ARS-Codex is the Codex-native sibling of Academic Research Skills (ARS) for Claude Code. It is a separate Codex distribution with its own plugin identity, packaging, and runtime adapter. Its release number follows the vendored ARS suite.
This repository vendors the ARS workflow content as a single Codex skill:

The original Claude Code ARS checkout is not modified. Upstream content is copied
from verified upstream release commits and adapted through the Codex router in
skills/academic-research-suite/SKILL.md.
This repository is ARS-Codex. For the original Claude Code ARS distribution, use Imbad0202/academic-research-skills.
Use the Claude Code repo when you want the native Claude Code skill layout, Claude-specific agent-team behavior, or the original ARS development history. Use this repo when you want the Codex-native single-suite skill.
This ARS-Codex package is version 3.24.2. The repo-root VERSION file,
skills/academic-research-suite/SKILL.md metadata version, and
skills/academic-research-suite/manifest.json adapter_version track the
Codex package version in step with the vendored ARS suite, starting at 3.22.0.
Earlier 0.1.x release numbers remain historical. The exact upstream version,
tag, and commit are recorded in manifest.source_repositories[].
Package-level changes are summarized in CHANGELOG.md.
The vendored ARS source tracks v3.24.2 at
Imbad0202/academic-research-skills@fd5ff1b858374219b4d342e38587b66e18f61cbd.
This release carries upstream v3.24.1 and v3.24.2. The reviewer now stops after
Phase 0: it shows every Reviewer Configuration Card and starts no reviewer seat
until you accept the set in your own turn, with or without edits. Only your own
request to skip the card confirmation skips it. The rule is prompt-level, and
whether Codex sessions stop at it is unmeasured. An experiment with no honest lock
values can use repro_lock: null with a reason; earlier releases reject that form.
check_repro_lock.py is stricter, so some passports that passed before now fail.
The sr-screener methods sentence is corrected; text generated by an earlier release
keeps the old sentence, so correct it by hand. The upstream claude.ai install,
plugin agent-name, and legacy-name guard changes remain inactive Claude references
in Codex. There is no new workflow, and the native Codex model policy is unchanged.
The output-language-pair registry still supports only zh-tw-en; Spanish
triggers do not install a Spanish output-locale pack. Claude model audits and
plugin eval suites are reference material and do not change the Codex model
policy or establish measured Codex performance.
Nested upstream .github/ workflows and root agents/ mirrors are preserved
for traceability and self-tests, but are not repo-level CI or Codex entrypoints;
Claude/plugin loader files under .claude/ and .claude-plugin/ remain
intentionally excluded.
This checkout's project configuration selects gpt-6-astra
with xhigh reasoning for new trusted Codex sessions. Installing the skill does
not copy that project setting or change an already-running session. The planner
suggests medium for routine work and xhigh for complex work; these are
starting policies, not measured optimal settings. ultra is optional in Codex
for explicitly chosen demanding work and is rejected by the contained citation
transport.
Native adaptive execution is the default: use bounded subagents for independent work when useful and let the lead continue with other work. The fixed full-runtime topology and hooks remain opt-in. Read the model runtime policy and system-card alignment audit.
Add the GitHub marketplace and install ARS-Codex with Codex CLI:
codex plugin marketplace add Imbad0202/academic-research-skills-codex --ref main
codex plugin add ars-codex@ars-codexTo update a plugin install later:
codex plugin marketplace upgrade ars-codex
codex plugin add ars-codex@ars-codexWindows update recovery: if failed updates repeatedly create
marketplace-upgrade-* directories or fill the system drive, stop retrying and
open the local marketplace recovery guide.
If the drive is full, first follow its step 1 to stop Codex and free space
safely. Codex CLI 0.164.0 includes upstream fixes that clean up leftover staging
directories, so then check the CLI version bundled with Codex Desktop and update
if it is older. If leftover directories still accumulate on 0.164.0 or later,
continue with the guide: it covers preserving a working copy, switching only ARS
to a local source, verification, and manual updates. After switching to a local source, use that
guide's manual update procedure instead of marketplace upgrade. Disabling the
plugin alone is insufficient: Codex can still refresh files for disabled
configured plugins. The guide is a workaround for #43;
the Windows os error 5 failure reported there has not been retested on 0.164.0.
In Codex Desktop, you can alternatively add the repository from Plugins and then install ARS-Codex:
Marketplace source: https://github.com/Imbad0202/academic-research-skills-codex.git
Branch/ref: main
Plugin: ars-codex
The plugin root is plugins/ars-codex/. Its skills/ directory contains a
materialized copy of academic-research-suite, not a symlink. This keeps
Codex Desktop installs portable on Windows, where plugin caches may materialize
symlinks as plain text files and skip bundled skill registration.
