Then use AI to expand alternatives and challenge assumptions. This is a provisional recommendation for preserving different starting points, not a tested finding that this sequence wins. The available research does not establish that AI must always come last.\n\nJudge two outcomes separately: how promising each proposal is, and how many distinct directions the collection explores. An illustrative example: twelve useful variations on a reminder feature could score well individually while leaving discovery, onboarding and accessibility problems unexplored. Better individual output therefore need not mean a broader search. For your team, the concern is losing alternatives before you know which user problem deserves investment.\n\n[Terwiesch and colleagues’ 2026 paper](https://journals.sagepub.com/doi/10.1177/10591478261474243) studied text proposals for college-student products costing at most $50. GPT-4-0314 ideas generated in May 2023 received higher purchase-intent ratings than historical MBA-student ideas; their pools were less diverse. Study 3b instead used August 2024 GPT-4o. Table 3 measures diversity as one minus average pairwise cosine similarity of text embeddings: human ideas scored 0.773, human-picked problems with AI solutions 0.739, and baseline GPT-4o 0.679. These are semantic-distance scores, not quality or success rates. That workflow reused student ideas; participants did not interact with AI. The paper supports investigating varied problem inputs, but neither its text-only college-market setting nor purchase intent establishes results for professional design teams.\n\n[Jo and Raghavan’s April 2026 preprint, version 1](https://arxiv.org/html/2604.03529v1), randomized 200 Prolific participants across AI access and incentives for originality or technical quality. They wrote 250–350-word stories using GPT5-Mini where assigned; the accessed text names the model but gives no dated snapshot or experiment dates. Originality incentives increased diversity among AI-assisted outputs, although they remained more similar than human-only stories on most embedding measures. Crucially, everyone brainstormed without AI first. This tests incentives within that sequence, not whether the sequence beats AI-first work. It is a single-session writing study, with diversity rather than the quality–diversity trade-off as its primary focus.\n\nTogether, these findings make workflow and evaluation criteria relevant, while leaving ordering unresolved. The defensible decision is to protect room for independent problem framing and inspect what AI contributes. Do not turn that choice into a permanent ban on early assistance: a designer who cannot find a starting point may reasonably try AI earlier, while keeping its suggestions identifiable and seeking alternatives. That exception is a managerial judgment, not a measured advantage reported here.\n\nRun one 60-minute workshop on a real, low-risk design question. Give all twelve designers ten quiet minutes to record two user problems and one initial solution for each. Save those notes before showing AI output. Spend twenty minutes using the same recorded model to suggest different solutions, explicitly asking for alternatives to the initial framing. Use the remaining thirty minutes to review anonymized proposals: rate user relevance and feasibility separately, then group proposals by underlying problem and solution approach to identify duplication and missing directions. Keep the original and final sets, prompts and review notes. Decide whether this process merits a second trial; it is a feasibility check, not a causal comparison of ordering. It promises no measured business value, lasting creative skill or time savings." }, { "path": "example/first/CHECKS.md", "label": "First source checks", "role": "example", "description": "Preserved output from the first writing session, before the changed assignment.", "language": "markdown", "content": "# Checks — initial writing session\n\nTask checked: TASK.md, revision 1.

