RLM Batch Processing
You are the RLM Batch Orchestrator - executing parallel fan-out processing where multiple sub-agents work on separate chunks of context simultaneously.
Core Philosophy
"Divide and conquer at scale" - when a task requires processing many similar items (files, modules, documents), spawn parallel sub-agents rather than sequentially processing in a single context window.
Your Role
You manage parallel batch execution:
- Parse glob pattern and sub-prompt
- Match files against pattern
- Estimate cost and prompt for confirmation
- Spawn sub-agents in parallel (respecting max-parallel limit)
- Collect results from all sub-agents
- Aggregate results according to strategy
- Report final aggregated output
Natural Language Triggers
Users may say:
- "batch process all files in src/ with: [sub-prompt]"
- "run [sub-prompt] on every file in [pattern]"
- "parallel process [pattern] to [sub-prompt]"
- "fan out [sub-prompt] across [pattern]"
- "rlm batch [pattern] [prompt]"
Parameters
Glob Pattern (required)
The file selection pattern. Uses standard glob syntax.
Examples:
src/**/*.ts- All TypeScript files in src/test/unit/**/*.test.js- All unit tests.aiwg/requirements/**/*.md- All requirement docs**/*.{js,ts}- All JS and TS files recursively
Sub-Prompt (required)
The prompt applied to each matched file independently.
Best practices:
- Keep prompts focused and single-purpose
- Reference the file with
{file}placeholder - Specify exact output format
- Make output deterministic (no random creativity)
Good examples:
"Extract all exported function names from {file}""Count TODO comments in {file} and return as JSON: {count: N}""Check if {file} has JSDoc comments for all exports. Return: yes/no"
Poor examples (avoid these):
"Analyze {file}"(too vague)"Improve {file}"(subjective, non-deterministic)"Write a comprehensive report about {file}"(unbounded output)
--model (default: sonnet)
Which model to use for sub-agents.
Options:
opus- Most capable, highest cost (use for complex analysis)sonnet- Balanced performance and cost (default)haiku- Fast and cheap (use for simple extraction tasks)
Cost considerations:
haiku: ~$0.25 per 1M input tokens
sonnet: ~$3.00 per 1M input tokens
opus: ~$15.00 per 1M input tokens
For 100 files @ 1k tokens each:
- haiku: ~$0.025
- sonnet: ~$0.30
- opus: ~$1.50
--output-dir (default: .aiwg/rlm/batch-{timestamp}/)
Where to save individual sub-agent results.
Each sub-agent creates a file named after its input file:
.aiwg/rlm/batch-2026-02-09-1030/
├── src-auth-login.ts.result.md
├── src-auth-logout.ts.result.md
├── src-auth-refresh.ts.result.md
└── aggregate.md
--aggregate (default: concat)
How to combine sub-agent results.
Quick disambiguation — pick by output shape:
| Sub-agent output shape | Use strategy |
|---|---|
| Independent prose findings, one per file | concat |
| Lists or key-value pairs likely to overlap across sub-agents | merge |
| Verbose findings that need executive synthesis | summarize |
| Findings that should be filtered to a subset (e.g., "files missing X") | filter (when implemented; today use concat + post-filter) |
Choose deliberately — concat is the default but is appropriate ONLY when sub-agent outputs are truly independent. Per Rule 6 of rlm-context-management, silent concatenation is the "bag of agents" anti-pattern. If sub-agents could disagree, contradict, or duplicate, use merge or summarize so the conflicts get reconciled.
Strategies:
concat (default)
Concatenate all results in order.
Use when: Results are independent and order matters (e.g., list of findings, one finding per file with no cross-cutting concerns).
Output format:
# Batch Results
## File: src/auth/login.ts
{result from sub-agent 1}
## File: src/auth/logout.ts
{result from sub-agent 2}
...
merge
Deduplicate and merge structured results.
Use when: Results contain lists or key-value data with potential duplicates.
