fallow — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited fallow (Agent Skill) and scored it 87/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 1 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Used adversarially it removes the human-in-the-loop check before destructive or sensitive actions, turning a normally-gated agent into a fire-and-forget executor.

The primary manifest — the file an agent reads to learn what this artifact does.
Fallow analyzes code and styles for changed-code risk, cleanup opportunities, circular dependencies, duplication, complexity hotspots, architecture boundary violations, design-system styling drift, feature flags, and opt-in security candidates. Runtime coverage merges production execution data into the same fallow health report for hot-path review and cold-path deletion confidence. A single local capture is available by default. Continuous or cloud runtime monitoring is optional.

It starts no analysis, never enables Impact, and compares only whole-project scans. Do not parse this line as JSON.similar-code.json, inspect with --candidates similar-code.json, and pass the unchanged file to fallow similar-code review. Over MCP use find_similar_code with paths: and inspect_similar_code with a typed snapshot; it fails closed on stale source.

Before an edit, run fallow coverage review-packet --repo <owner/repo> (MCP get_cloud_review_packet) for the changed files and read hit_count, covered_by_test, and the callers when present. Before a delete, require period_tracking_state: "never_called", not only tracking_state, and read evidence_window.observed_hours: few observed hours or a low-traffic surface mean "not visited", not "dead". After a deploy, run fallow coverage deployment-changes --repo <owner/repo> (MCP get_cloud_deployment_changes) and, when comparable is false, report reason and claim no change.

Mutate only after consent. On decline, run fallow init --decline --quiet and stay silent for this project.
For guards, inspect fallow hooks status --format json --quiet, then use fallow hooks install --target agent and fallow hooks install --target git. For large backlogs, pair the gate with --save-baseline and new-only guidance.
Offer fallow impact enable for local value tracking. Impact is separate from telemetry. Also offer it once on an already-configured project when fallow impact status --format json has enabled: false and explicit_decision: false. Record a decline with fallow impact disable --quiet.
Report value when there is evidence. If the agent gate blocked a commit or push and a later retry succeeded, describe the issues that caused the block. When next_steps has id impact-report, run its command and report the non-zero numbers in one line. On request, summarize non-zero Impact counts.
Ask about telemetry only after one of these events, and only if fallow telemetry status --format json has explicit_decision: false. Never run fallow telemetry enable.

fallow <command> --help prints the live flag list for any command; fallow schema dumps the whole CLI definition as JSON.
Full command catalogue, one row per command: [references/cli-reference.md](references/cli-reference.md).
Dead-code filter flags select issue categories (--unused-exports, --unused-types, --unused-deps, --unused-files, and so on). Some flags select related types together; --unused-deps covers several dependency types. Passing one or more narrows fallow dead-code to those categories. Passing none applies no issue-type filter.
fallow architecture reports the architecture findings: circular dependencies, re-export cycles, package cycles, boundary violations and rule-pack policy violations. Use --cycles, --boundaries or --policy to select one kind. The JSON output has kind: "architecture" and its own schema_version, with the same arrays and finding ids as dead-code. fallow dead-code still reports these findings until the next major version. Its --circular-deps, --re-export-cycles, --package-cycles, --boundary-violations and --policy-violations flags are deprecated aliases. Run fallow guard <files> before an edit and fallow architecture after it. In bare fallow, --only architecture reports only these findings and --skip architecture removes them.
For suppressible findings, use the placement listed in the issue catalogue: // fallow-ignore-next-line <issue-type> above the finding, or // fallow-ignore-file <issue-type> at the top of the file. Some types support only file-level suppression; others have no suppression comment. A bare supported form without a type suppresses all matching findings at that placement.
fallow explain <issue-type> describes one type without running analysis, and the MCP server serves the same catalogue as the fallow://issue-types resource.
Full catalogue, one row per type: [references/issue-types.md](references/issue-types.md).
Fallow ships an MCP server (fallow-mcp) that exposes these same analyses as agent tools. When the server is connected, its tools are already in your context with typed params and structured JSON returns, and each maps to a CLI fallback command. Prefer them when you want JSON without shelling out, or code_execute (Code Mode) to compose several read-only analyses in one sandboxed snippet (no single-call CLI equivalent). Otherwise use the CLI.
The server also serves read-only reference resources (no subprocess, no analysis run, cacheable by URI; your client reads them through its own resource tool): fallow://tools, fallow://issue-types, fallow://explain/{issue_type}, fallow://task-matrix, and the config, plugin, and rule-pack JSON Schemas. Every resource payload is JSON. Each content item carries the server version in _meta.fallow_version.
Full tool catalogue, resource catalogue, key params, runtime source-map confidence tiers, shared timeouts, and the next_steps dispatch mapping: [references/mcp.md](references/mcp.md).
To set up or modernize the code-quality tooling of a repository (package install, config, agent wiring, CI gate), use the fallow-setup skill.
fallow dead-code --format json --quietParse the JSON output. It contains arrays for each issue type (unused_files, unused_exports, unused_types, unused_dependencies, etc.) plus total_issues and elapsed_ms metadata. Each issue object includes an actions array with structured fix suggestions (action type, auto_fixable flag, description, and optional suppression comment). For dependency findings, a non-empty used_in_workspaces array means the package is imported elsewhere in the monorepo; treat it as a workspace placement issue and do not auto-remove it.

