Turns work into multi-step assignments with nested substeps, fork delegation to long-running agent subprocesses, and inspectable session traces. Steps are defined from a catalog, assembled via presets, and driven through a restartable queue.

ace-b36ts encodes UTC timestamps into 2-8 character Base36 IDs that sort chronologically as plain strings. Seven formats from month to millisecond precision, with split output for hierarchical directory paths.

Assembles files, shell commands, and git diffs into a single bundled file. Configured via presets or markdown frontmatter with protocol URL support (wfi://, guide://, tmpl://, prompt://, task://). Output to stdout or cache, with optional compression through ace-compressor.

ace-compressor provides exact, compact, and agent context compression with benchmark comparison, producing structured ContextPack/3 output for efficient LLM context loading.

ace-demo records terminal sessions as reviewable proof-of-work artifacts, with sandbox-isolated YAML tapes and GitHub PR attachment for agent-driven evidence delivery.

Documentation management for teams and agents: track freshness from frontmatter, detect drift from git history, run LLM-powered analysis, and validate consistency across docs.

ace-git gives developers and coding agents focused git context commands and guided workflows for rebases, pull requests, and commit reorganization, with smart diff output and Git 2.23+ guardrails.

Analyzes diffs and developer intent to generate conventional commit messages using LLM. Handles monorepo scoping automatically — split commits across packages with one command.

ace-git-secrets scans Git history for leaked credentials with gitleaks-backed detection, revokes supported tokens, rewrites compromised history, and blocks releases when secrets are still present.

ace-git-worktree creates isolated worktrees for tasks, pull requests, and branches, with task metadata updates, configurable hooks, and cleanup workflows for focused development.

Standardized workflows for creating, reviewing, and maintaining ACE handbook guides, workflow instructions, and agent definitions.

ace-lint provides Ruby-native linting for markdown (kramdown), YAML (Psych), Ruby files (StandardRB/RuboCop), and frontmatter without Node.js or Python dependencies.

Use one CLI for multiple LLM providers with aliases, fallback routing, and structured output options

ace-overseer streamlines focused task execution by provisioning task worktrees, tmux windows, and assignment workflows in one flow.

Provides a single active prompt file with automatic history archiving. Write prompts in your editor, run ace-prompt-prep, get automatic archiving with optional context loading and LLM enhancement.

Run focused, repeatable code reviews using configurable presets and multiple LLM models in parallel. Findings become trackable feedback items with a verify-apply-resolve lifecycle.

ace-search gives one command that auto-detects file vs content search, with preset support and git-aware filtering

ace-sim executes preset-driven simulation chains across multiple providers so teams can validate ideas, review tasks, and compare synthesis outcomes before taking action.

Foundational infrastructure gem providing configuration cascade resolution, environment variable handling, and shared utilities for all ace-* gems. Library-only gem following ace-support-* pattern for infrastructure components.

ace-support-nav provides unified navigation and path resolution across the ACE ecosystem. It automatically discovers handbooks bundled within ace-* gems, resolves resource URIs to actual file paths, and supports a multi-level override cascade.