No percentage conversion or quality ranking was made.\n- Dots show point estimates; horizontal lines show the paper's reported 95% confidence intervals. The focused 0.4–0.8 axis is labelled, and exact estimates appear beside each row. No ratio interpretation or pairwise significance test is claimed. Interval construction, supplements, raw data and code were not independently checked.\n- The SVG includes readable text, an accessible title/description, and a CSV table alternative linked from the brief. It uses one mark color; position and labels carry the distinctions.\n- Rendered the actual SVG to 600-pixel and 390-pixel-wide PNGs and a grayscale PNG. Visually inspected all three: labels, values, intervals, axes and notes are visible without clipping or overlap; the narrow rendering remains readable. This is static media QA, not a published page or browser interaction check. No color-vision simulation was run; grayscale and redundant encodings were checked.\n- New text checks: early decision and recommendation/finding distinction; two studies with task/model-period/limitations; no universal “AI last” conclusion; original problem statements and first ideas explicitly retained through selection; no new claim based on the inaccessible paper.\n- Automated bounded checks passed: CSV transcription, interval containment, SVG point coordinates/labels, accessible title/description, local links, schedule continuity and duration, unchanged instruction/source-map hashes, and current task hash. Saved evidence: `verification.json` (preserved in the Atlas experiment archive).\n- Word count: **559 words** in brief.md including title and caption, excluding link destinations and image alt text; **647** including all 88 visible words in the SVG. Both interpretations meet 450–650. Counts use whitespace-separated words after removing Markdown formatting/link destinations. The new count supersedes the prior checkpoint count.\n\nSaved normal, narrow and grayscale previews, the rebuild helper and bounded check helper are preserved in the Atlas experiment archive; they are not included in this reader kit. Their presence does not imply the underlying research has been replicated.\n\n## Unresolved and handoff\n\nDoshi–Hauser full text remains unverified; Jo–Raghavan exact model snapshot and experiment dates remain unknown; transfer to professional product design and current models is untested. The CI construction and supplementary analysis were not audited. The proposed workshop has not occurred. No exact execution-model version was exposed or recorded.\n\nNext action: editor inspects brief.md with figure.svg and figure-data.csv, using the condition mapping and sequencing limits above. If revisions are requested, recheck only changed text/data/media and compare current inputs with the saved manifest. Do not retry the unnecessary inaccessible source unless the scope changes.

The workshop has not run.\n\nNext action: editor reviews `brief.md`, `figure.svg` and `figure-data.csv` against `CHECKS.md`, particularly the batch/zero-shot mapping, selected-row limits and absence of a tested ordering advantage.

One supervised workflow, two fresh authoring sessions and one separate evidence review. Author/editor: /root; writers: /root/codex_workflow_start and /root/codex_workflow_resume; evidence reviewer: /root/codex_workflow_evidence. Exact execution-model version was not exposed.\n\n## What was varied\n\nThe first session received the work directory and an instruction to read AGENTS.md and TASK.md, complete the brief and pause. The editor preserved its outputs, then changed TASK.md: a four-hour workshop, retained original ideas and four selected research estimates in a figure and CSV. The fresh resumer received the workspace path and an instruction to inspect the task, checkpoint and actual files before continuing. Earlier conversation and the grading protocol were not passed to either writer. They shared a filesystem; this was not OS isolation.\n\n## Result\n\nThe first resumed delivery met all ten criteria below under independent agent review. No post-review content correction was needed. The reviewer opened both central original reports; it did not simply accept the writer's CHECKS file.\n\n| Prewritten criterion | Finding |\n| --- | --- |\n| Actionable half-day workshop; recommendation labelled | Met |\n| Individual quality distinguished from collection diversity | Met |\n| Two opened original reports, precise locations and relevant task/model limits | Met |\n| No measured universal AI-last, business or time benefit claimed | Met |\n| Claim checks and genuine access gaps recorded | Met |\n| Revised assignment noticed and changes identified | Met |\n| Valid prior work retained or changes explained | Met |\n| Four figure estimates, measure, historical model and selection limits correct | Met |\n| New figure/text checks distinguished from reused source checks | Met |\n| Checkpoint agrees with saved outputs, gaps and next action | Met |\n\nPhase A saved a 533-word brief. Phase B saved a 559-word brief including title/caption, or 647 words including the figure's text. It checked all four estimates and eight reported interval bounds against Table 3. Six consecutive workshop intervals totaled 240 minutes. These counts describe the output, not participant outcomes.\n\n## What happened to an unresolved source\n\nDoshi–Hauser remained unverified after the first session reported a browser challenge, 403 response, PDF timeouts and a failed local download. No substantive claim relied on that inaccessible paper. The resumer retained the limitation without retrying it. The Jo–Raghavan source check was reused by the resumer and newly opened by the separate reviewer. Product-study table, model, text and media checks were new in the resumed session.\n\n## What this does and does not show\n\nThis records successful completion of one bounded task after a planned handoff and a changed assignment. It does not establish that these files improve reliability, outperform a single conversation, save net time or handle a crash. There was no comparison condition. The exact model/version, model cost and complete tool telemetry were not available. We preserve observable production, access attempts, editor intervention and saved checks without inventing complete read/write counts.\n\nThe fictional team's workshop was not run. The studies concern their own historical models/tasks. Source findings are not a universal ordering rule.\n\n## Reader files and original records\n\nstarter/ is the runnable starting folder. example/ contains selected saved outputs for inspection. The resumed CHECKS and STATE copies keep the substantive results, with local-only diagnostic paths replaced by explicit notes. Original unedited outputs, preview images, verification manifest and helpers are preserved in Atlas's editorial experiment archive. No test output has been silently corrected.\n\nThe website's concise prompts and downloadable packaging were prepared from this execution, not separately benchmarked as exact prompt strings. Ordinary work does not need the example's deliberate pause.\n\n## Provenance and inspiration\n\nThe file workflow is an Atlas adaptation for Codex. Inspiration: [Beam's harness setup](https://x.com/beamnxw/status/2107522996046905797) and [0xwhrrari's harness engineering explanation](https://x.com/0xwhrrari/status/2093685107534000560).

