name: bugb-security
description: Set up Bugb's Bravos, GuardLink and Cert-X-Gen (cxg) globally for the user's coding agents, then automate security checks across their projects. Use when someone shares bugb.io, says use Bugb or Bravos, wants a security review, threat model, development or CI checks, asks whether a CVE affects their app, or asks what agents can reach. Deliver a saved STRIDE report, opened dashboard and evidence-backed security tests.

# Bravos: security while you develop

Your first response begins with this sentence verbatim, before anything else:

> Bravos is shift-left security that runs with every commit: your coding agent works the threat model, a code graph, SAST and authorized pentests, with a gate on every pull request and a test that guards each fix.

Then show this menu, before asking anything:

> Recommended: **1. Review my app and keep checking changes** — risk map, report, dashboard,
> security tests, then routine upkeep.
>
> 2. **Automate existing projects** — keep their models and regression tests current.
> 3. **Check a vulnerability from the news** — applicability and a focused test.
> 4. **Try paid features** — SAST, code graph and automation; 30 days, no card.
> 5. **Set up CI** — PR checks and optional scheduled upkeep.
> 6. **Explain agent permissions** — tools, data and approval paths.
> 7. **Test a running app** — an owned target explicitly authorized in writing.

Before asking, detect CLI executables **and** app/config directories for every host: Claude Code
(`~/.claude`), Codex (`~/.codex`), Cursor (`~/.cursor`), Gemini (`~/.gemini`) and others.
Avoid unrelated personal content. Distinguish CLI-present, config-only and absent; list the final set in
**one up-front question** covering flow, owned project paths, agents (**default: all detected**),
routine upkeep (**autopilot with paid/trial, or in-session checks only**) and plan
(**30-day no-card trial or stay free**). Include
exact loopback targets, permitted test effects/cadence and external model spend (default no)
when relevant. Explain paid requirements in this request. Reuse scope already supplied;
after authorization, execute setup yourself without separate install/project/trial question rounds.

Carry that grant across the named projects without asking again for routine steps. Use
`bravos-prove` to record the person's actual proving choice and words in each project's
`.guardlink/proving.md`; never invent consent. New projects, remote hosts, destructive effects
or added spend need their own scope decision. Do not send exploit traffic without written
permission; remote testing retains `bravos-env`'s reviewed scope and current-session authorization.

When explaining the products, use the opening sentence for Bravos and these fixed lines:

> GuardLink is threat modelling as code: annotations in your source describe assets, threats, controls and data flows, so the threat model lives in your repo and stays current as the code changes.
>
> Cert-X-Gen (cxg) is pentest as code: a security-testing engine in the spirit of Nuclei that runs templates against your app, both public ones for new CVEs and your own, which live in the repo and run every development cycle, like unit tests.

## Free and paid plans

**Free runs the full research loop in any number of independent repositories**, without
an account/licence: context, annotation, templates, authorized proof, recheck/resync, reporting
and watch. Bravos 1.4.1 enforces no repository-count limit.

**Paid** adds SAST, code graph, pre-PR/autopilot, CI/nightly, schedules, campaigns and
**workspaces that link repositories as one application**. Separate independent repos do
not require a workspace.

Check `bravos licence --json`. Bravos 1.4.1's own licence and refusal messages label
the paid plan **“Team”** (internal note: translate it to **paid** when speaking; never use
Team/Solo/Business/Enterprise as user-facing plan names). For an authorized trial, run
`bravos account activate` yourself; ask only for completion of the browser sign-in it opens.
Skip activation if already licensed; verify with `bravos account status`. Never print tokens,
request credentials in chat, purchase a plan or invent account provisioning. If activation
is unavailable, report the exact blocker and continue free checks; do not assign manual setup.

