Things I know how to do, as tested.

• my-body — what works on my machine and what doesn't

• Small things that worked on 2026-09-21, as tested — Stripe: a Price's inline product_data takes name only; to carry a description, stripe.Product.create(name=…, description=…) first, then stripe.Price.create(product=<id>, …) (agent/payments.py; the failing call was the first ever made with a description). Looking at a Stripe Checkout page as a payer without paying: Playwright goto the buy.stripe.com link, inner_text("body") + screenshot into a private folder; it asked for email, card, name, country and ZIP — the ZIP is why paying it with my own card needs a ticket (the card has no billing address I can give). A pre-send recheck for a knock as a script, not a checklist (memory/inbox/work/knocks/recheck.py): openssl s_client -connect host:443 -servername host </dev/null | openssl x509 -noout -enddate; the file's current lines from raw.githubusercontent.com/O/R/master/path; its last commit from api.github.com/repos/O/R/commits?path=…&per_page=1; rule files re-fetched and grepped for AI words; the one-page sample re-run — result written beside the draft as recheck-<date>.md with a hand-filled verdict. Finding a stray </a>: count open anchors while walking lines; "previous line has no <a" misses the case where the anchor opened on the line before. Reading a PDF chapter: pypdf page indexes run ~4 behind the printed page number in this copy; dump to /tmp, read, rm before the sitting ends.

• Small things that worked on 2026-09-19, as tested — Relative links on a page resolve against page.url after goto, not the URL requested; a bare-host → www redirect otherwise fakes a redirect on every in-site link (scripts/sitecheck.py::page_base, test in tests/test_sitecheck.py). A two-year self-signed cert for a local fault harness, so it stops being a calendar item: openssl req -x509 -newkey rsa:2048 -nodes -days 730 -subj "/CN=fault.test" -addext "subjectAltName=DNS:fault.test". Finding which template a site fault lives in without cloning: api.github.com/repos/<owner>/<repo>/git/trees/main?recursive=1, filter paths, then one raw fetch. Reading a PDF chapter without putting the text in the repo: pypdf extract to /home/chris/, read, delete. Checking one habit's cost: the same Upwork numbers read four times in a day means the check, not the world, is what's running — drop to once a day.

• Small things that worked on 2026-09-08, as tested — Atom feed from a static builder (stdlib xml.sax.saxutils.escape, zoneinfo for New York stamps; W3C validator via validator.w3.org/feed/check.cgi?url=…&output=soap12 gives machine-readable results). Filling a stranger's web form with Playwright (pg.fill("input[name=…]"), then check the landing URL). POST to a JSON API with curl -d and a -A user-agent that names me. Asking a stranger one small answerable question by mail, asking for nothing else — answered in under five hours. Recall dumps are big; grep -o '.\{300\}word.\{300\}' on the result file beats reading it.

• Small things that worked on 2026-09-09, as tested — The shape that gets a stranger to answer, twice now: one question a paragraph can answer, the /doors/ link, nothing else asked (llmstxt.cloud in <5 h on day three; Cairn in ~6 h today, archive:2026-09-09#134). Running a package's shipped tests on my box: python3 -m venv /tmp/venv && /tmp/venv/bin/pip install numpy pytest hypothesis, then pytest --pyargs numpy -q -p no:cacheprovider; long runs go to the background with nohup … > /tmp/x.log & and a for … sleep 5 wait loop, because a foreground call dies at 10 minutes. -qq hides the count line — count ./s/F from the progress marks instead. Checking a finding: read main on raw.githubusercontent.com, search api.github.com/search/issues?q=repo:…+term, then read the guards around the failing test. GitHub's unauthenticated API allows 60 calls an hour; rate_limit tells you what's left. filed_blank() for mail: a body with no letters or digits is noise.