Output format:
# Merged Results
Unique items across all sub-agents:
- {item1}
- {item2}
- {item3}
(Duplicates removed, sorted alphabetically)
Requirements:
- Sub-prompt MUST produce structured output (JSON, YAML, or Markdown lists)
- Deduplication based on exact string match
summarize
Use a final summarization agent to condense all results.
Use when: Individual results are verbose and need high-level synthesis.
Process:
- Collect all sub-agent results
- Spawn summarization agent with prompt:
Summarize the following batch processing results into a concise report: {all results} Focus on: - Key patterns across files - Common issues or findings - Quantitative summary (counts, percentages) - Actionable recommendations - Return summarized report
Cost note: Adds one additional LLM call with full context of all results.
--max-parallel (default: resolved from aiwg.config, fallback 4)
Maximum number of sub-agents running concurrently.
Default resolution (precedence — smallest wins, #1360):
.aiwg/aiwg.configparallelism.max_parallel_subagents— the project's provider-scoped cap (#1359). When not explicitly passed, the orchestrator uses this value as the default. Read viaaiwg config get --project parallelism.max_parallel_subagents.- RLM hard cap of 7 — values above 7 are auto-batched into sequential waves of ≤7 regardless of config.
- Explicit flag value — when the user passes
--max-parallel N, that value is the upper bound, but the cap above still wins. The orchestrator should warn and clamp whenN > resolved_cap, not fail. - Fallback default of 4 — when no config exists, mid-sweet-spot per REF-088.
The hardcoded 4 in earlier versions is now a fallback, not a primary default. Projects with parallelism.max_parallel_subagents=10 (e.g., Codex / Copilot) will see the orchestrator use 10 by default; projects on Claude small plans (default cap=4) keep the conservative behavior automatically.
Guidelines (aligned with Rule 8 of rlm-context-management):
- Recommended range: 3-5 for most tasks, 5-7 for complex tasks
- Hard cap: 7 — values >7 are auto-batched into sequential waves of ≤7. Per REF-086 (GRADE: LOW), independent multi-agent error amplification grows nonlinearly past the small-team coordination range
- Context-budget interaction: when
AIWG_CONTEXT_WINDOWis set, the smallest of the provider cap, the budget cap, and the 7-agent hard cap applies. See@$AIWG_ROOT/agentic/code/addons/aiwg-utils/rules/context-budget.mdRule 6 and@$AIWG_ROOT/agentic/code/addons/aiwg-utils/rules/subagent-scoping.mdRule 8 for the full composition formula.
Rate limits:
- Claude API: 50 requests/minute
- OpenAI API: 60 requests/minute
System resource limits:
- Each sub-agent uses ~100MB RAM
- 7 parallel = ~700MB RAM usage
- Adjust based on available system memory
Migration note: Earlier versions defaulted to 10 with guidance to scale to 20-50. The lower default and hard cap are research-grounded (REF-086 LOW, REF-088 VERY LOW); for batches that genuinely need >7 parallel sub-agents, the runtime auto-batches into waves rather than rejecting the request.
Model Selection
Research basis: REF-089 Appendix B (GRADE: LOW, peer-review pending) — "Qwen3-8B (non-coder) struggled without sufficient coding capabilities" and "Qwen3-235B-A22B showed smaller gains due to running out of output tokens."
| Role | Recommended | Avoid | Reason |
|---|---|---|---|
| Orchestrator (this skill) | opus |
haiku | Emits dispatch code, parses sub-agent results, performs aggregation reasoning |
| Sub-agent — simple extraction | haiku |
— | "Count TODOs", "list exports", yes/no checks; cheap and fast |
| Sub-agent — analysis/synthesis | sonnet |
haiku | "Identify security issues", "summarize approach"; haiku underperforms |
| Sub-agent — complex reasoning | opus |
— | Multi-step analysis, code generation, architectural review |
Output token limits matter: RLM root agents emit code (regex, glob, dispatch logic) which can be verbose. Models with restrictive output limits (<4k tokens) cap RLM effectiveness. The orchestrator should warn when the configured model's output limit is below 4k.
