What is release-builds?

A post-merge release workflow for a Flutter app. It creates Android releases from version tags, generates iOS IPA files for upload, and saves symbol files used to understand crash reports.

Use it to release Android builds to development, staging, production, or the Play Store, generate iOS IPA files for Transporter, and archive Flutter obfuscation symbols.

It organizes the steps that happen after a release branch is merged and helps preserve the files needed for store delivery and Crashlytics crash analysis.

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	$0.00050	$0.01088
Opus 5.5	$0.00020	$0.00435
Sonnet 5.5	$0.00010	$0.00218
Haiku 4.5	$0.00005	$0.00109

Security

Grade A, and why

release-builds 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/archive_ios_ipa.sh), 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.

Flutter Template Release Builds

Goal

This skill is for the post-merge release-build phase.

It covers:

Android release triggering by tags
iOS IPA generation
archiving IPA files outside the cleaned build folder for Transporter upload
archiving Flutter obfuscation symbols from build/app/outputs/symbols for Crashlytics Dart stack-trace deobfuscation

Android Release Flow

Android releases are triggered by tags after the release branch work is merged.

Current workflow tag patterns:

develop Firebase distribution: v<version>-develop
staging Firebase distribution: v<version>-staging
production Firebase distribution: v<version>-production
Play Store production: v<version>-release

Before tagging:

Confirm the merged commit and intended channel.
Confirm the tag pattern matches the target workflow.
Create the tag on the correct merged commit.
Push the tag and monitor the corresponding GitHub Action.

iOS Release Flow

iOS release builds are manual and should be done one flavor at a time.

Why:

each make target runs make clean
each build clears the build/ directory
IPA files and Flutter obfuscation symbols must be copied out of build/ before the next build if you want to keep all generated artifacts

iOS Build Commands

develop:
- make generateIosDevelopIpa
staging:
- make generateIosStagingIpa
production:
- make generateIosProductionIpa

iOS Artifact Archival Workflow

Immediately after each IPA build, archive the IPA out of build/ios/ipa/ and Flutter obfuscation symbols out of build/app/outputs/symbols before starting the next build.

Use:

.agents/skills/release-builds/scripts/archive_ios_ipa.sh <flavor>

Examples:

.agents/skills/release-builds/scripts/archive_ios_ipa.sh develop
.agents/skills/release-builds/scripts/archive_ios_ipa.sh staging
.agents/skills/release-builds/scripts/archive_ios_ipa.sh production

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