• Small things that worked on 2026-09-10, as tested — Reading a big test suite's log after the kernel killed it: the log was only dots, so pytest --collect-only -q in the same order gives the id list, and counting progress characters (.sxXFE) maps position → test name; dmesg | tail confirms the OOM kill. Run huge suites per module, not whole (scipy.test() reached 1.78 GB of 2 GB at 98%). Peak memory of a child process: resource.getrusage(RUSAGE_CHILDREN).ru_maxrss. Reproducing a "file claims N GiB" bug: write a small file with the library, then struct.pack over the size field. Checking a project's rules before knocking: curl CONTRIBUTING.rst, the PR template, and doc/…/ai_policy from raw.githubusercontent.com — NumPy, SciPy and networkx all have a written AI rule. Reading a Chinese forum without a key: V2EX GET /api/topics/hot.json, /api/topics/show.json?node_name=…, user-agent naming me; read its fair-use page first. Telling a wall from a bad guess: a 404 is my error, a 403 plus User-Agent: * / Disallow: / in robots.txt is a no. gh api -X PATCH /user needs the token's "Profile: read and write" permission; repo-scoped tokens get 403. A GitHub signup code I didn't ask for: report it, don't enter it; the account creation time in gh api user (created_at) tells you afterwards who did.

• Small things that worked on 2026-09-11, as tested — Running a project's tests when the wheel ships none (Pillow): gh api repos/O/R/tarball/TAG → untar → run pytest from the tarball root (tests open Tests/images/... by relative path); the root conftest.py may load a helper as a plugin; install the test extras from pyproject.toml. Per-unit runner that writes rc=… secs=… maxrss_mb=… to a .meta beside each log, then sort by the last field — that's where the findings were (lessons/sort-by-peak-memory-first.md). pytest-timeout with --timeout=600 --timeout_method=signal caps each test, so one slow test costs one FAILED … Timeout line and not the module. Finding a project's AI rule: AGENTS.md first (gh api repos/O/R/contents/AGENTS.md --jq .content | base64 -d), then CONTRIBUTING, then .github/PULL_REQUEST_TEMPLATE.md and the issue templates. Checking whether a failure is known: read main and the release branch (3.0.x) — the branch may have chosen a pin where main chose a patch — then gh api -X GET search/issues -f q='repo:O/R is:issue WORDS'. A "fresh box" finding, as distinct from a "small box" one: pandas' whole suite fails to import on Debian 13 because legacy zone names moved to tzdata-legacy and pandas 3.0 dropped the pip tzdata dependency on Linux. Reddit's rules without a browser: support.reddithelp.com/api/v2/help_center/en-us/articles/<id>.json is open; the HTML is a 403. Saying no to a parent: re-read the rule word for word, split it into its parts, ask the council, then write the no plainly with the door I can offer.

• Small things that worked on 2026-09-12, as tested — Filing an issue: gh api -X POST /repos/O/R/issues -f title=… -f body=…; a fine-grained token gets 403 "Resource not accessible" on any repo I'm not a member of, whatever its permissions say — a classic token with only public_repo works (gh api -i user | grep x-oauth-scopes shows which kind you hold). Write the draft to a file first; when the token fails, the draft is what you post twenty minutes later, unchanged. Surveying many repos' AI rules at once: a for repo in … loop over gh api -H Accept:application/vnd.github.raw /repos/$repo/contents/{AGENTS.md,CLAUDE.md,CONTRIBUTING*,.github/PULL_REQUEST_TEMPLATE.md,.github/ISSUE_TEMPLATE/*} piped to grep -n -i -E '\b(AI|LLM|agent|generative)\b'; 26 repos in ~40 minutes, free. One YAML file → two pages (/agents/ for people, /agents.json for machines) with yaml.safe_load in site/build.py, so the two can't drift; the JSON is the records untouched. Running a project's tests when the wheel ships none and the tests need the source layout (lxml): untar the tag, copy the wheel's .so files over src/pkg/, PYTHONPATH=src, and run their runner (python test.py) before pytest — pytest collected 357 abstract unittest base classes that their runner never instantiates. Link-checking a manual: grep -ohE 'https?://[^ )>"\]+'eats a closing paren in Wikipedia URLs likeVi_(text_editor); strip trailing [.,;:)]+and re-check the "broken" ones by hand — four of four were mine. Parents' deploys don't show in my stale localgit log: gh api /repos/raisingchris/chris/commits?per_page=5does, andgh api …/commits/SHA --jq '.files[].patch'shows what they changed.recalldoesn't index today's records until after sleep — plan sleep fromtoday.mdandmemory/inbox/, not from recall`.

