Agent Building
View on GitHub

Comprehensive codebase assessment for agent and production readiness. Classifies the project (lifecycle, topology, size, stack, shape), scans 8 pillars, verifies commands actually run, checks GitHub settings. Leads with a verdict + ranked next-actions; fixes agent readiness only. Triggers on /flow-next:prime.

Flow Prime

Comprehensive codebase assessment inspired by Factory.ai's Agent Readiness framework.

Role: readiness assessor, improvement proposer Goal: full visibility into codebase health, targeted fixes for agent readiness

Two-Tier Assessment

Pre-check: Local setup version

Compare .flow/meta.json setup_version to the plugin version; on mismatch, escalate once per plugin version. Fail-open throughout: a missing jq, .flow/meta.json, or plugin manifest silently continues.

SETUP_VER=$(jq -r '.setup_version // empty' .flow/meta.json 2>/dev/null)
PLUGIN_JSON="${DROID_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT:-$HOME/.codex}}/.codex-plugin/plugin.json"
PLUGIN_VER=$(jq -r '.version' "$PLUGIN_JSON" 2>/dev/null || echo "unknown")
VERSION_ACK=$(jq -r '.version_ack // empty' .flow/meta.json 2>/dev/null)
if [[ -n "$SETUP_VER" && "$PLUGIN_VER" != "unknown" && "$SETUP_VER" != "$PLUGIN_VER" ]]; then
 if [[ "${FLOW_RALPH:-}" == "1" || -n "${REVIEW_RECEIPT_PATH:-}" \
 || "${FLOW_AUTONOMOUS:-}" == "1" || "${ARGUMENTS:-}" == *mode:autonomous* \
 || "$VERSION_ACK" == "$PLUGIN_VER" ]]; then
 echo "Local setup v${SETUP_VER} differs from plugin v${PLUGIN_VER}. Run /flow-next:setup to refresh local scripts." >&2
 else
 echo "FLOW_SETUP_ASK ${SETUP_VER} ${PLUGIN_VER}"
 fi
fi

If the block printed a FLOW_SETUP_ASK line, before proceeding ask the user with plain-text numbered prompt (local setup differs from the plugin; refresh now?), offering exactly the options Refresh now, Remind me next version, Skip this run, then continue the skill whichever is chosen:

  • Refresh now: pause and have the user run /flow-next:setup in this session (do not run setup yourself), then continue once it finishes.
  • Remind me next version: record the acknowledgement so this version is not re-asked (only a later plugin version re-arms it), then continue. Run this self-contained write (fail-open: on any error, continue anyway):
PJ="${DROID_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT:-$HOME/.codex}}/.codex-plugin/plugin.json"
PV=$(jq -r '.version' "$PJ" 2>/dev/null)
[[ -n "$PV" && "$PV" != "null" ]] && rm -f .flow/meta.json.tmp && jq --arg v "$PV" '.version_ack = $v' .flow/meta.json > .flow/meta.json.tmp && mv .flow/meta.json.tmp .flow/meta.json
  • Skip this run: continue without writing anything; the next invocation asks again.

Any other output (the one-line differs notice, or nothing) is non-blocking: continue.

CategoryPillarsWhat Happens
Agent Readiness1-5Scored, maturity level calculated, fixes offered
Production Readiness6-8Reported for awareness, no fixes offered

This gives you full visibility while keeping remediation focused on what actually helps agents work.

Criteria counts live in pillars.md, never here. pillars.md is the single census source (the legacy scored criteria feeding the maturity level, the informational rows, and the new agent-readiness tier groups AO/DR/TO/HP). Do not restate a count in this file - a hardcoded number drifts the moment a criterion is added. The classification, operability ladder, per-shape playbooks, per-stack matrix, and harness check-set live in the four reference files: classification.md, playbooks.md, stacks.md, harness.md.

Why This Matters

Existence checks lie. A repo can carry a CLAUDE.md, a hook file, and a lint script yet be un-agentic in practice - the file is an empty template, the build is broken, imports don't resolve, or it is really one of 99 sibling repos. Prime judges substance, not existence, and names the single highest-leverage next action.

Agents waste cycles when:

  • No closed verify loop → can't confirm a change works without a full CI round-trip; the feedback gate belongs at the RIGHT layer (edit-time/commit format+lint, tests via the verify command + acceptance requirements + CI required check - never a test-running pre-commit hook agents --no-verify around or stall on)
  • Undocumented env vars → guesses, fails, guesses again
  • No agent instruction file (or a generic/stale one) → doesn't know project conventions, the operability tier, or which files are off-limits
  • The app can't be built or driven → can't verify changes work; a legacy stack with no headless build has no feedback loop at all

These are environment problems, not agent problems. Prime grades them as layered gates and helps fix the ones that help agents work.

