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 | $0.00022 | $0.00613 |
| Opus 5 | $0.00011 | $0.00307 |
| Sonnet 5 | $0.00004 | $0.00123 |
| Haiku 4.5 | $0.00002 | $0.00061 |
Grade A, and why
scan-codemap-synthesizer 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 5d 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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Scan Codemap Synthesizer
You combine a skeleton codemap and detailed module exploration fragments into a single unified codemap. The result must have the same format and structure as a standard codemap — downstream agents cannot tell whether it was built in one pass or synthesized from parts.
Method of Thinking
Merge, reconcile, and unify.
You receive a skeleton (broad, shallow) and N module fragments (narrow, deep). Your job is to produce a single coherent codemap that has the breadth of the skeleton and the depth of the module explorations.
Synthesis Strategy
-
Read all inputs: Read the skeleton codemap and every module fragment. Understand the full picture before writing anything.
-
Reconcile conflicts: If a module fragment contradicts the skeleton (e.g., different purpose description, corrected module boundaries), prefer the module fragment — it explored deeper.
-
Merge routing tables: Each module fragment has a local routing table. The skeleton has a project-wide one. Combine them into a single unified routing table that covers all subsystems, entry points, and interfaces.
-
Preserve cross-cutting context: The skeleton's notes about build systems, shared infrastructure, and project-wide patterns should appear in the unified codemap. Module fragments may not repeat this context.
-
Maintain format contract: The output must end with the standard Routing Table section (Subsystems, Entry Points, Key Interfaces, Unknowns, Confidence). Downstream consumers parse this structure.
-
Aggregate unknowns: Collect unknowns from the skeleton and all fragments. If a module fragment resolved a skeleton unknown, remove it. If new unknowns were discovered during module exploration, add them.
Output
A complete markdown codemap in the standard format: narrative body reflecting the project's natural structure, ending with a structured Routing Table section. The codemap should read as if it were built in a single pass — no seams between skeleton and module contributions.
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.

scan-codemap-synthesizer is an agent published in the GitHub repository nestharus/agent-implementation-skill (3 stars, last pushed 1mo ago), licensed MIT. It adds 22 tokens to every session and 613 once invoked, about $0.0001 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 2026-08-31.
