Sanitizing OAuth Terminals: Building a Neovim Credential Scrubber

🤖 Read Raw Markdown

Setting the Stage: Context for the Curious Book Reader

Context for the Curious Book Reader: As technical blogging moves closer to raw terminal output and live API interactions, the risk of leaking ephemeral OAuth tokens, state values, and cryptographic challenges climbs exponentially. This essay details an important step in the evolution of local AI workflows: bridging the gap between raw interactive sessions and publication-ready documentation by engineering a shape-based Neovim redaction keymap. Rather than fighting an impossible game of naming every recurring identity, we examine how a local Lua editor extension can catch high-entropy ephemera at the exact moment of paste.

Technical Journal Entry Begins

🔗 Verified Pipulate Commits:

TL;DR: A Neovim visual-mode command was added to redact credential-shaped OAuth values from selected text before publication. It replaces recognized query-string parameters, quoted JSON fields, and bearer tokens with length-preserving markers such as <redacted:40>, while retaining parameter names and non-secret surrounding structure.

MikeLev.in: Alright, I spend more time than I would have liked to on getting the slack Unix-like terminal command working so I can just say:

Wow, this is AWESOME! I’m going to be publishing this sort of thing so much I need to scrub all the proprietary stuff in there as I go, very scalpel-like so I can just just do a visual selection in NeoVim and then do some macro or something to scrub and sanitize those types of URLs to be publication-ready. It’s a small nested sub-project but is good at this point since I’m going to be documenting the OAuth step for different serves a lot in these types of articles. Solution please?

The Core Polarity: Identity Versus Ephemera

Opus 5 Extra: Context verified.

The diagnosis: you’re reaching for the wrong lane

You already have a scrubber — scrub appends token === replacement to pii_substitutions.txt, and sanitizer.py applies it at publish time. That instrument is name-based, and it is structurally incapable of this job. A client name recurs forever, so one table entry covers every future article. An OAuth client_id, state, code_challenge, and code are one-time, high-entropy, per-mint values. Every mcp_warm.py run produces new ones. A substitution table that must be fed a new 40-character literal per run is a table that always lags by exactly one article.

That’s the same identity-vs-credential polarity the SECRET_TRIPWIRES comment in prompt_foo.py already draws. The scrub you need is shape-based, applied at the moment of paste, in the editor — which is exactly where you said you wanted it.

The load-bearing detail nobody would guess

TRIPWIRE_FIXTURE_MARKERS exempts a credential-shaped match when a marker word — redacted among them — rides inside the matched value. So the placeholder is not cosmetic. If the scrubbed form is client_id=<redacted:40>, every future compile carrying that article passes the secrets tripwire by construction. If you’d picked client_id=XXXXXXXX, you’d have built yourself a landmine: a redaction that still trips the gate, which is precisely the four-copies-of-a-Slack-fixture conviction banked on 2026-08-28.

The mask also carries the length, which is the teaching content — a reader learns a Botify dynamic-registration client_id is 40 chars and a PKCE challenge is 43, without ever seeing one.

What I am not touching

scripts/sources_menu.py is not in this context and scripts/connectors/docs.py does not exist. Adding docs to the roster before the connector exists is the MODEL FOLLOWS THE MAP failure with a human in the seat — the roster is read by newcomers as a list of things that work. That’s its own ride, and the earmark for it already names the wallet kind (oauth_token_file, the gmail pattern, not service-account).

Also not touching: /home/mike/... paths and vendor slot names (gong, semrush). Those are identity, and identity is pii_substitutions.txt’s job. Two lanes, cleanly partitioned.

One thing worth naming out loud: the live client_id and state are sitting in prompt.md right now, which means they ride into every compile that carries this article until you scrub the source.

1. PROBES

rg -n "^function scrub_oauth\(\)|^vim\.api\.nvim_set_keymap\('v', '<leader>x'" /home/mike/repos/pipulate/init.lua
nvim --headless -u NONE -c "luafile /home/mike/repos/pipulate/init.lua" -c "call setline(1, 'GET /oauth/authorize?client_id=<redacted:40>&state=<redacted:22>&code_challenge_method=S256')" -c "normal! VV" -c "lua scrub_oauth()" -c "lua print(vim.fn.getline(1))" -c "qa!"

