What it does

Decompose Architecture Aggregate is an agent skill from jumbocontext/cli. Use when a project has Architecture data that needs migrating to fine-grained entities (Decisions, Invariants, Components, Dependencies). Guides the agent through reading, mapping, confirming, and executing the migration with user oversight.

Its SKILL.md is about 880 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows. The repository describes itself as: Memory and Context Orchestration for Coding Agents. The licence is AGPL-3.0.

When your agent uses it

  • A project has Architecture data that needs migrating to fine-grained entities (Decisions

Example prompts

  • “/decompose-architecture-aggregate”

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Read Current Architecture
  2. Build Proposed Mappings
  3. Present Mappings for User Confirmation
  4. Execute Confirmed Mappings
  5. Present Summary

What it can do on your machine

Read from SKILL.md and the folder at commit a02a339. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Decompose Architecture Aggregate loads about 881 tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 385 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~69
When it runs · the whole SKILL.md, loaded when a task matches
~881

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Decompose Architecture Aggregate

Migrate Architecture entity data to fine-grained entities with user confirmation at each step.

The Architecture entity is deprecated. Its sections map to dedicated entity types as defined in ARCHITECTURE_MIGRATION_MAPPING (src/application/context/architecture/ArchitectureDeprecationConstants.ts):

Architecture SectionTarget EntityCommand
patternsDecisionsjumbo decision add
principlesInvariantsjumbo invariant add
organizationInvariantsjumbo invariant add
dataStoresComponentsjumbo component add
stackDependenciesjumbo dependency add

Protocol

1. Read Current Architecture
bash
jumbo architecture view

Parse the output. If no Architecture data exists, inform the user and stop.

2. Build Proposed Mappings

For each non-empty section in the Architecture view, build a mapping proposal:

  • patterns — Each pattern becomes a Decision. Draft: --title, --context (use the pattern description), --rationale (why this pattern was chosen, if stated).
  • principles — Each principle becomes an Invariant. Draft: --title, --description (the principle text), and --rationale if the source explains why the principle is non-negotiable.
  • organization — Each organization entry becomes an Invariant. Draft: --title, --description (the organizational rule), and --rationale if the source explains why the rule is non-negotiable.
  • dataStores — Each data store becomes a Component. Draft: --name, --type (select from: service, db, queue, ui, lib, api, worker, cache, storage), --description, --responsibility, --path (ask the user if not derivable from the data).
  • stack — Each stack entry becomes a Dependency. Draft: --name, --ecosystem (e.g., npm, pip, maven, service), --package-name, --version-constraint (if known).

3. Present Mappings for User Confirmation

Present all proposed mappings to the user in a single summary, grouped by target entity type. For each proposed mapping, show:

  • The source section and original data
  • The target entity type
  • The drafted command with all flags

Ask the user to confirm, adjust, skip, or augment each mapping. Do not execute any commands until the user has reviewed the full set.

4. Execute Confirmed Mappings

Execute each confirmed mapping one at a time using the appropriate jumbo command:

  • jumbo decision add --title "..." --context "..." [--rationale "..."] [--alternative "..."]
  • jumbo invariant add --title "..." --description "..." [--rationale "..."]
  • jumbo component add --name "..." --type "..." --description "..." --responsibility "..." --path "..."
  • jumbo dependency add --name "..." --ecosystem "..." --package-name "..." [--version-constraint "..."]

Report the result of each command (success or failure) before proceeding to the next.

5. Present Summary

After all confirmed mappings are processed, present a summary:

  • Count of entities created per type (Decisions, Invariants, Components, Dependencies)
  • List of skipped items and the reason (user chose to skip, or data was insufficient)
  • Any errors encountered during execution
