Compare two annual 10-K periods with ChatGPT and check every figure

Use ChatGPT to compare two actual annual 10-K periods, then reconcile filings, verify every calculation and source, and accept or hold an analyst memo.

The big change

What changed: ChatGPT's file analysis can help organize a small, structured filing table, show calculations and draft a memo from supplied evidence.

Why it matters: Row IDs and filing locators make the proposed comparison auditable instead of leaving numbers inside a plausible paragraph.

What to watch: Amended filings, non-reliance notices and changed prior-year presentations can overturn a neat calculation. An analyst must resolve them before accepting the memo.

Check README npm scripts with a Claude Code cloud scheduled task

Set up one Claude Code cloud scheduled task to compare README npm run commands with package.json scripts, then verify manual and scheduled reports at their checked commits.

The big change

What changed: Anthropic's research-preview cloud scheduled tasks can start a full repository session on a recurring trigger. A maintainer can turn a small documentation check into a repeatable run without building a separate CI workflow.

Why it matters: A report can identify a README command whose script key is absent from the manifest. That gives the maintainer a specific line and checked commit to inspect before readers follow the instruction. A green session status alone does not establish that the comparison was correct.

What to watch: The first actual scheduled run is the test of recurrence. Its checkout can differ from the manual run's, so the maintainer must read each report against its own commit and decide whether any changed finding reflects a file change.

Build a checked Gmail triage agent for Linear and Slack

Copy a reviewed Python worker to classify permitted Gmail requests, approve exact proposals, verify Linear issues and Slack notices, then label and monitor safely.

The big change

What changed: A model can classify a bounded mailbox message and draft a route, while a person approves the source-bound proposal before separate Linear and Slack requests.

Why it matters: The journal keeps one action identity for each mailbox and Gmail message ID across policy revisions, and records uncertain requests before they reach another service.

What to watch: The reader must verify the actual issue, channel notice and final Gmail label. A stop blocks later claims but cannot recall a request already admitted or in flight.

Set and check Vercel spend alerts for an AI-built app

Set a Vercel team spend amount, choose your alert thresholds, and record the AI app project's usage without changing existing pause or webhook actions.

The big change

What changed: Vercel's Spend Management lets an eligible team set an On-Demand Budget and notify its Owner or Billing members at 50%, 75% and 100% of the amount. Its Usage view can filter to the AI app's project.

Why it matters: The amount covers metered use across the whole team. A release owner needs both the team total and the app's project breakdown before deciding what an alert means or who will respond.

What to watch: Existing pause or webhook actions can fire when the amount is reached. Lowering it below spending already accrued this cycle can trigger those actions at Vercel's next check. Inspect them before changing the amount.

Edit your own video takes into one checked film with Claude Code

A documentation-based guide to turning real owned takes into one reviewed film with Claude Code and Video Use: source-linked cuts, optional graphics, preview, final MP4 and full human playback.

The big change

What changed: Video Use gives a coding agent a documented path to transcribe multiple takes, propose an edit, render from a source-linked edit decision list (EDL) and inspect the output.

Why it matters: An editor can review the chosen source intervals and cut strategy before a final film is made.

What to watch: Transcription sends extracted audio to ElevenLabs Scribe; transcript and sampled-frame context may reach the configured Claude model. Local rendering does not make those analysis steps local, and automated checks do not establish rights or editorial quality.

Make an editable restaurant menu and check its phone and print files

Use an approved item sheet to build an editable Canva restaurant menu, then check the actual phone and print PDFs before the owner accepts either file.

The big change

Canva's design tools let an owner turn an approved menu record into an editable layout and two PDF types. The useful control is the chain from the current item sheet through the master to the actual phone and print files. AI can arrange or suggest content, while the owner supplies and checks every menu fact. Phone reading and printer acceptance happen outside Canva's layout suggestion and must be checked on the files that will be used.

How to run RADAR's bundled abdominal CT research demo

A documentation-led guide for authorized imaging AI researchers to run RADAR's supplied abdominal CT case, verify a fresh score CSV and understand what the scores cannot show.

The big change

What changed: RADAR's public repository supplies a concrete, local inference demo for one bundled NIfTI CT case and a CSV of finding scores.

Why it matters: A researcher can check whether a fresh local run produces a labeled score file. That check says nothing by itself about diagnostic accuracy, patient risk or clinical readiness.

What to watch: The path requires suitable CUDA hardware, the right model files and authorized use of the supplied case. The output remains a research score file, not a clinical result.

Original story: guide

Run two Claude Code coding sessions in separate Django worktrees

Use two Claude Code sessions for approved Django coding tickets in separate Git worktrees. Verify distinct SQLite files and ports, then review and test the combined branch before cleanup.

The big change

What changed: Claude Code supports parallel sessions in Git worktrees, so two bounded coding tasks can use separate branches and files from one repository. Their runtime dependencies still need separate configuration.

Why it matters: A developer can review each ticket on its own branch while keeping the main checkout available. Distinct database paths and ports make each local result attributable to the right task; Git alone cannot provide that boundary.

What to watch: The decision rests on the integrated migration path and both acceptance checks. A test that passes against one branch's database says little about the merged schema or the other ticket's behavior.
