Architecture Review -- PR #813 (
|
The 2026-06-20 upstream sync replaced src/tool/task.ts with stub code that references undefined namespaces (Agent, Session, Permission) and an undefined identifier 'rules'. The file is not imported anywhere; the canonical task tool lives at src/tool/tools/task.ts. This is the same broken-stub pattern previously fixed in a91d373 and 8bb906f. Removing the file unblocks Lint, Type Check, and Format Check.

1. src/tool/task.ts weakens permission inheritance and breaks tsc
// src/tool/task.ts:1
export function inherited(input: {
caller: Agent.Info
session: Session.Info
rules: Permission.Rule[]
mcp?: Record<string, any>
}): Permission.Rule[] {
const prefixes = Object.keys(input.mcp ?? {}).map((k) => k.replace(/[^a-zA-Z0-9_-]/g, "_") + "_")
const isMcp = (p: string) => prefixes.some((prefix) => p.startsWith(prefix))
return rules.filter(
(r: Permission.Rule) =>
r.action === "deny" && (r.permission === "edit" || r.permission === "bash" || isMcp(r.permission)),
)
}Multiple problems, all security-relevant:
-
Type identifiers do not exist in this repo.
Agent.Info,
Session.Info,Permission.Ruleare upstreamopencodenamespace
types; Alexi uses flat-import types (e.g.PermissionRulefrom
src/permission/index.js).npm run typechecknow fails with 6 errors
atsrc/tool/task.ts:2-10— meaningnpm run buildand the CI
test:coverage/buildstages are red. -
Undefined free variable
rules. Line 9 readsrules.filter(...)
instead ofinput.rules.filter(...)— at runtime this would throw
ReferenceError: rules is not defined. The function is currently not
imported anywhere (grepforfrom '../tool/task.js'returns nothing),
so the regression is latent — but the file ships in the package and
cannot be safely imported. -
Semantic regression vs. the existing helper. This file is a
partial duplicate ofsrc/agent/subagent-permissions.ts:23
(deriveSubagentSessionPermission) which already exists and is the
security-fix backport from PR #26597. The existing helper deliberately
keepsexternal_directoryrules in addition to deny rules:// src/agent/subagent-permissions.ts:73 const sessionDeniesAndExternal = input.parentSessionPermission.filter( (rule) => rule.decision === 'deny' || (rule.tools && rule.tools.includes('external_directory')) );
The new
inherited()dropsexternal_directoryallow/deny scoping
entirely. If the new function is ever wired up under the same
semantic role, subagents would lose the workdir boundary and could
write outside the parent session's allowed directories. -
MCP namespace prefix confusion.
prefixes = Object.keys(mcp).map(k => sanitize(k) + '_')followed byp.startsWith(prefix)is unanchored. A malicious MCP server name whose sanitized form is a strict prefix of an unrelated permission key would be treated as MCP-scoped, and the filterr.action === "deny" && (... || isMcp(r.permission))only keeps deny rules, so allow-list entries silently drop. Combined, this is a permission denylist-only flip with weak namespace boundaries.
Recommendation: revert src/tool/task.ts from this PR. If upstream
opencode actually intends to introduce a new inherited() helper, port
it as a follow-up that (a) imports PermissionRule from
../permission/index.js, (b) preserves external_directory rules,
(c) anchors MCP prefix matching, (d) ships with tests in
tests/permission*.test.ts per AGENTS.md, and (e) does not duplicate
deriveSubagentSessionPermission.
2. CI quality gates broken on master after merge
Verified locally:
$ npm run build
src/tool/task.ts(2,11): error TS2503: Cannot find namespace 'Agent'.
src/tool/task.ts(3,12): error TS2503: Cannot find namespace 'Session'.
src/tool/task.ts(4,10): error TS2503: Cannot find namespace 'Permission'.
src/tool/task.ts(6,5): error TS2503: Cannot find namespace 'Permission'.
src/tool/task.ts(9,10): error TS2304: Cannot find name 'rules'.
src/tool/task.ts(10,9): error TS2503: Cannot find namespace 'Permission'.
A red master blocks every other agent in the factory — auto-implement,
agent4-review, daily-merge-prs — because they all run the same gate
sequence. Per AGENTS.md "Quality gates": typecheck must be strict and
not silenced. Block the merge until this compiles cleanly.
High (warn)
src/core/package.json introduces a dual-package boundary
{
"$schema": "https://json.schemastore.org/package.json",
"version": "7.3.50",
"name": "@alexi/core",
"type": "module",
"license": "MIT"
}The single-package contract from AGENTS.md ("Single-package npm project,
no monorepo. Root package.json is the only one.") is violated. With
moduleResolution: NodeNext, Node now treats src/core/ as its own
package boundary called @alexi/core. There are 46 import sites
across the repo using '../core/*.js' / '../../core/*.js' (see e.g.
src/cli/interactive.ts:11, src/server/index.ts:13,
src/git/commitMessage.ts:6).
Today this still resolves because every import is a relative specifier,
but:
- Adding
exports/main/typeslater — which is the next obvious
upstream change — will silently shadow some of those relative imports. - Tooling that walks
package.jsonancestors (vitest's resolver,
ts-node, bundlers) may now treatsrc/core/**as ESM-only with a
different scope than the root, including for type resolution in
consumer packages. - The
"version": "7.3.50"is unrelated to the root1.17.13— if this
ever leaks into a published artefact it confuses downstream consumers.
Recommendation: delete src/core/package.json from this PR. Alexi
is intentionally not a workspace; if upstream wants per-directory
metadata, do it via an ADR (role-architecture) and a coordinated
package layout, not via an upstream-sync drop.
Info
npm audit --omit=dev baseline (unchanged by this PR)
package-lock.json is not modified by this PR, so the following are
pre-existing baseline findings, not regressions. Recording them so they
do not get lost:
| Severity | Package | Path | Notes |
|---|---|---|---|
| high | @hono/node-server@1.19.9 |
via @modelcontextprotocol/sdk |
Auth bypass via encoded slashes / repeated slashes in serveStatic. |
| high | axios@1.15.1 |
via @sap-ai-sdk/ai-api |
Multiple: prototype pollution gadgets, NO_PROXY IPv4-mapped-IPv6 bypass, ReDoS, Proxy-Authorization leak on redirect. Material risk: the SAP AI Core path uses axios with proxy creds. |
| high | xlsx@0.18.5 |
direct prod dep | Prototype pollution + ReDoS; SheetJS no longer ships fixes via npm. Consider migrating to their CDN build or removing the dep if the data-export feature does not need it. |
| high | path-to-regexp@8.3.0 |
via express (MCP SDK) |
ReDoS via sequential optional groups / multiple wildcards. |
| high | fast-uri@3.1.0 |
via ajv (MCP SDK) |
Path traversal via percent-encoded dots; host confusion. |
| high | express-rate-limit@8.2.1 |
via MCP SDK | IPv4-mapped-IPv6 bypass on dual-stack. |
| high | form-data@4.0.5 |
via axios | CRLF injection via unescaped multipart field names. |
| moderate | @xmldom/xmldom@0.8.12 |
via mammoth, terminal-image |
XML injection / DoS — only triggered when parsing untrusted XML; mammoth is invoked on user-supplied DOCX. |
| moderate | gray-matter@4.0.3 → js-yaml@3.14.2 |
direct prod dep | Quadratic DoS in YAML merge keys. |
| moderate | qs@6.15.0 |
via express | Remote DoS in qs.stringify. |
| moderate | ip-address@10.0.1 |
via express-rate-limit |
XSS in HTML-emitting methods (we don't render HTML, low practical risk). |
Scope: 12 findings. None block this PR. They should be tracked in a
separate security issue and remediated by bumping
@modelcontextprotocol/sdk, @sap-ai-sdk/*, and reconsidering the
direct xlsx dependency. Do not run npm audit fix --force —
AGENTS.md explicitly forbids it because of the lockfile-drift risk.
Secret leakage in diff
git diff origin/master...HEAD scanned for AICORE_SERVICE_KEY,
clientsecret, BEGIN PRIVATE KEY, xoxb-, ghp_,
sk-[A-Za-z0-9]{20,}, password\s*[:=], base64 blobs >= 200 chars.
No matches. The token substrings in the diff are LLM token-count
metadata and an upstream commit message ("vercel bypass token (#11460)")
quoted inside .github/reports/diff-report-2026-06-20.md — informational
only, not a leaked credential.
Recommendations
- Block-merge until
src/tool/task.tsis removed from this PR, or
replaced with a compiling, tested implementation that defers to
deriveSubagentSessionPermissioninsrc/agent/subagent-permissions.ts. - Block-merge until
src/core/package.jsonis removed (no monorepo
boundary planted via sync). If a real package split is desired,
raise it as an ADR withrole-architecture. - After (1) + (2), rerun the gate sequence locally:
npm run lint && npm run typecheck && npm run format:check && npm run test:coverage && npm run build. - Open a separate
security-labelled tracking issue for the 12
pre-existingnpm audit --omit=devfindings, prioritised by
axioschain (proxy credential leak) andxlsx(no upstream fix
path). - Keep the upstream-sync robot from auto-creating files that reference
undeclared namespaces — add a post-synctsc --noEmitgate inside
sync-upstream.ymlbefore it opens the PR.