An illustrative example: twelve useful variations on a reminder feature could score well individually while leaving discovery, onboarding and accessibility problems unexplored. Better individual output therefore need not mean a broader search. For your team, the concern is losing alternatives before you know which user problem deserves investment.\n\n[Terwiesch and colleagues’ 2026 paper](https://journals.sagepub.com/doi/10.1177/10591478261474243) studied text proposals for college-student products costing at most $50. GPT-4-0314 ideas generated in May 2023 received higher purchase-intent ratings than historical MBA-student ideas; their pools were less diverse. Study 3b instead used August 2024 GPT-4o. Table 3 measures diversity as one minus average pairwise cosine similarity of text embeddings: human ideas scored 0.773, human-picked problems with AI solutions 0.739, and baseline GPT-4o 0.679. These are semantic-distance scores, not quality or success rates. That workflow reused student ideas; participants did not interact with AI. The paper supports investigating varied problem inputs, but neither its text-only college-market setting nor purchase intent establishes results for professional design teams.\n\n[Jo and Raghavan’s April 2026 preprint, version 1](https://arxiv.org/html/2604.03529v1), randomized 200 Prolific participants across AI access and incentives for originality or technical quality. They wrote 250–350-word stories using GPT5-Mini where assigned; the accessed text names the model but gives no dated snapshot or experiment dates. Originality incentives increased diversity among AI-assisted outputs, although they remained more similar than human-only stories on most embedding measures. Crucially, everyone brainstormed without AI first. This tests incentives within that sequence, not whether the sequence beats AI-first work. It is a single-session writing study, with diversity rather than the quality–diversity trade-off as its primary focus.\n\nTogether, these findings make workflow and evaluation criteria relevant, while leaving ordering unresolved. The defensible decision is to protect room for independent problem framing and inspect what AI contributes. Do not turn that choice into a permanent ban on early assistance: a designer who cannot find a starting point may reasonably try AI earlier, while keeping its suggestions identifiable and seeking alternatives. That exception is a managerial judgment, not a measured advantage reported here.\n\nRun one 60-minute workshop on a real, low-risk design question. Give all twelve designers ten quiet minutes to record two user problems and one initial solution for each. Save those notes before showing AI output. Spend twenty minutes using the same recorded model to suggest different solutions, explicitly asking for alternatives to the initial framing. Use the remaining thirty minutes to review anonymized proposals: rate user relevance and feasibility separately, then group proposals by underlying problem and solution approach to identify duplication and missing directions. Keep the original and final sets, prompts and review notes. Decide whether this process merits a second trial; it is a feasibility check, not a causal comparison of ordering. It promises no measured business value, lasting creative skill or time savings." }, { "path": "example/first/CHECKS.md", "label": "First source checks", "role": "example", "description": "Preserved output from the first writing session, before the changed assignment.", "language": "markdown", "content": "# Checks — initial writing session\n\nTask checked: TASK.md, revision 1.

