- Treat the issue as artifact backpressure: reduce unnecessary files and control what is committed or distributed, without removing valuable regression tests.
- Overalls offers a useful example of isolated development environments, but the available sources do not establish that it automatically cleans up test files or governs documentation.
- V4 already has test and documentation conventions; the main gap is a consistent policy for temporary materials and their lifecycle.
- Before creating an artifact, decide its purpose, location, persistence needs, commit and distribution scope, and retention or cleanup conditions.

The goal: fewer low-value artifacts, not fewer safeguards
V4 can address the growth of temporary tests and documentation by setting clearer rules for the lifecycle of development artifacts. The aim should be to keep disposable work out of lasting project history and shipped packages—not to remove useful regression tests or force every kind of documentation into one file.
That distinction matters: a test can be important to the project while still not belonging in a user-facing release. And a document can be useful without needing to be created for every session.
What Overalls does—and what the evidence does not show
The system in question appears to be Overalls. Geoffrey Huntley’s article describes dispatching agentic coding tasks in ephemeral Firecracker virtual machines and says Overalls was previously known as loom.10 The project’s README, meanwhile, describes a self-hosted platform whose development machines are persistent Firecracker microVMs.

Those descriptions point to isolated development environments, but they do not establish a complete lifecycle for temporary tasks. Nor do the available sources show that Overalls automatically separates test files, organizes draft documents or prevents documentation from growing. The specific X post and image mentioned in the original discussion were not available for verification, so those claims remain unconfirmed.
The useful lesson is narrower: environment isolation can help contain work. It is not, by itself, a policy for test layout, Git commits, documentation or release contents.
V4 has conventions; artifact lifecycle rules are less complete
The repository evidence described in the review shows that V4 already has some structure:
- Long-term tests are collected in
.github/workflows/ci.yml, including contract tests and later asset-protection and distribution checks. Removing test assets casually could break that validation setup. The presence of CI configuration does not mean the checks were run or passed in this review. bmad-suite-v4/rules/bmad-core.mddistinguishes analysis, ADRs, plans, specifications and factual baselines. It also cautions against inventing a new location when a document’s home is unclear..gitignorecovers some runtime directories, sandboxes and temporary files, but does not fully spell out when drafts or verification evidence should be kept. Ignore rules alone do not establish whether a file is currently tracked.scripts/deployment_source.pyrecursively collects ordinary files from the suite source and maps them into a plugin directory. A required-file check is not the same as an explicit allowlist for distribution. Temporary material placed inside the source tree could therefore be included; the evidence does not show that this has happened.
The best next step is not another parallel directory system. It is to make the rules for creating, committing, distributing and retaining artifacts consistent.
Keep lasting tests; isolate one-off checks
“Too many tests” and “the source tree feels cluttered” are different problems. A one-time diagnostic script is not the same thing as a regression test that protects a fix. Avoid sorting files by name alone.
| Artifact | Suggested home | Commit and release approach |
|---|---|---|
| Long-term unit tests, defect regressions and contract tests | The project’s established test layout | Usually keep under version control; decide separately whether they belong in a release |
| One-off diagnostics and temporary verification scripts | An approved task scratch area | Default to not committing or distributing them |
| Logs, coverage data and generated reports | A runtime evidence area | Keep according to acceptance and retention needs; do not add automatically to source history |
| Important counterexamples and reproducible fixtures | Promote to a reviewed, long-term test location | Preserve their regression value rather than leaving them only in scratch space |
Three simple checks can help:
- Before creating a test: Can an existing test be extended? Does a new file cover distinct behavior, or just repeat existing evidence?
- Before committing: Is this a lasting project asset? Does it contain machine-specific paths, credentials or one-off debugging material?
- Before shipping: Is the artifact explicitly part of the deliverable? Being present in the repository should not automatically mean it gets installed.
Test layout also depends on the language. Go’s command documentation distinguishes test files in the package from external test-package files, so a single layout rule should not be imposed across languages.13 A centralized test directory may be worth evaluating for Python, while Go changes should first be checked against package access, test discovery and call relationships.
It also helps to name the underlying problem. If the concern is that installers include tests, adjust the distribution scope. If temporary checks are cluttering commits, adjust the commit policy. If the source tree is difficult to browse, consider layout or display. These are related, but they are not the same fix.
Keep documents focused and connected
V4 can use its existing document roles rather than producing a new file for every conversation:
- Session analysis: deliver in the session by default; do not save it automatically.
_bmad-output/analysis/: reserve for approved analysis, evidence, comparisons and unknowns—not as a general-purpose draft bin._bmad-output/adrs/: record significant decisions and their rationale, not the full research report or execution log._bmad-output/pending_implementation_plan.md: keep goals, authorization, phases, dependencies and acceptance criteria here. Avoid turning it into a running log, and do not overwrite an active plan just because a new suggestion has been made._bmad-output/scratch/: consider it for temporary work, while making clear that its existence does not grant permission to write, execute or clean up files._bmad-output/verification/: retain necessary evidence, with separate rules for committing and retention. Repeated output should not be kept indefinitely by default.
Classify deployment material by purpose: a lasting operations guide is maintenance documentation; a deployment receipt is runtime evidence. A document does not need a new home simply because its title contains the word “deployment.” Any future path changes should preserve references and unfinished work rather than moving historical material wholesale.
To prevent one document from becoming unwieldy, split by distinct subject or decision—not by conversation turn. Let analysis, ADRs and plans serve separate roles and link between them instead of reproducing entire documents. When handing work over, load the current contract and relevant evidence rather than replaying every historical file. Summaries should preserve the difference between facts, inferences and open questions; compression must not turn a hypothesis into a fact.
The idea that fewer files necessarily make an agent more prone to hallucination remains a hypothesis, not an established causal finding. Start by addressing duplication, stale material and irrelevant context rather than setting an unsupported universal page limit or promising a specific effect.
A minimal V4 rule to consider
For every new artifact, state its purpose, home, need for persistence, commit and distribution scope, and retention or cleanup conditions. Prefer extending existing assets where appropriate. Do not require a new file for every verification run or a saved document for every analysis.
If implementation is later authorized, acceptance checks should confirm that relevant CI still discovers long-term tests, temporary artifacts stay out of unnecessary commits and releases, document references remain valid, and cleanup rules do not remove active plans or historical evidence. Directory separation should not be mistaken for execution-level security isolation.
This is a read-only governance proposal, not implementation approval. No files were written, tests run, assets cleaned up or plans replaced as part of the review. The specific X post and image remain unverified, and the available evidence does not confirm that Overalls implements the proposed test or documentation policies.
