What is pubspec-manager?

A Flutter package manager that adds Dart or Flutter packages to pubspec.yaml, the file that lists a project's dependencies, by using the Flutter command line.

Use it when adding a regular package or a development-only package such as Riverpod, Dio, or build_runner.

It avoids manual edits that can break YAML indentation or leave package versions inconsistent.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00043	$0.00153
Opus 5.5	$0.00017	$0.00061
Sonnet 5.5	$0.00009	$0.00031
Haiku 4.5	$0.00004	$0.00015

Security

Grade A, and why

pubspec-manager 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 2mo 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

Instructions

When the user asks for a new package (e.g., 'riverpod', 'dio', 'build_runner'), NEVER guess or manually manipulate the Pubspec directly.

Instead, use the run_in_terminal tool to run the CLI command:

flutter pub add <package_name>

If it is a dev_dependency, append the --dev flag:

flutter pub add --dev <package_name>

Inform the user if the package was successfully added.

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.
