRT_kwDOT1agKs62R6f5 [major] (.mcp.json:6, unpinned bunx @​sentry/mcp-server):

REFUSAL: .mcp.json is one of the four platform-owned merge gates this run is
forbidden to write ("the merge proof accepts our App's change to it only as the
platform's own bytes ... the land refuses it"). The finding's concrete ask —
pin the package in .mcp.json's args — can therefore not land on this branch;
per the lane rule the reply is that the change belongs in a separate pull
request to the platform's setup template. Verdict recorded as "declined" in
tmp/dz/threads.json with that reason. No widen_file_set was requested: the file
is inside my set but platform-owned, so a widening of my set cannot grant its
bytes, and editing it would leave the PR unmergeable.

Why this is the complete answer at this head:

  • The branch already records the defect with owner and route: tools/test_rx.py
    PLATFORM_OWNED_FLOATING_SPECS (:613-627) holds (".mcp.json",
    "bunx @​sentry/mcp-server") owned by "the platform's setup template" with the
    route "pin @​sentry/mcp-server in .mcp.json's args to a FULL three-component
    version — bunx @​sentry/mcp-server@​0.49.0 ... re-check
    registry.npmjs.org/@​sentry/mcp-server/latest". The record is machine-enforced,
    not prose: test_every_recorded_floating_spec_is_live_and_routed (:1042) fails
    when the platform pins it (stale entry) or when the route goes missing.
  • The bug class is guarded repo-wide: test_no_repo_owned_file_resolves_a_package_at_latest
    (:998) fails on any floating package spec in any repo-owned file, across every
    runner spelling (bunx, bun x, npx, pnpx, uvx, pnpm/npm/yarn dlx/exec, uv tool
    run/install), config command/args pairs, and partial npm versions (:946).
    test_platform_owned_files_resolve_no_unrecorded_package_at_latest (:1012)
    scans the platform's own files against the recorded-defect list.
  • Pattern search for other occurrences in files this PR touches: a repo-wide
    grep for every runner spelling finds real floating specs only at .mcp.json:6
    (the anchor, platform-owned). Every other hit is the gate's own detector code
    and test fixtures in tools/test_rx.py. No repo-editable occurrence remains.

Checks run at this head, both green:

  • PYTHONIOENCODING=utf-8 uv run tools/rx.py check -> "knowledge base clean", exit 0
  • uv run --with 'pytest==9.2.0' pytest tools/test_rx.py -q -> "88 passed in 2.62s", exit 0

No code change warranted. The fix_pr follow-up for this pull request investigated its feedback and concluded no code change is warranted:

No repository file changed in this round.

Refused: .mcp.json. It is owned by the platform's setup template, and the merge
proof accepts only the platform's own bytes for it, so any edit here leaves the
pull request unmergeable by machine. The thread's fix therefore cannot land in this
PR: it belongs in a separate pull request against that template. Nothing else in the
repo was changed — the class the thread names is already clean everywhere the repo
owns (proof below), so the only remaining action is the platform's.

What that one platform PR must change — both occurrences of the same class, so it
closes the class instead of leaving a second occurrence for a later round:

  1. .mcp.json:6 — "args": ["@​sentry/mcp-server"] becomes
    "args": ["@​sentry/mcp-server@​0.49.0"].
    0.49.0 was the registry's latest on 2026-11-12
    (registry.npmjs.org/@​sentry/mcp-server/latest → "version":"0.49.0", re-read
    this run). A partial version is not a pin: bun and npm both read @​1 as a range
    and serve the newest match, so the version needs all three components. This is
    the thread's finding — the package starts at every agent start and inherits the
    developer's SENTRY_ACCESS_TOKEN and DEVELOPERZ_API_KEY.
  2. .dz/maintainer/reviewer.md:10 — uv run --with pytest pytest tools/test_rx.py -q
    becomes uv run --with 'pytest==9.2.0' pytest tools/test_rx.py -q, the pin the
    gate itself runs (bin/check:56). Same class: the index resolves it at run
    time. Not flagged in this round; listed so the single platform PR closes the
    class rather than the next review round.

State of the class in this repository, measured this run:

  • uv run tools/rx.py check → knowledge base clean (exit 0)
  • uv run --with 'pytest==9.2.0' pytest tools/test_rx.py -q → 99 passed (exit 0)
    • tools/test_rx.py:1080 — no repo-owned file resolves a package at latest: green
    • tools/test_rx.py:1094 — no platform-owned file carries an unrecorded floating
      spec: green
    • tools/test_rx.py:1113 — the scan reads all four platform-owned files: green
    • tools/test_rx.py:1124 — every recorded platform-owned defect is live and has an
      owner and a route: green
  • The detector (tools/test_rx.py) run over the repository — which contains every
    file this PR touches — reports floating specs in exactly two files, both
    platform-owned and both listed above: .mcp.json and .dz/maintainer/reviewer.md.
    No repo-owned file in this PR resolves a package at run time. The scan skips its
    own source (tools/test_rx.py) and the .codegraph/ cache directory; the one
    touched file inside the latter, .codegraph/.gitignore, is five lines of gitignore
    patterns and names no package.

The open defect is already recorded with its owner and its route at
tools/test_rx.py:605-630, so it cannot rot into an unnoticed one: the gate fails
if the platform fixes it (stale record) or if a new floating spec appears in a
platform-owned file (unrecorded). That record is what made this thread's file
visible at all; the remaining action is the platform's, not this repository's.