1. New nested src/core/package.json ships a different package identity
File: src/core/package.json:1-7
Severity: warn
{
"$schema": "https://json.schemastore.org/package.json",
"version": "7.3.50",
"name": "@alexi/core",
"type": "module",
"license": "MIT"
}This is an upstream artifact from packages/core/package.json in the source repo (sst/opencode style) but Alexi is explicitly a single-package npm project, no monorepo (per AGENTS.md). The file:
- Declares a different package name (
@alexi/core) and a wildly different version (7.3.50) than the root (alexi@1.17.13). - Ships in the published npm tarball:
npm pack --dry-runconfirms148B src/core/package.jsonlands inside thealexitarball (the rootpackage.jsonhas nofileswhitelist andprivateis unset, so the entiresrc/tree is published). - Creates a
module: NodeNextsub-package boundary insidesrc/core/. Node's ESM resolver walks up to the nearestpackage.jsonto determine module type and thenamefield, so consumers of the published tarball (or anyone running tooling that walkssrc/) will see two competing package identities in one tree. - Is not imported, referenced, or required by any compiled code path —
tscdoes not copy it todist/(build verified clean), anddist/core/package.jsondoes not exist.
Why this is a security finding rather than just a bug: nested package.json files with mismatched names inside a published tarball are exactly the shape a supply-chain attacker uses to confuse package-pinning and provenance tooling (e.g. SLSA attestations, npm --pack-destination consumers, IDE workspace resolvers). Even when benign, it weakens the trust boundary because reviewers cannot tell at a glance whether @alexi/core is a real sub-package, a typo-squat seed, or a sync mistake.
Recommended fix: remove src/core/package.json in a follow-up chore(core) commit. The canonical Alexi structure has no sub-packages. Track via the same orphan-stub-cleanup pattern documented in docs/CONTRIBUTING.md for src/tool/task.ts. If a sub-package ever is genuinely needed, it must be introduced via an architecture ADR (escalate to role-architecture), not via a sync diff.
Workaround if removal is deferred: add a files whitelist to root package.json (["dist/**", "README.md", "LICENSE"]) so accidental orphans inside src/ cannot be published. This is a defense-in-depth control that this repo currently lacks regardless of this PR.
2. Pre-existing production-dependency vulnerabilities (not introduced by this PR)
Severity: warn (informational for this PR; not blocking merge)
npm audit --omit=dev reports the same 12 advisories on origin/master and on PR HEAD (no delta), so this PR introduces zero new risk. Surfacing them here so the merge does not leave the audit findings invisible:
| Severity | Package | Range | Direct? | Fix |
|---|---|---|---|---|