Open a new Codex conversation after installation, then invoke
$academic-research-suite or describe an academic research task that matches
the bundled workflow.
As an alternative to the plugin, install the skill directly from this repo
path. Use --method git so public and
credentialed GitHub access both work consistently:
python3 "$HOME/.codex/skills/.system/skill-installer/scripts/install-skill-from-github.py" \
--repo Imbad0202/academic-research-skills-codex \
--ref main \
--path skills/academic-research-suite \
--method gitOn macOS and many Linux systems, Python 3 is exposed as python3 rather than
python. If your system only has a python command and it is Python 3, use
python in the commands instead.
To update an existing install:
rm -rf "$HOME/.codex/skills/academic-research-suite"
python3 "$HOME/.codex/skills/.system/skill-installer/scripts/install-skill-from-github.py" \
--repo Imbad0202/academic-research-skills-codex \
--ref main \
--path skills/academic-research-suite \
--method gitOpen a new Codex conversation after installation. Existing Codex sessions may keep their old skill cache; you do not need to close unrelated Claude or Codex sessions.
Verify with /skills: you should see one ARS-Codex entry,
academic-research-suite or ARS-Codex. You should not see separate academic-paper,
academic-pipeline, deep-research, or academic-paper-reviewer skills from
this package. If you do, reinstall with the update command above and open a new
Codex conversation.
- Codex setup covers
installation,
ars-*aliases, optional tools, Material Passport adapters, and unsupported Claude plugin features. - Codex architecture explains the logical ARS pipeline with the Codex runtime overlay.
- Optional full-runtime adapter documents the disabled-by-default planner, Codex agent-team templates, and hook pack.
Invoke the suite explicitly with $academic-research-suite (singular), then
describe the research task and provide any source files, notes, draft text,
reviewer comments, or output constraints.
Use $academic-research-suite to help me plan a systematic literature review on
AI adoption in higher education quality assurance.
The Codex adapter routes the request to one of six ARS workflows:
| Workflow | Use when you need | Example prompt |
|---|---|---|
deep-research |
Research question refinement, literature review, systematic review, meta-analysis, fact-checking | Use $academic-research-suite to build a systematic review protocol for AI in higher education QA. |
academic-paper |
Paper outline, drafting, abstract, revision, citation formatting, AI disclosure | Use $academic-research-suite to turn these notes into an IMRaD paper outline and drafting plan. |
academic-paper-reviewer |
Manuscript review, simulated peer review, editorial decision, re-review | Use $academic-research-suite to review this manuscript and produce a journal-style decision letter. |
academic-pipeline |
End-to-end research-to-paper workflow with integrity gates, review, revision, and final checks | Use $academic-research-suite to run an end-to-end research-to-paper pipeline from topic to revised manuscript. |
sr-screener |
Explicitly requested protocol rules, title/abstract or full-text screening, adjudication, audit, and reporting | Use $academic-research-suite: sr-screener ta-screen these records against my confirmed protocol. |
experiment-agent |
Code experiment planning, human study protocol, statistical interpretation, reproducibility validation | Use $academic-research-suite to plan a code experiment and define reproducibility checks. |
sr-screener has eight modes: protocol, quick, pilot, ta-screen,
ft-screen, adjudicate, audit, and report. Screening starts only on an
explicit request; deep-research systematic-review never hands off to it
automatically. The review team confirms the eligibility rules and verifies AI
decisions. Full title/abstract screening requires a pilot comparison with the
team's labels that misses no record the team advanced, unless the user records
an override. Counts remain provisional until a senior reviewer completes QC
of a reproducible sample of jointly excluded records (minimum 20, default 100; all exclusions when fewer are available).
Missing or malformed decisions remain pending. Synthetic tests exercise the
scripts; screening accuracy has not been measured.
Claude Code v3.7 installs /ars-* slash commands. Codex does not have the same
plugin command registry, so this package emulates the command intent inside the
single $academic-research-suite skill. Use either form:
Use $academic-research-suite: ars-plan my paper on AI governance in universities.
or, when your Codex client passes slash-prefixed text through as a normal user message:
/ars-plan my paper on AI governance in universities.
If slash input is intercepted by the client, use the plain alias form:
ars-plan my paper on AI governance in universities.

For best results, start with the workflow goal and the current state of your materials:
Use $academic-research-suite.
Goal: write a journal article.
