CLI Reference¶

Synopsis¶

trustsight <command> [options]

Global entry point defined in the src/trustsight/cli/ package.

Global flags¶

The help output also documents trustsight config show, trustsight config set <key> <value>, and trustsight config sync-rules with inline examples.

Interrupt handling¶

Ctrl+C during any operation prints Interrupted. and exits with code 130 instead of dumping an SSL/httpx traceback.

trustsight review¶

Scan packages for newer versions on the AUR, produce a diff for each outdated package, run the full analysis pipeline, and print a summary table.

trustsight review [--limit N] [--repo REPO]... [--foreign] [--all-repos] [--verbose] [--score] [--risk]

Flags¶

Flag precedence¶

If any discovery flag (--repo, --foreign, --all-repos) is given on the command line, the [discovery] config section is ignored for that run. Otherwise, the config defaults apply (see Configuration Reference).

Examples¶

trustsight review                      # Foreign packages only (default)
trustsight review --repo aur           # Packages from the aur repo only
trustsight review --repo aur --repo testing --foreign
                                       # aur + testing repos + foreign
trustsight review --all-repos          # All local repos, no foreign
trustsight review --all-repos --foreign
                                       # All local repos + foreign

Behaviour¶

Discovery uses a local AUR metadata snapshot by default:

1. Collects package names and versions from the requested sources (repo contents via pacman -Sl <repo> intersected with pacman -Q, foreign via pacman -Qm, or auto-detected repos via pacman-conf --repo-list).
2. Looks up each installed package in the AUR metadata snapshot (full-aur-meta.json, an offline copy of the AUR package database). On the first run the snapshot is downloaded; subsequent runs reuse it.
3. Filters to packages whose installed version is older than the snapshot version (using vercmp).
4. For each outdated package (up to --limit): clones/fetches the repository, computes a git diff between the last-analysed commit and HEAD, applies the R-series detection rules (R001-R131) and code-structure rules (C001-C007), classifies source URLs into trust buckets, checks novelty against the local database, calculates a deterministic 0-100 score, and generates a verdict.
5. Prints a table with columns: Package, Risk Score, Verdict.

If the metadata snapshot is unavailable or corrupt, the tool falls back to the AUR RPC interface (https://aur.archlinux.org/rpc?v=5&type=info) for the same comparison.

Output¶

Uses rich tables when available; falls back to plain text.

trustsight inspect¶

Show the full analysis for a single package: version diff, maintainer change, diff summary, checksum behaviour, added source URLs with bucket classification, resolved commands, triggered rules, and status.

trustsight inspect <package>

Arguments¶

Flags¶

Output¶

When rich is available:

TrustSight Inspect: <package>
      Version  <old> → <new>
       Lines  +<N> / -<N>
  Maintainer  <current maintainer>
   Checksum  <behaviour>
     Status  <verdict text>

  Files changed
    + PKGBUILD
    ~ .SRCINFO

  Rules Triggered
  <rule_id>  <reason>

  Suppressed by override
  <rule_id>  <override_reason>

  Source URLs Added
    [<bucket>]  <url>

  Resolved Commands
    <command>

      Status  <verdict text>

The --score flag shows per-rule weights (+40) and a Score: N/100 (risk) row with weight sum at the bottom. The --risk flag shows per-rule severities (CRITICAL) and a Risk: (level) row. Without either flag, rules are shown by ID and reason only with a blue border. When both are given, Score row takes priority (it already includes the risk level).

Plain-text fallback prints a condensed subset of the same information.

Database¶

The analysis result (PackageFact serialised to JSON, triggered rules, raw diff) is persisted to the local SQLite database before output is printed.

trustsight history¶

Show analysis history for a package.

trustsight history <package> [--limit N] [--score-breakdown]

Arguments¶

Flags¶

Output¶

Table with columns: Date, Old, → New, Score, Risk.

If --score-breakdown is set, the triggered rules for the latest entry are printed below the table.

trustsight list¶

List all packages tracked in the database with their latest score.

trustsight list [--limit N]

Flags¶

Output¶

Table with columns: Package, Version, Maintainer, Last Checked, Score, Risk.

