What it does

Valgrind Analysis is an agent skill from InternationalColorConsortium/iccDEV. Build and run iccDEV tool lanes under Memcheck, Helgrind, DRD, Massif, or Callgrind while preserving analyzer evidence.

Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development. It works with GitHub. The repository describes itself as: iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of ICC color management profiles. The licence is BSD-3-Clause.

When your agent uses it

  • Development work in your project

Example prompts

  • “/valgrind-analysis”

Requirements

  • Docker
  • Pre-approved tools (allowed-tools): bash, read, grep, glob, shell(git:*), shell(docker:*)

Workflow steps

12 steps, taken from the first numbered list in SKILL.md.

What it can do on your machine

Read from SKILL.md and the folder at commit 3c2425d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • bash
    • read
    • grep
    • glob
    • shell(git:*)
    • shell(docker:*)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Valgrind Analysis loads about 636 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 261 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~636

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Valgrind Analysis

Use this skill for uninitialized-memory, invalid-access, leak, synchronization, heap-growth, or call-profile investigations against iccDEV tools.

Workflow

  1. Read ../../../docs/valgrind-analysis.md.
  2. Select the smallest registered target that reaches the affected path.
  3. Run .github/ci/valgrind/build.sh --target TARGET to produce a separate non-sanitized Debug build.
  4. Confirm the build rejects cached sanitizer flags and sanitizer-instrumented binaries, including statically linked runtimes.
  5. For runner or image QA, run .github/ci/valgrind/self-test.sh after building the dump target.
  6. Run .github/ci/valgrind/run.sh --tool TOOL TARGET with a bounded timeout.
  7. Preserve the generated summary.tsv, analyzer log, stdout, stderr, and generated work files.
  8. For concurrency, compare Helgrind and DRD rather than treating either as a substitute for TSan.
  9. For issue #2592 or m_jobReady notification changes, run .github/ci/valgrind/issue-2592-regression.sh; require both analyzers to be clean and their generated TIFFs to match.
  10. Attribute findings to stack frames and observed synchronization behavior, not input filenames.
  11. For .icc corpus sweeps, build pawg or dump and use corpus.sh; do not use word-splitting command substitution around find.
  12. Report the exact source revision, command, exit code, error count, and evidence directory.

Use --allow-findings only when collecting a known or deliberately compared finding. Never use it to turn an unexplained result into a clean gate.

Container path

The unified image exposes iccdev-valgrind-build, iccdev-valgrind-run, iccdev-valgrind-status, iccdev-valgrind-validate, and iccdev-valgrind-self-test. These commands write to /workspace/valgrind by default and must not wrap /workspace/build.

The repository's .github/ci/valgrind/corpus.sh supports mounted corpus paths inside the unified image. Preserve per-profile evidence outside the container; prefer tar streaming when a writable bind mount has a different owner.