{ "change_anchor": "chg:<from change_anchors>", "framing": "unusedHelper has no caller.", "action": "address" }
]
}Fallow validates the judgment against the live graph. It rejects an id that it did not emit. It refuses the whole file as stale when the hash no longer matches. Report only the accepted judgments. Keep the guide outside the project: a new file in the tree changes the hash. Do not create .fallow/ for it, because a folder that you create has no ignore file. On stale: true, fetch the guide again.

fallow list --plugins --format json --quietShows detected entry points and active framework plugins. Read fallow schema.plugins.count when the exact current registry size matters.
fallow dead-code --format json --quiet --productionExcludes test/dev files (*.test.*, *.spec.*, *.stories.*) and only analyzes production scripts.

fallow dead-code --format json --quiet --changed-workspaces origin/main # CI: only workspaces changed since the refScopes output while keeping the full cross-workspace graph. Patterns are tested against BOTH the package name AND the workspace path relative to the repo root; either match counts. --changed-workspaces <REF> auto-derives the set from git diff (the CI primitive; mutually exclusive with --workspace); a missing ref or non-git directory is a hard error (exit 2) rather than a silent full-scope fallback.
fallow dead-code --format json --quiet --file src/utils.ts --file src/helpers.tsOnly reports issues in the specified files. Project-wide dependency issues are suppressed. Warns on non-existent paths.
fallow dead-code --format json --quiet --include-entry-exportsReports unused exports in entry files (package.json main/exports, framework pages). By default, exports in entry files are assumed externally consumed. This flag catches typos like meatdata instead of metadata.
fallow flags --format json --quiet
fallow flags --format json --quiet --top 20
fallow flags --retirement --format json --quietReports environment-variable gates (process.env.FEATURE_*), SDK calls from common flag providers, and config-object patterns, with flag locations, detection confidence, and a cross-reference against dead code. --top N limits the list. --retirement adds a retirement object with one row per flag, the reasons it can be retired (single-read-site, test-only, literal-constant, identical-branches, empty-branch, guards-dead-code, defined-never-read), and its age from git (--flag-age blame|pickaxe|off; blame gives a lower bound). Filter with --reason <CODE> and --min-age <DAYS>, order with --sort age|sites|name. --flag-state <FILE> reads an offline vendor export in one vendor-neutral schema and adds fully-rolled-out, archived-in-vendor, missing-in-vendor and vendor-only. With --retirement, --save-regression-baseline <PATH> and --fail-on-regression --regression-baseline <PATH> gate on distinct_flags (plus each --reason count), and the opt-in --max-flag-age <DAYS> fails on old flags. Every format works: compact prints flag-retire:<reason>:<path>:<line>:<name>, SARIF adds the rule fallow/flag-retirement-candidate, CodeClimate adds fallow/flag-retirement. The report is advisory: every action has auto_fixable: false, and a person decides what to remove.

