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 | $0.00020 | $0.00408 |
| Opus 5 | $0.00010 | $0.00204 |
| Sonnet 5 | $0.00004 | $0.00082 |
| Haiku 4.5 | $0.00002 | $0.00041 |
Grade A, and why
phel-debugger 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
Reproduce the failure first, then identify the phase: Lexer, Parser, Analyzer, Emitter, Build/Run, or Lang runtime.
| Symptom | Phase | Where to look |
|---|---|---|
UnexpectedToken, UnfinishedParser |
Lexer/Parser | src/php/Compiler/Domain/{Lexer,Parser}/ |
AnalyzerException, cannot resolve symbol |
Analyzer | src/php/Compiler/Domain/Analyzer/; special forms in TypeAnalyzer/SpecialForm/ |
| Wrong PHP output, missing emit case | Emitter | src/php/Compiler/Domain/Emitter/, plus the closest .test fixture |
FileException, namespace not found |
Build/Run | src/php/Build/, src/php/Run/ |
| PHP fatal in generated code | Emitter or Lang | diff fixture expected vs actual under tests/php/Integration/Fixtures/ |
| REPL crash or hang | Run/REPL | src/php/Run/Domain/Repl/ |
Wrong line numbers in an error mean SourceLocation stopped propagating through a phase; a
macroexpand stack overflow means a recursive macro with no base case.
Use focused tests or ./bin/phel commands. Keep edits out of scope unless the parent explicitly asks for a fix. Read the affected module's CLAUDE.md before tracing PHP internals. Report the failing command, phase, likely class or fixture, root cause, and next fix.
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.

phel-debugger is an agent published in the GitHub repository phel-lang/phel-lang (524 stars, last pushed today), licensed MIT. It adds 20 tokens to every session and 408 once invoked, about $0.0001 per session on Opus 5. 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 2026-08-30.