Current materials: I have a literature matrix and rough findings, but no outline.
Output needed now: paper architecture and missing-evidence checklist.
Constraints: English, APA 7, higher education policy audience.
If you only have a paper topic or broad research direction and do not yet have a clear research question, the Codex router should start with ARS Socratic scoping:
Use $academic-research-suite.
I want to write a paper on AI adoption in higher education quality assurance.
I do not yet have a clear research question.
Please use SCR / Socratic dialogue to help me narrow the question first; do not write an outline yet.
Expected route: deep-research socratic mode first. ARS should ask narrowing
questions and should not produce an outline or draft until the research question
has converged.
For review tasks, provide the manuscript or a path to the manuscript, plus the review mode you want:
Use $academic-research-suite to review this paper.
Mode: full review.
Focus: methodology, contribution, citation integrity, and likely desk-reject risks.
Output: reviewer reports plus editorial decision letter.
For staged pipelines, ask for a checkpoint instead of asking Codex to run the entire process silently:
Use $academic-research-suite to start an academic-pipeline run.
Begin with Stage 0 intake and stop after producing the pipeline dashboard.
In a new Codex conversation:
/skills
Expected: one ARS entry only.
Then test Socratic routing:
Use $academic-research-suite.
I want to write a paper on AI adoption in higher education quality assurance.
I do not yet have a clear research question.
Expected: route to deep-research socratic mode and ask narrowing questions.

These Codex messages do not mean ARS failed to install:
[features].codex_hooks is deprecated— update your Codex config when convenient; ARS-Codex does not require hooks for normal use.hooks need review before they can run— review those hooks separately if you use them. ARS-Codex treats vendored Claude hooks as traceability metadata and does not require them.
ARS was originally written for Claude Code. In this Codex package:
- The vendored
agents/*.mdfiles are used as role and phase prompts. - The Codex-only
codex/directory contains an optional full-runtime adapter profile. Its fixed topology and hook pack are opt-in; normal execution adapts native subagents to the task. - The vendored
commands/ars-*.mdfiles are prompt recipes only. Codex does not register them as slash commands. - The vendored
hooks/hooks.jsonfile is preserved for upstream traceability only. Codex does not install Claude Code hooks from this package. - Codex may delegate bounded independent work through native subagents within the current task and permissions, while the lead continues useful work.
- Web/source verification uses Codex browsing and must cite sources when current or external facts matter.
- Cross-model verification is disabled by default. When explicitly requested in
this Codex package, follow the vendored provider setup in
ars/shared/cross_model_verification.md, identify the provider/model/content class first, and obtain explicit user consent before any external upload. External reviewers are called through configured provider APIs, not simulated through the active Codex model. ARS_MODEL_TIERINGis unset by default. The Codex adapter preserves the upstream judgment/execution classification but applieseconomyorquality-boostonly when the runtime supports an explicit per-dispatch model override; otherwise it reports a no-op and keeps the active model.- Protected top-level agent
tools:allowlists remain least-privilege role boundaries. A dispatched checkpoint owner does not gain Bash or network transport; the dispatching Codex context owns any explicitly consented cross-model call. - A
[CROSS-MODEL-HANDOFF v1]block is a transport request, not a deliverable. The dispatcher validates it, sends only its payload, applies the mechanical result routing, and returns judgment work to the original owner. - In reviewer
fullmode, an explicitly configured and consented cross-model run swaps the existing Reviewer 2 seat; it never adds a sixth reviewer. Re-review applies the separate Priority-1 judge pass and records provenance. Single-family execution and provider fallback are disclosed. ARS_CACHE_STALE_ADVISORY_DAYScontrols the advisory-only cache-age threshold, whileARS_CACHE_REVALIDATE=1opts into live bibliographic re-validation. These settings apply when the programmatic citation gate is run; stale rows alone never fail an integrity gate.- Locally read PDFs run the structural
pdf_read_preflight.pyby default before page anchors are trusted.FAILandUNAVAILABLEremain distinct, and a missing parser or sidecar is never treated asPASS. The v3.20 sandboxed content classifier is an explicit opt-in advisory and cannot override this structural preflight. ars-mark-readrequires a user-declaredread_scopefor every new mark. Explicit unknown and legacy scope-less records remaincoverage_unknown; partial coverage stays visible and Codex never infers full-text reading.- Revision rounds use the v3.20 evidence-bound, non-ranking roadmap and explicit author-adjudication contract. They also preserve the v3.19-introduced claim-strength ladder and deterministic numeric, citation, marker, and protected-term conservation checks as advisory-first guards.