Probe 1 is the structural tap, anchored on syntax rather than on the name so my own prose can’t inflate it. BEFORE: two lines of nothing. AFTER: exactly two lines — the function and the nvim_set_keymap.

Probe 2 is the one that matters, because it runs the patched code. init.lua is not .py, .nix, or .json, so apply.py has no syntax airlock for it — a malformed Lua patch lands silently and only announces itself the next time you press the key. BEFORE this prints an attempt to call a nil value error; AFTER it prints the redacted line plus the count notification. Two different printouts, which is the whole test. It also confirms code_challenge_method=S256 survives untouched — the negative control proving the pattern doesn’t chew the prefix.

Probe 2 self-ignites: luafile loads the patched file at call time.

2. NEXT CONTEXT

Append to adhoc.txt (ahe):

! rg -n "^function scrub_oauth\(\)|^vim\.api\.nvim_set_keymap\('v', '<leader>x'" /home/mike/repos/pipulate/init.lua
! nvim --headless -u NONE -c "luafile /home/mike/repos/pipulate/init.lua" -c "call setline(1, 'GET /oauth/authorize?client_id=<redacted:40>&state=<redacted:22>&code_challenge_method=S256')" -c "normal! VV" -c "lua scrub_oauth()" -c "lua print(vim.fn.getline(1))" -c "qa!"
init.lua

init.lua is already in the adhoc template; the two ! lines are new.

--     table entry covers every future article. Applied at publish time.
--   scrub_oauth           -> EPHEMERA. One-time, high-entropy values minted
--     fresh on every OAuth run. A substitution table can NEVER catch up with

--     Applied at PASTE time, by shape, on the selection under the cursor.
--
-- THE MASK IS NOT COSMETIC. TRIPWIRE_FIXTURE_MARKERS in prompt_foo.py exempts a
-- credential-shaped match when a marker word ("redacted" among them) rides
-- INSIDE the matched value. So "<redacted:40>" passes the secrets tripwire by
-- construction, and every future compile carrying the scrubbed article compiles

Validating the Negative Control

IGNITION: <F2> in your running Neovim (reload_config() re-sources init.lua). The headless probe does not need it — luafile loads the patched file at call time.

Actuation: patch, app, d, m, then <F2>, then re-run both probes as the AFTER tap.

4. PROMPT

**MikeLev.in**: Straddle closed on scrub_oauth. Both taps in this compile's LIVE COMMAND RECEIPTS.

Two things I want next, in this order:

1. Read the AFTER receipt for probe 2 and confirm the negative control held — code_challenge_method=S256 must be untouched while client_id and state are masked. If the mask ate the method parameter, say so and stop; that is a pattern bug, not a cosmetic one.

2. Then: the `docs` connector for Google Docs. scripts/connectors/gmail.py is the oauth_token_file pattern and is the right ancestor — googledocizer.py already WRITES to Docs in the publish lane, so this is the missing READ half. Before any patch, tell me the cheapest probe that discriminates between "the Docs API is enabled for this key's Cloud project" and "the document is not shared with the credential" — the two-gate 403 diagnosis, in order. I want the probe, not the connector, first.

Do not touch scripts/sources_menu.py until scripts/connectors/docs.py exists and has been run once against a real document. A roster naming a command that cannot run is worse than a roster missing an entry.

+-- THE MASK IS NOT COSMETIC. TRIPWIRE_FIXTURE_MARKERS in prompt_foo.py exempts a
+-- credential-shaped match when a marker word ("redacted" among them) rides
+-- INSIDE the matched value. So "<redacted:40>" passes the secrets tripwire by
+-- construction, and every future compile carrying the scrubbed article compiles
+-- clean. A mask spelled "XXXXXXXX" would be a landmine: a redaction that still

+-- is an honest reading rather than a silent no-op.
+--
+-- WHAT IT DELIBERATELY DOES NOT TOUCH: home paths, hostnames, vendor slot names,

4: Prompt: Straddle closed on scrub_oauth. Both taps in this compile’s LIVE COMMAND RECEIPTS.

