Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00138 | $0.01070 |
| Opus 5.5 | $0.00055 | $0.00428 |
| Sonnet 5.5 | $0.00028 | $0.00214 |
| Haiku 4.5 | $0.00014 | $0.00107 |
Grade A, and why
firebase-firestore scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 17d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
92% identical to firebase-firestore — 24 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Cloud Firestore Database and Operations
[!IMPORTANT] Security Rules Authoring (
firestore.rules) Whenever your task requires creating, authoring, or modifyingfirestore.rules:
- If subagent delegation AND the
firestore-rules-authorsubagent are available: delegate authoringfirestore.rulesto thefirestore-rules-authorsubagent rather than writingfirestore.rulesdirectly in the main agent.- If subagent delegation is unavailable (e.g., subagents not enabled in the IDE) OR
firestore-rules-authoris not installed: read and follow thefirestore-rules-creationskill to writefirestore.rulesdirectly.
Before setting up dependencies, writing data models, or configuring security rules, you MUST always identify the Firestore instance edition.
1. Instance Selection and Edition Detection
Run the following command to list current Firestore databases:
npx -y firebase-tools@latest firestore:databases:list
A. Instance Found
-
For each database found, inspect its edition and details:
npx -y firebase-tools@latest firestore:databases:get <database-id> -
Ask the user which database instance they wish to target or if they would prefer to create a new instance.
-
Once the target instance is established:
- If the
editionisSTANDARD, follow the guides underreferences/standard/. - If the
editionisENTERPRISEor native mode, follow the guides underreferences/enterprise/.
- If the
B. No Instance Found (or New Requested)
If no databases exist or the user requests a new one, default to provisioning an
Enterprise edition database and ask the user what location to use. Run
npx -y firebase-tools@latest firestore:locations to get the list of options.
Suggest colocating with other resources if applicable.
Once the location is determined, create the database:
npx -y firebase-tools@latest firestore:databases:create <database-id> --edition="enterprise" --location="<selected-location>"

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

firebase-firestore is a skill published in the GitHub repository pleaseai/claude-code-plugins (16 stars, last pushed 5d ago), licensed MIT. It adds 138 tokens to every session and 1,070 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 92% identical to firebase-firestore, differing in 24 lines, and is treated as a copy.
