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 | $0.00999 | $0.00999 |
| Opus 5.5 | $0.00400 | $0.00400 |
| Sonnet 5.5 | $0.00200 | $0.00200 |
| Haiku 4.5 | $0.00100 | $0.00100 |
Grade A, and why
code-meridian 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 15d 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 — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Short always-on guidance for automated agents working in this repository.
Read this first. Use the detailed references under docs/agent/ when the task needs more depth.
Behavior Expectations
- Do not assume silently. State important assumptions.
- If something is unclear, ask instead of guessing.
- Prefer the simplest solution that solves the request.
- Do not add speculative abstractions, flexibility, or features.
- Make surgical changes only. Avoid unrelated refactors.
- Match the existing style unless the task requires otherwise.
- Remove only unused code introduced by your own change unless asked.
- Define success criteria and verify them.
- For bugs, prefer reproduce -> fix -> verify.
- Every changed line should trace back to the request.
Required CodeMeridian Usage
Use CodeMeridian proactively. Prefer graph tools over terminal scans when the graph can answer the question.
Check get_project_profile(projectContext, targetPath?) before selecting language-specific edit tools. Markdown/text edits use document context and document_review; do not treat headings or filenames as callable symbols. Missing profiles and unaudited coverage remain unknown. PowerShell is detected but currently unsupported.
Trigger rules
| Situation | Tool to call |
|---|---|
| Before a non-trivial callable-code edit | build_minimal_context |
| Before a Markdown/text edit | get_project_profile, then search_documentation when document coverage is ready |
| Before editing a specific method/class | resolve_exact_symbol, then get_context_for_editing |
| Before a refactor | find_impact and find_test_shield |
| Before deleting code | find_unreferenced |
| Before starting a feature | analyze_feature_implementation_path, then find_implementation_surface for exact targets |
| Before trusting exact file targets | check_graph_freshness or find_graph_drift |
| "How do X and Y relate?" | find_connection |
| Frontend HTML/CSS/SCSS relationship work | build_minimal_context, then find_connection or find_implementation_surface |
| Before renaming or deleting a frontend class/selector/style import | find_impact |
| Investigating CSS/SCSS cascade or specificity issues | find_frontend_cascade_conflicts |
| Looking for repeated style values or token extraction candidates | find_duplicate_candidates |
| Looking for an existing implementation shape to mirror | find_implementation_patterns |
| Looking for duplicate/refactor risk | find_duplicate_candidates or find_similar_nodes |
| Looking for missing tests | find_coverage_gaps |
| Searching docs/decisions | search_documentation |
| Working with config | find_config_definitions and find_config_usage |
| Looking for keyword-related context | find_related_knowledge |
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.

code-meridian AGENTS.md is an instructions file published in the GitHub repository Driftya/code-meridian (5 stars, last pushed 6d ago), licensed MIT. It adds 999 tokens to every session, about $0.0040 per session on Opus 5.5. 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 2026-08-31.