Input

Full request: $ARGUMENTS

Accepts:

  • No arguments (scans current repo)
  • --report-only or report only (skip remediation, just show report)
  • --fix-all or fix all (apply all agent readiness fixes without asking)
  • --classify-only or classify only (print the Phase 0.5 classification block and EXIT - the cheap portfolio-triage sweep over many repos; see Phase 0.5 in workflow.md)
  • A path to a different repo root (first non-flag argument)

Examples:

  • /flow-next:prime
  • /flow-next:prime --report-only
  • /flow-next:prime --classify-only ~/other-project
  • /flow-next:prime ~/other-project

Resolve ROOT from $ARGUMENTS (the first non-flag token; default .). If ROOT is not the cwd, it MUST thread through everything: cd "$ROOT" before the .flow/meta.json pre-check, the Phase 0.5 classification probes (the flowctl prime classify emitter takes ROOT as its positional argument, e.g. flowctl prime classify --json "$ROOT"), and the Phase 2 verification commands; and every scout dispatch prompt in Phase 1 starts "Assess the repo at ROOT" (scouts scan cwd by default

  • without this they'd scan the wrong repo and the report would be confidently wrong end-to-end). If threading ROOT isn't feasible, error rather than silently scan cwd.

--classify-only is the fast path: it runs Phase 0.5 (emitter + the skill's judgment layer), prints the classification block, and exits - it NEVER asks (Phase 0.6 is skipped), NEVER dispatches scouts, and NEVER remediates. It must stay cheap (<~10s even on a multi-M-LOC repo).

The Eight Pillars

Agent Readiness (Pillars 1-5) — Fixes Offered

PillarWhat It Checks
1. Style & ValidationLinters, formatters, type checking, pre-commit hooks
2. Build SystemBuild tools, commands, lock files, monorepo tooling
3. TestingTest framework, commands, coverage, verification
4. DocumentationREADME, CLAUDE.md, setup docs, architecture
5. Dev Environment.env.example, Docker, devcontainer, runtime version

Production Readiness (Pillars 6-8) — Report Only

PillarWhat It Checks
6. ObservabilityLogging, tracing, metrics, error tracking, health endpoints
7. SecurityBranch protection, secret scanning, CODEOWNERS, Dependabot
8. Workflow & ProcessCI/CD, PR templates, issue templates, release automation

Workflow

Read workflow.md and execute each phase in order.

Key phases: 0.5. Classify - host-inline five-axis classification (lifecycle / topology / size / stack / shape) via the flowctl prime classify emitter + the skill's judgment layer, per classification.md. Parameterizes everything downstream (scout dispatch, N/A denominators, report shape, playbook selection). --classify-only prints this block and exits. 0.6. Targeted clarification - the bounded R15 ask protocol: at most one question call for low-confidence or uninferable facts that change a playbook or verdict; confirmed answers offered for durable recording in the agent file. Suppressed under --classify-only / --report-only / autonomous.

  1. Parallel Assessment - 9 scouts run in parallel (7 haiku fast scanners; agents-md-scout + docs-gap-scout on sonnet for judgment), each consuming the Phase 0.5 classification (~15-20 seconds)
  2. Verification — Verify test commands actually work
  3. Score, Synthesize & Assemble the Verdict - Calculate pillar scores + maturity level (includes the deterministic DC8 glossary signal - flowctl glossary list --json, gated on total_terms == 0, never file presence); evaluate the host-inline AO/DR/TO/HP groups as level-excluded pass-count lines; derive the DR-core QA-readiness line + feedback-latency + gh-CLI host lines; assemble the verdict headline inputs
  4. Present Report — Full report with all 8 pillars
  5. Interactive Remediation — plain-text numbered prompt for agent readiness fixes only 5.5. Glossary Bootstrap — when the glossary has zero terms (absent or husk), propose evidence-backed terms from the repo and seed GLOSSARY.md via flowctl glossary add after read-back approval; a populated glossary gets a coverage line, never a rewrite
  6. Apply Fixes — Create/modify files based on selections
  7. Summary — Show what was changed

Maturity Levels (Agent Readiness)

The maturity level is secondary metadata, NOT the headline. The report LEADS with the verdict headline - classification line + operability tier + hard-gate status + top-5 ranked next-actions (see playbooks.md). The level moves below the scores table: at portfolio scale a bare "Level 5" from existence checks is exactly the false signal this skill exists to retire. The level still computes for cross-repo comparability, but a reader acts on the ranked actions, not the badge.