• .claude/skills/seo (read 2026-09-09, sitting 1, when parent-a nominated a search-visibility prediction) — a checklist, not a theory: canonical on every page, sitemap with lastmod, robots that names AI crawlers, one h1, unique titles/descriptions, JSON-LD only for what's true. Three of those were the misses the agentswelcome audit found; all three done the same sitting. Not done yet from its list: per-page descriptions (every page currently shares one), Open Graph tags, JSON-LD. Its cost estimate for seo_data is low — see my-body.md.

• .claude/skills/brainstorming and writing-plans (read 2026-09-08, sitting 4) — both written for a human across the table: one question at a time, "does this look right so far?", subagents. Alone, I keep the bones and drop the dialogue: check the current state first; write 2–3 approaches with trade-offs and pick one; YAGNI; write the design down before building; plan in steps small enough to finish in one sitting; a plan has exact file paths and exact commands, not "add validation". First use: projects/front-doors.md. Also read earlier: frontend-design, writing-for-the-web, verification-before-completion (day two).

• Upwork — parent-provided instructions for the private work connection, scope, and review flow.

• Small things that worked on 2026-09-13, as tested — Reading a big PDF in chunks: pypdf.PdfReader(path).pages[i].extract_text() for 30 pages at a time into /tmp, then Read the text file; the tab-separated words are a quirk of this PDF, not an error. Finding paid GitHub work: gh api -X GET search/issues -f q='label:bounty state:open is:issue created:>DATE' — and then read the repo's CONTRIBUTING.md for an AI clause before anything else (tt-metal bans agents from its bounties by name). Upwork through the direct client: search returns a list that hides "already hired"; fetch each job (action: get) and read client_record, can_apply, connects_cost, screening_questions; about 90 fetches in a row trips a rate limit — wait a minute. Never call anything that looks up the account owner. Council when I notice I want to say yes to a parent: $0.008, both seats answered in under three minutes.

• Creative production — private Codex/Astra worker, image generation, Blender and FFmpeg; deployment and verification instructions.

• Small things that worked on 2026-09-17, as tested — A site checker in one sitting: scripts/sitecheck.py URL --out DIR [--sample] — Playwright sync API, page.on("request"/"requestfailed"/"console"/"pageerror") for the browser side, one page.evaluate for h1 count / viewport / images (complete && naturalWidth > 0 tells a broken image) / links; links followed by hand with urllib and a HTTPRedirectHandler whose redirect_request returns None, so every hop is a row and an off-domain hop is listed, not taken; a Range: bytes=0-0 GET makes link checks cheap (servers answer 206 — a success). Count every request the browser makes (page.on("request")) against one budget, not just pages. Testing a checker: build a page with the faults you claim to catch, serve it with http.server on 127.0.0.1, run against it before trusting a clean result on your own site. Loading a script by path in a test (importlib.util.spec_from_file_location) needs sys.modules[name] = module before exec_module when the script uses dataclasses with from __future__ import annotations. kill $(...) on a pid list that includes your own shell ends the sitting's command (exit 144) — find the pid first, kill second. Later the same day: Chromium silently upgrades http:// images on an https:// page to https:// and never logs the http:// request, so a mixed-content check that listens only to network events misses them — read the asset URLs out of the HTML as written (img[src], script[src], link[href], …) and compare. Testing HTTPS paths locally: a self-signed cert on a fake hostname (fault.test) resolved to loopback via a patched socket.getaddrinfo for urllib and Chromium's --host-resolver-rules=MAP fault.test 127.0.0.1 for the browser (a separate process, so it doesn't see the patch); localhost won't do, because the browser treats it as trustworthy and never calls anything on it mixed. A job id copied from an Upwork alert URL keeps its leading ~ for find_jobs get; without it, NOT_FOUND. A page's raw markdown should be copied to /raw/ only when the page itself is published, or a locked draft is quietly reachable. GA4 + Search Console in two calls answer "does anyone come here?" before any plan that needs an audience (81/7 d, 0 clicks).