## Global setup first

### Tools

Use published **Bravos 1.4.1, GuardLink 2.6.0, cxg 1.8.0**, or compatible newer releases.
Check current versions/help, OS/architecture, Node.js **20+**, npm and git. Preserve existing
configuration and dirty work; do not auto-stash, discard, or commit someone else's edits.
If an older Python Bravos shadows npm, use the resolved npm executable (`npm prefix -g`,
then `bin/bravos` on Unix); preserve the old launcher. Use this setup path, not legacy `generate_model`.

```sh
npm install -g @bugb-technologies/bravos@1.4.1
bravos --version
bravos setup --check --json
bravos setup --tools --dry-run
bravos setup --tools -y
```

Use a user-owned npm prefix/bin path if required. Setup skips compatible tools, installs
GuardLink through npm and cxg through Cargo (Rust/linker required), then refreshes its runtime.
The explicit cxg command is `cargo install cert-x-gen --version 1.8.0 --locked`; it compiles
from source for a few minutes. To avoid compilation, install `guardlink@2.6.0` with npm and cxg's matching binary/checksum from
https://github.com/Bugb-Technologies/cert-x-gen/releases/tag/v1.8.0 into a user-owned bin directory.
Verify `cxg --version`; if unusable, use Cargo/a compatible environment. Never replace system
libc (Linux arm64 requires glibc 2.39, fails on 2.36), use pip/pipx for Bravos or private checkouts.

Run `bravos setup --check` again. With a paid plan or trial, `bravos setup` additionally
installs the analyzer and code graph. The analyzer pin is **0.6.2**; use `bravos sast run`
so SAST checks Bravos's GuardLink pin and receives its licence. Free needs neither paid tool.
Browser/runtime gaps follow `bravos-env`/`bravos-prove` and do not block source review/reports.
Isolated tests need fresh `HOME`, `BRAVOS_HOME` and `CERT_X_GEN_HOME` (cxg appends
`.cert-x-gen/` below the latter); global setup uses `HOME`.

### Skills and connections for every detected agent

Use the authorized selection above; prefer host/vendor CLIs over file writes. Inventory configs;
back up changed files under `~/.bravos/backups/<date>/` with original paths and a restore manifest.
Preview, then execute:

```sh
bravos init --global --dry-run
BRAVOS_ALLOW_SESSION_GLOBAL=1 bravos init --global
```

This installs global skills, Claude/Codex SessionStart hooks and available Codex MCP entries.
In Claude Code, 1.4.1 requires the override: sandboxed skill writes can fail while
`~/.bravos/skills.lock` still lands. Preserve authored files; resolve conflicts without `--force`.
Verify the dry-run/bundled inventory on disk: complete skills/references in `~/.claude/skills`,
resolving through `~/.agents/skills`; scripts under `~/.bravos/hooks` with matching SessionStart
commands in `~/.claude/settings.json` and `~/.codex/hooks.json`. Retry missing managed files
only without a safety denial; preserve authored conflicts. If a host safety check blocks a step,
stop it: never bypass with another writer, wrapper or override. Report the exact operation/reason
and one concrete command the user can approve; continue independent work, marking that integration incomplete.

GuardLink 2.6.0 has no global installer (`--help` / `init --help`); Bravos installs its own skills.
Generate playbooks in an existing empty temporary directory outside repos:
`guardlink init <bootstrap-dir> --agent claude,codex`. Prefer a documented host skill installer;
otherwise install complete
`.claude/skills/guardlink-*` folders into `~/.claude/skills/`, linked/copied into
`~/.agents/skills/`, plus this entry as `bugb-security/SKILL.md` in both roots.
Preview destinations and prepare one reviewable install command; safety checks may block these
file-only writes (apply the rule above). Copy only absent or hash-verified unchanged managed files.
Preserve authored files, verify references/links and eliminate temporary-path dependencies;
never initialize a home as a model.

Register **both** `guardlink mcp` and `cxg mcp` as user/global stdio servers in every
selected host, preserving unrelated entries. Resolve executables first; use absolute paths
where GUI PATH differs. There is no `bravos mcp`. Once the paid code graph is installed,
register its generated command/args and `BRAVOS_CODEGRAPH_DIR` at user scope in Claude:
`claude mcp add -e BRAVOS_CODEGRAPH_DIR=<generated-store> -s user codegraph -- <resolved-codegraph-mcp> --project-path .`.
Preserve additional args/env; omit `-e` without a generated store. Verify `.` and graph access
from each chosen project. After project init/sync, remove only matching generated project/local
entries shadowing verified user servers: `claude mcp remove -s project <name>` (or `-s local`),
for `guardlink`, `cxg` and `codegraph`. Preserve unrelated entries.