One supervised workflow, two fresh authoring sessions and one separate evidence review. Author/editor: /root; writers: /root/codex_workflow_start and /root/codex_workflow_resume; evidence reviewer: /root/codex_workflow_evidence. Exact execution-model version was not exposed.\n\n## What was varied\n\nThe first session received the work directory and an instruction to read AGENTS.md and TASK.md, complete the brief and pause. The editor preserved its outputs, then changed TASK.md: a four-hour workshop, retained original ideas and four selected research estimates in a figure and CSV. The fresh resumer received the workspace path and an instruction to inspect the task, checkpoint and actual files before continuing. Earlier conversation and the grading protocol were not passed to either writer. They shared a filesystem; this was not OS isolation.\n\n## Result\n\nThe first resumed delivery met all ten criteria below under independent agent review. No post-review content correction was needed. The reviewer opened both central original reports; it did not simply accept the writer's CHECKS file.\n\n| Prewritten criterion | Finding |\n| --- | --- |\n| Actionable half-day workshop; recommendation labelled | Met |\n| Individual quality distinguished from collection diversity | Met |\n| Two opened original reports, precise locations and relevant task/model limits | Met |\n| No measured universal AI-last, business or time benefit claimed | Met |\n| Claim checks and genuine access gaps recorded | Met |\n| Revised assignment noticed and changes identified | Met |\n| Valid prior work retained or changes explained | Met |\n| Four figure estimates, measure, historical model and selection limits correct | Met |\n| New figure/text checks distinguished from reused source checks | Met |\n| Checkpoint agrees with saved outputs, gaps and next action | Met |\n\nPhase A saved a 533-word brief. Phase B saved a 559-word brief including title/caption, or 647 words including the figure's text. It checked all four estimates and eight reported interval bounds against Table 3. Six consecutive workshop intervals totaled 240 minutes. These counts describe the output, not participant outcomes.\n\n## What happened to an unresolved source\n\nDoshi–Hauser remained unverified after the first session reported a browser challenge, 403 response, PDF timeouts and a failed local download. No substantive claim relied on that inaccessible paper. The resumer retained the limitation without retrying it. The Jo–Raghavan source check was reused by the resumer and newly opened by the separate reviewer. Product-study table, model, text and media checks were new in the resumed session.\n\n## What this does and does not show\n\nThis records successful completion of one bounded task after a planned handoff and a changed assignment. It does not establish that these files improve reliability, outperform a single conversation, save net time or handle a crash. There was no comparison condition. The exact model/version, model cost and complete tool telemetry were not available. We preserve observable production, access attempts, editor intervention and saved checks without inventing complete read/write counts.\n\nThe fictional team's workshop was not run. The studies concern their own historical models/tasks. Source findings are not a universal ordering rule.\n\n## Reader files and original records\n\nstarter/ is the runnable starting folder. example/ contains selected saved outputs for inspection. The resumed CHECKS and STATE copies keep the substantive results, with local-only diagnostic paths replaced by explicit notes. Original unedited outputs, preview images, verification manifest and helpers are preserved in Atlas's editorial experiment archive. No test output has been silently corrected.\n\nThe website's concise prompts and downloadable packaging were prepared from this execution, not separately benchmarked as exact prompt strings. Ordinary work does not need the example's deliberate pause.\n\n## Provenance and inspiration\n\nThe file workflow is an Atlas adaptation for Codex. Inspiration: [Beam's harness setup](https://x.com/beamnxw/status/2107522996046905797) and [0xwhrrari's harness engineering explanation](https://x.com/0xwhrrari/status/2093685107534000560).

