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 | $0.01153 | $0.01153 |
| Opus 5.5 | $0.00461 | $0.00461 |
| Sonnet 5.5 | $0.00231 | $0.00231 |
| Haiku 4.5 | $0.00115 | $0.00115 |
Grade A, and why
AI4L AGENTS.md 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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project Instructions
Session related
- For interactive conversations, follow "prompts/PERSONA.md"
Glossary
-
"ER" stands for evidence review
-
"_ER.md" refers to the .md file of an ER
-
"ER.md" refers to the ER prompt ([er_prompt]), never to an ER file
-
"QA" stands for quality assurance; a "QA audit" is the audit of an ER against ER.md
-
"_ER_QA.md" refers to the .md file of a QA of an ER
Timestamps
- When generating timestamps (for filenames, headers, etc.), always obtain the current date/time by running
datein the shell. Never use the model's internal clock, as it may differ from the local timezone.
Globals for Skills and @Agents
-
[er_prompt] = "prompts/ER.md"
-
[creation_dir] = "creation/"
-
[tmp_dir] = "creation/tmp/"
-
[trash_dir] = "creation/trash/"
-
[library_dir] = "library/"
-
[max_audits] = 20
-
[needed_passes] = 1
Hard Rule
- NEVER modify any files outside of [creation_dir], [tmp_dir], or [trash_dir] without explicit user permission. This includes, but is not limited to, files in the root directory, configuration files, and any other files not in the listed directories.
When Calling @Agents
- ALWAYS call the @agent exactly as specified in the prompt
- DO NOT modify the prompts for the @agent or the way to call them; pass the prompt as it is.
- DO NOT modify the arguments you pass to the @agent; pass them as they are.
MCP Servers
When calling d-pubmed (pubmed_fetch_articles), always pass 'pmids' as a proper JSON array of strings, never as a comma-separated string or single value
When verifying PubMed URLs, use mcp__d-pubmed__pubmed_fetch_articles first. If the PMID resolves, that is the verification; only if it does not resolve, fall back to the chain below.
When verifying ClinicalTrials.gov URLs, use mcp__d-clinicaltrialsgov__clinicaltrials_get_study_record first. If the NCT ID resolves, that is the verification; only if it does not resolve, fall back to the chain below.
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.
