site/docs/**/*.md: Prioritize minimal edits when updating existing documentation; avoid creating entirely new sections or rewriting substantial portions; focus edits on improving grammar, spelling, clarity, fixing typos, and structural improvements where needed; do not modify existing headings (h1, h2, h3, etc.) as they are often linked externally.
Structure content to reveal information progressively: begin with essential actions and information, then provide deeper context as necessary; organize information from most important to least important.
Use action-oriented language: clearly outline actionable steps users should take, use concise and direct language, prefer active voice over passive voice, and use imperative mood for instructions.
Use 'eval' instead of 'evaluation' in all documentation; when referring to command line usage, use 'npx promptfoo eval' rather than 'npx promptfoo evaluation'; maintain consistency with this terminology across all examples, code blocks, and explanations.
The project name can be written as either 'Promptfoo' (capitalized) or 'promptfoo' (lowercase) depending on context: use 'Promptfoo' at the beginning of sentences or in headings, and 'promptfoo' in code examples, terminal commands, or when referring to the package name; be consistent with the chosen capitalization within each document or section.
Each markdown documentation file must include required front matter fields: 'title' (the page title shown in search results and browser tabs) and 'description' (a concise summary of the page content, ideally 150-160 characters).
Only add a title attribute to code blocks that represent complete, runnable files; do not add titles to code fragments, partial examples, or snippets that aren't meant to be used as standalone files; this applies to all code blocks regardless of language.
Use special comment directives to highlight specific lines in code blocks: 'highlight-next-line' highlights the line immediately after the comment, 'highligh...

In site/docs/red-team/strategies/free-agent.md around lines 36 to 46 (and also
apply the same change to lines 50 to 59), the YAML code fences include a title=

these fenced code blocks (or alternatively replace the partial snippets with a

🤖 Prompt for AI Agents
In src/redteam/providers/freeAgent.ts around lines 50-52 (and also apply same
changes in the block around 283-325), the FreeAgentResponse.metadata currently
references FreeAgentMetadata but that type lacks stopReason, messages, and
redteamFinalPrompt and uses an incompatible type for finding.severity; update
FreeAgentMetadata to declare stopReason: string | undefined, messages: Array<{
role: string; content: string }>| undefined, and redteamFinalPrompt: string |
undefined, change any finding.severity field type to the shared Severity type,
and when assigning severity normalize incoming strings by mapping/validating
them to the Severity enum (e.g., lowercase/trim and map to
Severity.Low/Medium/High/etc., with a safe default) before setting the
finding.severity. Ensure both the type additions and normalization logic are
applied in the response parsing code in the later block (lines ~283-325).

Sanitize logging: avoid embedding prompts/outputs and big objects
- Do not log raw context or goal via string interpolation (Line 130, 137).
- Truncate or drop content previews; log lengths/boolean flags only.
- Avoid logging full agent/target messages and rendered prompts (Lines 221-246, 431-448).
- Reduce unexpected response logs to metadata (Line 258) without payloads.
- Keep request logs free of sensitive content (Lines 359+, 377+).

In src/redteam/strategies/freeAgent.ts around lines 28-33 (and also apply same
fix to 43-51), guard against accessing testCase.vars![injectVar] directly by
using optional chaining and a safe fallback (e.g., const goal =
String(testCase.vars?.[injectVar] ?? '') or another appropriate default) so
missing vars don't throw; replace falsy checks that use || with nullish
coalescing (??) for defaults such as maxIterations (e.g., maxIterations =
providedValue ?? DEFAULT_ITERATIONS) or explicitly validate numeric values with
a > 0 check to avoid treating 0 as absent. Ensure similar protections are
applied to any other dereferences of testCase.vars and default assignments in
the indicated block.
