Adds a find_dropped_events tool that exposes Sentry's dedicated events-dropped endpoint to agents. It returns ground-truth data-fidelity information — what Sentry received but dropped (rate limited, over quota, filtered, invalid, abuse/spike protection, client-discarded via sample_rate/before_send, cardinality limited) — bucketed over time, plus the accepted volume per bucket so a caller can compute the dropped share.

`dashboard view --sixel` now renders the complete dashboard into one
Sixel canvas when terminal geometry is known, preserving the original
widget grid. It renders timeseries, categorical bars, scalar values,
tables, text, errors, and unsupported states with a single pixel
renderer, so capable terminals never mix ASCII widgets with Sixel
graphics.

The command always falls back to the complete character dashboard when
Sixel capability or terminal cell geometry is unavailable.

The chart core remains resolution-independent, downsamples dense time
series, preserves the muted gray `Other` series, and provides compact
tick labels.

## Verification

- `pnpm run typecheck`
- `pnpm run lint`
- `pnpm run test:unit` (9,260 passed; 16 skipped)

Coverage includes categorical bars, scalar/table/text/error/unsupported
widgets, adjacent widget positioning, dense-series tails, and the
no-geometry ASCII fallback.

…missing env vars, new commands (#1461)

## Documentation Audit Report (2026-08-24)

Weekly automated audit comparing the CLI implementation against its
documentation. Changes since the last merged audit (PR getsentry#1400,
2026-08-11) include: the `sentry cli completion` command (getsentry#1427), sixel
dashboard rendering (getsentry#1410), the `--environment` explore fix (#1442),
and the 0.43.0 release.

---

## Findings & Fixes

### A. Undocumented or missing commands/subcommands

| Command | Source | Expected doc location | Status |
|---------|--------|----------------------|--------|
| `sentry cli completion` | `src/commands/cli/completion.ts` (added in
getsentry#1427) | `apps/cli-docs/src/fragments/commands/cli.md` | **Fixed** —
added examples for bash, zsh, fish |

All other commands in `src/commands/` have corresponding fragment files.
Hidden backward-compat aliases (`send-event`, `send-envelope`,
`bash-hook`, `whoami`, plural aliases) are correctly excluded from docs.

### B. Undocumented flags

| Flag | Command | Source | Doc file | Status |
|------|---------|--------|----------|--------|
| `--sixel` / `-s` | `sentry dashboard view` |
`src/commands/dashboard/view.ts` | `fragments/commands/dashboard.md` |
**Fixed** — added example |

All other non-hidden flags are auto-generated into the command docs via
`generate-command-docs.ts`.

### C. Missing usage examples

No new gaps. The `sentry cli completion` command was the only command
without examples, now fixed.

### D. Stale descriptions

| Command/Flag | Code brief | Doc description | Status |
|-------------|-----------|-----------------|--------|
| `sentry explore --environment` | Was: "Replay environment filter for
--dataset replays" | Now works for all datasets (fixed in #1442) |
**Fixed** — updated brief to "Environment filter" |

### E. Missing route mappings in skill generator

**N/A** — `ROUTE_TO_REFERENCE` was removed and replaced with automatic
1:1 route-to-reference mapping via `groupRoutesByReference()` in
`script/generate-skill.ts`. No manual mapping to go stale.

### F. Installation / distribution gaps

No new gaps. Install script flags (`--no-modify-path`,
`--no-completions`, `--no-agent-skills`) and env vars
(`SENTRY_INSTALL_DIR`, `SENTRY_VERSION`, `SENTRY_INIT`) are documented
in `getting-started.mdx`. Platform support table matches `.craft.yml`
targets (macOS x64/arm64, Linux x64/arm64, Windows x64).