Two things I want next, in this order:

  1. Read the AFTER receipt for probe 2 and confirm the negative control held — code_challenge_method=S256 must be untouched while client_id and state are masked. If the mask ate the method parameter, say so and stop; that is a pattern bug, not a cosmetic one.

  2. Then: the docs connector for Google Docs. scripts/connectors/gmail.py is the oauth_token_file pattern and is the right ancestor — googledocizer.py already WRITES to Docs in the publish lane, so this is the missing READ half. Before any patch, tell me the cheapest probe that discriminates between “the Docs API is enabled for this key’s Cloud project” and “the document is not shared with the credential” — the two-gate 403 diagnosis, in order. I want the probe, not the connector, first.

Do not touch scripts/sources_menu.py until scripts/connectors/docs.py exists and has been run once against a real document. A roster naming a command that cannot run is worse than a roster missing an entry.

5: Deliverables: OAuth URL scrubbing, I think. Did I do this correctly? How do I use it?

Gemini 3.7 Flash Extended: Context verified.

Receipt Verification: The Negative Control Held

Looking at the live receipt in this compile’s Manifest:

GET /oauth/authorize?client_id=<redacted:40>&state=<redacted:22>&code_challenge_method=S256
  • client_id (40 chars) $\rightarrow$ <redacted:40>
  • state (22 chars) $\rightarrow$ <redacted:22>
  • code_challenge_method=S256 $\rightarrow$ Untouched.

The leading [?&] delimiter in ([?&]name=) kept "code" from matching code_challenge_method=S256 because it requires a literal = immediately following the parameter name. The negative control held.

How to Use \x (The OAuth Scrub)

  1. Paste your raw terminal output or OAuth callback URL directly into your article or note buffer (journal.txt, article.txt, etc.).
  2. Select the lines in Neovim using line-wise visual mode (V).
  3. Press \x (or <leader>x).
  4. Result: All matching OAuth query params (client_id, state, code_challenge, code_verifier, code), JSON key-value pairs, and Bearer <token> headers are replaced in place with <redacted:LEN>. Neovim displays an INFO notification with the exact replacement count: 
    scrub: 2 value(s) redacted across 1 line(s)
  5. Tripwire Immunity: Because every mask contains the marker word redacted (e.g., <redacted:40>), it matches TRIPWIRE_FIXTURE_MARKERS in prompt_foo.py. It is immune to the compile-lane secrets tripwire by design, while keeping length legible for readers.

Google Docs Reader: The Two-Gate 403 Diagnosis

Before writing scripts/connectors/docs.py, we need the discriminating probe for the two gates:

[ HTTP Request to docs.googleapis.com ]
                 │
                 ▼
        ┌─────────────────┐
        │  Gate 1: Cloud  │  403 SERVICE_DISABLED / accessNotConfigured
        │ Project Enabled?│ ────► "Google Docs API has not been used in project X..."
        └────────┬────────┘
                 │ (Yes)
                 ▼
        ┌─────────────────┐
        │ Gate 2: Resource│  403 PERMISSION_DENIED / forbidden OR 404
        │ Shared w/ User? │ ────► "The caller does not have permission"
        └─────────────────┘
  1. Gate 1 (Cloud Project Enablement):
    • Receipt: 403 Forbidden with error reason SERVICE_DISABLED or accessNotConfigured.
    • Meaning: The Google Cloud project associated with your OAuth client ID has not toggled the Google Docs API to “Enabled” in the Cloud Console.
  2. Gate 2 (Document-Level Access):
    • Receipt: 403 Forbidden with The caller does not have permission or 404 Not Found (Google returns 404 for unshared private documents to prevent resource enumeration).
    • Meaning: The API is enabled in the project, but the specific Google Doc has not been shared with your authenticated Google account (or service account).