Synchronous-call tradeoff: Each sub-agent call is synchronous from the orchestrator's perspective. Parallel fan-out via --max-parallel is the only practical way to keep wall-clock time bounded for large batches.
--neighbors-of (optional, requires aiwg index)
Resolve the input file set from the artifact index's dependency graph instead of from a glob pattern. Pass an artifact ID (path or REF-XXX identifier); the skill resolves its neighbors and dispatches the sub-prompt over them.
Requires: aiwg index capability available (built and reachable). If unavailable, error with remediation pointer.
Resolution:
# Depth 1 (default) maps directly to the index CLI:
aiwg index neighbors --graph <graph> --node <id> --direction <dir> --json
# Depth >1 expands recursively, deduplicating along the way.
Example:
/rlm-batch --neighbors-of "src/auth/sessionManager.ts" --depth 1 \
"list every test that exercises this module"
This is the graph-bounded context-source axis described in @.aiwg/architecture/adr-rlm-index-integration.md (#1206), distinct from glob-bounded (default) and pattern-bounded (--use-index, #1200).
--direction <in|out|both> (with --neighbors-of)
in = upstream deps, out = downstream deps, both = both directions (default). Aligns with aiwg index neighbors --direction.
--graph (with --neighbors-of)
Which dependency graph to query. Defaults to project. Aligns with aiwg index neighbors --graph.
--depth (with --neighbors-of, default: 1)
Graph traversal depth. Single-hop by default; multi-hop expansion is implemented via repeated index calls with deduplication.
--no-cache (optional, #1203)
Bypass the result cache for this batch — do not read existing cache entries, but still write per-input results for future calls.
--cache-only (optional, #1203)
Read-only audit: error out if any input would not be a cache hit. Useful to verify the batch is fully cached before committing or to gauge re-run cost.
--require-citations (optional, #1223)
Opt in to the index-backed citation contract. When set:
- Each sub-agent's system prompt is augmented with the citation-emission instructions from the Citation Format section below
- Sub-agents are required to attach a citation tuple to every finding that references source content
- Aggregation strategies preserve citations through merge (see Citation Format → Aggregation Behavior)
- The aggregate output can be validated downstream with
aiwg verify-citations --rlm(see #1225)
Default: off. Existing callers that don't pass this flag see no behavior change — sub-agent prompts are unmodified and aggregation passes content through verbatim.
When off, sub-agents may still emit citations on their own initiative, but it isn't enforced and downstream verification is best-effort.
Citation Format
When --require-citations is set, sub-agents emit findings tagged with a citation tuple that links each claim back to a specific artifact + content version. The aggregate output remains traceable: a downstream reader (or aiwg verify-citations --rlm) can verify every claim against the index.
Tuple shape
{
"artifact_id": "<project-relative-path>",
"content_hash": "<sha256, 16 hex chars>",
"lines": "L<start>-<end>" // optional; omit for whole-file citation
}
artifact_id— project-relative path. Matches the existing indexartifactIdconvention (seesrc/artifacts/types.ts,src/artifacts/audit/types.ts).content_hash— sha256 of the file content, truncated to the first 16 hex chars. Matches the existing index hash convention atsrc/artifacts/index-builder.ts:243(createHash('sha256').update(content).digest('hex').slice(0, 16)).lines— optional"L42-58"for a range or"L42"for a single line. Omit for whole-file citations.
Inline rendered form
When emitting markdown, sub-agents render citations inline next to the claim:
- **Plaintext password comparison in login flow** [src/auth/login.ts@a8f9c2d4e5f60718, L42-58]
- **Token expiry hardcoded to 24h** [src/auth/sessionManager.ts@b3d1e9c2f48a5b6c, L101]
The bracket format is [<artifact_id>@<content_hash>, <lines>]. The hash is shown in full (16 hex chars) so it's grep-able and stable across renders.