### G. Undocumented environment variables

| Variable | Referenced in | Expected doc | Status |
|----------|-------------|-------------|--------|
| `DO_NOT_TRACK` | `src/lib/telemetry.ts` | `configuration.md`
(generated from env-registry) | **Fixed** — added to env-registry.ts |
| `SENTRY_PIPELINE` | `src/commands/build/upload.ts`,
`src/lib/build/index.ts` | `configuration.md` | **Fixed** — added to
env-registry.ts |

Remaining niche/internal vars NOT added (intentionally excluded from
user-facing docs):
- `SENTRY_ENVIRONMENT` — bash-hook template only
- `SENTRY_CLI_NO_EXIT_TRAP` — bash-hook template internal
- `SENTRY_SCAN_DISABLE_WORKERS` — internal performance tuning
- `SENTRY_CLI_INTEGRATION_TEST_VERSION_OVERRIDE` — test-only
- `SENTRY_RN_*` — internal react-native wrapper vars
- `SENTRY_TRACES_SAMPLE_RATE` — inherited from SDK, not a CLI config

### H. Auth / self-hosted gaps

No new gaps. OAuth scopes in `self-hosted.md` and `DEVELOPMENT.md` are
auto-generated (`GENERATED:START oauth-scopes`). The `--url` flag for
`auth login` and `SENTRY_HOST`/`SENTRY_URL` behavior are documented.
Token priority (OAuth > env token unless `SENTRY_FORCE_ENV_TOKEN`) is
correct.

### I. Plugin/skills gaps

No new gaps since the last audit. Skills install to `~/.claude` and
`~/.agents` only. The `agentic-usage.md` correctly states this.
Detection of other agents (Cursor, Windsurf, Copilot, etc.) is for
telemetry and the docs correctly list them as "supported" agents (they
can use the CLI, just not via auto-installed skills).

### J. README / DEVELOPMENT.md / contributing.md drift

| File | Claim | Reality | Status |
|------|-------|---------|--------|
| `script/generate-docs-sections.ts` line 210 | "TypeScript types and
Zod schemas" | Migrated to Valibot in getsentry#1389 (merged Aug 7) | **Fixed** |
| `apps/cli-docs/src/content/docs/features.md` | DSN detection table
lists 6 languages with specific `Sentry.init()` patterns | Scanner uses
a universal DSN URL regex across 30+ file extensions | **Fixed** —
updated table to match actual TEXT_EXTENSIONS set |

Node.js version claims (v22.15+ for dev, >=20 for runtime) are correct.
Build commands, test commands, and license (`FSL-1.1-Apache-2.0`) are
all accurate.

---

## Top 5 Most Impactful Fixes (prioritized)

1. **DSN detection language table overhaul** (`features.md`) — The
previous table implied language-specific `Sentry.init()` pattern
matching, which is misleading. The universal regex approach supports 30+
file extensions. Users of Kotlin, Rust, Swift, Dart, C#, etc. would not
have known their DSNs are detected.

2. **Missing `sentry cli completion` docs** (`cli.md` fragment) — New
command from getsentry#1427 with no usage examples. Users discovering shell
completions would miss this standalone alternative to `sentry cli
setup`.

3. **Stale `--environment` flag brief** (`explore.ts`) — After #1442
fixed `--environment` to work for all datasets, the flag's `brief`
string still said "Replay environment filter". Users would think it only
applies to replays.

4. **Missing env vars in registry** (`env-registry.ts`) — `DO_NOT_TRACK`
(industry-standard telemetry opt-out) and `SENTRY_PIPELINE` (build
plugin identification) were referenced in code but absent from the
generated configuration page.

5. **Zod→Valibot drift in project structure**
(`generate-docs-sections.ts`) — The auto-generated project structure
tree in `contributing.md` still said "Zod schemas" despite the migration
to Valibot in getsentry#1389. Contributors would be confused about which
validation library to use.

…missing env vars, new commands (#1461)

## Documentation Audit Report (2026-08-24)

Weekly automated audit comparing the CLI implementation against its
documentation. Changes since the last merged audit (PR getsentry#1400,
2026-08-11) include: the `sentry cli completion` command (getsentry#1427), sixel
dashboard rendering (getsentry#1410), the `--environment` explore fix (#1442),
and the 0.43.0 release.

