What is forge-security-review?

A guided security-review skill for Atlassian Forge apps. It examines the app’s code and configuration and produces evidence-based findings about security weaknesses.

Use it for Forge security audits, vulnerability assessments, penetration-test-style code reviews, authorization checks, web-trigger checks, and related investigations.

It helps find problems such as missing access checks, unsafe input handling, and weak tenant separation without loading every review rule unnecessarily.

About the project

Atlassian Forge Skills supports Atlassian Forge, a platform for building and deploying apps that extend products such as Jira and Confluence. Its skills and MCP-backed tools help coding agents create Forge apps, review them before deployment, optimize usage, troubleshoot failures, and work with Forge APIs and the Atlassian Design System.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

medium Prompt Injection · line 81
Large whitespace padding was detected (a block of blank lines or a long run of spaces). This can push injected instructions below or to the right of the visible area so a human reviewer never sees them while the agent still reads them. Manual review of the hidden content is recommended.

Fix: Remove the large whitespace padding (blank-line blocks or long space runs) and review any content hidden below or to the right of it. Keep skill files compact and reviewable so no instructions can be

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00074	$0.01441
Opus 5	$0.00037	$0.00720
Sonnet 5	$0.00015	$0.00288
Haiku 4.5	$0.00007	$0.00144

Security

Grade A, and why

forge-security-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/run_static_analysis.ps1, scripts/run_static_analysis.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 158 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Forge Security Review

Runs a Forge-focused white-box security review and reports validated findings with exploitability, impact, evidence, and remediation guidance.

Token-Efficient Default

Use manifest-driven routing by default to reduce token usage. Do not load every rule file up front.

Rule Assets

The review rules are packaged with this skill under assets/security-rules/:

Global baseline: assets/security-rules/_global-forge.mdc
Category indexes: assets/security-rules/forge-*/_index-*.mdc
Category deep checks: assets/security-rules/forge-*/*.mdc

Execution Mandate

When this skill is triggered:

Run static analysis first from this skill directory:

scripts/run_static_analysis.sh <forge-project-root-directory>
use .ps1 script for windows

Read manifest.yml first before any deep code review.
Load assets/security-rules/_global-forge.mdc first.
Load only relevant category index rules based on manifest and code signals.
Load deep subrules only when the matching detection heuristics are triggered by real code patterns.
Perform an evidence-based security review across:
- AuthN/AuthZ
- Injection and input validation
- Tenant isolation and cross-tenant leakage
- Secrets and storage
- Egress/remotes/CSP and manifest permissions
- Public entry points (web triggers)
- Agent and miscellaneous Forge security risks
Do not modify app code unless the user explicitly requests fixes.
Write all scan outputs and generated artifacts to security-audit-artifacts/.

Rule Routing Workflow

Phase 1: Reconnaissance (Mandatory)

Read manifest.yml first and extract:

permissions.scopes
permissions.external.fetch
permissions.content.scripts
modules (resolver/webtrigger/scheduledTrigger/rovo/etc.)
remotes
app.runtime.name

Build an execution map:

UI modules -> bridge calls -> resolvers/functions
External entry points (web triggers, events, schedules)
api.asUser() vs api.asApp() paths
Outbound fetch destinations

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