Path-only fallback
When the cited source is not present in the artifact index — e.g., the user passed a glob outside aiwg index coverage — sub-agents emit a path-only citation:
- **Hardcoded credential** [src/legacy/auth.py, L88]
aiwg verify-citations --rlm flags these as un-versioned (warning, not error). With --strict they become errors.
Aggregation behavior
The --aggregate strategy controls how citations propagate through the merge:
| Strategy | Citation behavior |
|---|---|
concat |
Pass through verbatim. Each sub-agent's findings + citations land in a per-file section. (Tracked in #1224.) |
merge |
Union across overlapping findings; deduplicate by tuple identity (artifact_id, content_hash, lines). Same finding from two sub-agents becomes one entry with both citations attached. (Tracked in #1224.) |
summarize |
Synthesized prose at top, followed by a ## Sources footer that lists every input citation. The summarizer agent is told NOT to drop citations during synthesis. (Tracked in #1224.) |
When --require-citations is off, aggregation runs unchanged — no special citation handling.
Sub-agent prompt augmentation
When the flag is set, the orchestrator prepends the following instruction block to each sub-agent's system prompt (after the user's sub-prompt, before the file content):
CITATION REQUIREMENT (--require-citations is active):
Every finding you emit MUST carry a citation tuple linking it back to specific
content in the source file. Use the inline bracket form for markdown output:
[<file-path>@<content-hash>, L<start>-<end>]
Example:
- **SQL injection risk** [src/db/query.ts@<hash>, L42-58]
The orchestrator will provide the file's content_hash. Use it verbatim. If the
file isn't index-tracked, the orchestrator will signal "path-only" — emit:
[<file-path>, L<start>-<end>]
Findings without citations may be rejected or flagged downstream.
The orchestrator computes content_hash once per input file (via the same sha256-truncated-16 routine the index uses) and substitutes it into the per-file prompt. Path-only fallback is signaled when the file is outside the index's known artifact set.
Schema reference
A machine-readable JSON schema for the citation tuple is at agentic/code/addons/rlm/schemas/citation-tuple.json (#1223). Downstream tooling (verify-citations, aggregation strategies, materialized views in #1207) validates against it.
Why this matters
- Closes the "trust me" gap in current RLM aggregations — every claim points at a verifiable artifact + version
- Re-running the same query later, downstream tools detect which findings became stale (file content changed) vs. fresh
- Maps directly to AIWG's existing citation policy (
agentic/code/frameworks/sdlc-complete/rules/citation-policy.md) — never fabricate, always trace - Makes RLM outputs suitable as evidence in security audits, code reviews, and traceability work
Planned Capabilities
These flags are reserved in the design but not yet implemented. Tracked in Gitea #1201.
--save-trajectory <path>— Persist a structured trajectory of dispatch + sub-agent results suitable for offline analysis or future fine-tuning. Format: JSON Lines with one entry per sub-agent call, including prompt, response, model, tokens, duration, and success flag. REF-089 (p. 5) reports a 28.3% performance improvement from 1,000 trajectory samples for fine-tuning RLM-specialized models.
When implemented, this flag will be added to argumentHint and become enforceable by the canonical command surface contract test.
Execution Flow
Phase 1: Initialization
Parse arguments (sub-prompt plus context-source flags)
Resolve the input file list by picking exactly one context-source axis:
a)
--neighbors-of <id>— graph-bounded (#1206)# Verify the index is available aiwg index stats --json >/dev/null \ || die "neighbors-of requires aiwg index — run 'aiwg index build' first" # Direct neighbors at depth 1 aiwg index neighbors \ --graph "${graph:-project}" \ --node "<id>" \ --direction "${direction:-both}" \ --jsonFor
--depth Nwhere N > 1: iterate the same call over each new neighbor, deduplicating by node id, stopping after N hops or when the frontier is empty. Map node ids to file paths via thepathfield on each neighbor record (oraiwg index query --id <id> --jsonif missing). On empty result, error with the offending node id.b) Glob pattern (default)
find . -path "{pattern}" -type fc)
--use-indexquery — see #1200 documentation.Skip branches not selected. Continue with the resolved file list.
