How to get it
These run inside the Snappy workspace. Want this working in your business? I set skills like this up with you, in one focused week.
For developers how this skill is built, graded, and how it runs
at a glance- the short version
what's inside - the parts that make up a skill 2/4 present
A skill is just a few plain-text files. Only the main one is required. The rest are optional, added as the work needs them. This is what the skill is made of; how it runs is just below.

how it's graded - what counts as a good run 4 criteria · 3 deterministic · 1 judge
Each row is one thing a good run has to get right. deterministic means a quick check decides, pass or fail. judge means the AI reads the result and rates it. Grading each piece on its own (instead of one overall score) shows exactly where a run fell short, so the fix is obvious.
how it runs - the shared frame every skill uses 5/5 present
Every skill runs the same way. One part does the work, a separate part checks it, and a short loader hands the AI exactly what it needs for the job. Anything this skill doesn't use shows a one-line note saying why, on purpose, not by accident.
state/log/evals.ndjson - ALWAYS unescape GOOGLE_SERVICE_ACCOUNT_KEY literal \n to real newlines before signing — state/lib/sheets.ts does this for you, do not bypass
- NEVER set sendNotificationEmail: true on shareSpreadsheet without explicit instruction — Robert relays the URL in the ray-update body, not via Google's mailer
- The service account is the implicit OWNER of every sheet it creates. Robert and Ray cannot become owners without domain-wide delegation. Plan accordingly.
- Use the lib's exported functions — do NOT roll your own JWT or call googleapis directly elsewhere in the codebase
what it has learned - fixes written back in over time sample
When a run hits something this skill didn't handle, the fix gets written back into the skill so it doesn't happen again. FIXED means it was corrected on the spot. LOGGED means it's queued for a bigger rewrite. Either way, the skill gets a little better and never makes the same mistake twice.

how the work flows- who makes it, who checks it
import from `state/lib/sheets.ts` — `createSpreadsheet`, `shareSpreadsheet`, `writeRows`, `readRows`, `getSheetsClient
npx tsx state/lib/sheets.ts` (import-check) and `npx tsx state/lib/sheets.ts read <id> <tab>` (independent fetch as auditor)
SKILL.md- the skill, written out in plain English
sheets
Google Sheets surface for snappy-os. Service-account JWT auth - no OAuth dance, no per-user consent screens. Used to give Ray (and other clients) a read-only window into snappy-os data without standing up a dashboard.
The actor (this lib) writes; the auditor is an independent reader. For the business-tracking sheet specifically, the auditor is readRows() from a fresh process that confirms the headers landed and Ray's permission resolved.
See state/lib/sheets.ts for the full API surface.
Steps
getSheetsClient()- JWT-authenticated{ sheets, drive }clients. Cached per process.createSpreadsheet(title, tabs, opts?)- create workbook, write header row per tab, bold header. Returns{ spreadsheetId, spreadsheetUrl }.opts.parentFolderIdoverridesGOOGLE_DRIVE_PARENT_FOLDER_ID; must be set to avoidstorageQuotaExceeded(see Pre-flight above).shareSpreadsheet(spreadsheetId, email, role?)- Drive permission grant.roledefaults toreader. No notification email by default.writeRows(spreadsheetId, tabName, rows)- append rows under the headers.USER_ENTEREDso Sheets parses dates/numbers natively. Phase B cron uses this.readRows(spreadsheetId, tabName, range?)- read raw 2D string array. Used as the independent-fetch auditor.
Eval
Actor: createSpreadsheet, shareSpreadsheet, writeRows in state/lib/sheets.ts. Auditor: readRows() from a fresh process - confirms header row matches the requested columns; for share, an HTTP HEAD against the spreadsheetUrl from a non-authenticated session confirms the URL resolves.
Score convention:
| Outcome | Score |
|---|---|
| Workbook created + all tabs present + Ray shared | 1.0 |
| Workbook created + tabs present, but Ray's email unknown (service-account-only share) | 0.5 |
| Auth failure / API error / missing tab | 0.0 |
storageQuotaExceeded (GOOGLE_DRIVE_PARENT_FOLDER_ID not set or SA not shared on folder) | 0.0 |
| "The caller does not have permission" (SA lacks Drive access or Drive API not enabled) | 0.0 |
Pre-flight (run before any createSpreadsheet call)
- Drive storage - the service account
xano-automation@snappy-424813.iam.gserviceaccount.comhas no Drive storage quota of its own. Creating a sheet in the service account's root always throws403 storageQuotaExceeded. Fix: setGOOGLE_DRIVE_PARENT_FOLDER_IDin.env.cacheto a Google Drive folder that Robert owns and has shared with the service account (Writer). Then passopts.parentFolderIdtocreateSpreadsheet- the lib plucks the env var automatically ifopts.parentFolderIdis not supplied. - Permissions - if
createSpreadsheetreturns "The caller does not have permission," the service account has not been granted access to the parent folder (or Drive API is not enabled in the Cloud project). Share the target folder with the SA email and verify the Drive API is enabled atconsole.cloud.google.com.
Gotchas
GOOGLE_SERVICE_ACCOUNT_KEYin.env.cachearrives with literal\n- the lib unescapes to real newlines before handing to the JWT signer. If you bypass the lib and roll your own, OpenSSL throwsDECODER routines :: unsupportedwith no useful detail.- Service account is the implicit owner of any sheet it creates. Robert and Ray cannot become owners without a domain-wide delegation step the lib does not perform.
- Drive
permissions.createdefaults to sending a notification email - the lib explicitly disables this. Robert delivers the URL in the ray-update body, not via Google's mailer. - Tab names containing spaces work, but ranges must quote them:
'Retainer Balance'!A1- the lib's helpers handle this by passing the unquoted tab name to googleapis, which quotes internally.
Graduation
This skill is prose with a shape eval. Graduate by adding a script that wraps the common create-then-share-then-verify flow in one script - the business-tracking sheet is the first candidate.

