AI reads medical records, finds nexus evidence, drafts 38 CFR-aligned claims, and packages everything VA-ready in minutes instead of months. ### [Hospital Ledger](https://hospitalledger.com) Every U.S. hospital price file, in one CC0 dataset · Status: Live Federal rule (45 CFR § 180) requires every U.S. hospital to publish a machine-readable file of standard charges and payer-negotiated rates. CMS doesn't aggregate them. Commercial aggregators paywall their data behind NDAs. Hospital Ledger is an open-source, public-good crawler that pulls 5,426 facilities and 7,191 MRF URLs into a single CC0 dataset — alive/dead status, file format, last-updated date, and the parsed prices behind them. CMS-complaint workflow planned for non-compliant hospitals. ### [SF Permit Navigator](https://sf-permit-detector.barkleesanders.workers.dev) Find the right SF permit in plain language · Status: Building Cloudflare Worker + Hono prototype showing the front door SF permit applicants and staff are asking for: AI matching from plain-language descriptions, intake workspace, dynamic per-permit checklists, public status routing across DBI / Planning / Fire / DPH, demo lab for uploads, fees, plan review, and inspections. Built from public sources — labels every place a city API or credential is still needed. PermitSF stays the official system of record; this is the broader catalog and reform tracker beside it. ### [ImproveBayArea](https://improvebayarea.com) One-tap 311 for the Bay Area · Status: Live One report form for every Bay Area city — pothole, graffiti, encampment, abandoned vehicle, dumping — routed automatically to the right 311 backend (Verint, SeeClickFix, Open311) for SF, Oakland, Berkeley, Alameda, Emeryville, San Leandro, Walnut Creek, San Rafael, Vallejo, and more. No login, no app store, no city-by-city download. Built solo on Cloudflare Workers. Civic tech doesn't have to take 18 months and a grant — the APIs are public, the cities are public, the friction is the design. ### [NPS Report](https://nps-report.barkleesanders.workers.dev) One-tap maintenance & safety reports for all 435 national parks · Status: Live Report a broken railing, a safety hazard, or a busted restroom in any U.S. national park — Yosemite to the National Mall — the way ImproveBayArea does it for city 311. Snap a photo and AI writes the title, category, and description; GPS routes the report to the nearest of 435 NPS-covered parks; it's delivered to that park's ranger mailbox through the Park Service's own contact form. No login, no app, no new email infrastructure — built solo on Cloudflare Workers + Hono. The NPS has no public report API, so this is the working proof that citizen-powered park upkeep is one form away. ### [SF Income Verify](https://sf-income-verify.barkleesanders.workers.dev/#how-it-works) Prove income once, apply to any affordable home · Status: Building Civic-tech demo: a centralized income-verification entry point for SF affordable housing. One Plaid payroll check, one 12-character reference, valid for 90 days. Landlords see only an AMI bracket — never the figure, employer, or bank credentials. Cloudflare Workers + Hono + D1, hashed-only storage, GDPR/CCPA endpoints, listings mirrored from SF's public DAHLIA feed. Not affiliated with MOHCD — just showing what's possible when the bottleneck shifts from supply to paperwork. ### [Treasure Island Power](https://www.treasureislandsfpoweroutages.com) Exposing infrastructure failure · Status: Live 500 homes. 529 outages in 25 years. One outage every two weeks. We track every failure, publish the data, and hold SFPUC accountable. ### [ESBE Tech](https://esbe.tech) Honest computer repair · Status: Live $60/hour. No diagnostic fees. No hidden costs. Most fixes take 3 hours. If we can't fix it, we'll tell you who can. ## Field Reports - [The Claude Ledger](https://barkleesanders.com/blog/claude-ledger-2026-04-15/) - A forensic accounting of 30 days of Claude Code usage. 1,193 sessions, 802 displaced hours, $160,400 of senior-engineer-equivalent labor delivered for $400 of subscription cost.