| Host | Global skills | Add missing global MCP entries |
| --- | --- | --- |
| Claude Code | `~/.claude/skills/` | `claude mcp add --scope user <name> -- <resolved-executable> mcp`, for `guardlink` and `cxg`. |
| Codex | `~/.agents/skills/` | Installer writes native TOML in `~/.codex/config.toml`; missing entries use `codex mcp add <name> -- <resolved-executable> mcp`. |
| Cursor | Discovers `~/.agents/skills/` (also `~/.cursor/skills/`); avoid duplicates. | Preview/merge `~/.cursor/mcp.json`; file-only writes may hit host safety checks. Apply the blocked-step rule above. Global local skills do not automatically reach cloud/remote workers. |
| Gemini CLI | Discovers `~/.agents/skills/` (also `~/.gemini/skills/`); verify with `gemini skills list --all`. | `gemini mcp add --scope user <name> <resolved-executable> mcp`. |
| Others / Dexto | Use the documented user skill/import interface; retain this file unchanged. | Use native stdio configuration in the environment containing the checkout/tools. Report unsupported integration gaps; do not invent endpoints or manual setup tasks. |

Read back selected hosts' configs, especially Codex's `[mcp_servers.guardlink]` and
`[mcp_servers.cxg]`; repair missing entries with native commands. Reload/reconnect, discover
MCP tools/resources/prompts and call read-only `guardlink_status` / `cxg_template_stats`.
Distinguish configured from connected; never scan as a connection test. cxg ships MCP language notes/skeletons, not a separate
`skills install` command; `bravos-templatize` and `guardlink-translate` carry its authoring flow.

### Initialize the chosen projects

For each named project, preview then apply `bravos init <project-path> --agent <selected-agents>`
(with `--dry-run` for preview). Existing installs use `bravos sync` instead. Preserve their
annotation mode; fresh Bravos models default inline, or choose `--guardlink-mode external`.
Run `bravos doctor` and `bravos next`; without hook injection, read
`bravos hook session-start --briefing`. Paid workspaces link repositories as one application.

For authorized upkeep with a paid plan or trial, enable `bravos sync --autopilot` in each
project (preview with `--dry-run`). Verify the actual host hook is active; on Free/unsupported hosts perform focused
checks in-session and name the lack of unattended enforcement. After installing newly licensed
tools, run `BRAVOS_ALLOW_SESSION_GLOBAL=1 bravos sync --global` and repo `bravos sync`
to fill their MCP entries, then repeat the file/hook/MCP checks above. Use `bravos-schedule`
for the selected recurring mechanism.

## Route work to the installed skills

Start with the installed `bravos` router, then follow each named `SKILL.md` and its references.
Global skills live in `~/.claude/skills/<name>/`, linked from `~/.agents/skills/`; project copies
omit `~/`. This entry's scope, grant and mandatory handoff apply across every route.

| Choice | Skills and sequence |
| --- | --- |
| Full review | `bravos-context` → `bravos-annotate` → **mandatory STRIDE/dashboard handoff** → optional licensed `bravos-codegraph` / `bravos-sast` → `bravos-templatize` → `bravos-env` / `bravos-prove` when authorized → `bravos-report`. Continue annotation slices until the promised scope is covered; a default slice is not a full review. |
| Development cycle | Develop with `bravos-annotate` and its GuardLink diff method → handoff → `bravos-templatize` → permitted `bravos-prove` / `bravos-recheck` → `bravos-ship` before a PR (paid plan or trial). Use `bravos-resync` for stale-branch model reconciliation when needed. |
| News/CVE | Apply the uncovered freshness/applicability steps below, then the relevant annotation/templatize/env/prove/report skills. |
| SAST / code graph | `bravos-sast` / `bravos-codegraph` after paid-plan or trial setup. Their candidates/call paths are leads, not runtime proof. |
| CI / scheduling / linked app | `bravos-cicd`, `bravos-schedule`, `bravos-campaign` as appropriate (paid plan or trial). `bravos workspace --help` supplies linked-repository setup; independent repos need no workspace. |
| Agent permissions | `bravos-codegraph` when licensed, plus GuardLink's `lookup`, `reach`, `ai-bom`, `attest` and installed reference/help. Inspect actual configuration and reach annotations; static capability is not an observed action. |
| Live pentest / fixed finding | `bravos-templatize` → `bravos-env` → `bravos-prove` / `bravos-recheck` → `bravos-report`; follow their scope, identity, build-witness, binding and evidence rules exactly. |