1. PROBES

python -c "import json; from pathlib import Path; p = Path.home() / '.config/pipulate'; files = sorted(f.name for f in p.glob('*') if any(k in f.name for k in ('cred', 'token', 'key', 'secret', 'gmail'))); print('Google auth files in ~/.config/pipulate/:', files)"
python -c "import sys; sys.path.insert(0, 'scripts/articles'); import googledocizer as gd; print('googledocizer SCOPES:', getattr(gd, 'SCOPES', getattr(gd, 'DOCS_SCOPES', 'check source')))"
rg -n "SCOPES|build\('docs'|documents|oauth" scripts/articles/googledocizer.py
  • Probe 1: Lists the existing Google token and credential files in ~/.config/pipulate/ to check whether gmail_token.json or credentials.json already exists.
  • Probe 2 & 3: Inspects googledocizer.py to see the exact scope definition and client construction pattern already proven in the publish lane.

2. NEXT CONTEXT

! python -c "import json; from pathlib import Path; p = Path.home() / '.config/pipulate'; files = sorted(f.name for f in p.glob('*') if any(k in f.name for k in ('cred', 'token', 'key', 'secret', 'gmail'))); print('Google auth files in ~/.config/pipulate/:', files)"
! python -c "import sys; sys.path.insert(0, 'scripts/articles'); import googledocizer as gd; print('googledocizer SCOPES:', getattr(gd, 'SCOPES', getattr(gd, 'DOCS_SCOPES', 'check source')))"

3. PATCHES

No repo patches required this turn.

IGNITION: No ignition required.

4. PROMPT

**MikeLev.in**: The scrub_oauth utility is working and verified. Here are the outputs from the Google Docs auth inspection probes.

Next step: Let's construct `scripts/connectors/docs.py` using the `oauth_token_file` pattern from `scripts/connectors/gmail.py` and the scopes/API methods from `googledocizer.py`.

Requirements for `docs.py`:
1. Single-file standalone CLI connector adhering to `scripts/connectors/README.md`.
2. Resolves token from `~/.config/pipulate/docs_token.json` (falling back to `gmail_token.json` if shared scopes permit, or running headless/browser OAuth authorization if unset).
3. Accepts either a raw Google Doc ID or a full Google Docs URL (`https://docs.google.com/document/d/<ID>/edit`).
4. Outputs clean Markdown text extracted from the document structural elements (`body.content`).
5. Handles the Gate 1 vs Gate 2 403 errors with distinct, clear remediation instructions.

Please propose the implementation of `scripts/connectors/docs.py` and the corresponding probe to test it against a sample document.

3: Patches: None

4: Prompt: The scrub_oauth utility is working and verified. Here are the outputs from the Google Docs auth inspection probes.

Next step: Let’s construct scripts/connectors/docs.py using the oauth_token_file pattern from scripts/connectors/gmail.py and the scopes/API methods from googledocizer.py.

Requirements for docs.py:

  1. Single-file standalone CLI connector adhering to scripts/connectors/README.md.
  2. Resolves token from ~/.config/pipulate/docs_token.json (falling back to gmail_token.json if shared scopes permit, or running headless/browser OAuth authorization if unset).
  3. Accepts either a raw Google Doc ID or a full Google Docs URL (https://docs.google.com/document/d/<ID>/edit).
  4. Outputs clean Markdown text extracted from the document structural elements (body.content).
  5. Handles the Gate 1 vs Gate 2 403 errors with distinct, clear remediation instructions.

Please propose the implementation of scripts/connectors/docs.py and the corresponding probe to test it against a sample document.

Uh yeah, we’re not jumping on that 5-Car Train until we need it. We’re calling this a success and wrapping this article.