---

## Findings & Fixes

### A. Undocumented or missing commands/subcommands

| Command | Source | Expected doc location | Status |
|---------|--------|----------------------|--------|
| `sentry cli completion` | `src/commands/cli/completion.ts` (added in
getsentry#1427) | `apps/cli-docs/src/fragments/commands/cli.md` | **Fixed** —
added examples for bash, zsh, fish |

All other commands in `src/commands/` have corresponding fragment files.
Hidden backward-compat aliases (`send-event`, `send-envelope`,
`bash-hook`, `whoami`, plural aliases) are correctly excluded from docs.

### B. Undocumented flags

| Flag | Command | Source | Doc file | Status |
|------|---------|--------|----------|--------|
| `--sixel` / `-s` | `sentry dashboard view` |
`src/commands/dashboard/view.ts` | `fragments/commands/dashboard.md` |
**Fixed** — added example |

All other non-hidden flags are auto-generated into the command docs via
`generate-command-docs.ts`.

### C. Missing usage examples

No new gaps. The `sentry cli completion` command was the only command
without examples, now fixed.

### D. Stale descriptions

| Command/Flag | Code brief | Doc description | Status |
|-------------|-----------|-----------------|--------|
| `sentry explore --environment` | Was: "Replay environment filter for
--dataset replays" | Now works for all datasets (fixed in #1442) |
**Fixed** — updated brief to "Environment filter" |

### E. Missing route mappings in skill generator

**N/A** — `ROUTE_TO_REFERENCE` was removed and replaced with automatic
1:1 route-to-reference mapping via `groupRoutesByReference()` in
`script/generate-skill.ts`. No manual mapping to go stale.

### F. Installation / distribution gaps

No new gaps. Install script flags (`--no-modify-path`,
`--no-completions`, `--no-agent-skills`) and env vars
(`SENTRY_INSTALL_DIR`, `SENTRY_VERSION`, `SENTRY_INIT`) are documented
in `getting-started.mdx`. Platform support table matches `.craft.yml`
targets (macOS x64/arm64, Linux x64/arm64, Windows x64).

### G. Undocumented environment variables

| Variable | Referenced in | Expected doc | Status |
|----------|-------------|-------------|--------|
| `DO_NOT_TRACK` | `src/lib/telemetry.ts` | `configuration.md`
(generated from env-registry) | **Fixed** — added to env-registry.ts |
| `SENTRY_PIPELINE` | `src/commands/build/upload.ts`,
`src/lib/build/index.ts` | `configuration.md` | **Fixed** — added to
env-registry.ts |

Remaining niche/internal vars NOT added (intentionally excluded from
user-facing docs):
- `SENTRY_ENVIRONMENT` — bash-hook template only
- `SENTRY_CLI_NO_EXIT_TRAP` — bash-hook template internal
- `SENTRY_SCAN_DISABLE_WORKERS` — internal performance tuning
- `SENTRY_CLI_INTEGRATION_TEST_VERSION_OVERRIDE` — test-only
- `SENTRY_RN_*` — internal react-native wrapper vars
- `SENTRY_TRACES_SAMPLE_RATE` — inherited from SDK, not a CLI config

### H. Auth / self-hosted gaps

No new gaps. OAuth scopes in `self-hosted.md` and `DEVELOPMENT.md` are
auto-generated (`GENERATED:START oauth-scopes`). The `--url` flag for
`auth login` and `SENTRY_HOST`/`SENTRY_URL` behavior are documented.
Token priority (OAuth > env token unless `SENTRY_FORCE_ENV_TOKEN`) is
correct.

### I. Plugin/skills gaps

No new gaps since the last audit. Skills install to `~/.claude` and
`~/.agents` only. The `agentic-usage.md` correctly states this.
Detection of other agents (Cursor, Windsurf, Copilot, etc.) is for
telemetry and the docs correctly list them as "supported" agents (they
can use the CLI, just not via auto-installed skills).

