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 | $0.00000 | $0.00143 |
| Opus 5 | $0.00000 | $0.00072 |
| Sonnet 5 | $0.00000 | $0.00029 |
| Haiku 4.5 | $0.00000 | $0.00014 |
Grade A, and why
change-app-id 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 8d 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.
What it actually says
change-app-id
If the new application ID was not passed as an argument, ask:
"What is the new application ID? Use reverse-domain notation, e.g. com.company.appname"
This is a monorepo — application IDs are per app. Ask which app under apps/{app}/ to change if ambiguous.
Derive the old application ID from the applicationId field in apps/{app}/android/app/build.gradle.kts.
Then follow every step in the guide below exactly, substituting the old and new values throughout.
Run flutter analyze --no-pub at the repo root at the end before reporting done.

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.

change-app-id is a skill published in the GitHub repository abhinav503/flutter-agentic (10 stars, last pushed 15d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 143 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
