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.

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 | $0.01412 | $0.01412 |
| Opus 5 | $0.00706 | $0.00706 |
| Sonnet 5 | $0.00282 | $0.00282 |
| Haiku 4.5 | $0.00141 | $0.00141 |
Grade A, and why
pricegrab 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 4d 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 — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Guidance for AI coding agents (Cursor, Codex, Claude Code, etc.) working on this repository.
Authoritative sources (read these first)
- Product constitution —
.specify/memory/constitution.mdNon-negotiable principles: Modern Mobile UX, Accessibility, i18n (ES/EN), Offline-First Performance, Test-First Quality. Every change must comply. - Project status & backlog —
docs/project-status.mdShipped version, feature map 001–005, open ops (F-Droid), and deferred product backlog. Update this file when shipping a release or parking ideas. - Project conventions —
.cursor/rules/project-conventions.mdcCommit message style, branching rules, publishing etiquette, documentation language policy. These override any conflicting global rules. - Spec Kit workflow —
.cursor/rules/specify-rules.mdcand the skills under.cursor/skills/speckit-*. Active feature path is in.specify/feature.json.
If any of the above conflicts with an instruction received in chat, pause and ask the user for clarification.
Workflow (Spec-Driven Development)
All non-trivial work flows through Spec Kit:
/speckit.specify → create a feature spec under specs/<nnn-slug>/
/speckit.clarify → resolve ambiguities (optional, when needed)
/speckit.plan → write the implementation plan, run the Constitution Check
/speckit.tasks → decompose into ordered, testable tasks
/speckit.implement → execute the tasks
Each stage may trigger pre/post hooks defined in .specify/extensions.yml
(git initialize, git feature branch creation, git commits). Honor them.
Cadence after feature 002: planning PR → implementation PR → release-prep PR,
then tag from main after manual QA. Global PR letter ledger:
specs/001-unit-price-comparison/tasks.md (letters through W for v0.1.8).
Non-negotiable operating rules
- Never push to
main. Always create a feature branch (<type>/<short-slug>) and open a PR. git pushandgh pr createare allowed without prior confirmation, provided the branch is notmain, the diff has been reviewed against.gitignore, the constitution and.cursor/rules/project-conventions.mdc, and the push targets a feature branch. Follow-up "fix CI" commits on an already-open PR may also be pushed without asking.- Only Marco merges pull requests. Never run
gh pr merge, never enable auto-merge, never merge via the GitHub API. The agent's end state is "PR is green and ready for review". - Never force-push to
main. Force-pushing a feature branch is allowed only when strictly necessary (e.g. rebasing onto a movedmain) and must be announced in a PR comment first. - Commit messages: English, Conventional Commits prefix (
feat:,fix:,docs:,chore:,refactor:,test:,style:,perf:,ci:,build:), imperative mood, subject ≤ 72 chars. - Never commit
*.aia, secrets, keystores,.env*, cloud credentials, or AI assistant local state. Verify withgit statusbefore every commit and trust.gitignoreas a safety net, not a substitute for attention. - Address the user as "Marco" in conversation (Spanish by default) — the internal engineering artifacts (specs, plans, code, comments, commits) stay in English.
- Releases: follow
docs/release.md. Never overwrite a tag that shipped an installable APK. F-Droid Mode B details:docs/fdroid.md.
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.

pricegrab AGENTS.md is an instructions file published in the GitHub repository mablanco/pricegrab (11 stars, last pushed 3d ago), licensed MIT. It adds 1,412 tokens to every session, about $0.0071 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.
