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 | $0.01688 | $0.01688 |
| Opus 5 | $0.00844 | $0.00844 |
| Sonnet 5 | $0.00338 | $0.00338 |
| Haiku 4.5 | $0.00169 | $0.00169 |
Grade C, and why
idd-skill idd-overview-appendix.instructions.md scanned grade C with 1 finding 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.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.
<!-- idd-generated-from: idd-template/.github/instructions/idd-overview-appendix.instructions.md Generated by sync-docs. Edit the source above, then run `node scripts/sync-docs.mjs --apply`; do not edit this file. --> How it starts
The opening of the file, as written. The whole thing — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.
IDD — Reference and Implementation Appendix
This appendix contains reference content, implementation details, and
maintainer guidance for the IDD workflow. The core runtime definitions
are in idd-overview-core.instructions.md.
Policy Constants
The distributed claim, advisory, CI, and critique-loop defaults are
named in docs/policy-constants.md. Read that page before changing any
timing or loop constant, and record local deviations in onboarding or
repository docs so future sessions can find the selected policy values
without scanning every phase file.
Live status digest
The optional live status digest is a human-facing issue or PR comment
whose first line is <!-- idd-live-status: current -->. It summarizes
phase, claim, branch, last-checked time, blockers, and next action. It
is never an authority for IDD state transitions — decide from trusted
operational markers and GitHub state. If multiple marked digests exist,
preserve them, report the URLs, and choose none as authoritative in an
unattended run. See
docs/idd-comment-minimization.md for the contract and the optional
node scripts/live-status-digest.mjs helper (convenience only).
Treat every digest create or edit as a GitHub side effect: re-validate
the active claim first, write fields from the state just collected, and
set Authoritative by to the evidence used. If the claim was lost, do
not repair or update the digest.
On pull requests, a digest edit is still PR activity: do not edit a PR digest between a valid E1 review watermark and an intended F3 merge (it would perturb review-currency). Edit it only when leaving merge intent (returning to E1, routing F3 to F1/D4 as blocked, or a hold/stop) or after F3 has merged; the F3 awaiting-reviewer restart-F2 path skips digest edits for the same reason.
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.

idd-skill idd-overview-appendix.instructions.md is an instructions file published in the GitHub repository kurone-kito/idd-skill (11 stars, last pushed 4d ago), licensed MIT. It adds 1,688 tokens to every session, about $0.0084 per session on Opus 5. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