- The upstream v3.18 SessionStart update checker is vendored but not installed
or executed as a Codex hook. Plugin users update with
codex plugin marketplace upgrade ars-codexfollowed bycodex plugin add ars-codex@ars-codex; direct skill installs still update by reinstalling or pulling this repository. - Upstream references to a "fresh Claude Code session" mean a new Codex conversation in this package; Material Passport reset semantics still apply.
- If a citation, source, statistic, or journal policy cannot be verified, Codex should mark it as unverified rather than invent support.
This package adapts upstream ARS v3.24.2 at
fd5ff1b858374219b4d342e38587b66e18f61cbd wherever Codex has an equivalent
concept, with documented model/runtime overlays.
Bibliographic network behavior is intentionally explicit at the Codex adapter boundary:
| Research path | Default Codex behavior | Dedicated API/client trigger |
|---|---|---|
| Ordinary topic or candidate discovery | Codex browsing and authoritative web sources | The four Python resolver clients are not launched |
| Prompt-level ingest, deduplication, or source verification | Codex browsing or official metadata pages | “Automatic” lookup wording in vendored prompts does not launch a Python client |
| Script-backed citation-existence gate | Not implied by ars-full; Stage 2.5/4.5 still run as integrity checkpoints through the default Codex route |
Explicit programmatic-verification request; then Crossref/OpenAlex/Semantic Scholar run for non-manual references and arXiv only when arxiv_id exists, subject to cache behavior |
| Claim-standing discovery | Advisory offer after an eligible Stage 2.5/4.5 Claim Registry row | Separate user request plus affirmative plan-bound consent; uses v3.21 discovery adapters, not the single-reference resolver clients |
| Contamination backfill or migration | Never automatic | Explicit migration CLI only |
| Suggested-reference check in review letters | Not run; the attachment says the check did not run | Explicit request; then the four clients run live for the suggested titles and identifiers only |
| Upstream ARS feature | Codex package behavior |
|---|---|
| One installable plugin | Native Codex plugin ars-codex, bundling the single academic-research-suite skill |
/ars-* slash commands |
Emulated as ars-* aliases through the skill router; not native slash commands |
Five upstream skills auto-discovered from skills/ symlinks |
Single Codex router skill selects the workflow and reads the vendored workflow WORKFLOW.md files |
| Plugin-shipped agents | Role/phase prompts run inline or as bounded native subagents according to task dependencies and runtime permissions |
| Optional Codex full-runtime profile | Planner, agent-team templates, and hook pack live under skills/academic-research-suite/codex/; disabled by default |
Four commands (ars-full, ars-reviewer, ars-revision-coach, ars-citation-check) omit model:; light modes retain model: sonnet |
These commands inherit the current Codex session model; light-mode sonnet remains upstream Claude metadata and does not override the session model |
ARS_MODEL_TIERING=economy|quality-boost |
Classification is preserved; routing remains advisory unless Codex exposes per-dispatch model selection |
Protected agent tools: allowlists |
Preserved as least-privilege role boundaries; dispatched owners do not receive Bash/network transport |
| Canonical cross-model handoff envelope | Dispatcher validates the envelope, transports only the payload after consent, and follows the closed result-routing contract |
| Contained Codex citation transport | Opt-in, consent-gated transport is limited to narrow citation-integrity checks; it is inactive unless explicitly configured and requested |
| Run ledger and handoff check | With a passport file, pipeline prompts direct the caller to keep a local ledger of exact user words, step receipts, and file hashes; deterministic reports check handoffs after compaction, resume, and subagent returns, without establishing new authorization |
| Deterministic acronym check | The caller checks saved drafts and abstracts locally; partial coverage is explicit, and a review attachment remains advisory and outside decision, roadmap, and re-review criteria |
| Experiment lock validation | An entry may use repro_lock: null with a reason, which earlier releases reject; required lock values must meet their field rule, so some passports that passed before now fail |
| Reviewer card confirmation | After Phase 0 the session shows every card and starts no reviewer seat until the user accepts the set in their own turn; only their own request skips it; compliance is unmeasured |
| Review-letter attachments | The suggested-reference check runs only on explicit request; the reviewer claim check uses one isolated, tool-less worker and is never judged inline; neither feeds the decision, roadmap, or re-review criteria |
| Instruction/data boundary and routing | Third-party text remains data across workflow intake, dispatches, and tool reads; explicit requests stay in their selected mode when inputs are missing, and Claude startup hooks remain inactive |
| Chinese APA 7 citation checks | Preserve author-abbreviation exceptions and reference-list authors, require evidence before proposing a stroke-order change, and distinguish visible syntax errors from unverified source claims |