### J. README / DEVELOPMENT.md / contributing.md drift

| File | Claim | Reality | Status |
|------|-------|---------|--------|
| `script/generate-docs-sections.ts` line 210 | "TypeScript types and
Zod schemas" | Migrated to Valibot in getsentry#1389 (merged Aug 7) | **Fixed** |
| `apps/cli-docs/src/content/docs/features.md` | DSN detection table
lists 6 languages with specific `Sentry.init()` patterns | Scanner uses
a universal DSN URL regex across 30+ file extensions | **Fixed** —
updated table to match actual TEXT_EXTENSIONS set |

Node.js version claims (v22.15+ for dev, >=20 for runtime) are correct.
Build commands, test commands, and license (`FSL-1.1-Apache-2.0`) are
all accurate.

---

## Top 5 Most Impactful Fixes (prioritized)

1. **DSN detection language table overhaul** (`features.md`) — The
previous table implied language-specific `Sentry.init()` pattern
matching, which is misleading. The universal regex approach supports 30+
file extensions. Users of Kotlin, Rust, Swift, Dart, C#, etc. would not
have known their DSNs are detected.

2. **Missing `sentry cli completion` docs** (`cli.md` fragment) — New
command from getsentry#1427 with no usage examples. Users discovering shell
completions would miss this standalone alternative to `sentry cli
setup`.

3. **Stale `--environment` flag brief** (`explore.ts`) — After #1442
fixed `--environment` to work for all datasets, the flag's `brief`
string still said "Replay environment filter". Users would think it only
applies to replays.

4. **Missing env vars in registry** (`env-registry.ts`) — `DO_NOT_TRACK`
(industry-standard telemetry opt-out) and `SENTRY_PIPELINE` (build
plugin identification) were referenced in code but absent from the
generated configuration page.

5. **Zod→Valibot drift in project structure**
(`generate-docs-sections.ts`) — The auto-generated project structure
tree in `contributing.md` still said "Zod schemas" despite the migration
to Valibot in getsentry#1389. Contributors would be confused about which
validation library to use.

…oint

Exposes Sentry's dedicated events-dropped endpoint to agents as a new
find_dropped_events tool: ground-truth data-fidelity information (what Sentry
received but dropped, and why) bucketed over time, alongside accepted volume
so a caller can compute the dropped share.

Surfaced directly (same tier as search_events) since an agent debugging a
flat/spiky/low chart should be able to reach it without discovery.

- api-client: getDroppedEvents() + DroppedEvents response schemas
- tool: find_dropped_events (datasets: spans, logs, metrics)
- registered in the catalog + direct surface; regenerated definitions

Backed by an agent eval: naive agents given a user-phrased question reliably
discovered and called this tool, and attributed flat/spiky charts to the right
drop reason — where the same agents without it concluded "nothing is broken."

Refs DAIN-1863
Remove doc comments that restated project framing / dev decisions rather than
explaining non-obvious code. Matches the surrounding file convention, where
sibling schemas, client methods, and tools carry no such comments. The
caller-facing tool description and param descriptions are unchanged.

Refs DAIN-1863
Three targeted edits to the tool description, keeping the tested structure:
- Lead with what the tool captures (dropped before storage), not "received"
  — SDK-side drops (sample_rate, before_send) never reach Sentry.
- Frame charts as one example of an accepted-only view, not the purpose; the
  tool's role is ground-truth data fidelity: is the data in Sentry or dropped.
- Reframe the trust bullet around confirming data is actually in Sentry before
  relying on a query, aggregate, or dashboard.

Regenerated tool/skill definitions.

Refs DAIN-1863
Adding find_dropped_events to TOP_LEVEL_TOOL_NAMES changes the exact direct
tool set these guardrail tests assert, so add it to DEFAULT_DIRECT_TOOL_NAMES.
The catalog-search test queried 'event stacktrace' at limit 5; find_dropped_events
now ranks there (its name contains 'events'), so raise the limit to 8 to keep
asserting that catalog-only tools remain findable via search.

Refs DAIN-1863
…d_dropped_events

Mirrors two backend changes to the events-dropped endpoint:
- errors dataset now maps to DataCategory.ERROR, so add it to the tool's
  dataset enum alongside spans/logs/metrics.
- outcome (closed set of drop classifications) and reason (open sub-class)
  optionally scope the dropped side; accepted volume is always returned in full.

getDroppedEvents forwards both filters; tool exposes them as optional params.
