stream-feeds-migration

stream-feeds-migration is a skill for Claude Code, Codex from GetStream/agent-skills. It costs 150 tokens per session (3,212 once invoked), scanned A, original, Apache-2.0.

A migration helper for Stream Activity Feeds, a service for storing and displaying social activity such as posts and reactions. It creates a mapping from version 2 data to version 3 by sampling the app's real version 2 activities and reactions.

In plain words
What is it for?
Use it to prepare, review, or debug the mapping needed to move an Activity Feeds app from version 2 to version 3.
Why use it?
It bases the migration mapping on the data the app actually contains, reducing the risk of incorrect synchronisation or bulk-export configuration.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

stream-feeds-migration 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 5d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/fetch_sample.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 279 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Stream Feeds - v2 to v3 sync mapping

Read first (every session): Glob ../stream/SKILL.md and Read ../stream/RULES.md (both ship with this skill). The Secrets rule governs every step below: the app secret never enters the conversation. RULES.md also carries the Peer skills procedure for installing and invoking any other pack skill on demand.

Produce the mapping object for an app's v2 -> v3 sync configuration by looking at what the app's v2 data actually contains, rather than at what anyone believes it contains.

One mapping serves both migration paths - the live syncer and the bulk exporter read the same configuration. Getting it right once fixes both; getting it wrong breaks both in the same way.


Workflow

1. Get credentials into the environment

You need the v2 app's API key and secret. The secret signs an HS256 JWT locally, stamped with iat/exp so it expires five minutes after it is minted. The secret itself is never written to the sample file, never echoed back, and never sent anywhere except as that signature.

Per ../stream/RULES.md > Secrets, do not ask the user to paste the secret into the chat, and never cat, grep, or Read a .env file to find it. Ask them to export it themselves so it stays out of the transcript:

! export STREAM_API_KEY=<v2 app key> STREAM_API_SECRET=<v2 app secret>

The ! prefix runs the command in the user's own session, so the value lands in the environment without passing through the conversation. Confirm it took with a presence check that never prints the value:

test -n "$STREAM_API_SECRET" && echo SECRET_SET || echo SECRET_MISSING

Do not proceed without a real key and secret. There is no useful analysis to do against a made-up app, and a wrong secret only produces a 403.

2. Pick the target

Default to production - https://api.stream-io-api.com. Use it unless the user names a different environment (EU, dedicated, staging), in which case pass --base-url <that URL>.

Changes

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.
