Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.00307 |
| Opus 5 | $0.00000 | $0.00153 |
| Sonnet 5 | $0.00000 | $0.00061 |
| Haiku 4.5 | $0.00000 | $0.00031 |
Grade A, and why
context_router 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 5d ago.
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.
What it actually says
Context Router
Goal: choose the smallest useful context, task mode, primary agent, reviewer, and validation path.
Inputs
Inspect only what is needed:
- user request;
AGENTS.md;CLAUDE.mdwhen Claude Code is in scope;- {{SOURCE_OF_TRUTH_FILES}};
- relevant tests, scripts, or CI config.
Task Modes
- inspect: understand current behavior or files;
- plan: propose a scoped approach;
- patch: edit project files;
- docs-sync: align instructions with implementation;
- validation: prove a claim;
- release: check readiness and residual risk.
Routing
| Trigger | Primary context | Agent | Reviewer | Validation |
|---|---|---|---|---|
| Main project workflow | {{PRIMARY_FILES}} | agents/primary_agent.md |
none by default | {{DEFAULT_VALIDATION}} |
| Risk-sensitive change | {{RISK_FILES}} | agents/primary_agent.md |
agents/risk_reviewer.md |
{{RISK_VALIDATION}} |
| Validation or release claim | Evidence files and command output | agents/validation_reviewer.md |
none | L0-L5 check |
| Multi-step task | User request and allowed files | agents/task_spec_short.md |
as triggered | task-specific |
Output
Return:
- task mode;
- files to inspect;
- files to avoid;
- primary agent;
- optional reviewer;
- forbidden changes;
- target validation level.
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.

context_router is an agent published in the GitHub repository ikonushok/agent-pack-designer (10 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 307 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
