doordash-allergy-shield

Apps & Automation

Persistent dietary safety layer for DoorDash CLI (dd-cli) ordering. Stores a personal/household dietary profile (allergens with severity tiers, diets, dislikes) that every cart is vetted against before checkout, with a deterministic tripwire — the vetting step saves the full cart contents to a vetted-cart dump, and a PreToolUse hook re-greps that dump against the anaphylaxis-severity allergen list before any checkout URL is allowed. Use when the user mentions allergies or dietary restrictions, when ordering food for someone with restrictions, or on every dd-cli cart flow while this skill is installed. A tripwire, not medical-grade — the human checkout page is the final check.

DoorDash Allergy Shield

Claude has no cross-session memory: tell it "I'm allergic to peanuts" today and tomorrow it happily adds pad thai. This skill persists a dietary profile and makes cart vetting mandatory — with a deterministic hook double-checking the highest-severity allergens before any checkout URL is emitted.

Unofficial community skill built on DoorDash's doordash-oss/doordash-cli.

Honest limits (state these to the user on first use)

Matching is heuristic, against item names/descriptions from cart show output plus a synonyms table. It cannot see full ingredient lists and knows nothing about cross-contamination in the kitchen.
It is a tripwire against agent mistakes, not a medical device. The DoorDash payment page — where the human reviews the real order — is the documented final check.
False positives are accepted by design: blocking a safe ponzu bowl is cheap; the reverse is not. Hook matching is substring-based (short allergen names like "oat" can match inside "goat cheese") — annoying, never dangerous.
The references/allergen-synonyms.md table is intentionally broader than the compact synonym subset hardcoded in the checkout-gate hooks; adding a synonym to the reference doc alone does not change what the hooks enforce.

Components in this bundle

Piece	Role
this skill	vetting protocol + profile management
`references/allergen-synonyms.md`	hidden-allergen lookup table
hook `doordash/doordash-allergy-checkout-gate`	deterministic re-check at checkout
command `/doordash-profile`	manage the dietary profile interactively

State

~/.claude/doordash-profile/dietary.json — the profile. Structure:

{
  "people": {
    "me": {
      "allergens": [
        { "name": "peanut", "severity": "anaphylaxis" },
        { "name": "shellfish", "severity": "avoid" }
      ],
      "diets": ["vegetarian"],
      "dislikes": ["cilantro"]
    },
    "sam": { "allergens": [{ "name": "egg", "severity": "avoid" }], "diets": [], "dislikes": [] }
  }
}

Severity tiers: anaphylaxis (hook-enforced, never overridable in-session), avoid (requires explicit human acknowledgment to keep the item), preference (mention it, don't gate on it).

~/.claude/doordash-profile/vetted/<cart-uuid>.json — one dump per vetted cart: the full raw cart show output plus your verdict and a timestamp. The checkout hook greps this artifact — it trusts the dump, not your claim.

Protocol

Session start

Read dietary.json. Missing → offer to create it interactively (or via /doordash-profile). If the user is ordering for others ("lunch for me and Sam"), make sure each eater exists in the profile or ask for their restrictions.

After EVERY cart mutation (add-items / remove-item / reorder)

Run dd-cli cart show --cart-uuid <X> and capture the full output.
Check every line against each relevant eater's profile — direct matches AND hidden sources from references/allergen-synonyms.md (satay→peanut, aioli→egg, ponzu→soy+fish, …).
On a conflict:
- anaphylaxis → remove the item (dd-cli cart remove-item) and tell the user why. Do not offer to keep it.
- avoid → present the conflict; keep only with explicit acknowledgment.
- preference → mention it in passing.
Items whose name is too opaque to judge ("Chef's Special #3") → mark UNVERIFIED and require the user's explicit sign-off for eaters with anaphylaxis entries.
Write the vetted dump: full cart show output + verdict + ISO timestamp to ~/.claude/doordash-profile/vetted/<cart-uuid>.json. Without this file the checkout hook blocks — vetting is not optional.

At checkout

Just run dd-cli order checkout-url --cart-uuid <X> (or the dd-guard wrapper when doordash-spend-guard is installed — the two gates compose). The hook independently verifies: dump exists, is newer than the last cart mutation it saw, and contains no anaphylaxis-tier keyword. If it blocks, do NOT try to work around it — fix the cart, re-vet, and explain to the user what tripped.

Rules

Never edit dietary.json from the shell; profile changes go through /doordash-profile (interactive, confirmed).
Never write a vetted dump without actually running cart show fresh — the dump IS the audit artifact.
When in doubt about an ingredient, doubt is a conflict.