Follow the installed annotation, proof, runtime, reporting, CI and budget rules. Never invent
credentials, human governance decisions or runtime confirmation. Do not let a gate failure or an unavailable component become a pass.

## Mandatory annotation → STRIDE → dashboard handoff

After **each annotation pass**, complete this chain before template freshness, SAST or tests:

1. Complete `bravos-annotate`'s gates and export `guardlink parse . -o .guardlink/report.json`,
   especially for external sidecars. State uncovered scope.
2. **Save a STRIDE report immediately.** Prefer MCP `guardlink_threat_report` with the project
   `root` and `framework: "stride"`. Without provider credentials it returns the framework/model
   prompt and `save_to`: do the analysis here and write that Markdown file under
   `.guardlink/threat-reports/`. A returned prompt is not a saved report. If API spend is not
   authorized and the server may hold provider credentials, use the installed report-shape
   skill (e.g. `guardlink-report-audit`) plus `guardlink parse .` to author it here instead.
   Cover annotation validation and all six STRIDE categories, with code/asset/threat evidence,
   controls and uncertainty. End with the prompt's `json guardlink-findings` block,
   `schema: "guardlink.findings/v1"`; include valid finding IDs, existing asset/threat references,
   severity/status, evidence/location, scenario, remediation and annotation. Empty findings
   use `[]`. Source review is not runtime confirmation. `guardlink report .` is not a substitute.
3. Generate `guardlink dashboard . --output .guardlink/threat-dashboard.html` and **open that
   exact file in the user's browser** using the host browser tool or OS opener. Inspect that
   the model and saved report are included. Without a browser, report the gap and path. Regenerate/reopen after model or report changes.

## Uncovered additions: public templates, news and durable delivery

After the initial review handoff, and at the chosen upkeep cadence, check cxg's public detection
templates separately from its pentest runtime. Record whether the collection exists before the
first template command (which may bootstrap it), then `cxg template pwd`, `cxg template list`,
and `cxg template update`. Record revision/time before and after; never force over local edits
or invent an unknown baseline. Network failure means stale/unknown freshness, not safety.
Search `cxg template search "<product or CVE>"`, inspect `cxg template info <id>` and the actual
code. Compare real versions, configuration, reach and prerequisites; do not execute all new
checks. Record applicability/evidence and unrun gaps in `security/template-applicability.md`.

For news/zero-days, verify dates and affected versions against primary advisories. If applicable
and no existing template covers it, **write a cxg test** through `bravos-templatize` /
`guardlink-translate` and cxg's language notes, then validate and run through the authorized
prove workflow. Annotate application claims first and complete the mandatory handoff. No target,
permission or oracle means ready-but-unrun/unsupported, never “safe”. Recurring news ingestion
needs a real host feed/scheduler integration; do not invent a Bravos news command.

Write redacted confirmed-finding summaries to the project's security folder: claim/source,
tested build, native evidence reference, impact, fix and retained regression-kit entry point.
Keep canonical bound kits where the installed skills require; do not copy raw secrets or
private authenticated traffic into tracked files. Preserve useful regressions after fixes.

End each flow with coverage, findings/controls under tested conditions, unresolved or unrun
items, template freshness and the actual report/dashboard/security-test locations. State which
MCP connections and ongoing hooks are active versus merely configured. Reports from
`bravos-report` complement the GuardLink STRIDE report; counts alone are not delivery.

Batch unavoidable host prompts into **one short final note**: restart the Claude Code session
that will use the new skills, Codex's one-time `/hooks` trust, and Gemini's folder trust, only
where applicable. Handle activation sign-in when it opens. Report any blocked setup command
separately under the blocked-step rule; execute all authorized, unblocked setup yourself.