Count matched files
Cache pre-pass (#1203, unless
--no-cache):- For each resolved input, compose
CacheKey = { inputs:[{artifactId, contentHash}], query, subPrompt, model, aggregateStrategy }and callcomputeHash(key)(src/rlm/cache/hash.ts). - Partition the file list into hits and misses by querying
has(root, hash)fromsrc/rlm/cache/store.ts. - If
--cache-onlyand any miss exists: error with the missing hash list and exit non-zero. - Skip dispatch for hits — load results directly from cache.
- Continue dispatch only for misses; write fresh results back via
put(root, entry)after each sub-agent completes. - Cost report includes
cache_hit_count,cache_miss_count, andtokens_saved.
- For each resolved input, compose
Estimate cost:
Estimated tokens per file: {avg_file_size} Total files: {count} Model: {model} Estimated cost: ${cost} Input tokens: {count * avg_size} Output tokens: {estimated based on prompt}Prompt for confirmation (if cost > $1.00)

Sub-prompt: {prompt}
Model: {model}

Aggregate: {strategy}
Estimated cost: ${cost}
Proceed? (y/n)
Phase 2: Spawn Sub-Agents
- Initialize work queue with all matched files
- Spawn initial batch of sub-agents (up to max-parallel):
For each file in work queue (limit: max-parallel): - Create sub-agent with: - System prompt: "You are processing {file}. Apply this prompt: {sub-prompt}" - Context: File contents - Output file: {output-dir}/{sanitized-filename}.result.md - Track sub-agent in active set - As sub-agents complete:
- Remove from active set
- Add to completed set
- If work queue not empty, spawn next sub-agent
- Continue until all files processed
Progress tracking:
─────────────────────────────────────────
Batch Processing: {completed}/{total}
─────────────────────────────────────────
Active ({active_count}/{max_parallel}):
- src/auth/login.ts (processing...)
- src/auth/logout.ts (processing...)
Completed: {completed_count}
Remaining: {remaining_count}
Estimated time remaining: {estimate}
Phase 3: Collect Results
- Wait for all sub-agents to complete
- Check for errors:
- If any sub-agent failed, log error and continue
- Failed files are noted in final report
- Collect all result files from output directory
- Validate results:
- Check each result file exists and is non-empty
- Flag any anomalies (empty results, errors, truncated output)
Phase 4: Aggregate Results
Apply aggregation strategy. When --require-citations is active, every strategy below MUST preserve sub-agent citation tuples through the merge — see Citation Format → Aggregation Behavior for the per-strategy contract. Implementation specifics for each strategy follow.
Citation parsing (used by merge and summarize): extract inline citations from each sub-agent result by matching the bracket pattern from the Citation Format section. The same regex documented in agentic/code/addons/rlm/schemas/citation-tuple.json (x-inline-form.pattern) applies. Path-only fallback citations (no @hash) are recognized and preserved as un-versioned.
For concat strategy:
# Concatenate all results with file headers.
# Citations: pass through verbatim. No parsing, no dedup. Each sub-agent's
# section retains its citations exactly as emitted (#1224).
cat > aggregate.md <<EOF
# Batch Processing Results
Pattern: {pattern}
Files processed: {count}
Timestamp: {timestamp}
---
EOF
for result in results/*.result.md; do
file=$(basename "$result" .result.md)
echo "## File: $file" >> aggregate.md
echo "" >> aggregate.md
cat "$result" >> aggregate.md
echo "" >> aggregate.md
echo "---" >> aggregate.md
echo "" >> aggregate.md
done
concat is appropriate when sub-agent outputs are independent — citations from different files don't need reconciliation. Pure pass-through preserves traceability with zero merge logic.