LevelNameDescriptionScore
1MinimalBasic project structure only<30%
2FunctionalCan build and run, limited docs30-49%
3StandardizedAgent-ready for routine work50-69%
4OptimizedFast feedback loops, comprehensive docs70-84%
5AutonomousFull autonomous operation capable85%+

Level 3 is the target for most teams. Don't over-engineer.

The score band above is necessary but NOT sufficient. The maturity level ALSO requires the per-pillar floors defined in pillars.md (Level 3 needs every pillar ≥40%, L4 ≥60%, L5 ≥80%). pillars.md is the single source — compute the level there, not from this table alone, or a repo at 72% overall with one 45% pillar gets reported "Level 4" when it's Level 3.

Guardrails

General

  • Never modify code files (only config, docs, scripts)
  • Never commit changes (leave for user to review)
  • Never delete files
  • Respect .gitignore patterns

User Consent

  • MUST ask via the plain-text numbered prompt described below for consent.

Ask the user via plain text. Render the options below as a numbered list 1. … N., followed by a final option N+1. Other — type your own answer. Print the question, then the numbered list, then stop and wait for the user's next message before continuing. Parse the reply as: a bare number 1–N+1 → that option; the literal text of an option label → that option; free text after Other → custom answer.

  • Always ask before modifying existing files — except under --fix-all, which waives the prompt for append/merge edits (adding a .gitignore line, augmenting an agent file, appending a hook) INCLUDING their required devDependencies for the Critical/High/Medium tiers. --fix-all still does NOT: overwrite/replace existing file content unseen, touch the Bonus tier (devcontainer, CI workflow — those stay explicit-request-only), or bypass the glossary read-back gate. A destructive overwrite always needs consent even under --fix-all.
  • Don't add dependencies without consent (a Critical/High/Medium fix's own devDeps are covered by that fix's consent, incl. --fix-all; never add unrelated deps)
  • Glossary terms are never written unseen — the Phase 5.5 bootstrap shows the full proposal (term + definition + file-ref evidence) at read-back before any flowctl glossary add; --fix-all does not bypass this gate, and a populated glossary (total_terms > 0) is never rewritten

--fix-all boundaries (resolutions 5/6)

--fix-all auto-applies ONLY in-ROOT, non-structural, non-harness fixes at the Critical/High/Medium tier - the in-root Pillars 1-5 fixes PLUS scored-group agent-file content whose catalog row is marked --fix-all-eligible in its consent column (the ranked catalog carries the tier AND consent columns and is authoritative on which scored-group items qualify - see playbooks.md). It NEVER waives consent for:

  • Anything outside the repo ROOT - the home-base / constellation kit (parent instruction file, repos.yaml, run-everything scripts) is always explicit-consent-only.
  • Any harness settings/hook file - deny/ask rule scaffolds, hook wiring, MCP config. A scaffolded hook is exercised in the same pass (never a stub); the offer itself still needs explicit consent.
  • All structural / playbook artifacts - a generated map, nested per-package instruction files, the home base, the greenfield bootstrap plan. Structural = restructures the repo → explicit consent regardless of tier.
  • On greenfield, --fix-all applies ONLY to exercised hygiene files (.gitignore, lockfile, .env.example, .editorconfig) - never structural or generated artifacts, and never a bulk-generated instruction file (measured harm).

Re-run reuse (resolution 6): a Phase 7 re-assessment reuses the session's Phase 0.5 classification and R15 answers; only the affected criteria/gates re-verify. The ranked catalog is re-ranked from the updated scores, not re-derived from scratch, and prime does not re-ask a question the user already answered this session.

Scope Control

  • Never create LICENSE files — license choice requires explicit user decision
  • Never offer Pillar 6-8 fixes — production readiness is informational only
  • Focus fixes on what helps agents work (not team governance)

Scouts

Agent Readiness (haiku fast scanners; agents-md-scout + docs-gap-scout on sonnet)

  • tooling-scout — linters, formatters, pre-commit, type checking
  • agents-md-scout — CLAUDE.md/AGENTS.md analysis (sonnet — judgment-heavy)
  • env-scout — environment setup
  • testing-scout — test infrastructure
  • build-scout — build system
  • docs-gap-scout — README, ADRs, architecture (sonnet — judgment-heavy)

Production Readiness (haiku, fast)

  • observability-scout — logging, tracing, metrics, health
  • security-scout — GitHub settings, CODEOWNERS, secrets
  • workflow-scout — CI/CD, templates, automation

All 9 scouts run in parallel for speed.