yes (^0.18.5) |
No fix available — SheetJS prototype-pollution + ReDoS, advisory GHSA-4r6h-8v6p-xvw6 and GHSA-5pgg-2g8v-p4x9. Needs vendor migration or removal. |

| moderate | js-yaml |
<=4.1.1 |
no | via gray-matter@2 (semver-major) |
| moderate | qs, ip-address |

Recommended fix: open a separate chore(deps): audit-fix transitive vulns PR. Do not combine with this sync PR (per role baseline: do not touch unrelated code). For xlsx, escalate to role-architecture for a vendor decision since no fix is available.
Info
- Lockfile untouched.
git diff origin/master...HEAD --stat -- package-lock.jsonis empty, meaning no hand-edits and no transitive surface change. Good. markedpeer-dep risk clear. Resolved version is15.0.12; no>=16upgrade attempted in this PR. Themarked↔marked-terminalABI matrix that has burned us twice is intact.- Orphan
src/tool/task.tsalready neutralised. Commit74f111e5(fix(ci): remove broken sync stub src/tool/task.ts [autohealing]) removed the file before this scan ran. The diff-summary, CHANGELOG entry, anddocs/CONTRIBUTING.mdparagraph still reference it for historical context — that is intentional and correct. - Prompt-injection scan clean. No occurrences of
ignore previous,disregard instructions,system prompt,jailbreak, oroverride rolein the modified.github/prompts/*.mdfiles. Prompts are agent-internal content (not LLM-untrusted input), so this is informational. - Constitution principle I upheld. No new provider-SDK calls outside
src/providers/. No diff undersrc/providers/**.
Recommendations
- Follow-up issue: open
chore(core): remove orphan src/core/package.jsonwith thesecuritylabel. One-line removal; verifynpm pack --dry-runno longer lists it. - Defense-in-depth: add a
fileswhitelist to rootpackage.jsonso accidental sub-trees insrc/cannot reach the npm registry. Currently the published tarball includes 1274 files — far more than thedist/runtime surface needs. - Audit remediation: schedule a separate
chore(deps): audit-fix transitive vulnsPR for the eight high-severity transitive findings; escalatexlsxremoval torole-architecturesince upstream has no fix. - Merge decision for THIS PR: not blocked by security. The diff is dominated by prompt/report regeneration and a benign version bump. The
src/core/package.jsonorphan is awarn, not ablock, because (a) it does not affect runtime, (b) the orphan-removal pattern is already established in this repo, and (c) holding the sync PR for a follow-up cleanup would block daily upstream tracking.

…exi-bot] The 2026-06-20 upstream sync (commit 3ef8b88) emitted an unrelated src/core/package.json with name @alexi/core and version 7.3.50. This repo is a single-package npm project (per AGENTS.md: 'Root package.json is the only one'); no workspaces are configured and nothing imports @alexi/core. The nested package.json also creates a sub-package boundary under NodeNext ESM resolution, which is a footgun. Same orphan-stub pattern as the broken src/tool/task.ts removed in 74f111e. Removing keeps the source tree consistent with the documented single-package architecture.