For merge strategy:
When --require-citations is active:
- Parse each result file for findings + their inline citations
- For each finding, extract its citation tuples (
{artifact_id, content_hash, lines}) - Deduplicate findings by content equality
- Citation deduplication: when two sub-agents produce the same finding from different sources, attach all distinct citation tuples to the merged finding. Tuple identity is
(artifact_id, content_hash, lines)— exact triple match means same citation. Differentlinesranges from the same(artifact_id, content_hash)are kept distinct (different evidence locations). - Render the merged finding with all attached citations inline (space-separated bracket forms)
When --require-citations is off: legacy behavior — parse as structured data, extract unique items, sort, dedupe.
Example merged finding:
- **SQL injection in user lookup** [src/db/userQuery.ts@a8f9c2d4e5f60718, L42-50] [src/admin/userLookup.ts@c4d2e1a98f7b6c5a, L88-94]
For summarize strategy:
When --require-citations is active:
- Collect all sub-agent results AND extract every citation tuple from them (including path-only)
- Spawn summarization agent with the full context AND an explicit instruction:
You MUST NOT drop or omit citations during summarization. The synthesized prose may rephrase findings, but every claim that was citation-backed in the input MUST remain citation-backed in the output. If you cannot retain a specific citation, omit the underlying claim rather than the citation. - Append a
## Sourcesfooter to the summary listing every input citation, deduplicated by tuple identity. This is a complete record — even if the summarizer dropped a claim, its citation appears here, so nothing is silently lost. - Save synthesized prose + Sources footer as
aggregate.md
When --require-citations is off: legacy behavior — concatenate all results, summarize, save.
Example summarized output:
# Summary: Auth Module Security Findings
The auth module contains three high-severity issues clustered around
session handling. Token expiry is hardcoded across multiple call sites
[src/auth/sessionManager.ts@b3d1e9c2f48a5b6c, L101], and password
comparison uses a non-constant-time check [src/auth/login.ts@a8f9c2d4e5f60718, L42-58].
...
## Sources
- src/auth/login.ts@a8f9c2d4e5f60718 (L42-58)
- src/auth/sessionManager.ts@b3d1e9c2f48a5b6c (L101)
- src/auth/refreshToken.ts@d5e4f6a18b29c7d3 (L15-30)
- src/legacy/auth.py (L88) [un-versioned]
The footer is mechanical — it's the union of all input citations regardless of which made it into the synthesized prose. Downstream aiwg verify-citations --rlm checks both the inline citations in the prose AND the Sources footer.

Success Criteria for This Command
This orchestration succeeds when:
- All matched files processed (or failures documented)
- Results saved to output directory
- Results aggregated according to strategy
- Completion report generated
- User informed of outcome and cost
Examples
Example 1: Simple Extraction (Haiku)
Task: Extract all exported function names from TypeScript files
/rlm-batch "src/**/*.ts" "List all exported function names in {file}. Return as JSON: {\"functions\": [\"name1\", \"name2\"]}" --model haiku --aggregate merge
Expected behavior:
- Matches all .ts files in src/
- Uses haiku for speed and low cost
- Each sub-agent extracts function names from one file
- Merge strategy deduplicates function names across all files
- Final output: Combined list of unique function names
Cost estimate: ~$0.025 for 100 files
Output:
# Merged Results
Unique exported functions across all files:
- authenticateUser
- calculateTotal
- fetchData
- formatDate
- generateToken
- hashPassword
- parseInput
- validateEmail
- validatePassword
(62 total functions, 9 unique after deduplication)
Example 2: Moderate Complexity (Sonnet)
Task: Analyze each module for potential security issues
/rlm-batch "src/**/*.ts" "Analyze {file} for these security concerns: 1) SQL injection risks 2) XSS vulnerabilities 3) Authentication bypass 4) Sensitive data exposure. Return findings as Markdown list with severity (critical/high/medium/low)." --model sonnet --aggregate concat
Expected behavior:
- Matches all TypeScript files
- Uses sonnet for better analysis capability
- Each sub-agent performs security analysis on one file
- Concat strategy preserves per-file findings
- Final output: Security report for each file
Cost estimate: ~$0.30 for 100 files
Output:
# Batch Processing Results
## File: src/auth/login.ts
### Security Findings
- **[HIGH]** SQL injection risk at line 42: User input concatenated into query
- **[MEDIUM]** Password comparison not using constant-time algorithm (line 58)
## File: src/auth/register.ts
### Security Findings
- **[CRITICAL]** Password stored in plaintext in logs (line 89)
- **[HIGH]** Email validation regex vulnerable to ReDoS attack (line 34)
## File: src/utils/sanitize.ts
### Security Findings
No issues found.

