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 | $0.00008 | $0.01925 |
| Opus 5 | $0.00004 | $0.00962 |
| Sonnet 5 | $0.00002 | $0.00385 |
| Haiku 4.5 | $0.00001 | $0.00193 |
Grade A, and why
add-spec 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 today.
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 — 208 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Add Spec to Existing Folder
Adds an implementation spec (feature/bug/issue) to an existing spec folder that contains a PRD. Routes to the appropriate generate command with context.
Variables
- $param1: $1 (required) - 10-digit spec ID of existing folder (e.g.,
2511131522)
Instructions
- IMPORTANT: This is a ROUTER command - it does NOT generate specs itself
- IMPORTANT: Read the appropriate generate command instructions and follow them exactly
- This command adds a spec to a folder that already has a PRD (or empty folder)
- Auto-detects spec type from conversation context (feature/bug/issue)
- References existing PRD content if available for better accuracy
- Routes to:
generate-feature-spec,generate-bug-spec, orgenerate-issue-spec
Workflow
-
Validate Spec ID:
- Verify $param1 is a 10-digit number matching format
YYMMDDHHmm - If invalid format: Show error and exit
- Example valid:
2511131522 - Example invalid:
123(too short),abc(not numeric)
- Verify $param1 is a 10-digit number matching format
-
Read Index and Verify Folder:
- Read
.agent/specs/index.json - Look up entry with key matching $param1
- If not found: Show error listing available spec IDs and exit
- Extract folder path from entry
- Verify folder exists at
.agent/specs/{folder} - If folder doesn't exist: Show error and exit
- Read
-
Check for Existing Spec:
- Check if entry has
pathfield in index.json - If
pathfield exists and points tospec.md: Show error "Spec already exists at {path}" and exit - This prevents overwriting existing specs
- Check if entry has
-
Read Existing PRD (if present):
- Check if
prd.mdexists in folder - If exists: Read
prd.mdcontent to use as additional context - If not: Continue without PRD context
- Check if
-
Detect Spec Type:
- Analyze conversation history and PRD content (if available)
- Determine if this is a:
- feature: New functionality, enhancement, or major change
- bug: Fixing broken behavior, errors, or unexpected results
- issue: Small task, minor fix, or simple change
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.

add-spec is a command published in the GitHub repository jnarowski/agentcmd (18 stars, last pushed 8mo ago), licensed MIT. It adds 8 tokens to every session and 1,925 once invoked, about $0.0000 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 2026-09-01.

checklist
Generate a custom checklist for the current feature based on user requirements.
clarify
Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.
specify
Create or update the feature specification from a natural language feature description.
analyze
Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
converge
Assess the current codebase against the feature's spec, plan, and tasks, then append any remaining unbuilt work as new tasks to tasks.md so implement can complete it.
implement
Execute the implementation plan by processing and executing all tasks defined in tasks.md.