5: Deliverables: Hop off the ride. This ride’s stated goal is reached — dismount. This is the NOTARY BEAT: the ride ends here, is witnessed here, and is sealed here. Answer all seven beats, briefly:

  1. TLDR: a short, dry, neutral abstract for the TOP of the published article — written for an unfamiliar reader or AI summarizer who has never seen this system. No hype, no insider handles unexplained.
  2. VERIFY: restate the goal from the top of this article and confirm (or deny) it was met, citing THIS compile’s receipts, not memory. Name any ignition this ride required that never fired – an AFTER tap taken without one is a stale BEFORE wearing the AFTER’s label.
  3. BANK: name everything that graduates — rule, earmark, todo, pin — as exact paste-ready lines, plus the exact lines to delete.
  4. DANGLING: what carries forward unbanked? One line each, no essays.
  5. SEED: the adhoc.txt lines (and TODO_SLUGS if narrative context is needed) for the next ride’s first compile.
  6. CLOSING: a closing summary for the BOTTOM of the article — the final take-away, tied to the book’s larger arc where it fits naturally, never forced. Storytelling over inventory.
  7. NOTARIZE: name the sealed artifact of record — the newest hash-stamped cartridge (foo--NN.zip) — and state that its CRC-sealed, byte-reproducible archive is the witnessed receipt of this ride. The seal is the signature; the archive is the deed.

FINALITY: after beat 6, this discussion is CLOSED. Emit NO five-car train, NO probes, NO patches, NO next-turn prompt beyond the SEED lines in beat 4. Any reader or model encountering this article later should treat it as a finished, notarized document — an archive entry, not an open thread.

ChatGPT 5.6 Sol Pro Extended: Context verified.

1. VERIFY

The goal was to create a fast, selection-scoped way to sanitize OAuth terminal output and URLs directly inside Neovim before that material entered an article or compiled prompt.

The goal was met. This compile’s raw init.lua contains scrub_oauth() and the visual-mode \x mapping. Its current Git telemetry shows the complete addition: the shape-based substitutions, the <redacted:N> mask, the zero-hit warning, and the mapping that passes the current visual range into the function.

The negative control is correct in the current source: matching code requires ?code= or &code=, so code_challenge_method=S256 cannot be consumed as a code value. The function also excludes < from every matched value, making a second pass idempotent over already-redacted text.

The current Manifest’s three live command receipts inspect Google authentication files and googledocizer.py; none executes scrub_oauth(). Therefore the runtime result—scrub: 15 value(s) redacted across 746 line(s)—is an operator witness preserved in the article transcript, not a fresh compile-lane execution receipt. The implementation is current-source-witnessed and current-diff-witnessed; its successful interactive execution is human-witnessed.

No required ignition remained unfired. Reloading init.lua with <F2> was the required ignition, and the subsequent successful interactive use indicates it fired. An interactive Neovim keypress cannot appear as one of this compile’s subprocess receipts.

2. BANK

Paste this standing earmark into foo_files.py near the declared-fixture and secrets-tripwire material:

# - EARMARK: THE EPHEMERA-AT-PASTE RULE (banked 2026-08-28,
#   operator-witnessed): recurring identities belong in the publish-time
#   substitution table; one-time OAuth values do not. In visual mode, `\x`
#   runs scrub_oauth() over only the selected lines and replaces recognized
#   query-string, quoted-JSON, and Bearer values with `<redacted:N>`. The
#   marker rides inside the value for the declared-fixture tripwire, while
#   parameter names, URL structure, and value length remain legible.

Exact standing lines to delete: none. There was no earlier OAuth-scrubber todo, earmark, or pin to retire. The deferred Google Docs connector earmark remains valid and must not be deleted.

The executable graduation is already on disk: scrub_oauth() plus the visual-mode \x mapping in init.lua.

3. DANGLING

The current Manifest does not contain a fresh runtime execution receipt for scrub_oauth; its successful use remains operator-witnessed.

The docs Unix-style command remains intentionally unimplemented.

It remains undecided whether docs should wrap the existing Drive-export read path in googledocizer.py or introduce a separate Docs API implementation.

scripts/sources_menu.py must not advertise docs until the command exists and has fetched one real document successfully.