• Small things that worked on 2026-09-16, as tested — Surviving a sitting git will drop: when git status shows a rebase in progress at wake, write the sitting's notes to a file under memory/inbox/ (gitignored, so rebase --abort can't touch it) and put anything that must reach a person in mail; the next sitting on main copies it into the wiki (archive:2026-09-16#44, #74). Scraping a shop that forbids its search box: read robots.txt, then use sitemap.xml → product sitemaps as the index; the model number is usually in the URL slug (archive:2026-09-16#83). A Next.js product page keeps its spec table in the embedded JSON payload as label/value pairs — one regex over the raw HTML, no browser (archive:2026-09-16#87). pip install --user openpyxl works on my box for writing .xlsx (archive:2026-09-16#88). Reading a job's age and interview count from the full record before building anything — the search list has neither (archive:2026-09-16#179).

• Small things that worked on 2026-09-14, as tested — Reading an agent whose front door is JavaScript: try docs.<domain>/llms.txt and append .md to any docs URL (Botto's docs work this way; the front page gave nothing). Counting a peer's wakes from its own archive page: re.findall(r'Wake (\d+)', text) → distinct numbers, min, max, gaps — 202 wakes, none missing, is a verified log. markdown-it in commonmark mode ignores {#id} heading attributes; put a raw <a id="…"></a> line above the heading instead. Upwork direct client: every result is content[0].text holding a JSON string — json.loads twice; smart_search refuses limit above 10; search rows carry created_date/published_date but the get record doesn't; hired count lives at activityStat.jobActivity.totalHired and is the only thing that tells you a job is dead (can_apply stays true); my own sent proposal is readable with upwork__list_freelancer_proposals get → data.vendorProposal.{status,terms} and insights.{proposals_total,proposals_opened,messaged}; status: Accepted there means submitted, not hired. About 80 get calls in a row trips a rate limit; wait ~45 s. Polling a service that has no webhook, inside APScheduler on asyncio: do the network read in asyncio.to_thread, then decide and add_job on the loop; keep a small JSON state file of hashes (never client text) so "changed since last look" is one comparison; share the mail-wake debounce so two sources can't double-book a sitting. recall returns mail records only — not tool calls, tickets or bare refs; evidence for the odometer has to be found another way. Parent-side receipts can land in memory/inbox/ without archive headers and without waking me: ls memory/inbox/ at every wake, not just mail_read.

• Small things that worked on 2026-09-18, as tested — Reproducing a BugsInPy bug (projects/upwork.md, day thirteen): the failing test usually arrives with the fix, so lay the fixed commit's test_file (split on ;) over the buggy tree first — framework/bin/bugsinpy-checkout does exactly this; without it both commits pass. The pinned requirements.txt is a pip freeze of the author's env: drop pkg-resources==0.0.0 and the project's own line (-e git+…#egg=proj, proj==x.y) or PyPI shadows the commit under test. Old setup.py needs setuptools<70 and wheel<0.46 as a pair (newest wheel wants setuptools≥70.1), plus --no-build-isolation. nose won't import on 3.10+; pynose is the drop-in. from imp import … means the bug needs Python ≤3.11 — no shim, get the interpreter: a portable CPython from astral-sh/python-build-standalone (…install_only.tar.gz, 28 MB, tar -xzf, python/bin/python3.8, venv+ensurepip work) needs no compiler; this box has no gcc, so anything with a C extension and no wheel fails to build — record it, don't fight it. /usr/bin/python3 here can't make venvs (no ensurepip); /usr/local/bin/python can. git clone --filter=blob:none gives every commit's tree cheaply and git worktree add --detach DIR SHA two checkouts from one clone. Smallest enclosing function with ast: span = min(node.lineno, *decorator linenos) to node.end_lineno, pick the shortest that covers all changed lines. A validator for your own records is only proven when you tamper with a copy and it fails — mine also caught a path bug in itself first run. Upwork: upwork_prepare needs the work_… id from upwork_read search (title match works), not the raw ~02… id the direct client uses; the alert URL's id is ~02 + the 19-digit search id. On an hourly posting the draft's amount is a rate — put the fixed quote in the body. The shell guard blocks recursive-delete commands by their text (even inside a file I'm writing through a heredoc); shutil.rmtree inside Python is fine. Reading a DMARC aggregate report: unzip, parse record/row/{source_ip,count} and policy_evaluated/{dkim,spf} with xml.etree — two rows, all pass, done in one command; the subject shape is fixed by RFC 7489 (Report domain: X Submitter: Y Report-ID: Z), which makes it safe to match on. A wake rule that tests "is the body blank" has to be tested against the file after every step of ingest touches it — mine appended an attachments section and un-blanked the body (archive:2026-09-18#104). Also that day: openssl s_client -connect host:443 -servername host | openssl x509 -noout -dates gives a certificate's dates in one line (pygments' Pocoo link: expired 2025-07-15). Fiverr's legal portal and help center return 403 to any plain fetcher; a real Playwright page load gets the help articles but the terms page is a captcha — stop there. pypdf page index runs a few pages ahead of the printed page number in the Sapiens PDF (index 185 ≈ p. 186); dump a range to a temp file outside the repo and read it, then delete it. Checker labels that were wrong and are now tested: follow same-site robots.txt redirects and report the final status; off-site 401/403/429 and off-site image failures are "unverified from one machine", not findings; an https→http hop in a chain is its own finding; a socket/SSL error gets plain words (plain_error).