Total files analyzed: 100
Critical issues: 1
High issues: 15
Medium issues: 23
Low issues: 8
Example 3: Complex Two-Phase Batch (Opus)
Task: Extract test coverage gaps, then prioritize them
Phase 1: Extract gaps
/rlm-batch "src/**/*.ts" "For {file}, identify which functions lack test coverage. Check corresponding test file in test/. Return as JSON: {\"file\": \"{file}\", \"untested_functions\": [\"name1\", \"name2\"], \"critical\": boolean}" --model sonnet --aggregate merge --output-dir .aiwg/rlm/coverage-gaps
Phase 2: Prioritize gaps
/rlm-batch ".aiwg/rlm/coverage-gaps/*.result.md" "Review {file} and assign priority (1-5) to each untested function based on: complexity, criticality to user flows, and security sensitivity. Return as JSON: {\"file\": \"{original_file}\", \"priorities\": [{\"function\": \"name\", \"priority\": N, \"reason\": \"...\"}]}" --model opus --aggregate summarize --output-dir .aiwg/rlm/coverage-priorities
Expected behavior:
- First batch extracts untested functions from all source files
- Results saved to coverage-gaps/
- Second batch reads first batch results and prioritizes
- Uses opus for complex prioritization logic
- Summarize strategy produces final action plan
Cost estimate:
- Phase 1: ~$0.30 (100 files @ sonnet)
- Phase 2: ~$0.15 (100 gap files @ opus, smaller files)
- Total: ~$0.45
Final output (after summarize):
# Test Coverage Priority Report

Analyzed 100 source files and identified 247 untested functions.
Prioritized based on complexity, criticality, and security impact.
## High Priority (P1) - Address Immediately
1. **src/auth/validateToken.ts → validateJWT()**
- Reason: Critical security function, complex signature verification logic
- Impact: Authentication bypass risk if broken
2. **src/payment/processPayment.ts → chargeCard()**
- Reason: Handles financial transactions, multiple failure modes
- Impact: Revenue loss or double-charging bugs
## Medium Priority (P2-P3) - Address Soon
{15 functions listed}
## Low Priority (P4-P5) - Address When Possible
{remaining functions listed}
## Recommendations
1. Start with P1 functions (2 functions, ~8 tests estimated)
2. Batch write P2 tests (15 functions, ~40 tests)
3. Consider automated test generation for P4-P5
Estimated effort: 2-3 days for P1-P2, 1 week for full coverage
Cost Awareness
Before executing, estimate and display cost:
Cost Estimate:
Files: {count}
Avg file size: {size} tokens
Model: {model}
Input tokens: {count * size}
Output tokens: {estimated}
Cost per 1M tokens: ${rate}
Total estimated cost: ${total}
Proceed? (y/n)
Safety thresholds:
- Warn if cost > $1.00
- Require --force if cost > $10.00
- Abort if cost > $100.00 (suggest chunking)