OpenUI Resource
- Skill-owned OpenUI Lang resource:
state/skills/sheets/resources/ui.openui. Read it before rendering or editing this skill's generated component surface. - Treat this resource as a first-class artifact of the skill, not a generic chat response. Improve it when the skill's user-facing output needs to become richer.
- System resources compose OpenUI primitives and inherit SnappyChat tokens. Use
ui_contract: brandedin SKILL.md only for deliberate platform or client visuals.
Known Pitfalls
GOOGLE_SERVICE_ACCOUNT_KEYnewline format - bypassing the lib means OpenSSL throwsDECODER routines :: unsupportedwith no further detail- Tab names with spaces need range-quoting (
'Retainer Balance'!A1) when constructing ranges by hand; the lib'swriteRows/readRowshandle this for you writeRowsappends - to overwrite, you need a separatevalues.updatecall or to clear the range first; lib does not (yet) expose an overwrite helper
Self-Test
An agent reading this should correctly:
- [ ] Use the lib's
createSpreadsheetrather than callinggoogleapisdirectly - [ ] Default
shareSpreadsheettosendNotificationEmail: false - [ ] Use
readRowsfrom a fresh process as the audit step
Self-report
If this loader fell short, append a line:
echo "[$(date -u +%FT%TZ)] sheets: <what was missing>" >> state/log/loader-feedback.log
<!-- kernel-ok: historical attribution for the PID-loader pattern. -->
Self-correcting loader (PID feedback)
This is the rule that makes loaders learn. Ported from snappy-kernel, where it demonstrably worked: the snappy-dom-cartographer skill mapped Skool admin UI once, every later ship-agent inherited the full map for free.
Before you finish, do two things:
1. Fix gaps (P - proportional). MANDATORY. If this loader didn't cover your case - if you had to read another file, run an undocumented command, work around a wrong selector, or discover a quirk - you MUST attempt an Edit to this AGENTS.md before you log.
- Default action: edit this file. Surgical. Add the missing line, table
row, or code example where it belongs. No restructuring.
- Only
LOGGEDis allowed when: the fix needs >10 lines, spans multiple
files, or requires a structural rewrite. In that case the state/regen/drain.sh queue picks it up asynchronously.
- "I didn't have time" / "it's minor" / "the next agent will figure it out"
are NOT valid reasons. Minor gaps compound - that's the whole point of this loop.
- Concrete example of a valid P-fix: discover
agent-browser screenshot
takes path positionally not as --output <path>. One line in a table. Edit it in. Do not just log it.
- The goal: the next agent never has to leave the loader.
2. Log the result.
echo "[$(date -u +%FT%TZ)] sheets: <what was missing or fixed> [FIXED|LOGGED]" >> state/log/loader-feedback.log
FIXED= you patched this loader inline (P-fix).LOGGED= too large for inline; the PostToolUse enqueue + Stop-hook drain
will rewrite the loader from scratch on next session-end.
Do not skip this. Every agent run must leave the system better than it found it. The loader is the setpoint; you are the sensor; the gap is the error signal; closing the gap is the correction.