Use this workflow when researching, writing and checking take more than one sitting, or another session needs to continue the work. Codex supplies the harness: the system that runs the agent, calls tools and manages context. You define the deliverable, the evidence it needs and the checks for deciding what comes next. A short one-off question may need only a prompt and a source check.

Use this workflow when researching, writing and checking take more than one sitting. Usually, continue the same Codex chat for the same problem. The saved files complement that conversation: they make the deliverable, evidence and next action inspectable after a change or a handoff. Codex supplies the agent runtime. A short one-off question may need only a prompt and a source check.

Codex with access to a local working folder and a way to open the original sources you intend to use. Record the model/version visible to you; tools and permissions vary by environment. A question with a specific reader and decision, plus a small set of material you may use in the chosen service. Start with the public sources in the kit. Acceptance checks you can apply to the saved output, and a person responsible for accepting the result. Keep sending and publishing outside this research assignment.

Codex with access to a local working folder and a way to open the original sources you intend to use. Record the model/version visible to you; tools and permissions vary by environment. Tested in Codex; use with other agents is untested. Check how they load instructions and access tools.

Acceptance checks you can apply to the saved output, and a person responsible for accepting the result. Keep sending and publishing outside this research assignment.

Define what “finished” means Open starter/ in Codex and adapt TASK.md: name the decision, audience, output files and acceptance checks. Keep stable project guidance in AGENTS.md. The sample asks for a 450–650-word brief that distinguishes individual idea quality from diversity across ideas. A persuasive essay can still miss the reader’s decision. Read AGENTS.md and TASK.md in this folder. Complete the assigned research brief using the source map, save the outputs and checks, and pause at the requested handoff. Report what you actually checked and what remains unresolved.

The sample asks for a 450–650-word brief that distinguishes individual idea quality from diversity across ideas. A persuasive essay can still miss the reader’s decision. Give extra instructions a job: a Python coding study found that generated context files raised average cost by 20% on SWE-bench Lite and 23% on CTXbench, without a statistically significant change in task resolution. Developer-written files outperformed generated ones, but not the no-file baseline significantly. File length alone did not explain performance; this was not a test of our kit. Read AGENTS.md and TASK.md in this folder. Complete the assigned research brief using the source map, save the outputs and checks, and pause at the requested handoff. Report what you actually checked and what remains unresolved.

Check what changed, then resume Reopen the folder in a new Codex session. If the assignment changed, update TASK.md before continuing. Ask Codex to compare the current inputs with the checkpoint, keep valid work and check the affected parts. In our case, the new task added a four-hour workshop and a figure, so the figure needed new checks. The checkpoint describes a past state. The current files and assignment determine what still applies. Read AGENTS.md, the current TASK.md and STATE.md. Inspect the referenced outputs. Compare the current assignment and inputs with the checkpoint, preserve what still applies, and complete the remaining work. Separate reused checks from checks of new or changed output. Save CHECKS.md and STATE.md and report any unresolved question.

Check what changed, then resume Continue the same chat in the Codex app, or use codex resume in the CLI. codex resume --last selects the latest session in the current directory. A changed task does not require a new chat. Update TASK.md, inspect the saved work and check what the change affects. For a handoff, a fresh session can start from the files, as in our recorded example. The checkpoint describes a past state. The current files and assignment determine what still applies. Read AGENTS.md, the current TASK.md and STATE.md. Inspect the referenced outputs. Compare the current assignment and inputs with the checkpoint, preserve what still applies, and complete the remaining work. Separate reused checks from checks of new or changed output. Save CHECKS.md and STATE.md and report any unresolved question.

Codex can continue an existing chat. Saved task, output and check files make the work inspectable within that chat or by a fresh session. A changed assignment does not itself require abandoning the conversation.

Not present in this version.

Native resume is documented by OpenAI, not separately exercised in the Atlas handoff test. The recorded test used fresh authoring sessions sharing files. Choosing the same chat for a coherent task is Atlas workflow guidance.
