incredigo/CLAUDE.md

incredigo — project directive for Claude sessions

incredigo is a local-first, encrypted, RAM-only credential custody tool (Go). The folder is still named credrot/; the module/binary are incredigo.

Read this first, then VISION.md (who it's for + the mission), DESIGN.md (architecture + threat model), docs/MARKET.md (competitive landscape + positioning) and — if present locally — docs/ROTATION.md (rotation design; gitignored, shared individually, not on the upstream repo).

Vision — catch vibe-coding security disasters before they happen

The primary user is the vibe coder: the fast-moving AI-assisted builder (OpenClaw / Hermes / Claude-Code / Cursor) who ships in a weekend and accumulates dozens of credentials — .env keys, sk_live, DATABASE_URL, GitHub PATs, AWS keys, Supabase service_role — each generated once, pasted in, and never rotated. incredigo finds that sprawl on the machine, custodies it in RAM, backs it up, rotates what's scriptable, and guides the human through the rest — before a forgotten key becomes a breach. Secondary user: the non-technical password reuser (weak/reused passwords saved in the browser) — same engine, friendlier face, via the browser worklist + change-URL links.

Tailor every feature to those two. Do NOT build toward enterprise PAM / machine-identity-at- scale / compliance-cert / SaaS-hub territory — that's the incumbents' moat. The target credential surface (the driver + scanner roadmap) is the 20-credential list in VISION.md. Full crystallized vision in VISION.md; competitive rationale in docs/MARKET.md.

North-star goal

A user or organization can rotate their credentials with one tool, two modes:

• Mode A — rotate what's already in gopass.
• Mode B — ingest creds first (scanners / --path / browser CSV), then rotate.

Both must run interactively or fully headless ($INCREDIGO_PASSPHRASE, no TTY): do the automatable rotations unattended, and emit a guided worklist (+ links) for the credentials that legitimately require a human. See docs/ROTATION.md Part II.

Where development is (2026-06-15)

• v1 shipped: discover → migrate → expiry → sealed export/import. 8 scanners (aws, env, netrc, ssh, docker, kube, git, file/--path); sealers age (default), hmac, openssl. Tests green, -race clean.
• Rotation: design + safety-spine + guided manual layer. internal/rotate has the Rotator interface and the mandatory backup gate (Snapshot); dry-run incredigo rotate refuses --execute. The guided layer is built and read-only: internal/links (offline change-password URL generation: curated table + RFC 8615 well-known + host fallback), internal/worklist (secrets-free worklist), and internal/tui (Bubble Tea walk-through) — surfaced as incredigo worklist and incredigo guide. Zero rotation drivers exist; nothing changes a credential at any service yet — keep it that way until explicitly authorized.

Hard rules (do not violate — this tool holds real credentials)

1. Backup before rotate, always. No rotation may run unless rotate.Snapshot has produced a verified sealed backup of the affected entries first. The gate aborts the run on any backup/verify failure. This is non-negotiable.
2. Verify-new-before-revoke-old. Order: backup → rotate → verify the new secret authenticates → store in gopass → re-read → only then revoke the old. Never gopass rm an old value before the new one is proven (SSH/DB = lockout risk).
3. No plaintext secrets on disk. Ever. Secrets live only in the memguard vault and stream as bytes. Browser passwords → worklist of non-secret metadata (site, username, change-URL), never a .txt password dump. Raw export is a loudly-warned, flag-gated opt-in only.
4. gopass test isolation = GOPASS_HOMEDIR, NOT PASSWORD_STORE_DIR. gopass ignores PASSWORD_STORE_DIR; gopass init --path … repoints the user's real root mount and breaks their store. Always isolate tests with export GOPASS_HOMEDIR=$(mktemp -d) + a throwaway GNUPGHOME. Better: unit-test against a fake gopass binary via sink.Gopass{Bin: …} (see internal/sink/bundle_test.go, internal/rotate/backup_test.go).
5. Do no harm / self-owned only. Browser automation targets only the user's own accounts, with their authorization. Never bypass MFA/CAPTCHA — hand off to the human. Nothing here may resemble credential stuffing or account takeover.
6. Dry-run by default; destructive steps are opt-in, audited, reversible. The redacted audit log records every action. Computer-use/vision automation must inject secrets locally and never stream them into the model loop.
7. The PGP passphrase is the root of trust. It unlocks every gopass secret. The TUI and docs MUST warn prominently: lose it → everything is unrecoverable; leak it → everything is exposed. Tell users to back up the GPG key and use a strong passphrase. Treat this warning as a required UX element, not optional.

Build / test / run

go build ./...            # green required before commit
go vet ./...
go test ./...             # all packages; -race clean on vault/sink/rotate
go build -o /tmp/incredigo ./cmd/incredigo

Never run incredigo migrate/export/rotate against the user's real gopass to "test" — use an isolated GOPASS_HOMEDIR (rule 4).

Architecture

cmd/incredigo        cobra CLI: scan|migrate|status|export|import|rotate
internal/vault       memguard arena (mlock/DONTDUMP, zeroize, handles)
internal/discover    Scanner registry + one file per source
internal/sink        gopass streaming, bundle framing, Sealer (age/hmac/openssl)
internal/policy      expiry engine
internal/audit       redacted append-only JSONL
internal/rotate      Rotator interface + MANDATORY backup gate (no drivers yet)

Extension points stay one-file-each: a Scanner, a Sealer, a Rotator. Drivers and the backup gate live in Go; the AI router + browser long-tail belong in a skill/MCP layer on top (do not put an LLM in the deterministic destructive hot path).

Chosen stack (2026 research, see ROTATION.md §13)

• TUI: Charm Bubble Tea + Bubbles + Lipgloss (masked input via textinput).
• Browser automation: go-rod (default) → playwright-go (reliability) → Anthropic Computer Use (vision fallback, secrets kept out of the loop).
• Per-site links: .well-known/change-password (RFC 8615) + a curated table.

Conventions

• Match surrounding Go style; comment the why for any security-relevant choice.
• New code ships with tests (table-driven scanners; leak-checks asserting no secret substring reaches Identity/Meta/logs).
• Commits: end messages with the Co-Authored-By: Claude … trailer. Push only when asked. Remote is gitea only, never GitHub (https://100.117.177.50:3030/trill-technician/incredigo).
• Design docs (docs/ROTATION.md) are kept local/gitignored by request; VISION.md, DESIGN.md, README.md, docs/MARKET.md, docs/SECURITY.md, docs/ADDING_A_SCANNER.md are tracked.