Thirty days. 401x the money back. Forensic walk of every Claude Code session on disk between March 16 and April 15, 2026 returns a single defensible number: $400 of Claude Max subscription displaced an estimated $160,400 in senior-engineer-equivalent billable labor. The records show what the work was, how long it would have taken a person, and who that person would otherwise have been. | Metric | Value | | --- | --- | | SUBSCRIPTION_COST | $400 | | EQUIVALENT_LABOR | $160,400 | | MULTIPLE | 401× | ## By the wire. Every number below was counted, not estimated. Reproducible from disk on this machine. ```text $ python3 walk-sessions.py ~/.claude/projects/ # window: 2026-03-16 → 2026-04-15 (30 days) sessions.main_files 219 sessions.subagent_files 974 sessions.combined 1,193 messages.user 24,712 messages.assistant 36,361 tool_calls.total 21,556 tool_calls.bash 13,150 # 61% of work tool_calls.read 2,863 tool_calls.edit 1,883 tool_calls.write 596 tool_calls.grep 722 tool_calls.agent 465 bytes.transcript_total 4,605,427,994 # 4.4 GB chars.user_input 19,213,160 chars.assistant_output 3,690,872 # 5.2x tighter cadence.sessions_per_day 7.4 cadence.busiest_day 2026-04-13 (20) exit 0 ``` ## How 802 hours got computed. Each tool call is priced at a conservative manual-equivalent duration — the time a competent senior engineer would have spent doing the same work without assistance. Reads include locating the file, opening it, scanning for context. Edits include diffing the change, testing it, undoing the typo. Sub-agent runs are priced as the smallest investigation a human could have completed in their place. Terms are deliberately stingy. ```text 13,150 bash × 1 min = 219.2 hr 1,883 edits × 5 min = 156.9 hr 2,863 reads × 2 min = 95.4 hr 596 writes × 10 min = 99.3 hr 465 agents × 30 min = 232.5 hr ──────────────────────────────────── Σ labor displaced ≈ 803.3 hr ≈ 100 working days ≈ 5 months full-time ``` ## Fourteen production systems shipped, repaired, or migrated.

The 802 hours did not come from one job. They came from six. Each role below is a distinct specialist that would otherwise have been retained, contracted, or become. Total fully-loaded annualized salary equivalent: $620,000. | Metric | Value | | --- | --- | | ANNUALIZED_SALARY | $620,000 | | SUBSCRIPTION | $2,400 | | DELTA | 258× | - **Senior Full-Stack Engineer** ($180,000 / yr) - **DevOps / SRE** ($170,000 / yr) - **Marketing Analyst** ($85,000 / yr) - **Legal Paralegal** ($75,000 / yr) - **Genealogy Researcher** ($60,000 / yr) - **Tax Preparer** ($50,000 / yr) ## 465 investigations Barklee never had to run himself. Sub-agents are how a single operator keeps a context window in good order. Each one is a colleague spun up for a single question, given full read-write access to the codebase, and dismissed when the answer comes back. Below is what the squadron actually ran. - **Explore** (196 missions) — Codebase reconnaissance, file pattern hunts, "where is X handled" investigations. - **Carmack** (150 missions) — Empirical debugging, root-cause investigations, build-test-verify loops. - **General-purpose** (88 missions) — Open-ended research that did not fit a named specialty. - **Plan** (28 missions) — Implementation strategy with file paths and architectural trade-offs. - **Frontend-developer** (2 missions) — React + responsive design pattern work. - **Claude-code-guide** (1 mission) — Meta-question about the harness itself. ## The transcripts on disk are longer than War and Peace, six hundred times over. 4.4 GB of dialogue is an unusual artifact. Not a chat history in any colloquial sense — the working notebook of a single operator who, over thirty days, dictated 19.2 million characters of intent into a machine and received 3.7 million characters of considered response in return. The asymmetry is the point. The model spoke five times less than its operator, which is the inverse of how human consultants bill. Where a senior engineer might write a memo to justify two hours of work, this engagement produced two hours of completed work to justify one short reply. The top three tools, in the order reached for, were Bash, Read, and Edit — the trinity of actual engineering — occupying 84% of all tool calls. Everything else fits in the remaining 16%. The work was, overwhelmingly, hands on the keyboard. ## Senior-engineer-equivalent labor, delivered for $400. The arithmetic is the boring part. The interesting part is that the work is on disk, the projects are running in production, and the bill is paid through the end of next month. The audit closes here. | Metric | Value | | --- | --- | | WINDOW | 30 DAYS | | DELIVERED | $160,400 | | COST | $400 | > What you can prove from the receipts is not the same as what the receipts mean. The receipts are conservative. The meaning is that one person now ships at the cadence of a team. ## Related - [Field Reports (blog index)](https://barkleesanders.com/blog/) - [Home](https://barkleesanders.com/)
