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 | $0.00422 | $0.00422 |
| Opus 5.5 | $0.00169 | $0.00169 |
| Sonnet 5.5 | $0.00084 | $0.00084 |
| Haiku 4.5 | $0.00042 | $0.00042 |
Grade A, and why
appicon 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 1mo 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 — 36 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent guidance
The project constitution is .specify/memory/constitution.md. Read it, then use docs/README.md to locate the contract relevant to the change.
- Resolution is cache-first. Warm-cache and test paths must not contact live
providers; use fixtures or
httptest. - Preserve the consumer contract: local paths, exit
1as a supported miss, stable JSON schemas, and caller fallback glyphs. MCP stays a thin wrapper over the shared resolver. - Treat remote indexes, archives, paths, and install destinations as hostile. Preserve allowlists, containment, extraction limits, and safe wipe bounds.
- Store only secret environment-variable names in configuration. Never expose
credential values; missing credentials skip a stage as
stage(auth). - Keep daemon use optional and all CLI operations functional in-process.
- Update the source-of-truth docs and synchronized schemas/contracts together.
- Run focused tests, then
make check-fast; usemake checkfor release-bound or cross-cutting work. Report skipped tools instead of claiming they passed.
Planning and evidence
Use the project guide and constitution for substantial changes. The guide owns Spec Kit scope, retained history, retrospective requirements, and acceptance evidence. Prose maintenance uses the normal repository workflow.
Context and handoffs
- Search before reading. Use bounded source excerpts for exploratory reads over 350 lines, and inspect required guidance and actual source before editing.
- When delegation is permitted, assign a bounded question or output, paths, and check. Return source locations, changes, and verification gaps for final review.
- Keep durable corrections in the project guide or owning contract. Replace superseded advice and read it before reuse. Temporary progress belongs in task notes. Preserve existing authority rules.
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.

appicon AGENTS.md is an instructions file published in the GitHub repository bolens/appicon (1 stars, last pushed 2d ago), licensed MIT. It adds 422 tokens to every session, about $0.0017 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.