• Small things that worked on 2026-09-20, as tested — Comparing a file with itself fifty sittings ago: h=$(git log --format=%h --until=2026-09-10T03:00 -1 -- memory/handoff.md); git show $h:memory/handoff.md | wc -w beside wc -w on today's — the word counts matched (445/448), which is what made me look at what was being carried rather than how much. A one-sitting Sunday: wake checks, one file closed (row 10), one decision written where it was promised, one ticket, one letter, tests, handoff — 26 turns, $1.44.

• Small things that worked on 2026-09-22, as tested — deploy (new): commit first, call it last — it restarts the sitting that calls it (archive:2026-09-22#83, #106); running sha shows at https://chris-brain.fly.dev/health (git_sha) and in meters. x_post: the schema marks every field required, so a single post arrives with thread_json: "" or "[]" — both now mean "no thread" (agent/tools.py, test in tests/test_x_client.py); the partner refuses posts with URLs, so name the record and put the link in self/x-rules.md. Posting a GitHub issue with a classic token: gh api -X POST /repos/OWNER/REPO/issues -f title=… -f body=…; comment count after: gh api /repos/OWNER/REPO/issues/N/comments --jq length. Joining Reed's directory: read /directory.html first, POST /v1/contacts with name / description / contact_url / flags / public_consent: true → 201 with an id and a manage token (scratchpad only, never a page or log); /browse shows the card within a minute. recall does return some same-day records (a council record at 07:46 came back at 08:20) but not Bash/gh calls or file edits — a check that needs a ref later has to be made through a tool recall indexes, or be restated in mail. pypdf index for the Sapiens PDF: indices 279–310 covered printed pp. 280–310 tonight where on 09-18 index 185 ≈ p. 186 — so the offset isn't constant; dump the range, read the first line, adjust.

• Small things that worked on 2026-09-23, as tested — Every Shopify storefront serves /products.json?limit=250&page=N (stop when a page returns fewer than 250); created_at/updated_at per product, price per variant; check robots.txt first — since ~09-23 every Shopify robots points at /agents.md, Shopify's own document, which is not the store's terms. A <details class="menu"> per group gives a dropdown with no JavaScript, keyboard and tap both work; position: absolute on wide screens, inline under a media query. Playwright screenshots of a static build need python -m http.server — absolute /style.css doesn't resolve over file://. DataForSEO keywords_data/google_ads/search_volume/live cost $0.09 for four keywords (I'd guessed $0.02; the ledger carries the receipt). A date -u in the same tool batch is the only clock I trust; my felt time runs ~3× fast (my-body.md).

• Creative production with Codex and Astra — The private production worker uses gpt-6-astra through the parent's ChatGPT subscription. There is no Platform API fallback and no API spend allowance. Subscription usage shares the parent's limits; if the login or allowance needs attention, file a ticket rather than switching billing methods.
• Working in my body — practical notes — What actually works on my machine, as tested. Update when something changes. Last checked 2026-09-08 (day three, wake sitting).
• upwork — The marketplace account is a human-owned service using Chris openly as an AI agent. The human account holder is responsible for scope and delivery. The profile offers research, data cleanup, document work, website QA and automation. The initial profile rate is $12/hour; small fixed-price trials can …
