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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
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 | $0.00021 | $0.00460 |
| Opus 5.5 | $0.00008 | $0.00184 |
| Sonnet 5.5 | $0.00004 | $0.00092 |
| Haiku 4.5 | $0.00002 | $0.00046 |
Grade A, and why
source-command-hdd-hdd 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.
What it actually says
source-command-hdd-hdd
Use this skill when the user asks to run the migrated source command hdd-hdd.
Command Template
/hdd (DEPRECATED)
This command is deprecated. Use the /hdd skill at .Codex/skills/hdd/SKILL.md instead.
The skill is the canonical HDD entry point with full sub-agent delegation templates,
spec creation, reconciliation dispositions, and --phases support for /workflow integration.
The module briefs in ./modules/ remain as reference material for sub-agent context.
Original description (preserved for reference)
Run Hypothesis-Driven Development using small delegated modules.
Usage
/hdd <adr-number> "<title>" [--resume]
Instruction Budget
- This orchestrator is router-only and must stay under the orchestrator budget policy.
- Execution details live in phase modules.
Inputs
adr_number(required)title(required)resume(optional)
Delegation
- Research ->
./modules/research-brief.md - Stage ADR ->
./modules/stage-adr-brief.md - Implement ->
./modules/implement-brief.md - Validate ->
./modules/validate-brief.md - Decide ->
./modules/decide-brief.md
Orchestrator Steps
- Initialize or resume state.
- Delegate current phase using the standard handoff schema.
- Collect module output and persist phase result.
- Run user checkpoint after each phase.
- Append delegation trace event.
- Route to next phase until complete.
Checkpoints
- After research: approve hypotheses.
- After stage ADR: approve implementation scope.
- After validate: confirm manual verification findings.
- Before decision: confirm accept/reject action.
Output
- Accepted ADR migrated to production path, or rejected ADR archived with rationale.
- Workflow summary with outcomes and open risks.
- Trace artifact at
.Codex/command-traces/hdd.jsonl.
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.
- 1mo ago First seen · 72 lines · 21 tokens per session scan A 5ac41405d10e
source-command-hdd-hdd is a skill published in the GitHub repository Kastalien-Research/thoughtbox (65 stars, last pushed 3mo ago), licensed MIT. It adds 21 tokens to every session and 460 once invoked, about $0.0001 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.