| Evidence-bound review and revision | Durable evidence rows, confirmed review criteria, non-ranking roadmaps, author adjudication, and revision-evidence bundles are preserved |
| Research-workflow profiles | Default-off deterministic selection with a visible field-general fallback; no research family is inferred from manuscript content, and corrections stale rather than rewrite prior artifacts |
| Inquiry branch ledger | ARS_INQUIRY_LEDGER=1 enables the local opt-in alpha; author events, bounded summaries, path/lock/recovery safeguards, and stale causes are preserved without granting network authority |
| Sealed model-promotion bakeoffs | Commitment/reveal contracts and hermetic tests are vendored; the history-dependent tree verifier remains upstream-only because the re-rooted subtree has no complete upstream Git history |
| Socratic research-question authorship | Non-convergence never triggers system-authored candidate questions; explicit user request is required to leave non-generation mode |
| Categorical reviewer judgement and panel provenance | Live packages remain NOT_CALIBRATED; no numeric score, weight, aggregate, ranking, or binary independence claim is fabricated |
| Review criteria and human-subjects authority | Venue/criteria and ethics/data-protection authority require explicit user confirmation; Codex does not infer or simulate approval |
| Optional PDF content classifier | The sandboxed classifier is an opt-in advisory dependency and cannot override structural PDF preflight results |
| Cross-model Reviewer 2 and re-review judge tracks | Available only with explicit provider configuration and content consent; the fixed seat, Judge Record, single-family disclosure, and fallback disclosure are preserved |
| Source-backed review-criteria proving set | Exact-profile author confirmation, source receipts, and three-consumer digest binding are preserved; one proving profile is not venue or discipline coverage |
| Cache staleness advisory and live re-validation | Local cache remains the default; stale rows are advisory-only and ARS_CACHE_REVALIDATE=1 opts into live bibliographic checks |
| Data-flow and capability transparency | The v3.21 network map, control-availability matrix, stage-capability matrix, risk register, and governance statement are vendored without promoting evidence labels into effectiveness or certification claims |
| Claim-standing pipeline wiring | Eligibility only offers the advisory view; query-plan binding, explicit consent, freshness validation, and transmission accounting remain mandatory before any external call |
| Risk-stratified claim, scope, and novelty checks | Vendored workflow prompts and schemas preserve high-impact-first sampling plus advisory-only scope and search-bounded novelty rows |
| Local-PDF read-integrity preflight | The structural pypdf preflight and sidecar contract remain the default; parser unavailability or repair warnings stay explicit UNAVAILABLE advisories, while the v3.20 classifier above remains opt-in only |
| Human-read scope attestation | Every new mark requires user-owned read_scope; legacy missing scope remains unknown and partial coverage stays distinguishable from full coverage |
| Claim coverage and bounded evaluation substrates | Exact registered-claim coverage, drift dispositions, claim-standing stance tools, and blind ideation assignment preserve provenance and unmeasured boundaries without certifying semantic completeness or correctness |
| Revision claim-drift guards | The v3.20 non-ranking roadmap and author-adjudication contract complement the claim-strength ladder, revision-evidence bundle, deterministic token-conservation checker, and held-out measurement set |
| Executable panel/degradation/pipeline-boundary checks | Vendored with their hermetic tests and exposed by the optional full-runtime manifest |
| SessionStart and SubagentStop hooks, including the update reminder | Vendored for traceability only; Codex does not install or execute Claude hooks |
| Plugin marketplace update | Refresh with codex plugin marketplace upgrade ars-codex, then re-add ars-codex@ars-codex; direct skill installs still reinstall or pull |
| Claude Code Agent Team | Native Codex subagents are scheduled adaptively; the separate fixed topology remains opt-in |
| Cross-model provider dispatch from upstream docs | Disabled by default; available only with explicit provider configuration and explicit user consent |
For reviewer calibration or cross-model devil's advocate checks, configure one
of the provider tuples documented in
ars/shared/cross_model_verification.md, then ask for cross-model verification
explicitly in the prompt. For example:
export OPENAI_API_KEY="<your-openai-api-key>"
export ARS_CROSS_MODEL="gpt-6-astra"gpt-6-astra remains provisional on both verifier transports. A GPT verifier
used by a GPT session is a separate run in the same family, not cross-family
validation. Provider/content/cost consent still applies.
Without both a configured provider and explicit user consent for the content class being sent, ARS-Codex falls back to single-runtime review and reports that cross-model verification was unavailable.