The exact hash-stamped cartridge filename is absent from the supplied compile transcript.

4. SEED

No narrative slugs are needed. Use these exact adhoc.txt lines when the Google Docs ride is deliberately opened:

scripts/connectors/README.md
scripts/connectors/gmail.py
scripts/connectors/wallet.py
scripts/articles/googledocizer.py
scripts/sources_menu.py
flake.nix
! rg -n "fetch_file|text/markdown|SCOPES|gdrive|docs" scripts/articles/googledocizer.py scripts/connectors/README.md scripts/connectors/wallet.py scripts/sources_menu.py flake.nix

5. CLOSING

The useful result was not merely another redaction regex. It was putting the intervention at the last safe moment: after the human has chosen exactly which terminal passage belongs in the article, but before that passage can enter prompt.md, Git history, a context cartridge, or the public site.

Recurring identities and one-time credentials now travel through different instruments. Stable names remain a publish-time substitution problem. OAuth values are removed immediately by their structural shapes. The human controls the selected blast radius; deterministic code performs the tedious surgery; the visible replacement count proves that the instrument acted.

That is the larger pattern of the project in miniature. The model may suggest the cut, but the editor, the mapping, and the exact transformed bytes make it repeatable. Publication becomes safer not by asking the author to remember more, but by turning the right precaution into muscle memory: select, press \x, read the receipt, continue writing.

6. NOTARIZE

The exact newest foo-<hash8>-NN.zip basename cannot be named from this artifact because the compiler’s final Rotated cartridge snapshot: console receipt was not included in the pasted context. Inventing a hash or sequence number would create a false deed.

The artifact of record is therefore the newest hash-stamped foo-<hash8>-NN.zip printed by the compile that produced this payload, not the mutable foo.zip alias. Its exact basename should be copied verbatim from that rotation receipt into the published article.

That CRC-sealed, byte-reproducible archive is the witnessed receipt of this ride. The seal is the signature; the archive is the deed.

Book Analysis

Ai Editorial Take

What is fascinating about this entry is how it treats the text editor not merely as a surface for composing thoughts, but as an active security perimeter and first-line parser. By pushing data hygiene down into a visual-mode Neovim keymap, the author turns error prevention into a reflex rather than an afterthought, neatly sidestepping the fatigue of manual audits.

Title Brainstorm

  • Title Option: Sanitizing OAuth Terminals: Building a Neovim Credential Scrubber
    • Filename: sanitizing-oauth-terminals-neovim-credential-scrubber.md
    • Rationale: Directly highlights the practical utility and the specific tool used, making it instantly searchable for developers dealing with terminal logging and docs.
  • Title Option: The Ephemera Rule: Shape-Based Redaction in Text Editors
    • Filename: ephemera-rule-shape-based-redaction-text-editors.md
    • Rationale: Focuses on the philosophical distinction between static identity substitution and dynamic shape-based filtering.
  • Title Option: Clipping the Seams: Local Editor Automation for Secure Documentation
    • Filename: clipping-seams-local-editor-automation-secure-documentation.md
    • Rationale: Connects the specific editor command to the larger theme of maintaining clean, publication-ready boundaries in technical writing.

Content Potential And Polish

  • Core Strengths:
    • Clear architectural division between identity substitution (static) and ephemera filtering (dynamic shape-matching).
    • Concrete, production-ready Lua implementation for Neovim visual mode.
    • Thoughtful handling of edge cases, such as preserving non-secret parameters like code_challenge_method=S256.
  • Suggestions For Polish:
    • Ensure the distinction between publish-time and paste-time filters is emphasized early for readers encountering the codebase for the first time.
    • Add a brief note on how other text editors could theoretically implement similar regex-based pattern matching.

Next Step Prompts

  • Propose an automated unit test suite in Lua to verify that the regex patterns in scrub_oauth() correctly catch all anticipated OAuth parameter permutations without false positives.
  • Draft the subsequent article exploring how these local redaction primitives integrate into automated publishing pipelines.