Packages that have never been analysed show - for score. Version strings that could not be resolved (raw bash expressions, nested parameter expansions) display as unresolved.

trustsight forget¶

Remove a tracked package and all associated history (analysis history, triggered rules, snapshots, profiles, alert state). Package data is removed permanently; source URL and maintainer records are reassigned to the internal sentinel rather than deleted.

trustsight forget <package>...
trustsight forget --prune [--dry-run]

Arguments¶

Flags¶

Behaviour¶

When removing named packages:

1. Deletes alert_state, pkgbuild_snapshots, package_profiles, and package_properties rows keyed by the package name.
2. Deletes triggered_rules rows (via analysis_history).
3. Deletes analysis_history rows.
4. Reassigns source_urls.first_seen_package_id and maintainers.first_seen_package_id to the internal sentinel (id 0).
5. Deletes the packages row.

Reserved names (__seed__, or any name starting with __) cannot be forgotten and raise an error.

Examples¶

trustsight forget aurch                    # Remove a single non-AUR helper
trustsight forget aurch openssl-1.1        # Remove multiple packages
trustsight forget --prune --dry-run        # Show what would be pruned
trustsight forget --prune                  # Remove all non-AUR packages

trustsight status¶

Show database and system health statistics.

trustsight status

Output¶

trustsight config¶

View or modify TrustSight configuration.

trustsight config show
trustsight config set <key> <value>
trustsight config sync-rules [--update]

Subcommands¶

sync-rules¶

trustsight config sync-rules [--update]

rules.toml is written only when it does not exist, so upgrading the package never changes it. An install that predates a rule addition silently never receives that rule, and a corrected pattern never reaches anyone who already has the file.

Adding is always safe and happens by default. Replacing is not, which is why it is opt-in and limited to rules you demonstrably have not customised. trustsight lint-rules reports both conditions.

Config file location¶

~/.config/trustsight/config.toml; created automatically on first run via ensure_default_configs().

trustsight override¶

Suppress a rule that misfires on your packages, with a recorded reason.

trustsight override list
trustsight override add <rule_id> --reason "..." [--package NAME]
trustsight override rm <rule_id> [--package NAME]
trustsight override wizard <package>

Some rules are correct in general and wrong for you. R010 fires on any curl inside a build function; if you maintain a package that legitimately fetches at build time, that finding is noise on every single review, and noise that never goes away is worse than no finding at all, because it trains you to skim.

Subcommands¶

Flags¶

What an override does not do¶

An override removes a finding from the score, but the finding is still recorded and still reported, under a Suppressed by override heading in trustsight inspect, with the reason you gave. A suppression you cannot see is indistinguishable from a detection that never happened.

FATAL rules cannot be overridden. add refuses to create one, and the filter refuses to honour one even if the file is edited by hand. R012 (prompt injection) and R013 (unicode deception) are the two findings an attacker would most want switched off, and both indicate the package is trying to deceive the reviewer rather than merely doing something unusual.

Overrides live in ~/.config/trustsight/overrides.json.

trustsight seed-db¶

Import the novelty seed database, so a fresh install is not cold.

trustsight seed-db [--import] [--file PATH] [--force]

On an empty database every source URL looks first-seen and maturity() returns 0, which gates tier C off entirely and downgrades every Medium verdict to INCONCLUSIVE. The seed supplies both halves of what maturity is really asking about: a body of known AUR source URLs, and a bootstrap observation count.

The seed no longer ships inside the package. It is published as the signed baseline-seed.tar.gz release asset (v2 hashed format) and fetched with trustsight seed fetch; seed-db --file still imports any .db, .db.gz or .tar.gz seed you built yourself. The underlying data is built from the AUR git mirror by scripts/generate_seed.py, which parses each package's .SRCINFO (including the arch-suffixed source_x86_64 arrays, where -bin packages put their real download) and the # Maintainer: comment from its PKGBUILD. URLs are normalised with the same normalize_url() the runtime uses, so a routine version bump matches a seeded entry.

Flags¶

Automatic import¶

trustsight review and trustsight inspect attempt the verified release-channel seed on first use when the database has no seed and no analysis history; on a machine without network, or when the download fails verification, the attempt is silently skipped and the run starts cold. Disable with:

[seed]
auto_import = false

Import takes a few seconds for the full seed and is additive: existing rows win, so a seed can never overwrite something learned from a real analysis, and re-importing is a no-op.

