File contents

GTD Capture

Fast append to inbox. No priority, no routing — just capture.

Steps

Take $ARGUMENTS as item text.
Clean URLs — if the item contains a URL, strip tracking params (see below).
Read /praxis/gtd/01-inbox.md. If missing → error (see below).
Find the ### New section. If missing → error.
Insert with Edit, newest-first (after the header, before existing items):
- old_string: ### New
- new_string: ### New\n- [ ] <cleaned item> [created:: TODAY]
- TODAY = today's date as YYYY-MM-DD.
Report: Captured: <item>.

Example — capture "buy milk" on 2026-05-23:

### New
- [ ] buy milk [created:: 2026-05-23]
- [ ] existing item [created:: 2026-05-20]

URL Cleaning

If the item contains a URL, strip these query params (case-insensitive key):

Group	Params
Analytics	`utm_*` (any `utm_`-prefixed key)
Ad/click IDs	`fbclid` `gclid` `gbraid` `wbraid` `msclkid` `dclid` `yclid` `twclid` `ttclid`
Email/marketing	`mc_eid` `mc_cid` `_hsenc` `_hsmi` `vero_id` `vero_conv` `oly_anon_id` `oly_enc_id` `mkt_tok`
Social/referral	`igshid` `ref` `ref_src` `ref_url` `source` `spm`
Platform	`si` (YouTube/Spotify share token) `feature` (YouTube)

Rules: remove only listed keys; keep all other params (id q v page t, etc.); drop a trailing ? if no params remain; preserve path + #fragment; leave non-URL text untouched.

Triggers

Direct: /gtd:capture buy milk · /gtd:capture call John about project
Natural language: "add buy milk to inbox" · "capture: need to call John" · "inbox: review quarterly goals"

Notes

Append as-is — no flags, no parsing, no priority sorting (that's triage).
Empty ### New is fine. Preserve all other sections unchanged.

Errors

File not found → report, suggest checking vault path.
### New missing → report, suggest running setup.
Edit fails (concurrent modification) → report, ask user to retry.
