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 | $0.00055 | $0.01188 |
| Opus 5.5 | $0.00022 | $0.00475 |
| Sonnet 5.5 | $0.00011 | $0.00238 |
| Haiku 4.5 | $0.00006 | $0.00119 |
Grade A, and why
tbd 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 — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.
tbd Workflow
tbd provides lightweight, git-native task and issue tracking using beads, which are
just lightweight issues managed from the CLI.
Context Recovery: Run
tbd primeafter compaction, clear, or new session. Hooks auto-call this in Claude Code when .tbd/ detected.
SESSION CLOSING PROTOCOL
CRITICAL: Before saying “done” or “complete”, you MUST run this checklist:
[ ] 1. Stage and commit: git add + git commit
[ ] 2. Push to remote: git push
[ ] 3. Start CI watch (BLOCKS until done): gh pr checks <PR> --watch 2>&1
[ ] 4. While CI runs: tbd close/update <id> for issues worked on
[ ] 5. While CI runs: tbd sync
[ ] 6. Return to step 3 and CONFIRM CI passed
[ ] 7. If CI failed: fix, re-push, restart from step 3
NON-NEGOTIABLE Requirements
CI: Wait for --watch to finish
The --watch flag blocks until ALL checks complete.
Do NOT see “passing” in early output and move on—wait for the final summary showing
all checks passed.
tbd: Update issues and sync
Every session must end with tbd in a clean state:
- Close/update every issue you worked on
- Run
tbd syncand confirm it completed
Work is not done until pushed, CI passes, and tbd is synced.
Core Rules
- Track all task work not being done immediately as beads using
tbd(discovered work, future work, TODOs for the session, multi-session work) - When in doubt, prefer tbd for tracking tasks, bugs, and issues
- Use
tbd createfor creating beads - Git workflow: update or close issues and run
tbd syncat session end - If not given specific directions, check
tbd readyfor available work
Essential Commands
Finding Work
tbd ready- Show issues ready to work (no blockers)tbd list --status open- All open issuestbd list --status in_progress- Your active worktbd show <id>- Detailed issue view with dependencies
Creating & Updating
tbd create "title" --type task|bug|feature --priority P2- New issue- Priority: P0-P4 (P0=critical, P2=medium, P4=backlog). Do NOT use "high"/"medium"/"low"
tbd update <id> --status in_progress- Claim worktbd update <id> --assignee username- Assign to someonetbd close <id>- Mark completetbd close <id> --reason "explanation"- Close with reason- Tip: When creating multiple issues, use parallel subagents for efficiency
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.

tbd is a skill published in the GitHub repository jlevy/speculate (34 stars, last pushed 8mo ago), licensed MIT. It adds 55 tokens to every session and 1,188 once invoked, about $0.0002 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 2026-08-30.