Maturity handover¶

effective_observation_count() returns max(real_analyses, seed_observation_count). Real analyses take over as soon as they outnumber the seed, so ordinary use replaces the bootstrap and the tool never depends on external data permanently.

Trust¶

The seed is derived entirely from public AUR data and is reproducible: re-running the generator against the same mirror produces the same database. The release asset is accepted only when its detached ed25519 signature verifies against the key pinned in the package (fingerprint in baseline keys); the import records the digest of the exact bytes that were verified. It only ever makes novelty signals quieter; it cannot lower a rule score, change a severity, or suppress a finding. A tampered seed could at most hide a novelty signal, never fabricate an UNFLAGGED verdict.

trustsight seed¶

Inspect and migrate the hashed maintainer seed (v0.12.0).

trustsight seed info
trustsight seed stats
trustsight seed migrate [--from-backup]
trustsight seed fetch [--tag TAG] [--key PATH]

Subcommands¶

Flags¶

trustsight db¶

Database maintenance commands: integrity check, vacuum, and backup.

trustsight db check
trustsight db vacuum [--force]
trustsight db backup [--output PATH]

Subcommands¶

Common flags¶

trustsight lint-rules¶

Check rules.toml for rules that are unreachable, over-broad, or malformed.

trustsight lint-rules [--file PATH]

A malformed rule fails silently at runtime. An empty pattern matches every line, and at FATAL severity forces every package to score 100. A pattern that only matches comment text can never fire, because the engine strips comments before matching. Neither failure is visible without a corpus.

Flags¶

Checks¶

How reachability is checked¶

Rules are run through the real matching engine against a small annotated probe diff, so comment filtering and function-body scoping apply exactly as they do in production. Probe lines are tagged benign or suspicious; a high-severity rule firing on a benign line is reported as benign-hit, because a rule that matches ordinary packaging will fire across a large share of the AUR.

Backtracking is measured rather than guessed. Static nested-quantifier heuristics false-positive on safe patterns such as (?:-\S+\s+)*, where the inner and outer character classes are disjoint. Probe inputs are capped at 22 characters (adjusted for Python 3.12+ optimized re engine) so that detecting an exponential pattern does not itself hang the linter.

Exit codes¶

trustsight baseline¶

Build or import a full-AUR baseline corpus. The baseline is a signed artifact containing analysis profiles for every AUR package, priors for novelty detection, and a metadata snapshot for delta computation.

trustsight baseline build [--resume] [--export FILE]
trustsight baseline import FILE

Subcommands¶

Flags (build)¶

Flags (import)¶

trustsight full-aur¶

Bootstrap or update the full-AUR baseline corpus. Fetches the AUR metadata snapshot, downloads PKGBUILDs via codeload (no git repos), analyses stateless rules, and optionally emits a signed baseline artifact.

trustsight full-aur [--bootstrap] [--resume] [--export PATH] [--sign PATH]
trustsight full-aur --watch [--interval SECONDS] [--cycles N]

Flags¶

With a prior snapshot present (any trustsight review run creates one), a cycle processes only the changed packages, which is the intended cadence: run it periodically and the corpus grows incrementally. A from-scratch bootstrap is the exception, gated behind --bootstrap. Either way, each invocation is capped at [limits] corpus_max_per_cycle (default 2000) and resumes, so a large amount of work advances in bounded, resumable chunks rather than one avalanche.

Use --export to produce a shareable baseline that other TrustSight instances can consume via trustsight import-baseline.

What one cycle does¶

1. Fetch the AUR metadata snapshot and diff it against the stored copy.
2. Download and analyse the PKGBUILDs of everything added or changed.
3. Run the Class D corpus sweep over the whole metadata delta, which returns one finding per cluster rather than one per member.
4. Record the cycle into the adoption feed that R125's introduction-rate baseline reads.
5. Report the packages that scored 40 or more this cycle, worst first.

The first cycle of a fresh install is a bootstrap: with no prior snapshot there is nothing to deviate from, so the corpus sweep is silent by construction.

