AGENTS.md

Guidance for AI coding agents working in this repository. Document only reflects what exists in code/docs.

Project Type

  • Language: Go
  • CLI: Cobra executed via charmbracelet/fang
  • Module path: git.secluded.site/np
  • Binary name: np

Development Commands (Taskfile)

  • Format: task fmt (installs and runs gofumpt)
  • Lint: task lint (golangci-lint)
  • Static analysis: task staticcheck
  • Tests: task test (go test -v ./...)
  • Vulnerabilities: task vuln (govulncheck)
  • License compliance: task reuse (REUSE)
  • Build: task build (produces ./np, injects version via ldflags)
  • Run: task run -- <flags> (runs with ldflags)
  • Docs: task docs (generates CLI docs via internal/tools/docgen)
  • Pack: task pack (UPX compresses np)
  • Clean: task clean / task clean-all
  • Release: task release (interactive semver release with gum/svu)
  • Full check: task (default runs fmt, lint, staticcheck, test, vuln, reuse)

Single test:

go test -v -run TestName ./path/to/package

Repository Layout

  • main.go: wires fang.Execute(RootCmd) and sets version from build info
  • cmd/: Cobra commands
    • Root and top-level: a (archive), m (monitor/TUI stub), p (plan printout stub), r (resume), s (start)
    • cmd/g/: goal command group; g (show stub), g s (set goal stub with -t/-d)
    • cmd/t/: task command group; t (list stub with status filter flag), t a (add stub), t u (update stub)
  • internal/:
    • db/: Badger wrapper: options, tx helpers, key builders, path hashing
    • goal/: goal document + store
    • task/: task types + store (status index, deterministic IDs)
    • event/: event types + store + payload builders
    • timeutil/: clocks and UTC helpers
    • testutil/: temp DB and test clocks
    • tools/docgen/: CLI doc generator
  • docs/: additional design docs (e.g., Potential schema.md)

CLI Commands (current state)

Commands exist and are registered, but most are stubs that print placeholder output:

np s   # start session (stub)
np a   # archive session (stub)
np p   # print plan (stub)
np r   # resume session (stub)
np m   # monitor TUI (stub)
np g   # goal (stub); np g s -t -d flags defined
np t   # tasks (stub); -s status flag defined; t a/u files exist as stubs

Fang is used for execution/versioning; Cobra provides the command tree.

Data Layer and Storage

Implemented under internal/db, internal/goal, internal/task, internal/event.

  • Database options (internal/db/options.go)
    • Default path: os.UserConfigDir()/nasin-pali/data
    • Retries: MaxTxnRetries (default 5) with exponential ConflictBackoff (default 10ms)
    • SyncWrites defaults to true when not ReadOnly
    • No-op logger by default; Badger logger bridged via adapter
  • Database helpers (internal/db/db.go)
    • View(ctx, fn) for read-only; Update(ctx, fn) for read-write with retries
    • Txn helpers: Get, Set, Delete, GetJSON, SetJSON, Exists, Iterate, IncrementUint64
    • Errors normalized: ErrClosed, ErrReadOnly, ErrKeyNotFound, ErrTxnAborted
    • Iterator uses prefix scans; IterateOptions{Prefix, Reverse, PrefetchValues}
    • Value log size set to 64 MiB when writable
  • Keyspace builders (internal/db/keys.go)
    • Meta/schema: meta/schema_version
    • Per-directory: dir/{dir_hash}/active, dir/{dir_hash}/archived/{ts_hex}/{sid}
    • Global indexes: idx/active/{sid}, idx/archived/{ts_hex}/{sid}
    • Per-session: s/{sid}/meta, s/{sid}/goal, s/{sid}/task/{id}
    • Status index: s/{sid}/idx/status/{status}/{id}
    • Events: s/{sid}/meta/evt_seq (counter), s/{sid}/evt/{seq_hex}; prefixes for scans exist
  • Path handling (internal/db/path.go)
    • CanonicalizeDir: abs + EvalSymlinks + Clean + ToSlash; lowercase on Windows
    • DirHash: blake3-256 of canonical path (hex)
    • ParentWalk: yields canonical parents up to root
  • Encoding helpers (internal/db/encoding.go)
    • Big-endian u64 encode/decode; Uint64Hex for zero-padded lower-hex

Domain Stores

  • Goal (internal/goal)
    • Document: {title, description, updated_at} (UTC)
    • Store: Get, Exists, Set; title is trimmed and required
    • Transaction-scoped TxnStore mirrors operations
  • Task (internal/task)
    • Status: pending, in_progress, completed, failed, cancelled with validation helpers
    • Task: {id, title, description, status, created_at, updated_at, created_seq} (UTC)
    • ID: GenerateID(sid, title, description) uses blake3 of normalized (trim + squash spaces) title/description + sid; first 6 hex
    • Store: Create, Get, Update, UpdateStatus, Delete, List, ListByStatus, Exists
    • Maintains status membership keys; sorts by created_seq, then created_at, then id
  • Event (internal/event)
    • Types: goal_set, goal_updated, task_added, task_updated, task_status_changed
    • Record: {seq, at, type, reason?, cmd, payload}; reason optional; cmd required and trimmed
    • Store: Append, List (supports After and Limit), LatestSequence
    • Sequence stored as 8-byte big-endian counter at s/{sid}/meta/evt_seq; keys use hex-encoded seq
    • Payload helpers in payloads.go build stable snapshots for events

All stores accept an optional timeutil.Clock; default is a UTC system clock. timeutil.EnsureUTC normalizes timestamps.

Testing

  • Tests live under internal/*_test.go (goal, task, event)
  • Helpers: testutil.OpenDB(t) opens a temp Badger DB with cleanup; testutil.SequenceClock yields deterministic times
  • Run: task test or go test -v ./...
  • Example single test pattern: go test -v -run TestName ./internal/task

Doc Generation

  • Tool: internal/tools/docgen (cobra/doc based)
  • task docs runs two invocations: one tree under docs/cli/, and a single-file reference docs/llm-reference.md
  • Note: the Taskfile passes -exclude m but docgen has no -exclude flag; adjust if this causes failures

Output Format for LLMs

  • Status icons: ☐ pending, ⟳ in progress, ☑ completed, ☒ failed, ⊗ cancelled (only show failed/cancelled in legend when present)
  • Commands that change state should print the full plan immediately (current CLI commands are stubs)

Conventions

  • Formatting: gofumpt (not go fmt)
  • Errors and validation follow idiomatic Go patterns visible in stores
  • All source files include SPDX headers; source is AGPL-3.0-or-later; docs/config are CC0-1.0

Gotchas

  • task docs may fail due to -exclude flag unsupported by docgen
  • db.Options sets SyncWrites=true by default when not read-only (durability over throughput)
  • Event sequence counter is raw 8-byte big-endian; do not store decimal strings
  • Windows: directory canonicalization lowercases paths; hashes derive from canonicalized form

Implementation Status

  • CLI commands exist but are stubs that print placeholders
  • Data layer (db, goal, task, event) is implemented with tests; session orchestration and wiring from CLI to stores is not yet implemented
  • docs/Potential schema.md captures intended end-state for sessions, indexes, and events; use as design context, not as a guarantee