# Pre-commit gate: review-required (exit 8) only on NEW candidates in changed lines
git diff --cached --unified=0 | fallow security --gate new --diff-stdin --format json --quietThese are unverified candidates, not confirmed vulnerabilities; an agent must verify trace, reachability, and evidence before editing. --surface adds a top-level attack_surface[] inventory for a verifier. The gate modes are new (candidates introduced on changed lines) and newly-reachable (candidates that became reachable from entry points, which needs --changed-since <ref>); there is no all mode by design. The gate fails with exit 8, distinct from the standard exit ladder.
fallow health --format json --quiet --coverage-gapsReports untested-file and untested-export findings: runtime-reachable code with no dependency path from any discovered test root. Opt-in and requires the full analysis pipeline.

fallow health --format json --quiet --hotspots --group-by owner--ownership implies --hotspots and --effort implies --targets. The global --group-by accepts owner, directory, package, or section (the section mode reads GitLab CODEOWNERS [Section] headers). Hotspots and ownership require a git repository.
# Per-team letter grade + 0-100 score, complexity density, and ownership resolved
# from .github/CODEOWNERS, plus a snapshot for trend tracking. The CODEOWNERS resolver,
# per-owner aggregation, and the graded health formula are all built in - do not
# reimplement owner matching or a scoring formula in a wrapper script.
fallow health --format json --quiet --group-by owner --score --ownership --save-snapshot .fallow/snapshot.json
# Narrow the run to the packages a set of teams owns:
fallow health --format json --quiet --group-by owner --score --workspace 'packages/*'--group-by owner partitions every metric by CODEOWNERS team (last-match-wins, GitHub semantics) with a native resolver, so there is no need to parse CODEOWNERS or aggregate per owner yourself. With --score, each groups[] entry carries a first-class health_score ({ score, grade, penalties: { dead_files, complexity, p90_complexity, maintainability, unused_deps, circular_deps, unit_size, coupling, duplication } }) alongside its own vital_signs and per-file file_scores[] (complexity_density, maintainability_index). Human output renders a ● Per-owner health table (score / grade / files / hot). --save-snapshot records a point-in-time entry that --trend reads later. This one command replaces a hand-rolled CODEOWNERS-resolution + per-owner-aggregation + scoring script end to end.
Caveat for root-only path aliases: in monorepos where TypeScript path aliases (e.g. @myorg/*) are declared only in a root tsconfig.base.json that the per-package tsconfig.json files do not extend, imports through those aliases do not resolve, so dead-code signals (unused files/exports, and the dead_files penalty in the per-owner health_score) carry false positives. The complexity, maintainability, coupling, hotspot, and ownership signals are computed per file from the AST and git history and stay accurate regardless. Prefer health (not dead-code) for per-team quality tracking there.
fallow health --format json --quiet --complexity --complexity-breakdownAdds a per-decision-point contributions[] array to every complexity finding (each if, else-if, loop, boolean operator, and case with its source line and cyclomatic/cognitive weight), so you can pinpoint the exact refactor target.

fallow dead-code --format json --quiet --baseline .fallow/snapshot.json--save-regression-baseline / --regression-baseline / --fail-on-regression / --tolerance are count-based gates for dead-code, architecture, bare combined mode, and flags --retirement (a flags baseline needs a PATH; without --retirement the options have no effect on flags and it warns). --save-baseline / --baseline are identity-based (track finding identity, fail on new). On bare fallow they hold the dead-code baseline only; pass health and duplication baselines with --health-baseline / --dupes-baseline. audit rejects the global baseline flags and uses --dead-code-baseline / --health-baseline / --dupes-baseline instead.
With no path, --save-regression-baseline updates regression.baseline in the discovered fallow config, or creates .fallowrc.json when none exists. Pass a path only when a standalone baseline file is preferred.
fallow explain unused-export --format json
fallow explain code-duplicationThe issue type is a positional argument and accepts forms like unused-export, fallow/unused-export, unused exports, or code duplication. It runs no analysis and returns the rule rationale, a worked example, fix guidance, and the docs URL.

fallow impact statuslinefallow impact enable is a one-time, user-owned local action; the agent-facing lines are read steps. History is stored per-project in the user's private config dir (never inside the repo, so no .fallow/ or .gitignore changes); fallow impact default on enables it for every project at once. The JSON report is read-only and is empty in CI (fallow never records there). The statusline uses only comparable whole-project scans for its trend; legacy changed-file history is labeled explicitly and shown without a trend.