Progress and performance¶

A bootstrap analyses the whole AUR (tens of thousands of packages), and its cost is dominated by one PKGBUILD fetch per package. Two things make that bearable:

• A progress bar. When the output is an interactive terminal, the analysis loop renders a live bar on stderr with the current package, an M/N count, elapsed time and an ETA. It is on stderr so it never corrupts a --export artifact or a piped --json stream; a non-TTY (a cron job, a pipe, --json) falls back to a log line every 1000 packages.
• Parallel fetching, rate-capped. PKGBUILDs are fetched a window ahead, several at a time ([limits] corpus_fetch_workers, default 5). Analysis itself stays strictly serial and in package order, because novelty reads the observations earlier packages recorded; only the fetch is parallelised. The AUR's cgit rate-limits per IP and runs anti-scraping, so the fetcher enforces a global aggregate rate cap (~5 requests/second across all workers) and backs off on 429, 5xx and connection resets, honouring a Retry-After header. Raising the worker count past what the cap can keep busy only idles threads; the cap, not the worker count, is what keeps a 120k-package bootstrap from getting the IP blocked.

Benign per-package fetch fallbacks (a VCS or -bin package with no snapshot tarball falls back to a cgit text fetch) are logged at debug level, so they do not flood the bar; a genuine unfetchable PKGBUILD is counted and the total reported once at the end.

Even so, a full from-scratch bootstrap is roughly a hundred thousand rate-limited fetches, which takes hours and leans on a shared community host. Prefer to let the corpus grow incrementally: run full-aur (or --watch) periodically so each cycle fetches only the small metadata delta, and publish updated baselines over time rather than rebuilding the whole corpus at once.

Watch mode¶

trustsight full-aur --watch --interval 1800

--watch repeats that cycle on an interval and adds memory. A cluster is announced the first time it is seen and counted afterwards, so a quiet night prints nothing instead of re-announcing the same forty-package adoption on every cycle. The record lives in the alert_state table, keyed by package and rule, with a first-seen timestamp and a count.

The interval floor exists because the AUR regenerates its metadata dump every few minutes: anything shorter re-downloads the same snapshot and re-walks the same diff. A mistyped --interval 1 is raised to 60 rather than turned into a request loop against someone else's mirror.

Interrupting with Ctrl-C ends the loop, during a cycle or during the wait. Nothing is lost by stopping: each cycle writes its metadata snapshot and resume file before it returns, so the next run picks up from there.

--watch cannot be combined with --export or --sign. Those describe a single artifact, and pairing them with a loop would silently overwrite it every cycle; the command exits with status 2 instead.

trustsight import-baseline¶

Import a signed baseline corpus artifact. Verifies the signature, then merges profiles, priors, and the metadata snapshot into the local database. After import the database is warm: no cold-start floor, real stable_for_n values, populated priors.

trustsight import-baseline <path>

Arguments¶

Flags¶

trustsight ioc¶

Manage IOC federation baselines. Baselines are signed or unsigned directories containing manifest.json and iocs.jsonl; they supplement the local iocs.toml used by R106.

trustsight ioc sources
trustsight ioc import <dir> [--source NAME] [--allow-unsigned]
trustsight ioc update [--path DIR]...
trustsight ioc list [--source SOURCE] [--type TYPE] [--include-expired]
trustsight ioc export [<dir>] [--source SOURCE] [--json]

Subcommands¶

Flags¶

trustsight corpus pivot¶

Given one indicator, list every corpus package that references it. This inverts R106: instead of asking what a single package carries, it asks who points at a published indicator, which is the question an advisory creates.

trustsight corpus pivot <indicator> [--json]

Arguments¶

Flags¶

Behaviour¶

The match is exact: evil.example matches neither notevil.example nor cdn.evil.example, and a truncated digest matches nothing. The query does not have to appear in iocs.toml; when it does, the entry's provenance and confidence tier are reported with the result.

Only stored corpus material is searched: the AUR metadata snapshot (names, declared dependencies, upstream url=) and the stored PKGBUILD snapshots. Nothing a PKGBUILD points at is ever fetched. Package-name queries read the metadata only, because a name appearing in PKGBUILD text is not a declared fact.

The output names which stores were searched. An empty corpus reports that nothing was searched, never that nothing references the indicator. A miss is uninformative: the indicator list records what has already been reported, so it says nothing about a package it does not name.
