porteden sheets-logger
Append log entries to a Google Sheet with porteden sheets. This skill configures a target log spreadsheet via environment variable so agents can record events, activity logs, and audit trails without repeating the file ID. Use -jc flags for AI-optimized output.
If porteden is not installed: brew install porteden/tap/porteden (or go install github.com/porteden/cli/cmd/porteden@latest).
Setup
1. Authenticate (once)
- Browser login (recommended):
porteden auth login— opens browser, credentials stored in system keyring - Direct token:
porteden auth login --token <key>— stored in system keyring - Verify:
porteden auth status - If
PE_API_KEYis set in the environment, the CLI uses it automatically (no login needed). - Drive access requires a token with
driveAccessEnabled: trueand a connected Google account with Drive scopes.
2. Set the target log sheet (one-time)
If PE_SHEET_ID is already set, skip to step 3 — the target sheet is configured.
If PE_SHEET_ID is not set, find the spreadsheet by name:
porteden drive files -q "Activity Log" --mime-type application/vnd.google-apps.spreadsheet -jcCopy the id field from the result (already provider-prefixed, e.g., google:1BxiMVs0XRA5...) and set it:
export PE_SHEET_ID="google:1BxiMVs0XRA5nFMdKvBdBZjgmU..."To persist across sessions, add to your shell profile (~/.bashrc, ~/.zshrc) or .env file. Once set, this step does not need to be repeated.
3. Test the connection (one-time)
porteden sheets info $PE_SHEET_ID -jcExpected: returns spreadsheet title, sheet tabs, and dimensions. If this fails, verify the file ID and that your token has Drive access. Once verified, skip this step in future runs.
4. Read the header row (one-time)
Before logging, confirm the column layout of the target sheet:
porteden sheets read $PE_SHEET_ID --range "Sheet1!1:1" -jcMatch your log entries to this column order. Once you know the schema, skip this step in future runs.
Logging data
Append a log entry
Append adds rows after the last row with data. Existing log entries are never overwritten.
- Single log entry:
bash porteden sheets append $PE_SHEET_ID --range "Sheet1!A:E" --values '[["2025-01-15T09:30:00Z","deploy","production","v2.4.1 released","success"]]'
- Multiple log entries (batch):
bash porteden sheets append $PE_SHEET_ID --range "Sheet1!A:E" --values '[["2025-01-15T09:30:00Z","deploy","production","v2.4.1 released","success"],["2025-01-15T09:31:12Z","healthcheck","production","all endpoints healthy","success"]]'
- Log entry from CSV string:
bash porteden sheets append $PE_SHEET_ID --range "Sheet1!A:E" --csv "2025-01-15T09:30:00Z,deploy,production,v2.4.1 released,success"
- Bulk log import from CSV file:
bash porteden sheets append $PE_SHEET_ID --range "Sheet1!A:E" --csv-file ./events.csv
Verify logged entries
Read back recent rows to confirm the log was recorded:
porteden sheets read $PE_SHEET_ID --range "Sheet1" -jcLog schema examples
Structure your log sheet with a header row. Common schemas:
Event log: Timestamp | Event | Source | Details | Status
Audit trail: Timestamp | Actor | Action | Resource | Before | After
Error log: Timestamp | Severity | Service | Message | Stack
Task log: Timestamp | Task | Agent | Input | Output | Duration
Best practices
1. Always use append — logging is append-only by nature. Never use write to overwrite log entries. 2. Include a timestamp in every entry — use ISO 8601 format (2025-01-15T09:30:00Z) for sortability and consistency. 3. Use --raw for literal values — prevents unintended formula evaluation (e.g., log messages starting with =). 4. Batch entries when possible — send multiple rows in one --values array rather than one-row-at-a-time to reduce API calls. 5. Specify column range in append (e.g., A:E not just A) — ensures data lands in the correct columns. 6. Read the header row first — confirm column order with porteden sheets read $PE_SHEET_ID --range "Sheet1!1:1" -jc before appending. 7. Use -jc on read/info — compact JSON output minimizes tokens for AI agents.
Range format
- Open-ended columns (for append):
Sheet1!A:E - Specific cells:
Sheet1!A1:E10 - Whole sheet:
Sheet1 - Header row only:
Sheet1!1:1
Notes
- Credentials persist in the system keyring after login. No repeated auth needed.
- Set
PE_PROFILE=workto avoid repeating--profile. -jcis shorthand for--json --compact: strips noise, limits fields, reduces tokens for AI agents.- File IDs are always provider-prefixed (e.g.,
google:1BxiMVs0XRA5...). Pass them as-is. --values,--csv, and--csv-fileare mutually exclusive — provide exactly one.--csvinline: use\nas row separator (e.g.,"ts,event,src\nts2,event2,src2").--rawflag disables formula evaluation (values written literally, not parsed as formulas).accessInfoin responses describes active token restrictions.- Environment variables:
PE_API_KEY,PE_PROFILE,PE_SHEET_ID,PE_FORMAT,PE_COLOR,PE_VERBOSE.
The capability, in one paragraph
Spreadsheets are still the analytic surface most non-engineering teams trust. Operations leads pivot on logged events, accountants reconcile rows, compliance teams export to PDF. Logger gives the agent a writable row-store that those audiences already own — without provisioning a database.
A few flags, predictable output
Bound to one sheet via PE_SHEET_ID
PE_SHEET_ID accepts the google: prefixed file ID. Every append targets that sheet — the skill cannot write elsewhere unless the env var is rotated. Misconfiguration fails closed.
export PE_SHEET_ID="google:1AbCdEf..." porteden sheets info $PE_SHEET_ID -jc porteden sheets read $PE_SHEET_ID --range "Sheet1!1:1" -jc Append-only writes
append finds the last non-empty row and writes after it (Google Sheets API insertDataOption=INSERT_ROWS). Existing rows are never overwritten — the sheet functions as a chronological event log.
Batch and CSV modes
--values takes a JSON array of arrays for batch appends; --csv-file ./events.csv parses CSV server-side. Use batch for in-process buffering; use CSV for nightly back-fills from an external source.
Five minutes, three commands
Install the PortEden CLI
OpenClaw skills delegate every API call to the porteden binary. Install once with Homebrew or Go.
brew install porteden/tap/porteden # orgo install github.com/porteden/cli/cmd/porteden@latest Authenticate
Browser-based login is recommended — credentials are written to your OS keyring. Token-based login is available for headless environments.
porteden auth login # headless / CIporteden auth login --token <PE_API_KEY> porteden auth status Install the logger skill
OpenClaw fetches the signed skill bundle and registers its commands with the agent.
